Answer:
q = 4
Step-by-step explanation:
given p and q vary inversely then the equation relating them is
p = ← k is the constant of variation
to find k use the condition p = 29 when q = 16 , then
29 = ( multiply both sides by 16 )
464 = k
p = ← equation of variation
when p = 116 , then
116 = ( multiply both sides by q )
116q = 464 ( divide both sides by 116 )
q = 4
Answer:
(5, )
Step-by-step explanation:
Given the 2 equations
5x + 7y = 40 → (1)
3x - 7y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
8x + 0 = 40
8x = 40 ( divide both sides by 8 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
5(5) + 7y = 40
25 + 7y = 40 ( subtract 25 from both sides )
7y = 15 ( divide both sides by 7 )
y =
solution is (5, )
Answer:
70
Step-by-step explanation:
Answer:
okay gonna assume the dilation scale factor is 0.5, not -0.5
A' is at point (2,1)
B' is at point (3,1)
C' is at point (3,2)
D' is at point (2,3)
Step-by-step explanation:
make all of the sides of the model smaller by multiplying by 0.5. Then keep point A' where point A is because the center of the dilation is at point A.
