Please help solve this and show work 4(x+1)-9=11

Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

Given

4(x + 1) - 9 = 11 ( add 9 to both sides )

4(x + 1) = 20 ( divide both sides by 4 )

x + 1 = 5 ( subtract 1 from both sides )

x = 4

Answer 2

Answer:

Step-by-step explanation:

4x + 4-9=11

4x  -5  =11

4x -5+5 =11+5

       4x =16

       4x divide by 4 is equal to 16 divide by 4

x is equal to 4

If T is the midpoint of SU, what are ST, TU, and SU.
*Question 16*

Answers

We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:

5x = 3x + 32

2x = 32

x = 16

ST = 5x = 80

So TU = 80 and SU=160

Answers

Answer:29° because the angle in between x and 105 is 54(alternate angles) in theory angles on a straight line add upto 180° so therefore x+105+54=180 thus x+159=180 as a result the remaining angle (x) would be 180-159=29° therefore x=29°

Write the domain and the range of the function as an inequality, using set notations, and using interval notation. Also describe the end behavior of the function or explain why there is no end behavior (19 points and brainliest)

Answers

Answer:

Step-by-step explanation:

I think we need to define domain and range first.

Domain is the set of all x values where the function f(x) exists or is defined.

Range is the set of all y values that will result from substituting all x values (the domain) into the function.

So for g(x) = 2x - 2 we can evaluate g(x) at any point, and we will get a real answer for y.

So the range of g(x) = 2x -2 is also all real numbers, because no matter what value of x is, we can always multiply that number by 2 and subtract 2.

The inequality does not affect the domain and range of linear functions at all. Don't confuse domain and range with a solution to an inequality. These two concepts are different. Domain and range mean all possible values of x and y that could be substituted into the inequality. A solution means all possible values that make the inequality statement true.

The domain as an inequality would be -∞ < x < ∞

The range as an inequality would be -∞ < y < ∞

As a set notation:

Domain {x | -∞ < x < ∞}

Range {y | -∞ < x < ∞}

In interval notation:

Domain (-∞ , ∞)

Range (-∞ , ∞)

End behavior:

As x gets larger and larger, g(x) gets larger and larger as well, and as x gets smaller, g(x) gets smaller too.

If:
AB = 62 – 7 and
BC = 5x - 3
Find AC

Answers

Answer:

            AC = 110    

Step-by-step explanation:

B being the midpoint of AC means:

AB = BC = 0.5AC  

AB = 0.5AC  ⇒  AC = 2AB

AC = 2(62 - 7) = 2×55 = 110

Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob’s checking account?

Answers

Answer:

$702.53

Step-by-step explanation:

178.74

36,52+18.92+25.93=81.37

178.74-81.37=97.37

300+100+205.16=605.16

605.16+97.37=702.53

The final balance is 702.53 dollars.

Answers

Answer:

4 more times

Step-by-step explanation:

The question says that easton paid 68 dollars for the interlocking set

Colin paid 17 dollars for his own.

We are required to find how many more times easton paid than colin

To do this we divide 68dollars by 17 dollars

68/17

= 4 times

This tells us that compared to colin, easton overpaid for his own set by 4times. Easton paid 4 more times than colin

Then move the value to one side, so add 9 to both sides.

4y-9+9=27+9

4y=36

Then divide 36 by 4
