I believe #7 would be 5:13, #8 to be 6:7, #9 to be 13:18, #10 to be 18:5.
I hope this helps.
D. Use FOIL and guess and check to factor the equation
Answer: y = 4x + 1
Step-by-step explanation:
1. Make the equation its parallel to in slope intercept form by subtacting 4x to get -y = -4x+ 2 then dividing both sides by -1 to get y = 4x -2
When dealing with parallel lines thier slopes are ALWAYS the same, so the equation we are making should have the slope of 4.
2. Plug in the corrordinates x and y values and the slope into the point-slope form equation to find the y intercept
(y - (-3)) = 4(x - (-1))
3. Solve for y in slope intercept form:
y + 3 = 4x + 4 ----> y = 4x + 1
x/6+4= 15
Subtract 4 from both sides; 4s cancel each other out
x/6+4-4= 15-4
x/6= 11
multiply both sides by 6 to eliminate fraction (multiply by reciprocal of 1/6)
(x/6)(6)= (11)(6)
x= 66
ANSWER: x= 66
