Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X

Answer:
y = 3x+4
Step-by-step explanation:
Use the coordinates of the points to find the slope of the line passing through them.
slope = Δy/Δx = (10-4)/(2-0) = 6/2 = 3
Point-slope equation for line of slope 3 that passes through (0,4):
y-4 = 3(x-0)
Slope-intercept form of the equation:
y = 3x+4
Set x's equal
21x +35y = 7
21x + 12y = -39
Subtract from one another
23y = 46
Divide
y = 2
Hope this helps ;)
