Answer: x = 35
Step-by-step explanation:
since its a 90 degree angle the equation is equal to 90
2x + 20(-20) = 90(-20)
2x/2 = 70/2
x = 35
hope this helps :))
Answer:
y=-3x+10
Step-by-step explanation:
Use point-slope form first.
y-y1=m(x-x1)
Plug the numbers into that.
y+2=-3(x-4)
Distribute and simplify to convert it to y=mx+b
y+2=-3x+12
y=-3x+10

Answer: 
-------------------------------------------------------------------------------------------------------------
Given: 
Find: 
Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7. We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.
<u>Plug in the values</u>
<u>Distribute</u>
<u>Add 8 to both sides</u>
Therefore, the final equation that follows the description that was provided in the problem statement is y = 5/7x + 51/7.

The intercept method of graphing is quick and easy.
Find the x-intercept by setting y = 0 and solving for x:
y+1=1/3(x−3) => 0<span>+1=1/3(x−3)
Multiply both sides by 3: 3 = x - 3. Then x = 6, and the x-int. is (6, 0).
Find the y-int by setting x = 0 and solving for y:
</span><span>y+1=1/3(0−3)
Mult both sides by 3: 3y+3 = -3, so that 3y = -6, and y = -2.
Then the y-intercept is (0,-2).
Plot these 2 points. Then draw a line thru them.</span>
