Solve each quadratic equation by factoring with grouping. 5v2 – 18v = -9

djyliett [7]

Answer:

v = 3 , 3/5

Step-by-step explanation:

$5 {v}^{2} - 18v + 9 = 0 \\ 5 {v}^{2} - 3v - 15v + 9 = 0 \\ v(5v - 3) - 3(5v - 3) = 0 \\ (5v - 3)(v - 3) = 0 \\ v = 3 \\ v = \frac{3}{5}$

5x + 6(x - 2) - 8 (x - 3)

Alex Ar [27]

Answer:

The value of $x=-4$ . The figure is also attached below.

Step-by-step explanation:

Considering the expression

$5x + 6(x - 2) - 8 (x - 3)$

If we have to find the vale of $x$ , then

$5x + 6(x - 2) - 8 (x - 3)=0$

$5x+6x-12-8\left(x-3\right)=0$

$5x+6x-12-8x+24=0$

$3x+12=0$

$\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}$

$3x+12-12=0-12$

$3x=-12$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3x}{3}=\frac{-12}{3}$

$x=-4$

Therefore, the value of $x=-4$ . The figure is also attached below.

Answer:

yintercept: (0,3) or 3

x intercept: (-4,0) or -4

Step-by-step explanation:

The y intercept is what you get when x=0

.75*0+3

The x intercept is what you get when y=0

0=.75x+3

-3=.75x

-4=x
