Answer:
The constant of variation is 5
Step-by-step explanation:
We know direct variation is of the form
y = kx
We know y =25 and x=5
25 = k*5
Divide each side by 5
25/5 = 5k/5
5 = k
Answer:
Happy paws=$20.05. Woof watchers=$16.75
Step-by-step explanation: first you add up the sums of happy pays and woof watchers
"of" means to multiply.
20% * 60
= 0.2 * 60 (since % means divide by 100)
= 12
The first one is 90
The second one is 108
Answer:
y = -
x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x + 2 ← is in slope- intercept form
with slope m = 5
Given a line with slope m then the slope of the line perpendicular to it is
= -
= - 
The line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = -
x + 5 ← equation of perpendicular line
