Answer:
y = 7x
y = 2x -3
y = 3
x = -2
Step-by-step explanation:
- <em>Slope-intercept form: y= mx+b</em>
- <em>Parallel lines have same slope</em>
a)Parallel to y=7x+2 through the point (0,0)
<u>
This line will have a form:</u>
<u>Considering the given point of (0,0), to find the value of b:</u>
<u>The line is: </u>
b)Slope of 2 through the point (0,−3)
<u>
Solving as above:</u>
- y= 2x + b
- -3 = 2*0 + b ⇒ b = -3
- y = 2x -3
c)A horizontal line through the point (0,3)
<u>
A horizontal line will have constant value for y for any value of x:</u>
d)A vertical line through the point (−2,0)
<u>A vertical line will have constant value of x for any value of y:</u>
The answer is b hopefully I helped
If x=mx-3 (which is not clear from your input),
3
then x-mx = -3, or mx-1x = 3, and x(m-1) = 3, and so x = ---------
m-1
24 x 100 = 2400
2400 divided by 60 = 40

Answer: 9</h3>
================================================
Work Shown:
a = unknown = leg #1
b = 12 = leg #2
c = 15 = hypotenuse
Plug those values into the pythagorean theorem and solve for 'a'
a^2 + b^2 = c^2
a^2 + (12)^2 = (15)^2 .... substitution
a^2 + 144 = 225
a^2 = 225 - 144 ... subtracting 144 from both sides
a^2 = 81
a = sqrt(81) .... applying square root to both sides
a = 9
