Given that,
f(x) = -3x + 8
To find,
The value of f(x) at x = 4.
Solution,
We have,
f(x) = -3x + 8
We need to find the value of f(x) at x = 4
Pu x = 4 in f(x).
f(4) = -3(4) + 8
= -12 +8
= -4
So, f(4) is equal to -4.

Which equation has the same solution as x2 - 6x - 14 = 0?
Answer:
B
Step-by-step explanation:
Given
x² - 6x - 14 = 0 ( add 14 to both sides )
x² - 6x = 14
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 14 + 9
(x - 3)² = 23 → B

Answer: See explanation
Step-by-step explanation:
1. 4 apples cost $1.59
1 apple would cost $1.59 ÷ 4
1.59 ÷ 4 = 0.3975
0.3975 ≈ 0.40
1 apple would cost approximately 40 cents.
2. 3 apples cost $1.00
1 apple would cost $1.00 ÷ 3
1.00 ÷ 3 = 0.3333
0.3333 ≈ 0.33
1 apple would cost approximately 33 cents.
3. Loose apples are the better buy because 1 apple costs approximately 33 cents while packaged apples cost approximately 40 cents.
4. 15 ounces cost $1.05
1 ounce would cost $1.05 ÷ 15
1.05 ÷ 15 = 0.07
1 ounce would cost 7 cents.
5. 48 ounces cost $2.39
1 ounce would cost $2.39 ÷ 48
2.39 ÷ 48 = 0.0497
0.0497 ≈ 0.05
1 ounce would approximately cost 5 cents.
6. The 48-ounce jar of applesauce is the better buy because 1 ounce costs approximately 5 cents while a 15-ounce jar of applesauce costs 7 cents.
7. 15 ounces cost $1.54
1 ounce would cost $1.54 ÷ 15
1.54 ÷ 15 = 0.1026
0.1026 ≈ 0.10
1 ounce would approximately cost 10 cents.
8. 6 (six 1 ounce) ounces cost $1.15
1 ounce would cost $1.15 ÷ 6
1.15 ÷ 6 = 0.1916
0.1916 ≈ 0.19
1 ounce would approximately cost 19 cents.
9. The larger box of raisins has a lower unit cost of 10 cents.
10. When buying fruits, you might think about the quality of the fruit, the size.. etc.

Could someone help me find the possible THIRD SIDE to the triangle if two sides are given.
1. 4cm, 17cm
2. 24ft, 52 ft
3. 9yd, 33yd
4. 16km, 17km
Answer: ↓↓↓
Step-by-step explanation:
1. 13 < x < 21
2. 28 < x < 76
3. 24 < x < 42
4. 1 < x < 33
To find the number behind the x, just find the difference between the two numbers but make sure it's positive. Finding the number in front of the x, you add the two numbers together. X has to be greater than the smaller number but less than the greater number because to make a triangle, if two sides are added, their sum should be greater than the third side.
Hope that helped!

Write the phrase as an expression. Then simplify the expression.
7 plus the sum of a number x and 5 simplified expression:
Answer:
7+(x+5) (original equation)
x+12 (simplified)
Step-by-step explanation:
So we know the number is x
Since its just an expression we can’t make x equal to anything so the best we can do is simplify the expression given.
so 7 plus the sum of x and 5
7+(X+5)
Mow just simplify it
x+5 is x+5
x+5+7 is 12+x becuase 5+7 is 12 and I combined like terms
x+12
Answer:
Expression: 7+x+5
Simplified: 12+x
Step-by-step explanation:
x2 + 3x + 2 / x + 2

I REALLY REALLY NEED THESE TODAY PLEASE PLEASE HELP THIS IS LIKE THE 100TH TIME I’VE ASKED I’LL GIVE BRAINLIEST
Please find answers in the explanation below
Step-by-step explanation:
4. Each unlabelled opposites are positioned at a 0.5 interval. That means each division in between 0 and 1, 1 and 2, 2 and 3, 3 and 4 are 0.5. So we have 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4
Same idea is applicable on the negative side of the graph. We have 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4.
5. Like 4 above, each unlabelled opposite is positioned at an 0.5 or 1/2 interval.
So we have, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4 (for the positive side) and 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4 (for the negative side).
6a.
A positive number is one greater than zero while a negative number is one lesser than zero. So we have -0.5 and 0.5
6b. -0.4, 0.4
6c. -3.5, -3 1/2

