Which of the following are like terms in this expression? 12a-7+7a+12b

Step-by-step explanation:

in order to be like terms, they have to have the same variable (and exponent, if there is any)or be just a constant with no variables (just a number)

like terms in 12a - 7 + 7a + 12b are :

12a and 7abecause they have the exact same variable (a)

12bno like terms

-7...no like terms

so ur answer is : 12a and 7a

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
