Answer:
y = - 3, x = 8
Step-by-step explanation:
x - y = 11, x = 11 + y
Lets solve this equation with substitution: 3x + 10y = - 6
3(11+y)+10y=-6
33+3y+10y=-6
13y=-39
y = - 3
x - (-3) = 11
x + 3 = 11
x = 8
Answer:
use the first equation and solve for the variables
Step-by-step explanation:
for example, to solve for x add y on both sides x=11+y and substitute that to the equation
3(11+y)+10y=-6
that should give you -3
then go back to the equation x=11+y
x=11+(-3)
x=8
hope this helps!
Someone pls help me with this!!
Answer:the first one is d and the third one is 65% and I think the second one is 5 hours
Step-by-step explanation:
(PLZ READ )all you have to do to get the answer for the first one is divide for example on D it says 1 and then 5 and 2 and 10 first you divide 1 by 5 then 2 by ten and if they ALL have the same answer then they are proportional even if one does not have the same as All the rest it is not proportional.
and for the third one you can search it up
help me pls ........................
Answer:
The answer is
[tex]y = 3x + 5[/tex]
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ↶
[tex]y = mx + b[/tex]
❃Since we already have the slope, we don't need to solve for that.
➊ First: We are going to find the y-intercept.
[tex]y = mx + b \\ 2 = 3( - 1) + b \\ 2 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: }{5 = b}[/tex]
➋Second: Plug in.
[tex]y = 3x + 5[/tex]

f(x)=x^2 g(x)=(x+3)^2+5 we can think of g as a translated (shifted) version of f. Complete the description of the transformation
Answer:
g(x) is shifted 3 to the left and 5 up
Step-by-step explanation:
I am very horrible at explaining these things, especially why it's 3 to the left and not to the right, but you'll have to trust me on that one.
As far as the 5 up part, you take the function (x+3)^2 and you always add 5, raising every output by 5.

Answer: A.
Step-by-step explanation: This is because a function cannot have two or more x values with the same f(x) value. If this happens, the function does not exist.
A 35 foot ladder is leaning against a building. The base of the ladder is 21 feet from the side of the building. How high does the ladder reach along the side of the building?
Answer:
28 feets
Step-by-step explanation:
Given that:
Height of ladder = 35
Distance between foot of ladder and wall base = 21 feets
The height of the ladder = h
Kindly refer to attachment for diagram illustration :
Using Pythagoras rule :
h² = 35² - 21²
h² = 1225 - 441
h² = 784
h =sqrt(784)
h = 28 feets
Height of ladder along the side of the building = 28 feets

Start by finding the scale of this map. At the actual gym, one side length of the snack stand is 60 feet. On the scale map, it is 20 cm. What is the scale?
Answer:
I actual foot represents 0.01093 foot on paper
Step-by-step explanation:
Given that :
Actual side length of snack stand = 60 feets
Length of side on map = 20cm
Scaie :
60 feet = 20cm
1 foot = (20/60) cm
1 foot = 0.333 cm
1cm = 0.0328084 foot
0.333cm = (0.33 * 0.0328084) = 0.01093 feets
Scale :
I actual foot represents 0.01093 foot on paper

Which expressions are equivalent to
?
1/5x1/5x1/5x1/5
Choose 2 answers:
Answer:
we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.
Step-by-step explanation:
Given the expression
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}=\frac{1\cdot \:\:1\cdot \:\:1\cdot \:\:1}{5\cdot \:\:5\cdot \:\:5\cdot \:\:5}[/tex]
[tex]=\frac{1}{5\cdot \:5\cdot \:5\cdot \:5}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Checking options B and C:
Option B
[tex]\left(5^{-4}\right)^0=1[/tex]
Option C
[tex]\frac{5^1}{5^4}=\frac{5}{625}=\frac{1}{125}[/tex]
Thus, options B and C are not equivalent!
Checking Option A
Option A
[tex]\left(5^{-2}\right)^2[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(5^{-2}\right)^2=5^{-2\cdot \:2}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Now, checking option D
Option D
[tex]5^2\cdot \:5^{-6}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]5^2\cdot 5^{-6}=5^{2-6}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Therefore, we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.

What is 1/2 x -2=2(-x+1)
Answer:
x is equal to one and three fifths, or 1.6
Step-by-step explanation:
[tex]\frac{1}{2}x - 2 = 2(-x + 1)\\\frac{x}{2} - 2 = -2x + 2\\\frac{x}{2} + 2x = 2 + 2\\x + 4x = 4 + 4\\5x = 8\\x = 1.6[/tex]

On a sunny day, Larry notices that his shadow is 24 inches long. If it is 74 inches from the top of his head to the end of the shadow, how tall is Larry?
Answer:
70 inches
Step-by-step explanation:
Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).
74 inches is the hypotenuse of the right triangle
use pythagorean theorem: a^2 + b^2 = c^2
let h = Larry's height
h^2 + 24^2 = 74^2
h^2 + 576 = 5476
h^2 = 4900
h = sq rt 4900
h = 70

At top speed, a fox can cover 7 miles in 12 minutes. If a fox could continue at this rate indefinitely, how long would take the fox to cross the 210 mile trail of the
Sonoran Desert?
Answer:
It would take 6 hours for the fox to cross the 210 mile trail of the Sonoran Desert.
Step-by-step explanation:
210 miles divided by 7 miles is 30 miles. 30 miles multiplied by 12 minutes is 360 minutes or 6 hours.
Answer:
6 hours
Step-by-step explanation:
Not sure if this is correct, sorry if it isnt but basically I did 210/7 and got 30, then 30 x 12 to figureout how long it would take, i got 360 minutes and 360 min = 6 hours
