Answer:
1. y = 4x - 27
2. y = -4x - 15
Step-by-step explanation:
If two lines are parallel, then they have the same slope. So, the slope of the line we are looking for needs to be 4. We can start by writing a point-slope equation:
y - y1 = m(x - x1)
We can substitute the values we have, the point we are using is (8, 5) because it needs to be on the line:
y - 5 = 4(x - 8)
We can distribute:
y - 5 = 4x - 32
y = 4x - 27
We are not given the slope-intercept form, so we must divide both sides by two to get it:
y = 1/4 x + 8
A perpendicular line has the slope that is the negative reciprocal of the one that is given. So, the slope of the line would be - 4. We can start by writing a point-slope equation:
y - y1 = m(x - x1)
We can substitute the values we have, the point we are using is (-5, 5) because it needs to be on the line:
y - 5 = -4(x + 5)
We can distribute:
y - 5 = -4x - 20
y = -4x - 15
Answer:
Step-by-step explanation:
The answer is B, if we were to plug all the values of x with its corresponding value of y into the equation, everything matches up
Hope that helps
X needs to be multiplied by the same number each time to get Y. Each time you have to multiply X to get Y, the number you have to multiply by is different. If the relationship was proportional, you could take one number and multiply it by X to get Y.
Ex.
X= 2, 6, 8, 12, 18
Y= 1, 3, 4, 6, 9
The rule there is that you have to multiply X by 2 to get Y.
Hope this helps!
You should try doing this
9 times 100
then divide your answer by 12.
Answer:
27
Step-by-step explanation:
Area of Triangle x 2 = 3 * 3
The reason I did not divide it by 2 is because of how the other triangle is bound to have the same area. Just leave it as it is because later you're going to reach the same answer.
3 * 3 = 9
Rectangle Area = 6 * 3 = 18
18 + 9 = 27
