How many solutions does the graph of each system of equations have? Choose the correct label for the solution to each system of equations from the drop-down menus.

Look at picture attached

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
