12 is your heckling my recking
Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
-3/4 goes between -1 and 0 it is the 3rd line to the left and n would go between positive 0 and 1 on the 3rd line to the right
To evaluate 4y/x for x=8 and y=0 we shall have:
4y/x=(4×0)/8
=0/8
=0
Answer; 0
Answer:
50
Step-by-step explanation:
Angle 1 is 110.
Angle 3 is 2x plus 10.
Angle 1 and 3 are vertically opposite angles.
And vertically opposite angles r equal.
Which means, angle 1=angle 3,and angle 2=angke 4.
Here we only Need angle 2 and 3.
Angke 2= angle 3.
Which is 2x plus 10=110.
Therefore 2x=110-10=100
Therefore x = 100÷2=50
There u have it ma'am.
