Answer:
3:1 or 3
Step-by-step explanation:
the left triangle is scaling up to the right triangle. 5/15 is 1/3
7/21 is 1/3
4/14 is 1/3
since it is scaling UP, the scale factor is 3:1
Answer:
Slope is 40
Full equation: y=40x-586
Step-by-step explanation:
Slope is y2-y1/x2-x1
14 is x1
-26 is y1
15 is x2
14 is y2
14-(-26)/15-14
40
So the slope is 40
To find the equation
y=40x+b
14=15(40)+b
14=600+b
b=-586
Equation:
y=40x-586
The answer is A) because the parabola is less than 3 (open circle) and the line is greater than and equal to 3 (closed circle)
Answer:
<h2>h= -3</h2><h2 />
Step-by-step explanation:
25h + 40 = −15h − 80
25h + 15h = -80 - 40
40h = - 120
h = -120/4
h= -3
