X=0
i simply just did
x+7=x^2+2x+7
-7 -7
x=x^2+2x
then i just isolated the variable. the only number that could fit was 0
The measure of A is 30 degrees
explanation:
(6x-18)+(14x+38)=180
x=8
6(8)-18=30
Answer:
y + 10 = 7/8(x - 4)
or
y = 7/8x -27/2
Step-by-step explanation:
Parallel lines have the same slope. This enables that they never cross. The slope of the line y = 7/8x - 3 is 7/8. So the slope of the parallel line is also 7/8.
Substitute m = 7/8 and (4,-10) into the point slope form of the line:
y - -10 = 7/8 (x - 4)
y + 10 = 7/8(x - 4)
Simplify to get the equation in y = mx+b.
y + 10 = 7/8 x - 28/8
y + 10 = 7/8x -7/2
y = 7/8x -27/2
Answer:
SR = 5
Step-by-step explanation:
We know that the two lines are equal to each other and thus TS + SR = 13
So, we can simply set the two equations of the first line equal to 13:
x + 2 + 2x - 7 = 13
3x - 5 = 13
3x = 18
x = 6
Now we plug in 6 for x in the SR equation:
2 * 6 = 12 - 7 = 5
