Answer:

x<3

Step-by-step explanation:

Let us move all the x values to one side and the numerical values to the other:

1>2x+2x-11

1+11>2x+2x

12>4x

3>x or x<3

I hope this helps! :)

Use the graph shown to evaluate the composition (f○g)(0)

andrey2020 [161]

Function composition is applying one function to the results of another:

$\rightarrow g(x)\rightarrow f(x)\rightarrow$

This means the result of g() is sent through f(). Written notation for the composition is

$(f\circ g)(x)=f(g(x)).$

Note that $g(0)=2,$ then

$(f\circ g)(0)=f(g(0))=f(2).$

Since $f(2)=3,$ then

$(f\circ g)(0)=f(2)=3.$

Answer: $(f\circ g)(0)=3.$

What is the value of the variable in the equation, r-17=22 *

aleksklad [387]

Answer:

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7, or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

Answer: x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

Factor the common factor out of 8^3 + 12x

strojnjashka [21]

The factorized expression of 8^3 + 12x is 4(128+ 3x)

<h3>How to factor the common factor out?</h3>

The expression is given as:

8^3 + 12x

Evaluate 8^3

8^3 + 12x = 512 + 12x

Factor out 2 from the expression

8^3 + 12x = 2(256+ 6x)

Factor out 2 from the expression

8^3 + 12x = 2 * 2(128+ 3x)

Evaluate the product

8^3 + 12x = 4(128+ 3x)

Hence, the factorized expression of 8^3 + 12x is 4(128+ 3x)

Jocelyn invested $390 in an account paying an interest rate of 2.7%

Katarina [22]

Answer:

There will be $634.05 in the account.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$390 in an account paying an interest rate of 2.7% compounded daily.

This means that $P = 390, r = 0.027, n = 365$

Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 18 years?

This is A(18). So

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(18) = 390(1 + \frac{0.027}{365})^{365*18}$

$A(18) = 634.05$

There will be $634.05 in the account.

Find the solution set (x,y,z) of the system: 3x-2y+4z=6 2y-3z=20 6z=12

gizmo_the_mogwai [7]

Answer:

The solution is x = 8, y = 13 and z = 2.

Step-by-step explanation:

We are given a system of equations with the variables x, y, and z from which we have to solve for x, y, and z.

The equations are

3x - 2y + 4z = 6 ........ (1)

2y - 3z = 20 .......... (2)

6z = 12 ......... (3)

Now, from equation (3), we get z = 2.

Now, putting z = 2 in equation (2) we get

2y = 20 + 6 = 26

⇒ y = 13

Now, from equation (1), putting y = 13 and z = 2, we get

3x = 6 - (4 × 2) + (2 × 13) = 24

⇒ x = 8

So the solution is x = 8, y = 13 and z = 2. (Answer)
