Answer:

${x}^{2} - 3x - 10 = 0$

Step-by-step explanation:

$x = - 2 \: and \: x = 5 \\ x + 2 = 0 \: and \: x - 5 = 0 \\ ( x + 2)(x - 5) = 0 \\ {x}^{2} + (2 - 5)x + 2( - 5) = 0 \\ \purple { \bold{{x}^{2} - 3x - 10 = 0}} \\ is \: the \: required \: equation.$

Answer:

Step-by-step explanation:

the bone and the steak weigh = 1 5/8 pounds

The bone weighs 7/8

The meat weighs = 15/8 - 7/8

Converting 1 5/8 to an improper fraction gives 13/8

13/8 - 7/8 = 6/8 = 3/4

Suppose that F(x) = x^3 and G(x) = (4x)^3 − 5. Which statement best compares the graphs of F(x) and G(x)?

Rom4ik [11]

We have that
F(x) = x^3 and <span>G(x) = (4x)^3 − 5
so
</span>G(x) = F(4x) -5

the visual effect is
1) shrink horizontally by 1/4
2) shift down by 5

therefore
the answer is the option
<span>D.The graph of G(x) is the graph of F(x) compressed horizontally and shifted 5 units down.</span>
