Y=9x+50
50 is what he dad gave him that doesn’t change, we know he works and earns $9 but we don’t know how many hours
Answer:
C. 2.25
Step-by-step explanation:
The following information is missing: <em>J is at (-3, 4). K is at (4,-2).
</em>
The x value for point L such that JL and KL form a 3:1 ratio is obtained as follows:
where ratio m:n givesfraction m/(m+n), run is the distance over x-axis between J and K, and xJ is the x-coordinate of J.
- ratio 3:1 means: m/(m+n) = 3/(3+1) = 3/4
Replacing into the equation:
m/(m+n)*run + xJ = 3/4*7 + (-3) = 2.25
Answer: see below
<u>Step-by-step explanation:</u>
12) 2(x + 4) = 8
<u> ÷2 </u> <u> ÷2 </u>
x + 4 = 4
<u> -4 </u> <u> -4 </u>
14) 4w - 2(1 - w) = -38
4w -2 + 2w = -38
(4w + 2w) - 2 = -38
6w - 2 = -38
<u> +2 </u> <u> +2 </u>
6w = -36
<u> ÷6 </u> <u> ÷6 </u>
16) 10(1 - 2y) = -5(2y - 1)
10 - 20y = -10y + 5
<u> +20y </u> <u>+20y </u>
10 = 10y + 5
<u> -5 </u> <u> -5 </u>
5 = 10y
<u> ÷10</u> <u> ÷10 </u>
