X^2+8x-3>-19 | +19
x^2+8x+16>0
x^2+4x+4x+16>0
x(x+4)+4(x+4)>0
(x+4)(x+4)^2>0
this is true cause (X+4)^2 >0 cause X+4>0
Answer:
6 =v
Step-by-step explanation:
-5(v - 1) = -6- (1 + 3v)
Distribute
-5v +5 = -6 -1 -3v
Combine like terms
-5v +5 = -7 -3v
Add 5v to each side
-5v+5v +5 = -7 -3v+5v
5 = -7+2v
Add 7 to each side
5+7 = -7+7 +2v
12 = 2v
Divide each side by 2
12/2 = 2v/2
6 =v
<span>The three equations can be written as 1) y = 2x - 5 ; 2) y = 2x - 3 and ;3) y = 2x + 5. Now, the slope can be found by slop intercept form of linear equation i.e. y = mx+b where m is the slope. From the above equations, we can see that all the the three have the same slope i.e. m = 2.</span>
