Answer:
72
Step-by-step explanation:
(9+9+7^2)-4+9
(9+9+49)-4+9
67-4+9=72
I believe this is correct.
Answer:
(9+9+7^2)-4+9= 72
Step-by-step explanation:
Using PEMDAS, we can solve this problem easily. First, look for parentheses. Inside of the parentheses is an exponent, 7^2. This equals 49. Continuing to solve inside the parentheses, we get 9+9+49= 67. Now, we add and subtract from left to right. Our new equation looks like 67-4+9=?. 67 minus 4 is 63, and 63 plus 9 is 72. Thus, the answer to this equation is 72.
Hope this helps!

10 + 3x= 5 – 2x
What are the steps to finding the answer
Answers
Answer:
x=-1
Step-by-step explanation:
10+3x=5-2x (Add 2x to both sides)
10+5x=5 (Subtract 10 from both sides)
5x=-5 (Divide both side by 5)
x=-1
Answer:
x=-1
Step-by-step explanation:
10 + 3x= 5 – 2x
You first +2x on both sides
10 + 3x+2x= 5 – 2x+2x
subtract 10 on both sides
10-10+5x=5-10
Then divide 5 to isolate x
5 divide 5x=-5 divide 5
x=-1

Why or why not? (You MUST show work to receive full credit!) Part B - – Write an equation to represent the relationship. The formula for the equation is y = kx
Answers
Answer:
65
Step-by-step explanation:
Answer:
(cost) is proportional to (amount of candy) because all of the values of the
ratios comparing cost to pounds are equivalent. All of the values of the ratios
are equal to . Therefore, every measure of (amount of candy) can be
multiplied by the number to get each corresponding measure of (cost).

Write the rule for the linear function. Remember a function rule is written using f(x)
Answers
Answer:
The rule for the linear function will be:
f(x) = 5/2x - 4
Step-by-step explanation:
We know that linear function can be represented using the slope-intercept formula
y = mx+b
where m is the slope and b is the y-intercept
Given the function is linear
Taking two points
(0, -4)(2, 1)Finding the slope between (0, -4) and (2, 1)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [1 - (-4)] / [2 - 0]
= 5 / 2
Thus, the slope of the line = m = 5/2
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = -4
Thus, the y-intercept b = -4
Now, substituting m = 5/2 and b = -4 in the slope-intercept form of linear function
y = mx+b
y = (5/2)x + (-4) ∵ m = 5/2, b = -4
y = 5/2x - 4
or
f(x) = 5/2x - 4 ∵ y = f(x)
Therefore, the rule for the linear function will be:
f(x) = 5/2x - 4

3) Explain why we always get an integer when multiplying a radical expression by its conjugate? Provide your own appropriate example with supporting work that matches your explanation..

Answer:
1) The conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].
2) -111
3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.
Step-by-step explanation:
1) A radical number of the form [tex]r = a + b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], where the first component is a non-radical real number which acts as a "pivot" and the second component is the radical component, which generates a "displacement" from pivot.
The conjugate of [tex]r[/tex] is a real number [tex]s = a - b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], which that is "pivot" plus "displacement" in the direction opposite to that of [tex]r[/tex]. We proceed to complement this explanation with the image attached below.
Then, the conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is Samantha who created part of a table to show her savings. She saved at the same rate each week.
We have, Samantha’s Savings as -
Week 1 2 3 4
Money Saved A B $18 $24
Since she saves at the same rate every week, therefore, the slope of the line will be -
m = (24 - 18)/(4 - 3)
m = 6/1
m = 6
Then -
A = 6
B = 12
The graph [2] represents the correct graph.
Therefore, graph [2] represents the correct relationship between Weeks and Money saved by Samantha.

11. If 2x+19=27, then 2x=8
Answers
Answer:
100% true....
subtracting 19 from both sides brings you to 2x=8, so x=4
Step-by-step explanation:
Hey there!
2x + 19 = 27
SUBTRACT by 19 to BOTH SIDES
2x + 19 – 19 = 27 – 19
Cancel out: 19 – 19 because that gives you 0
KEEP: 27 – 19 because that gives you the value of 8
New EQUATION: 2x = 8
DIVIDE by 2 to BOTH SIDES
2x/2 = 8/2
CANCEL out: 2/2 because that gives you 1
KEEP: 8/2 because that gives you the value of x
“8/2 = x”
Answer: x = 4 ☑️

Answer:
x = 5
Step-by-step explanation:
all angles at corners in parallelogram must add to 360
bcd = 51 thus angle at opposite corner (bed) must also equal 51
adding = 51 + 51 = 102
angles at ebc and edc are also equal to each other
edf = 55 and cbf = 55
adding 55+55 = 110
360 - 110 - 102 = 148
divide by 2 for angles ebf and cfd
148/2 = 74
now solve
14x + 4 = 74
14x = 70
x = 5
