Answer:
y = -1/4x-6
Step-by-step explanation:
y=mx+b
Use slope equation m = (y1 - y2) / (x1 - x2)
b is the y intercept : -6
Answer: 37
Step-by-step explanation: 14 x 3 = 42
42 - 5 = 37
Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39
Hope this helps! :)
7x + 1 = 2(2x - 1) + 3(x + 1)
7x + 1 = 4x - 2 + 3x + 3
7x + 1 = 7x + 1
