Answer:
1) y=8/3=2 2/3 2) x=4 3) x+10
Step-by-step explanation:
1) 10+5-7=3y
Calculate the sum or difference.
8=3y
Swap the sides of the equation.
3y=8
Divide both sides by 3.
y=8/3=2 2/3
2) -10x+5x+5=-15
Collect like terms.
-5x+5=-15
Move the constant to the right-hand side and change the sign.
-5x=-15-5
Calculate the difference.
-5x=-20
Divide both sides by -5.
x=4
3) 3x+2x-4x+10
Collect like terms.
(3+2-4)x+10
Calculate the sum or difference.
1x+10
When the term has a coefficient of 1, it doesn't have to be written.
x+10
Hope this helps :)
Answer:
C
Step-by-step explanation:
Let f(y)=x.

Answer:
The homework grade, to the nearest integer, for a student with a test grade of 68 is 69.
Step-by-step explanation:
The general form of the linear regression equation is:

Here,
<em>y</em> = dependent variable = test grade
<em>x</em> = independent variable = homework grade
<em>a</em> = intercept
<em>b</em> = slope
Compute the value of <em>a</em> and <em>b</em> as follows:

The linear regression equation that represents the set of data is:

Compute the value of <em>x</em> for <em>y</em> = 68 as follows:


Thus, the homework grade, to the nearest integer, for a student with a test grade of 68 is 69.
The answer of 3 × 1 3\4 is 21\4 or 5 1/4
