Given the equation: y = 3x + 5, what is the value of ‘y’ when x = 4?

17

Step-by-step explanation:

Input x=4 into the equation

y= 3(4)+5

y= 12+5

y=17

y=17

Step-by-step explanation:

if x=4,

y=3(4)+5

y=12+5

y=17

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
