13.Question- Write an expression using division and subtraction with a difference of 3.
answer- (12 divide 3) -1
Twelve divided by three is four. Four minus 1 is three.
12. Question- Write an expression using multiplication and addition with a sum of 16.
answer- There are many answers for this and this is one of them:
Y=4(3+1)
Y=16
or
Y=2(6+2)
Y=16
11. Question- Sam bought two CDs for $13 each. Sales tax for both CDs was $3. Write an expression to show how much Sam paid in all.

Answer:
The answer to your question is x - 5 or x = 5
Step-by-step explanation:

1.- Factor the numerator
x² - 3x - 10
find 2 numbers that added equal -3 and multiply equal -10.
These numbers are -5 and + 2
(x - 5)(x + 2)
2.- Simplify

Delete (x +2) in both numerator and denominator
3.- Result x - 5
x = 5
Answer:
B and E are the correct answers.
Step-by-step explanation:
By using the slope formula of y₂₋y₁ / x₂₋x₁ you can find out that the slope is ₋7/4.
Next pick a point to put into point-slope form.
Point-slope form is y₋y₁ = m(x₋x₁) where y₁ and x₁ are a point on the graph and m is the slope.
Substitute both points into the formula (separately) to get B and E as your answers.
Hope this helps!
