Step-by-step explanation:
The 2 angles form a right angle, thus their sum is 90°, hence
4x + 7 + 35 = 90
4x + 42 = 90 ( subtract 42 from both sides )
4x = 48 ( divide both sides by 4 )
x = 12

To calculate the slope m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 4) ← 2 points on the line
m = =
= 4

<u>Step 1: Substitute x from the second equation into the second one</u>
<u>Step 2: Substitute y into the second equation</u>
Answer:
Answer:
Step-by-step explanation:
First move x terms and numbers on one side, keep y on the other side.
y = mx+b is the form
18x -17y = 18
subtract 18x from both sides
-17y = 18 - 18x
divide both sides by -17
y = -18/17 + 18/17x
