= 1
When a number has an exponent of 0, the number always becomes/equals 1.
B) because the rate of change is 7, while for A the rate of change is 6 and for C and D the rate of change is 4
Answer:
y + 3 = -6(x + 9) or y = -6x - 57
Step-by-step explanation:
We can use the point-slope form for this situation.
Point-slope form: y - y₁ = m(x - x₁), where m = slope and (x₁, y₁) are given coordinates.
Plug in: y + 3 = -6(x + 9)
This can be changed to the more common slope-intercept form.
Multiply: y + 3 = -6x - 54
Subtract: y = -6x -57
Adult ticket = x
student ticket = y
<span>An adult ticket costs twice as much as a student ticket.
</span>x = 2y
Total earnings is $1040
64x + 132y = 1040
x = 2y ------------------------------ (1)
64x + 132y = 1040 -------------(2)
Sub (1) into (2)
64 (2y) + 132y = 1040
128y + 132y = 1040
260y = 1040
y = 4 ------- sub into (1)
x = 2(4) = 8
Student ticket = $4
Adult ticket = $8
8x + 38
or further simplified
x + 4.75
