Answer:
x= 19/4
Step-by-step explanation:
Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as
then the equation relating them is
w =
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w
= 4 ×
= 4 × 2 = 8
w =
← equation of variation
When x = 25, then
w =
=
= 1.6
Answer:
D
Step-by-step explanation:
For a function in the form f(x) = x, we can say:
- the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
- the function -f(x) is the original, flipped over x-axis
<em>keeping the 2 rules in mind, we can say that</em>
<em>vertical stretch by a factor of 3 would make it f(x) = 3x</em>
<em>Then</em>
<em>flip over x-axis would make it f(x) = -3x</em>

answer choice D is right
Answer:
c. narrower and translated down
Step-by-step explanation:
Answer:
5(2a -5 + b)
Step-by-step explanation:
(10a - 25 + 5b) = 5( 2a - 5 + b)
5(b + 2a - 5) = 5(2a - 5 + b)
