et f(x) = x + |2x − 3|. Find all solutions to the equation f(x) = 12. (Enter your answers as a comma-separated list. If an answe
Alinara [238K]

Answer:

1. {5,-9}

2.{4}

3.{9/2}

Step-by-step explanation:

The equation f(x)=x+\lvert 2x-3 \rvert=12 can be solved as follows:

x+\lvert 2x-3 \rvert =12\,\,\,\text{(given equation)}

\lvert 2x-3 \rvert =12-x

2x-3=12-x\,\,\text{or}\,\,2x-3=-(12-x)

3x=15\,\,\text{or}\,\,\x=-9

Then, the solutions of the equation are x=5, x=-9.

Now, if g(x)=5x-3+\lvert x+4\rvert, we can solve the equation g(a)=4a+9 as follows:

5a-3+\lvert a+4 \rvert =4a+9

\lvert a+4\rvert =4a+9-5a+3

a+4 =-a+12\,\,\text{or}\,\,a+4=-(-a+12)

2a=8\,\,\text{or}\,\,4=12

So, the unique solution of this last equation is a=4

The last equation is h(x-1)=x-3, where h(x)=\lvert x \rvert -2x+5.. To solve this equation we can proceed as follows:

h(x-1)=x-3

\lvert x-1\rvert -2(x-1)+5=x-3

\lvert x-1 \rvert -2x+2+5=x-3

\lvert x-1\rvert =3x-10

x-1=3x-10\,\,\text{or}\,\,x-1=-(3x-10)

-2x=-9\,\,\text{or}\,\,4x=11

x=9/2\,\,\text{or}\,\,x=11/4

But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.

Help asap Which explains how to find the quotient of the division below? -3 1/3 divided by 4/9
noname [10]

Answer:

-7\frac{1}{2}

Step-by-step explanation:

To find the quotient, convert the mixed number to an improper fraction first

-3\frac{1}{3}=-\frac{3*3+1}{3}=-\frac{10}{3}

Find the quotient now

\frac{(-10/3)}{(4/9)}=-\frac{10*9}{4*3}\\ \\=-\frac{90}{12}

Simplify

Divide by 6 both numerator and denominator

=-\frac{15}{2}=-7.5

Convert to a mixed number

-7.5=-(7+0.5)=-(7+\frac{1}{2})=-7 \frac{1}{2}

13. Xavier spent $84 on art supplies. The canvas for each of his paintings is an additional $1. He
sergeinik [125]

Answer: 84 = 8p - 1 (or $84 = $8p - $1, but it is usually put together like the first equation)

Step-by-step explanation: $84 is the break even point, so the equation must be able to come out to at least $84 if it is correct.

$84 in equation is break even

8p/$8p is the price per painting

-1/-$1 is the addition from the canvas

How do you write the equation in point slope form given slope=8, passing through (4,-1)?
xxMikexx [17]

Point slope form, y-y1 = m(x-x1)

Here, y1 = -1, x1 = 4, m=8

so, it would be: (y+1) = 8(x-4)
