Answer:
C
Step-by-step explanation:
The minimum point is (3, -4). Therefore, vertex = (3, -4).
The curve intersects the x-axis at (1,0) and (5,0). Therefore, the x-intercepts are (1,0) and (5,0).
The curve intersects the y-axis at (0,5). Therefore, the y-intercept is (0,5).
As the curve changes from decreasing to increasing at x = 3, there is an axis of symmetry at x = 3.

Answer:
x = 4y + 6
Step-by-step explanation:
x-4y=6
2x-8y=12
multiply 2 on both side in equation 1, and multiple - on both side in equation 2:
2x-4x=12
-2x+8y=-12
so the equation becomes:
4y=0
y=0
put the value of y in both of the equations:
x=6 equation 1
x=6 equation 2
so,
x = x
then,
x = 4y + 6 equation 1
-2 ( x - 4y ) = -12
x - 4y = -12/ -2
x - 4y = 6
x = 4y + 6
so the ans is:
x = 4y +6
If t varies inversely with the speed, the formula for that is
. If t = 2 and r = 40, then we can solve for k, the constant of variation. Multiply both sides by 40 to get k = 80. Now we need to find the value for t when r = 45. Using the k value we just solved for, we will fill in the equation as
for a t value of about 1.78 hours
Answer:
2√30
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
7^2 + b^2 = 13^2
b^2 = 120
b = 2√30
