Answer:
y= -3/2x + 5/2
Step-by-step explanation:
<u>Given:</u>
- Line y= -3/2x - 1 and point (3, -2)
<u>To find:</u>
- Equation for the line parallel to the given that passes through the given point.
<h3>Solution</h3>
The given line has a slope of -3/2
The parallel line will have the same slope
<u>The point-slope form:</u>
<u>We have m = -3/2, y1= -2, x1 = 3, plug in:</u>
- y - (-2) = -3/2(x - 3)
- y + 2 = -3/2(x - 3)
- y = -3/2x + 9/2 - 2
- y = -3/2x + 5/2
or
Where is the rest of the question?
Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
Answer:
28
Step-by-step explanation:
x equals 1
y equals 11
you would plug the numbers in
(1)6 plus (11)2 which if you multiply them
6 plus 22 would give you 28
Answer:
8
Step-by-step explanation:
( 12 + 3m ) / 2 = 18
12 + 3m = 18 x 2
12 + 3m = 36
3m = 36 - 12
3m = 24
m = 24 / 3
m = 8
