Answer:
81+71+x=180
152+x=180
x=180-152
x=28°
Step-by-step explanation:
Hope that this is helpful.
Have a great Day.
(-2x + 4y)(3x - 7y) = -6x^2 - 28y^2 + 12yx
Answer:
did you ever get help?
Step-by-step explanation:
i wanna know
So you have to first put put the equation in slope-intercept form.
-3x+4y=4
+3x +3x
_______________
4y=4+3x
then you divide 4 by 4 and then divide 3x by 4 and you should get y=1+3/4x
then you plug in x and only x so that you can find y and then do the same once you find y
y=1+ (4)3/4
y= 1+3
y=4
then plug in y and solve for x
4= 1+ 3/4x
subtract 1 from both sides
3=3/4x
divide both sides by 3/4
and x=4
so then you find b and put it all in a equation.
