Question

Use the formula y = 1.5x + 400 to predict the rice weevil population 10 weeks after the beginning of the study.

Answer 1

Any ideas?

Answer 2

A variable is a symbol used to represent one or more numbers.

Replace the letter "x" with the number 10 and simplify to find what y is for that value of x.

Answer 3

$$\Huge y = 1.5x + 400 $$ $$\Huge y = 1.5(10) + 400$$

Answer 4

1.5(10) ? not to the power of ten ?

Answer 5

$$\Huge y = 1.5x + 400 = 1.5*x+400$$

Answer 6

the power of ten would look like this: $$ y = 1.5^x + 400$$

Answer 7

$$\Huge y = 1.5^x + 400 $$
