2a + 2b = c

Subtract 2a from both sides

2b = -2a + c

Divide both sides by 2

b = -a + (c/2)

if you horizontally shift the square root parent function, F(x) = <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormu
Juli2301 [7.4K]

ANSWER

g(x) =  \sqrt{x + 4}

EXPLANATION

The parent square root function is

f(x) =  \sqrt{x}

The translation

g(x ) =  \sqrt{x + k}

Will shift the graph of f(x) k units to left.

The translation

g(x) =  \sqrt{x -k}

will shift the graph of f(x) to the right by k units.

Therefore if f(x) is shifted 4 units to the left its new equation is:

g(x) =  \sqrt{x + 4}

A car purchased in 2014 was worth $21,000. It has depreciated at an annual rate of 8.5%. what will its value be in 2021?
liraira [26]

Answer: The value of the car in 2021 will be $11,276.31.

Step-by-step explanation:

If r is the depreciation rate and P is the initiial amount , then the amount after t years is given by:-

A=P(1-\dfrac{r}{100})^t

Given: P=21000, r=8.5%  , t= 2021-2014= 7

Plug all the values in the formula, we get

A= 21000(1-\dfrac{8.5}{100})^7\\\\\Rightarrow\ A=21000(1-0.085)^7\\\\\Rightarrow\ A= 21000(0.915)^7\\\\\Rightarrow\ A= 21000(0.5369670)\approx11276.31

The value of the car in 2021 will be $11,276.31.

Given the scatter plot, choose the function that best fits the data.
igor_vitrenko [27]

Answer:

f(x) = 3x2

Step-by-step explanation:

I think the given the scatter plot is missing and it is my attachment for your question.

My answer:

f(x) = 3x2,  it is a parabolic pathway. a =3 (positive) so the line is going up.

The other options are straight lines so they are wrong.
