Answer:
The coordinates of point E are (-19/4,8)
Step-by-step explanation:
To find this, we use the internal division formula;
The formula is as follows;
(x ,y) = mx2 + nx1/(m + n) , my2 + ny1/(m + n)
From the question;
m = 5 n = 3
x1 = -1 , y1 = -5
x2 = -7 , y2 = 11
Substitute these values;
(x ,y) = 5(-7) + 3(-1)/(3 + 5) , 5(11) + 3(-5)/(5 + 3)
(x , y) = (-35-3)/8, (55-15)/8
(x,y ) = -38/8, 40/8
(x,y) = -19/4, 5
Answer:
Neither, complementary
Step-by-step explanation:
1. 62 + 128 = 190 (Neither)
1. 44 + 46 = 90 (Complementary)
Adding up to 90 is complementary, adding up to 180 is supplementary

according to the question ur algebraic expression is
8-w
Answer: y = 7
Step-by-step explanation:
Step 1) plug in 3 for y and 9 for x in the direct variation formula, which is y = kx
3 = k(9)
Step 2) Solve for k
3 = k(9) (Divide by 9 on both sides)
3/9 = k (Now simplify 3/9)
1/3 = k. So k = 1/3
*just FYI: “k” is the constant of variation.
Step 3) use the equation y = kx and plug in 1/3 for k
y = 1/3x
Step 4) using the equation y = 1/3x, plug in 21 for x.
y = 1/3(21) (1/3*21 is the same as 21/3)
y = 21/3 (21/3 = 7)
y = 7. So that’s you’re answer! When x=21, y=7 because 7 is 1/3 of 21!
Hope this helps! My best wishes to you as you go through school!
