Hey there! :)
Answer:
16 minutes.
Step-by-step explanation:
Create an equation in the form y = mx + b to solve this problem. Begin by solving for the rate of change of the table using the slope formula:
Plug in values from the table into the equation:
Simplify:
m = 6.
Plug in the slope and a point from the table into the equation
y = mx + b
40 = 6(5) + b
40 = 30 + b
40 - 30 = b
b = 10.
Rewrite the equation:
y = 6x + 10
To solve for how long it took her to ride 1 km, plug 1 into the equation:
y = 6(1) + 10
y = 6 + 10
y = 16 minutes.
Answer:
The answer is C because the domain is all your x-coordinates.
Step-by-step explanation:
The answer to this is 250.
x = 65
Step-by-step explanation:
cos theta = 25/x
cos theta = x/169
25/x = x/169
x² = 169 x 25
x = 65
14 because 28x4=112 112 divided by 8=14 answer=14