PLEASE HELP HERES CONTEXT FOR THE WORK PLEASE PLEASE HELP: ROSEMARY HONEY VEGAN BREAD RECIPE
(makes 2 loaves)
Ingredients:
1 package (% oz.) of active dry yeast
2 % cup of warm water (110-115 degrees)
O3 Tbsp. of sugar
1-2 teaspoons of Rosemary
1 Tbsp. of salt
2 Tbsp. of Canola Oil
6 4 cups of flour
½ Tbsp. of honey
Preheat oven to 3?5 degrees. In a large bowl add the yeast. Next add the warm water
and watch for the bubbles to form.
Then add your sugar, Rosemary, salt, Canola Oil, and flour. Start to knead your dough
(work the dough with your hands). Form a ball with the dough. Add honey, and nead
the bread some more. The more you knead the dough, the more light and fluffy the
bread wll be beoause this forms more air pockets. I learned this because with my first
batch of bread it turned out very dense. It was still very yummy, but it is much better
if you take extra time and knead the bread so that it is aíry.
Place in bowl and cover. You will let the dough sit for 1 ½ to rise. This is called
proofing. You will notice that the plastic wrap will get foggy. This is okay, and you are
on your way. The dough should rise almost twice its size.
Next, use vegan butter to coat your pan so that your bread does not stick. Form your
bread shape and place in the oven for 30-35 minutes. Set your timer. I always check
mine at 25 minutes, just to see how it is doing. You can turn on the light in your oven
and peek through the oven window. I also noticed that the bread cooking made our
apartment smell really nice and cozy. Bread is a comfort food. When the bell rings, use
your oven mitts or have an adult to remove the bread from the oven. Let cool down for
15-20 minutes. Slice, add butter or jam, and serve to those you lovel
Answer:

suppose a population of unpaired socks is growing exponentially in a closet. At time t=0 (months) there are 4 unpaired socks at time t=4(months) there are 9 unpaired socks. How many unpaired socks will there be after 12 months?
Answer:45
Step-by-step explanation:
Given
at t=0 there are 4 unpaired socks
Suppose at any instant no of unpaired socks are [tex]N=4e^{kt}[/tex]
at t=4(months)
[tex]N=9=4e^{4k}\\e^{4k}=\frac{9}{4}[/tex]
for t=12(months)
[tex]N=4e^{12k}=4(e^{4k})^{3}[/tex]
[tex]N=4\times (\frac{9}{4})^3=\frac{9^3}{4^2}\\N=45.56\approx 45\ \text{unpaired socks}[/tex]
Charlie made a scale drawing of a house and its lot. The scale he used was 1 inch : 3 feet. The actual length of the backyard is 54 feet. How long is the yard in the drawing?
Answer:
The yard in the drawing is 18 feet long
Step-by-step explanation:
The computation of the long yars in the following is as follow:
Given that
Scale used be 1 inch : 3 feet
And, the actual length is 54 feet
So, the long it would be
= 54 feet ÷ 3 feet
= 18 feet
Hence, The yard in the drawing is 18 feet long

A parallelogram has side lengths of 13 and 17 and an angle that measures 64°. Parallelogram W Y Z V is shown. The lengths of W V and Y Z are 13 and the lengths of W Y and V Z are 17. A diagonal is drawn from point V to point Y. The length of V Y is x. Angle V W Y is 64 degrees. Law of cosines: a2 = b2 + c2 – 2bccos(A) What is x, the length of the diagonal, to the nearest whole number? 16 18 19 21
Answer:
[tex]16\ \text{units}[/tex]
Step-by-step explanation:
[tex]WV=13\ \text{units}[/tex]
[tex]WY=17\ \text{units}[/tex]
[tex]\angle VWY=64^{\circ}[/tex]
[tex]VY=x[/tex]
From cosine rule we have
[tex]x=\sqrt{WV^2++WY^2-2WV\times WY\cos \angle VWY}\\\Rightarrow x=\sqrt{13^2+17^2-2\times 13\times 17\times \cos 64^{\circ}}\\\Rightarrow x=16.25\approx 16\ \text{units}[/tex]
Length of [tex]x[/tex] is [tex]16\ \text{units}[/tex].

Answer:
112.5 miles.
Step-by-step explanation:
2 cm = 25 miles
The question is asking you for the distance between two cities, and is giving you the information that it's 9 cm on the map.
2 cm + 2 cm + 2 cm + 2 cm = 8 cm
25 divided by 2 is 12.5, which would give you 1 cm for the map key.
2 cm + 2 cm + 2 cm + 2 cm + 1 cm = 9 cm
25 miles + 25 miles + 25 miles + 25 miles + 12.5 miles = 112.5

There are 5 red marbles and 7 blue marbles in a bag What is the ratio of blue marbles to red marbles?
Answer:
5:7
Step-by-step explanation:
For how many red are there blue, is the simple form of this question. In this case the numbers are small for simplifying it but if you wanted to you could do 2.5:3.5 its the same thing, also 10:14 would be right as well as long as the numbers are proportionate. For the smaller simplification i just divided both numbers in half and for the second i doubled them
What type of correlation/association exists?
The number of hours you sleep in and the number of hours you are awake during the day
Answer:
Negative Correlation
Step-by-step explanation:
there is a negative correlation between the number of hours you sleep in and the number of hours you are awake during the day as the longer you are either awake or asleep the less time you will be doing the other thing
Here is a graph I made that will hopefully help you understand.
Even if I switched around the label for the x or y-axis, the correlation would still remain the same because the more you stay asleep, the less you will be awake and vice versa.
