In the slope intercept form equation of a line (y=ax+b) a represents the slope, and b represents the intercept, which is -5. Thus, we know y=ax-5. The slope can be found by creating a fraction with the change in y value on top, and the change of x value on the bottom. If we have two points (4, 1) and (0, -5) we can put this into a fraction -
, which simplifies down to -6/-4, or 3/2. Thus the answer is f(x)=
x-5<span />
(-8x)<span> ÷ (-4)=0
First you have to divide both sides by -4:
2x</span><span> ÷ 1=0
Now divide both sides by 1 so that the left side can be eliminated:
2x=0
</span>Now divide both sides by 2 so that the left side only has x:
x=0
A = 34°
C = 87°
B = 34°
Answer:
B is 34° because its a right triangle (90, 45, 45) so < A and < B are equals.
-4x - 7 +10x = -7 + 6x
Combine like terms on left side.
6x - 7 = -7 + 6x
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
This means there are infinitely many solutions.
Remark
The five is after the decimal point. The 10 in that form is tenths. It represents a number in the denominator. So you would write it as 5/10 and say it as 5 tenths.
The answer is D.
