Answer:1.5 hours
Step-by-step explanation:
$8.50 is for 1/2 hour
In $25.50, the can use for (25.5*.5)/8.5 = 1.5 hours
Answer:
difference between linear equations and inequalities is the solution set. A linear equation of two variables can have more than one solution. For instance, with x = 2_y_ + 3, (5, 1), then (3, 0) and (1, -1)
Step-by-step explanation:
<h3>
Answer: Choice B</h3>
The parent function y = sqrt(x) has the point (0,0) on it. When we subtract 3, we get y = sqrt(x)-3 which moves the point (0,0) three units down to get to (0,-3)
So (0,-3) is one point on y = sqrt(x)-3
The slope:
Look at the picture.
6 units down → -6
2 units right → 2
<h3>Answer: Slope = m = -3</h3>
Answer:
base length = 19 cm , height = 12 cm
Step-by-step explanation:
Area formula : A = (1/2)*b*h
b = h + 7 cm
A = 114 sq. cm
114 = (1/2) * (h + 7) *h
228 = hh + 7h
hh + 7h - 228 = 0
h = -7/2 + root( 49 - 4*(-228)) /2
h = -7/2 + 31/2
h = 24/2 = 12 cm
base = 12 cm + 7 cm = 19 cm
