First distribute
7x + 21 = 6 + 7x + 15

Cancel equal terms
7x + 21 = 21 + 7x
-7x -7x

Then you’ll get
21=21

So the statement is true

7(x + 3 ) = 6 - (-7x - 15)

Apply the distributive rule to remove parentheses.

7x + 21 = 6 + 7x + 15

Right away, you should be able to see that 7x will be cancelled rendering this equation to have no solution.

Answer:

Step-by-step explanation:

The supplementary angles to ∠x are adding to 180° and are ∠HGC and ∠BGA

If ∠DGE = 90° , then

∠CGD is also 90° because ∠DGE and ∠CGD are a linear pair and

∠HGC is also 90° because ∠DGE and ∠HGC are vertical angles

Jabari is power washing houses for a summer job. For every job, he charges an initial fee plus $30 for each hour of work. His to

guapka [62]

Answer: $f=30t+50$

Step-by-step explanation:

Given: Jabari's total fee, f, for a single job is a function of the number, t, of hours it takes him to complete the job.

For every job, he charges an initial fee plus $30 for each hour of work.

let m be his initial fee.

Then $f=30t+m$ .......(1)

Also, his total fee for a 4-hour job, for instance, is $170.

Put t=4 and f=170 in (1), we get

$170=30(4)+m\\\Rightarrow170=120=m\\\Rightarrow\ m=170-120\\\Rightarrow\ m=50$

Now, put m=50 in the (1), we get the function's formula for Jabari's total fee, f as

$f=30t+50$

Anni [7]

Answer:

The length of each side of the square is 5 meters

Step-by-step explanation:

<u><em>The correct question is</em></u>

A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?

we know that

The total area of the figure is equal to the area of triangle plus the area of square

The area of square is equal to the area f the figure minus the area of triangle

Let

A ----area of the square

$A=32.5-7.5=25\ m^2$

Find the length side of the square

Remember that the area of the square is

$A=b^2$

where

b is the length side of the square

substitute

$25=b^2$

square root both sides

$b=5\ m$

therefore

The length of each side of the square is 5 meters

Identify the oblique asymptote of f(x) =

Aleks04 [339]

The numerator is a degree of 2, higher than the denominator's degree of 1, so there is a oblique (slant) asymptote, which is the quotient.

use long division to find the quotient:
x +8
_____________________
x-2 I x² +6x -9
x² -2x
----------
8x -9

you don't have to finish, because the remainder doesn't matter. the answer is y=x+8
