Answer:

$\boxed{\bold{x=-\frac{7}{3}}}$

Step-by-step explanation:

Expand: $\bold{5\left(2x\right): \ 10x}$

Expand: $\bold{7\left(x-1\right): \ 7x-7}$

$\bold{10x=7x-7}$

Subtract 7x From Both Sides

$\bold{10x-7x=7x-7-7x}$

Simplify

$\bold{3x=-7}$

Divide Both Sides By 3

$\bold{\frac{3x}{3}=\frac{-7}{3}}$

Simplify

$\bold{x=-\frac{7}{3}}$

Can someone please help me with these two questions

Anarel [89]

Answer:

23. 0.4583 seconds

24. 0.0107 seconds

Step-by-step explanation:

The problem statement tells you how to work it. You need to convert speed from miles per hour to feet (or inches) per second.

90 mi/h = (90·5280 ft)/(3600 s) = 132 ft/s = (132·12 in)/s = 1584 in/s

23. The time it takes for the ball to travel 60.5 ft is ...

time = distance/speed

time = (60.5 ft)/(132 ft/s) = 0.4583 s

It takes 458.3 milliseconds to reach home plate.

24. time = distance/speed

time = (17 in)/(1584 in/s) = 0.0107 s

The ball is in the strike zone for 10.7 milliseconds.

Find the inverse of 2∛(x+2)

Artemon [7]

$y=2\sqrt[3]{x+2}\ \ \ |divide\ both\ sides\ by\ 2\\\\\sqrt[3]{x+2}=\dfrac{y}{2}\to x+2=\left(\frac{y}{2}\right)^3\ \ \ |subtract\ 2\ from\ both\ sides\\\\x=\dfrac{y^3}{2^3}-2\\\\x=\dfrac{1}{8}y^3-2\\\\\boxed{f(x)=2\sqrt[3]{x+2}\to f^{-1}(x)=\frac{1}{8}y^3-2}$
