Answer:
r = 40 miles / hour
Step-by-step explanation:
<em><u>Formula</u></em>
d = r * t
<em><u>Givens</u></em>
d = 16 miles
t = 24 minutes = 24/ 60 minutes in an hour = 0.4 hours
r = ???
<em><u>Substitute and solve</u></em>
16 miles = r * 0.4 hours Divide by 0.4
16/0.4 = r Switch sides
r = 16/0.4
r = 40 miles / hour
Slope is equal to rise over run. In this case there is a point at (0,-5), and (12,3). The change in the y is positive 8, and x positive 12. Because of the slope formula change in y over change in x, you could write this as 8/12, or 2/3. The equation would then be
y=2/3x-5
Similar figures are figures of the same shape but different (or same) size.
Thus, they look the same, but one is bigger than the other by a scale factor.
Congruent figures are figures of the same shape AND same size.
They can be mapped onto each other using any type of transformation (besides dilations).
Similar figures can be dilated.

Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
