Answer:
The answer is D, 30.4
Step-by-step explanation:
Because the two parallelograms are similar, the relationship between the sides of them are directly proportional.
So:
Cross multiply
8x = 243
÷8 both sides
x = 30.375 ≈ 30.4
The answer is D, 30.4
Answer:
-1/2
Step-by-step explanation:
Answer: 8.525
Step-by-step explanation:
Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.
