Answer:

x = - 2√2

x = -2

Step-by-step explanation:

A . 5 + x² = 2 x² +13

    5 + x² - 2 x² - 13 = 0

      - x² -8 = 0

      - x² = 8

         x² = -8

         x = - √8

          x = - 2√2

B . 5 + x³ = 2 x³ + 13

    5 + x³- 2 x³ - 13 = 0

       - x³ -8 = 0

        -x³ = 8

         x³ = -8

      x = - ∛8

         x = -2

Answer:

y = -7

Step-by-step explanation:

To answer this question, we must first plug in -8 for x:

3(-8) + 5y = -59

-24 + 5y = -59

+24           +24

5y = -35

/5      /5

y = -7

Hope this helps :)

im dumb and answered wrong...

the answer above is right ✅

Numbers are 36, 22

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in mathematics when you do not know the exact number in a calculation.

Given

One number is 14 more than another and their sum is 58.

Let one number be x

Another number will be x + 14

Rewriting the equation in mathematical form

⇒ [tex]n+ (n+4) =58[/tex]

⇒ [tex]2n +14 =58[/tex]

⇒ [tex]2n = 58-14[/tex]

⇒ [tex]2n=44[/tex]

⇒ [tex]n= \frac{44}{2}[/tex]

⇒ [tex]n=22[/tex]

⇒ [tex]n+14=22+14=36[/tex]

Hence, numbers are 36, 22

Step-by-step explanation:

m+7−5=20

Step 1: Simplify both sides of the equation.

m+7−5=20

m+7+−5=20

(m)+(7+−5)=20(Combine Like Terms)

m+2=20

m+2=20

Step 2: Subtract 2 from both sides.

m+2−2=20−2

m=18

Answer:

m=18

Answer:

the correct answer is (x,y) (3,-2)

The degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that:

The measuring unit is the degree

The measurement can be defined as the numerical quantity that gives an idea about object length, width, and many more. It can be used to compare two objects.

As we know from the definition of the angle; two lines or rays converge at the same point, and the measurement between them is called an "Angle."

The degree measures an angle which is the measure of incline.

Thus, the degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

Answer:

Step-by-step explanation:

If they want the average for four months to be 55 minutes, this means that the total of the four months = 55 x 4

Total of four months = 220 minutes

They already told us that the three previous months she used her cellphone for 43 minutes, 62 minutes and 57 minutes.

All you have to do now is subtract everything from the total of the four months.

4th month = 220 - 43 - 62 - 57

= ? Minutes

Answer:

Sure thing!

For the first equation 6v+38≤ -4

The answer would be v≤-7

and for the second equation 2(v+3)≥-2

the answer would be v≥-4

Step-by-step explanation:

6v+38≤ -4

Subtract 38 from both sides

6v+38-38≤-4-38

Simplify

6v≤-42

Divide both sides by 6

6v/6≤-42/6

Simplify

v≤-7

SAME THING FOR THE OTHER

2(v+3)≥-2

Divide both sides by 2

2(v+3)/2≥-2/2

Simplify

v+3≥-1

Subtract 3 from both sides

v+3-3≥-1-3

And finally, simplify

v≥-4

Step-by-step explanation:

it's basically how far is it from 0 sooo

Answer:

6

Step-by-step explanation:

Positive 6 is six away from 0, therefore the answer is 6.

Step-by-step explanation:

2(9n-1)+7(n+6)=-60

18n - 9 + 7n + 42 = -60

25n + 33 = -60

25n = -93

n = -3.72

11(4-6y)+5(13y+1)=9

44 - 66y + 65y + 5 = 9

-y + 49 = 9

-y = -40

y = 40

Answer:

Hello! I hope I’m correct!! :)

1. n = -4

2. y = 40

Step-by-step explanation:

Steps for the first equation.

Step #1. {we are solving for “2(9n-1)+7(n+6)=-60”}

[tex]18n-2+7n+42=-60[/tex]

Step #2. Simplify.

[tex]25n+40=-60[/tex]

Step #3. Subtract 40 {from both sides}

[tex]25n=-60-40[/tex]

Step #4. Simplify.

[tex]25n=-100[/tex]

Step #5. Divide both of the sides by 25. Which will be:

[tex]-\frac{100}{25}[/tex]

Step #6. Now divide (simplify) 100 & 25 which will give you the answer.

[tex]n=-4[/tex]

______________________________________

Now let’s solve the second equation.

Step #1. Expand

[tex]-y+49=9[/tex]

Step #2. Subtract 49 from both sides.

[tex]-y+49-49=9-49[/tex]

Step #3. Simplify.

[tex]-y=-40[/tex]

Step #4. Divide both sides by -1.

[tex]-40/-1[/tex]

Step #5. Simplify.

[tex]y=40[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

12 - ( 4 x 2 +2 ) + 3 x 5 =17

Answer:

Attached image

Step-by-step explanation:

The first step is to line it up in the Pythagorean theorem, then you want to move the [tex]6^{2}[/tex] to the other side of the equation via subtraction from both sides in order to isolate the [tex]x^2[/tex]. After that, you'll end up with [tex]x^{2} =64[/tex] then you'll want to square root both sides and end with [tex]x=8[/tex].

The answer is [tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]

First, you must flip the equation

[tex]12k+29[/tex] ≥ [tex]120[/tex]

Then, you must subtract 29 on both sides

[tex]12k[/tex] ≥ [tex]91[/tex]

Finally, divide both sides by 12

[tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]
