Answer:
k = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Given that r varies directly as p then the equation relating them is
r = kp ← k is the constant of variation
To find k use the condition r = 3 when p = 15, then
3 = 15k ( divide both sides by 15 )
[tex]\frac{3}{15}[/tex] = k , that is
k = [tex]\frac{1}{5}[/tex]
Answer:
k = 1/5

Answer:
Step-by-step explanation:
Slope-intercept equation for line of slope m and y-intercept b:
y = mx+b
y = (-5/4)x + 2
slope = -5/4 = -1.25
y-intercept = 2
4,400 dollars is placed in an account with an annual interest rate of 8.25%. How much will be in the amount after 22 years to the nearest cost?
How do I solve this, with steps please? :)
Suppose that y varies directly with x. When x = -4, y=-14. Determine the value of y when
X=9
Answer:
if x=-4 & y=-14...then x=9 & Y= -1. which is minus 10
Step-by-step explanation:
-4 is 10 under -14. If X=9 then Y= -1.

Angel is saving all of his money for a ticket to Grad Bash. Before he started working, he had $7.50 in his bank account On Saturday, he works 5 hours and earns $42.50 On Sunday, he works 8 hours and earns $68,00
Which of the following functions models Angels savings?
Answer:
The second choice is correct. (f(x) = 8.50x+7.50)
Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

y=−4x−3
y=−2x+1
x=x=x, equals
y=y=y, equals
Answer:
x = -2, y = 5.
Step-by-step explanation:
y=−4x−3
y=−2x+1
Because y is common to both left sides:
-4x - 3 = -2x + 1
-4x + 2x = 1 + 3
-2x = 4
x = 4/-2
x = -2.
So y = -4(-2) - 3
= 8 - 3
= 5 .
