Step-by-step explanation:
Answer:
B and D
Step-by-step explanation:
First, you have to solve the first equation. (Hint: you use the distributive property.)
2(5x + 2 + x)
10x + 4 + 2x
12x + 4
We can already see that B is correct and A is incorrect.
Now to solve C and D.
C = 2(5x + 3)
10x + 6
This is incorrect.
D = 2(6x + 2)
12x + 4
This is correct.

This is the answer with step by step explanation
Answer:
Step-by-step explanation:
Y-intercept is -2.
Using slope formula, 2-(-2)/2-0 = 4/2 = 2 = slope.
Plugging into slope-intercept form:
y=mx+b => y=2x-2
Answer:
She would pay $2.80 in sales tax.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
Megan paid $2.52 in sales tax on an item that cost $36.00 before tax. How much in taxes for $40.00 before taxes?
$2.52 - $36.00
x - $40.00
Applying cross multiplication



She would pay $2.80 in sales tax.
