Help me with this please I’d appreciate it

Answer:

Each term is 2 greater than the term before it. Thus for any given term, an, our equation is:

an=2n

We can write this in a form closer to standard, by noting that a1=2, so we can make it dependent on a1..

an=a1+2(n−1)=2+2(n−1)

Answer:

$15.67

Step-by-step explanation:

first add $14.16 and $10.17 Wich equals $24.33 and then add your 2 twenty's Wich is 40 so then you subtract $40.00- $24.33.

Hello :D

2 x $20 = $40

$10.17 + $14.16 = $24.33

$40 - $24.33 = $15.67

The answer is $15.67. I hope this helps

Using pythagorean theorem

[tex]\\ \sf\longmapsto x^2=11^2+11^2[/tex]

[tex]\\ \sf\longmapsto x^2=121+121[/tex]

[tex]\\ \sf\longmapsto x^2=242[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{242}[/tex]

[tex]\\ \sf\longmapsto x=15.4[/tex]

Step-by-step explanation:

Use the pythagorean theorem

[tex]a {}^{2} + b {}^{2} = c {}^{2} [/tex]

[tex]11 {}^{2} + 11 {}^{2} = c {}^{2} [/tex]

[tex]121 + 121 = c {}^{2} [/tex]

[tex]c = \sqrt{242} = 2 \sqrt{11} [/tex]

Answer:

$7,000 at 7%; $13,000 at 8%

Step-by-step explanation

x: the amount invested at 7%

y: the amount invested at 8%

x + y = 20,000

7%.x + 8%.y = 1,530

⇒ x =7,000

y = 13,000

Answer:

Step-by-step explanation:

The equation has to be

8x + 20 = 148                  Subtract 20 from both sides

8x = 148 - 20                  Combine

8x = 128                          Divide by 8

x = 128/8                        

x = 16

Answer:

x 2 + 5 x + 6

Step-by-step explanation:

y = m x + c

y- intercept

x = 0

y = (-2) (0) + 3

=3

(x =0,  y = 3)

-8 < 2x-4 < 8

Add 4 to all sides:

-8 + 4 < 2x -4 + 4 < 8 + 4

Simplify :

-4 < 2x < 12

Divide all sides by 2:

-4/2 < 2x/2 < 12/2

Simplify to get the answer:

-2 < x < 6

Answer:

x = 7

Step-by-step explanation:

8(5x + 2) = 296

40x + 16 = 296

40x = 280

x = 7

Answer:

x=7

Step-by-step explanation:

➼Okay, so first thing you need to do is to distribute the 8 to everything in the parentheses:

8(5x+ 2) = 296

8 times 5x

8 times 2

(8 x 5x) + (8 x 2) = 40x + 16

➼Now you solve for x

40x+16=296

➼to get rid of 40 you have to do the opposite and divide it by everything

40x+16=296

40/40=0

16/40=0.4

296/40=7.4

➼all adds up to x + .4 = 7.4 but to get the x alone you need to get rid of the .4, we'll do this by doing the opposite and subtract it from everything

.4-.4=0

7.4-.4=7

➼so in conclusion

x=7

Answer:

The statement is not correct.

Simply subtracting the [tex]$y$[/tex]-coordinate does not ensure that we will have a nonnegative result.

Step-by-step explanation:

Given

To find the length of a segment than the Distance Formula when the x-coordinates of the endpoints are equal. He claims all you have to do is subtract the y-coordinates.

Step 1 of 2

Your friend is not correct.

We shall take note that distances are nonnegative.

Simply subtracting the [tex]$y$[/tex]-coordinate does not ensure that we will have a nonnegative result.

Step 2 of 2

[tex]A B &=\sqrt{\left(x_{1}-x_{2}\right)^{2}+\left(y_{1}-y_{2}\right)^{2}} \\[/tex]

[tex]&=\sqrt{(x-x)^{2}+\left(y_{1}-y_{2}\right)^{2}} \\[/tex]

[tex]&=\sqrt{0+\left(y_{1}-y_{2}\right)^{2}} \\[/tex]

[tex]&=\sqrt{\left(y_{1}-y_{2}\right)^{2}} \\[/tex]

[tex]A B &=\left|y_{1}-y_{2}\right|[/tex]

Therefore, if the [tex]$x$[/tex]-coordinate of the endpoints are the same, then we can proceed by taking the absolute value of the difference of the [tex]$y$[/tex]-coordinates to find the length of the segment.

-|3x-9|+2=-4

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

-|3x-9|+2 = -4

Another term is moved / added to the right hand side.

To make the absolute value term positive, both sides are multiplied by (-1).

|3x-9| = 6

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |3x-9|

For the Negative case we'll use -(3x-9)

For the Positive case we'll use (3x-9)

STEP

3

:

Solve the Negative Case

-(3x-9) = 6

Multiply

-3x+9 = 6

Rearrange and Add up

-3x = -3

Divide both sides by 3

-x = -1

Multiply both sides by (-1)

x = 1

Answer: x= 1, 5

Step-by-step explanation:

First, isolate the absolute value. Subtract two from the equation to get -l3x-9l=-6, and then divide by -1 to get l3x-9l=6.

Since an absolute value measures how far away a value is from zero, it's always positive. For example, -10 and 10 have the same absolute value, 10, because they're both 10 units away from zero.

Because of this, you create two equations; 3x-9=6, and 3x-9=-6.

For the first equation, add 9 to 6 and divide that by 3 to get x=5.

For the second equation, add 9 to -6 and divide that by 5 to get x=1.
