Answer:
a) 8
b) -4
c) 3x² - 4x + 8
d) 20
e) 28
Step-by-step explanation:
a) (-2)² + 4 = 8
b) 8 + [4(-2) - 4] = 8 + (-8 - 4) = 8 + (-12) = -4
c) 3(x² + 4) = 3x² + 12
3x² + 12 - (4x - 4) = 3x² - 4x + 8
d) g(2) = 4 4² + 4 = 20
e) f(2) = 8 4(8) - 4 = 28

For a National Junior Honor Society Induction Celebration, Ahmed is renting tables and chairs. He wants to have only tables for 4 and tables for 6. The total number of people that can be seated in the school cafeteria with these tables is 160.
Write an equation to represent the situation. Let x represent the number of 4 seat tables and y represent the number of 6 seat tables.
Answer:
There are different combinations you can do.... for example
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
so Im not sure which :/ but the equation would be:
10x+20y=160
or
25x+10y=160
there are different combinations of the two so im not sure T_T
This question is based on the concept of linear equation. Therefore, the equation would be, 10x+20y=160 or 25x+10y=160 to represent the situation.
Given:
He wants to have only tables for 4 and tables for 6. The total number of tables is 160.
And x represent the number of 4 seat tables and y represent the number of 6 seat tables.
We need to determined an equation to represent the situation.
Let x represent the number of 4 seat tables and y represent the number of 6 seat tables.
According to the question,
There are different combinations we can make as below,
For example :
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
Therefore, the equation would be, 10x+20y=160 or 25x+10y=160 to represent the situation.

Mackenzie picks some apples.
She eats 3 apples.
Now she has 9 apples.
How many apples did Mackenzie pick to start?
A. 3 apples
B. 6 apples
C. 9 apples
D. 12 apples
Answer:
d.12
Step-by-step explanation:
its saying she ate 3 an now has 9. so you really add 3 to 9 an your answer is 12. in other words x=9+3 for your level of math. i'll be glad to help her with her home work for now if you would like me to.
Answer: Option D 12 apples
Step-by-step explanation:
SOOOO
She ate 3 apples and after that, she left with the 9 apples
They asked how many did Mackenzie pick.
SO its past tense
we have to add 3 apples that she just ate
so 9+3= 12 apples
I think your teacher is wrong because I think your teacher thought that she had 9 apples actually she has 9 apples after she just ate. So if it was before she has eaten the apples then it would be 6
Tell the teacher that she/he is wrong and give this explanation
I hope this helps you and your teacher
Find the slope of the line.
Answer:
The slope is 1/3
Step-by-step explanation:
Slope is rise over run. Starting from the point (1,-4), the line moves up one unit (rise=1) and then 3 units to the right (run=3) to get to the point (4,-3). Therefore rise over run, or the slope, is 1/3.

Answer:

Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (4, 2) and (x₂, y₂ ) = (1, - 2)
d = [tex]\sqrt{(1-4)^2+(-2-2)^2}[/tex]
= [tex]\sqrt{(-3)^2+(-4)^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
= 5
