V^2-8v=0 solving quadratic equation

Mathematics

1 answer:

solong [7]3 years ago

8 0

Answer:

v = 0, or v = 8

Step-by-step explanation:

The quadratic can be factored, then the zero product rule applied.

v^2 -8v = 0

v(v -8) = 0

A product will be zero when any of the factors is zero. So, the solutions are values of v that make the factors be zero.

v = 0

v -8 = 0 . . . ⇒ . . . v = 8

Solve the inequality –1 > –2(x – 4) – 5(4x – 7).

Ksivusya [100]

Answer:

$x > 2$

Step-by-step explanation:

$–1 > –2(x – 4) – 5(4x – 7)$

$–1 > –2x + 8 –20x + 35$

$–1 > - 22x + 43$

$- 1 - 43 > - 22x$

$- 44 > - 22x$

$\frac{ - 44}{ - 22} < \frac{ - 22x}{ - 22}$

$2 < x$

$x > 2$

Answer: y=6

Step-by-step explanation:

Let's solve your equation step-by-step.

30y+40=220

Step 1: Subtract 40 from both sides.

30y+40−40=220−40

30y=180

Step 2: Divide both sides by 30.

30y/30= 180/30

y=6
