(-4, -1/2)
Step-by-step explanation:
Just by looking at the graph I can estimate that the midpoint of AB is (-4, -1/2) but we can also use midpoint formula to get a for sure answer.
Midpoint Formula: ((x1 + x2)/2, (y1 + y2)/2)
x: (-5 + (-3))/2
-8 / 2
x = -4
y: (-4 + 3)/2
-1 / 2
y = -1/2

Answer:
A. 2
Step-by-step explanation:
When you don't know if a number like 256 is a power of anything, it can work reasonably well to start by simply dividing by the factors you know.
256/2 = 128128/2 = 6464/2 = 3232/2 = 1616 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8The 8th root of 2^8 is 2, choice A.

divide through out by 3:
[tex]y = 4 + \frac{4}{3} x \\ \\ { \boxed{ \boxed{y = \frac{4}{3}x + 4 }}}[/tex]
Answer:
y = 4/3x + 4
Step-by-step explanation:
-4x + 3y = 12
-4x + 3y + 4x = 12 + 4x
3y = 4x + 12
3y/3 = (4x + 12)/3
y = 4/3x + 4

The sum of x and 9 is divided by 3.This can be written as...
Answers
“The sum of x and 9” means you need to add x and 9: x+9
The key is that the entire sum needs to be divided by 3, so you must have parentheses around the x+9.
This gives (x+9)/3
Answer:
(x+9)/3
Step-by-step explanation
x and 9 = x+9
divided by 3 = /3
But maths has a rule: multiply and divide first and then add and subtract.
So you need to add brackets in x+9 to add first.
Therefore, the answer is (x+9)/3

The equation to represent the given phrase is 2p-4=-12.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given phrase is "Negative twelve is four less than twice a number, p."
Here, four less than twice a number, p is
2p-4
The difference is equal to -12.
Now, 2p-4=-12
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose -4 to the other side of an equation, we get
2p=-12+4
2p=-8
p=-2
Therefore, the value of p is -2.

Jae is a real estate photographer. The amount he earns in one week is a linear function of the number of houses he photographs.
If he photographs 2 houses, he earns $315, and if he photographs 7 houses, he earns $1015.
a. Create a linear model for Jae's earnings (y) (in dollars) as a function of the the number of houses he photographs (x), and put
the model in slope-intercept form.
Answers
Equation of a linear function is defined by equation y = mx + b,
where m = slope of the line and b = y-intercept
Linear model representing a function for the earning (y) to photograph the houses (x) will be,
y = 140x + 35
Let the linear equation representing the earnings to photograph the houses,
y = mx + b
If we graph a line with two variables, earnings from photography on y-axis and the number of houses at x-axis,
Slope of the line 'm' = [tex]\frac{\triangle y}{\triangle x}[/tex]
If two points lying on the line are (2, 315) and (7, 1015).
Slope of the line 'm' = [tex]\frac{1015-315}{7-2}[/tex]
= [tex]\frac{700}{5}[/tex]
= 140
Therefore, equation of the line will be,
y = 140x + b
Since, (2, 315) lies on the line,
315 = 140(2) + b
315 = 280 + b
b = 35
Now the equation will be,
y = 140x + 35
Therefore, linear model representing a function of the earning (y) to photograph the houses (x) will be,
y = 140x + 35
