4(2x+1)-(-2+8x) : use the distributive property and combining like terms to simplify

i think it is -25x + 24y +6, if you're multiplying the variable, but if you're adding them then it is x - 10y +6

Answer:

(-2,1)

Step-by-step explanation:

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(1, 2) and B(7, 8)

The midpoint is

[tex]M = ( \frac{1 + 7}{2} , \: \frac{2 + 8}{2} ) \\ = ( \frac{8}{2} \: , \: \frac{10}{2} )[/tex]

We have the final answer as

Answer:

-4

Step-by-step explanation:

The equation is conveniently in slope-intercept form.

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The '-4' is in place of 'm' in the equation. This means that -4 is the slope of the line.

[tex]y=\boxed{m}x+b\rightarrow y=\boxed{-4}x+b[/tex]

Hope this helps.

Answer:

-16.5

Step-by-step explanation:

1) -5*3.3

2) (Multiplying with 1 negative number makes it negative)

3) -16.5

Answer:

14.14 inches

Step-by-step explanation:

We know that the diagonal of a square is [tex]\sqrt{2}a[/tex], where a is the length of the side.

The diagonal of a square is the hypotenuse of this triangle.

That means the hypotenuse will be equal to [tex]\sqrt{2}\cdot10[/tex]

This can be simplified to [tex]\sqrt{200}[/tex], which, rounded to the nearest hundredth is 14.14.

Hope this helped!

Answer:

yes, -6/-3=2

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

The indicated angles are vertical and congruent, thus

14x + 2 = 13x + 9 ( subtract 13x from both sides )

x + 2 = 9 ( subtract 2 from both sides )

x = 7

HOPE THIS IS THEANSWER YOU NEEDED

Answer:

x=3

Step-by-step explanation:

4−2x=−2

Step 1: Simplify both sides of the equation.

4−2x=−2

4+−2x=−2

−2x+4=−2

Step 2: Subtract 4 from both sides.

−2x+4−4=−2−4

−2x=−6

Step 3: Divide both sides by -2.

-2x/-2=-6/-2

X=3

Answer:

67.00

Step-by-step explanation:

Add the numbers.

You get 67.08.

You want it rounded.

So now the answer is 67.00.

Answer:

the perpendicular slope would be 2

Step-by-step explanation:

x+2y=5

2y=5-x

y=(5-x)/2

the slope of the original equation is -1/2

so you would then flip it and multiply by -1.

-1/2 -> -2*-1 -> 2

Step-by-step explanation:

Answer:

The y coordinate is 3

Step-by-step explanation:

Here, we want to find the y-coordinate of the line that divides the line segment in the given ratio.

To calculate this, we shall be using the internal division formula;

It is as follows;

( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))

In this question;

m = 3 and n = 4

x1 = 0 , y1 = 6

x2 = -10, y2 = -1

Now substituting these values into the equation, we have;

(3(-10) + 4(0)/(3 + 4) , (3(-1) + 4(6)/(3+4))

= -30/7 , (-3 + 24)/7

= -30/7 , 21/7

= -30/7 , 3

Answer:

Step-by-step explanation:

2y+6+y+8=20

3y+14=20

3y=6

y=2

Answer: x = 35

Explanation: In this problem, notice that D is being divided by 5,

so to get D by itself, we need to multiply both sides of the equation by 5.

Notice that on the left side, the 5 and 5 cancel

each other out, so we are just left with D.

On the right side, we have (7)(5) which is 35.

So x = 35.

Finally, remember that we can check our answer

by plugging a 35 back into the original equation.

So we have [tex]\frac{(35)}{5} = 7[/tex].

Since this is a true statement, we know that our answer is correct, x = 35.

Answer:

RU is 8

Step-by-step explanation:

The change in Nina'a account balance is -$160.

Nina made 8 withdrawals and each time she took $20.

The change in her account balance will therefore be whatever the account balance is less the amount that she withdrew.

The total amount of money she withdrew is:

= Number of withdrawals x Amount withdrawn each time

= 20 x 8

= $160

Her account is therefore lower by $160.

In conclusion, the change in her account balance is -$160.
