needs halp wit dis uuuuhhhhhhh question, hhhhhhhhhhh i hate math-
Given:
3x(x - 2) + 2 and 2x² + 3x -12
If x = 7 then,
= 3(7)(7 - 2) + 2
= 21(5) + 2
= 107
= 2(7)² + 3(7) -12
= 2(49) + 21 -12
= 98 + 9
= 107
For x = 7, each expression has a value of 107.
If x = 2 then,
= 3(2)(2 - 2) + 2
= 6(0) + 2
= 2
= 2(2)² + 3(2) -12
= 2(4) + 6 -12
= 8 - 6
= 2
For x = 2, each expression has a value of 2.
These results suggests that the expressions are equivalent, but (I don't know the choices) the expressions are equivalent.

Answer: 3.88 to 219
Step-by-step explanation: ok so if the data is O+ donors to B+ donors and you have to write the comparison in three different ways then you look on the chart to see that O+ is 97 & B+ is 25 then it would be 97 to 25. 97 t0 25 & 25 to 97 So I’m thinking next you have to divid 97 by 25 to get 3.88 to 219 .
I might be wrong and if I am i’m sorry.

Write in slope-intercept form the equation of a line passing through the point and perpendicular to the given line.
(8, 2); y = -2x + 4
A. y = 1/2x -2
B. y = -2x + 18
C. y = 1/2x - 6
D. y -2 = 1/2(x - 8)
Answer:
A is your answer.
Step-by-step explanation:
Perpendicular is opposite and reciprocol of the slope. Your slope is -2 so the opposite of that is positive 2, and the reciprocol is 1/2. When you graph that you should have a point at (8,2). y=1/2x -2

There are 88 seats in a theater. The seating in the theater is split into 4 identical sections. Each section has 14 red seats and some blue seats.
a. Create an equation to represent this situation.
b. How many blue seats are in the theater?
c. How many red seats are in the theater?
If there's 14 red seats in each section, the total amount of red seats will be 14 times the 4 sections, which equals 56. We just subtract 56 from 88, which is equal to 32.
An equation for this would look like:
x+56=88
so:
a. x+56=88
b. 32 blue seats
c. 56 red seats
Answer:
a- (88/4) / 14 = Blue seats or red seats? maybe...
b- 56
c-56

The graph shows the the number of jars that are filled by machine A and machine B. Which statement is true about the unit rates shown in the graph?
-----------------------------------------------------------------------------------------
The unit rate for machine A is greater because the slope is greater than the slope for machine B.
The unit rate for machine B is greater because the slope is less than the slope for machine A.
The unit rate for machine A is greater because the slope is less than the slope for
machine B.
The unit rate for machine B is greater because the slope is greater than the slope for machine A.
Answer:
a
Step-by-step explanation:
a presents that the a machine is better therfore i think its a.
hope this helps
The unit rate for machine [A] is greater because the slope is greater than the slope for machine B.
What is slope?Slope of a straight line is used to define the rate of change of [y] with respect to [x].
Given are the graphs that show the the number of jars that are filled by machine A and machine B.
Slope in this case represents the number of jars filled per minute by machine A and machine B. Mathematically, we can write slope as -
m = dy/dx
Now, the ratio of [y] and [x] is equal to tanθ. So, greater the angle θ made by the line with the +x axis, greater will be its slope which in turn will represent the greater number of jars filled per minute.
It can be seen that the angle made by the straight line representing machine A makes greater angle then in the case of machine B.
So, the unit rate for machine [A] is greater.
Therefore, the unit rate for machine [A] is greater because the slope is greater than the slope for machine B.

Which set of statements explains how to plot a point at the location (Negative 3 and one-half, negative 2)?
A. Start at the origin. Move 3 and one-half units right because the x-coordinate is Negative 3 and one-half. Negative 3 and one-half is between 3 and 4. Move 2 units down because the y-coordinate is -2.
B. Start at the origin. Move 3 and one-half units down because the x-coordinate is Negative 3 and one-half. Negative 3 and one-half is between -3 and -4. Move 2 units left because the y-coordinate is -2.
C. Start at the origin. Move 3 and one-half units down because the x-coordinate is Negative 3 and one-half. Negative 3 and one-half is between -3 and -4. Move 2 units right because the y-coordinate is -2.
