Answer:
D. 7
Step-by-Step Explanation:
To solve this problem, we need to know a certain equation: the equation of a line in the slope-intercept form:
y = mx + b; where m = slope and b = y-intercept.
First, substitute the known values into the equation. I will use the coordinate (3, 19) for x and y values.
y = 19
m = 4
x = 3
b = ?
19 = (4)(3) + b
Then, all we have to do is solve for b.
19 = (4)(3) + b
19 = 12 + b
19 - 12 = 12 + b - 12
7 = b
So, the y-intercept of the line is 7.
Hope this helps!
Answer:
Length= 8, Width= 4
Step-by-step explanation:
Say the length is l, and the width is w.
We can set l, the length as 2w, as it is double the length.
The perimeter= 2l + 2w= 24
Input l as 2w, get
4w+2w=24
6w=24, w=4.
Length is w*2, so length is 8.

Answer:
17 feet
Step-by-step explanation:
The sum of the three side lengths is the perimeter.
s + s + 11 = 45
2s = 34 . . . . . . subtract 11
s = 17 . . . . . . . . divide by 2
Each of the other two sides is 17 feet.

The answer is 0.02
All you have to do is divide 1 by 50. You can think of it as if it was divided by 100. If you multiply the numerator and denominator by 2 you get 2/100 which is 0.02
