Answer:
y= 5x+20
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
The slope is 5 and a point on the line is (-4,0)
Substituting this information into the equation, we can solve for b
0 = 5(-4) +b
0 = -20+b
Add 20 to each side
0+20 = -20+20+b
20 = b
y = 5x+20
M<3 = m<5
10x = 12x - 25
2x = 25
x = 12.5
answer is A. first choice
Answer: 21cm
Step-by-step explanation:
To find the area of a rectangle you just multiply the length by the width. In this case we have 12(width) x ?(length) = 252. To solve we would just divide the area by the known measurement to find the missing one, so 252/12 =21cm
Answer:
10 meters
Step-by-step explanation:
To calculate area of the triangle we multiply height with base and that divided by two
90 = (18 × w) ÷ 2
180 = 18w
w = 10 meters
