How do i solve this ons

x=1, y=−4

Step-by-step explanation:

Divide each term by −2 and simplify.

x=−7y/2−13

7x+5y=−13

Replace all occurrences of x with −7y/2−13 in each equation.

−39y/2−91=−13

x=−7y/2−13

Solve for y in the first equation.

y=−4

x=−7y/2−13

Replace all occurrences of y with −4 in each equation.

x=1

y=−4

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
