Answer:
x = -13
Step-by-step explanation:
Given that:
9-2x=35
Adding 2x-35 on both sides we get:
9 - 35 = 2x
-26x = 2x
Dividing both sides by 2
-13 = x

Answer:
(2,7)
Step-by-step explanation:
y=6x-5
y=x+5
Since they are both equal to y, set them equal to each other
6x-5 = x+5
Subtract x from each side
6x-x-5 = x+5-x
5x-5 = 5
Add 5 to each side
5x-5 +5 = 5+5
5x=10
Divide by 5
5x/5 = 10/5
x=2
y = x+5
y = 2+5
y =7
Step-by-step explanation:
cosB=4/5
B=36.86°
Hope it helps u
Let's check the dot product .
v.w = 5(4)-2(10) = 20 -20 =0
So the dot product is not 20 . And since the dot product is zero, so they are perpendicular.
And the y component of w is 10.
So correct options are first and third .
