5/x = -9
5 = -9x (we have multiplied x out from the denominator)
5/-9 = x (divided by -9 to isolate x)
2/3x=10
x=10÷2/3
x=10×3/2
x=5×3
x=15
Answer: D. 28
Step-by-step explanation:
The 3 interior angles of a triangle always add up to 180
Soooo:
95 + 57 = 152
180 - 152 = 28
Point t slope form:
y + y value = m (x + x value) where m is the gradient
Parallel line must have the same gradient as the two lines never meet, so the gradient must be 4. This eliminates option B and D.
Remember that point-slope form is still an equation, so the values of both sides must be equal. So let's substitute the given coordinates.
Option A:
y-6=4(x+2)
-6-6 (-12) does not equal to 4(-2+2) (0)
Option C:
y+6=4(-2+2)
-6+6 (0) = 4(-2+2) (0)
Therefore, option C is your answer.
