Solve for x: x – 10 = -15 question 2 options: 5 -5 25 -25

x-10 = -15

add 10 to each side

x=-15+10

x=-5

Choice B

 B. -5 x=-5 *The answer should be the negative sign.*

Step-by-step explanation:

addition property of equality is adding the same number to both sides of an equation does not change the equation.

add by 10 both sides of an equation.

x-10+10=-15+10

simplify by equation.

-15+10=-5

15-10=5

10+5=15

15-5=10

It changes to positive to negative.

x=-5

Hope this helps!

Thanks!

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
