First part: 1 is less than the sum of x and 3: 1 < x+3.
Second part: the sum of x and 3 is less than 9.
Obviously 1 < 9.

Taking another look at 1<x+3, we can solve for x: -2<x. Draw a dashed vertical line thru x = -2.
Taking another look at x+3<9, subtract 3 from both sides. Then x<6.
Draw a dashed vertical line thru x=6.

Shade the area between these two vertical lines to obtain the desired graph.

Evaluate 5r-8.35s when r=12 and s=4

balu736 [363]

Answer: 26.6

Step-by-step explanation:

r = 12 5(12) = 60 | s = 4 8.35(4) = 33.4 | Now subtract both total number = 33.4 - 60 = 26.6

Which function represents the quadratic function f(x) = x^2 after a vertical stretch by a factor of number 2?

Zielflug [23.3K]

C is your answer. The coefficient on the x value is always a stretch factor.
