This answer would be letter C because if you simplify 49/56 divided by seven you get a grand total of 7/8.
<span>d. It does, the points shown on the line would be part of y = −2x.
is the answer let me know if this helped</span>
Answer:
x = −6
Explanation:
5x + 7y = -23
Y = -2x - 11
Substitute -2x - 11 for y in 5x + 7y = -23
5x + 7(−2x − 11) = −23
Simplify both sides of the equation
5x + 7(−2x − 11) = −23
5x + (7)(−2x ) + (7)(−11) = −23 (Distribute)
5x + −14x + −77 = −23
(5x + −14x) + (−77) = −23 (Combine Like Terms)
−9x + −77 = −23
−9x − 77 = −23
Add 77 to both sides
−9x − 77 + 77 = −23 + 77
−9x = 54
Divide both sides by -9
−9x / -9 = 54 / -9
x = -6
Answer:
y = 3x - 8
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
4 - 1 / 4 - 3 = 3/1 = 3
m = 3
b = y-intercept
b = -8
y = mx + b
y = 3x + (-8)
y = 3x - 8
Answer:
y = -x + 4
perp: m = 1
y + 4 = x - 3
y = x - 7
