Answer:

x-4 = 7 , x-4 = -7

Step-by-step explanation:

IX - 4l+ 1 = 8

Subtract 1 from each side

IX - 4l = 8-1

IX - 4l = 7

Then separate into two equations, one positive and one negative

x-4 = 7      x-4 = -7

x = 120

Answer:

The length of the window is 18 ft and its height is 14 ft

Step-by-step explanation:

System of Equations

Let's call:

L: Length of the window in feet

W: Width of the window in feet

According to the first condition of the problem:

[tex]L = W + 4\qquad\qquad [1][/tex]

The perimeter of the rectangle is 64 feet. The perimeter is calculated as:

P = 2L + 2W =64

Dividing by 2:

[tex]L + W = 32\qquad\qquad [2][/tex]

The system of equations [1] and [2] can be used to find the dimension of the window.

Substituting from [1]

W + 4 + W = 32

Simplifying:

2W = 32 - 4 =28

Solving:

W = 28/2 = 14

Using [1]:

L = 14 + 4 = 18

The length of the window is 18 ft and its height is 14 ft

dilation is the answer

Answer:

Step-by-step explanation:

(0, -9) and (3,3)

(3+9)/(3-0) = 12/3 = 4

y + 9 = 4(x - 0)

y + 9 = 4x - 0

y = 4x - 9

Answer:

5p + 42

Step-by-step explanation:

Step 1: Write expression

6(p + 6) - (p - 6)

Step 2: Distribute

6p + 36 - p + 6

Step 3: Combine like terms

5p + 42

Answer:

Step-by-step explanation:

Sum of angle in a triangle = 180°

<A+<B+<C = 180

Given <B = 50°

Substituting into the formula

<A+50+<C = 180

<A+<C = 180-50

<A+<C = 130°

Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°

The possible values of <A and <C that will be acute and give a sum of 130° are;

∠A= 58° and ∠C= 72°

∠A= 80° and ∠C= 50°

∠A= 60° and ∠C= 70°

You can see that all the Angles are less than 90° and their sum is 130°

Answer:

X=-2 (The slope is - 2/1)

Answer:

Below in bold

Step-by-step explanation:

-3(8x - 2) = 9 - 21x

~Divide -3 to everything

8x - 2 = -3 + 7x

~Add 3 to both sides

8x + 1 = 7x

~Subtract 8x to both sides

1 = -x

~Divide -1 to both sides

-1 = x

Note that this isn't the most used way to solve equations because you would typically use distribution to simplify the left side.

Best of Luck!

Answer: I believe it would be no solution

Step-by-step explanation

Answer:

No solutions

Step-by-step explanation:

y=7x+12;y=7x+2

Step: Solvey=7x+12for y:

y=7x+12

Step: Substitute7x+12foryiny=7x+2:

y=7x+2

7x+12=7x+2

7x+12+−7x=7x+2+−7x(Add -7x to both sides)

12=2

12+−12=2+−12(Add -12 to both sides)

0=−10

Answer:

I think its -2/3

Step-by-step explanation:

Step-by-step explanation:

For angle BDG

The common angles are: Angle DBG, Angle DGB

The common sides are: DG, GB, BD

And for angle AEF

The common angles are: Angle EFA, Angle EAF

The common sides are: EF, FA, AE

FOR the BGD triangle, all sides are connected together, so, all of them are common and the angles as well

And the same exact thing with triangle AEF also

Hope it helps!

Answer:

It would take 10 downloads

Step-by-step explanation:

Answer:

32 for Dominic and 5 for Savannah

Step-by-step explanation:

You can figure this out by first determining how many downloads Dominic has to make in order to have the total price equal to what Savannah paid just to join the club.

So Savannah paid $100 to join.  Dominic only paid $25.  So Dominic can spend $75 for downloads before he even gets up to what Savannah paid.  Now you can figure out that it will take 30 downloads at $2.50 each to get to that $75.  

You could say that Dominic is now equal to Savannah with both spending $100.  Dominic would have made 30 downloads and Savannah would have 0.  But I believe they want you to go a step further.

So now you just need to look at how many more downloads Dominic would have to make to get to an even full dollar amount.  One more download would take him up to $102.50.  A second additional download would take him to $105.  Savannah would then only have 5 downloads for a total cost of $105 and Dominic would now have a total of 32 downloads for a total of $105.

Answer:

x=2

Step-by-step explanation:

subtract 7/9x -4/9x

3/9x= 1/4 +5/12

first change 1/4 to 3/12

then add 3/12 + 5/12

3/9x = 8/12

change 3/9x to 1/3x then to 4/12x

4/12x = 8/12

then mulitiply by the reciprical 12/4 on both sides

x = 2
