What is an equation of the line that is parallel to y = 9- 4x and passes through (0, 7)​

Answers

Answer:

y = -4x + 7

Step-by-step explanation:

Since they are parallel they must have the same gradient which is -4

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

m = -4

x = 0

y = 7

7 = -4 × 0 + c

c = 7

[tex]y = - 4x + 7[/tex]

Answers

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. 5p+ 30
Explanation. 6(p+6) - (p-6)
We must expand.
6 times p is 6p+ 6 times 6 which is 36.
You now have:
6p+ 36 - p- 6
Combine like terms: 6p- p + 36- 6 Your final answer is:
5p+ 30

Step-by-step explanation:

Each sheep has 4 legs and each chicken has 2 legs. If a farm boy counts 50 heads and 140 feet, how many sheep are there?

1. 30 sheep
2. 20 sheep
3. 10 sheep

Answers

Answer:

20

Step-by-step explanation:

H+S=50

2H+4S=140

4H+4S=200

4H+4S=200-

2H+ 4S =140

2H=60

H=30

50-30=20

Given:

Each sheep has 4 legs and a chicken has 2 legs.

A farm boy counts total heads = 50

And number of legs = 140

To Find:

Number of sheep.

Solution:

Let the number of sheep in the farm = s

And the number of chicken in the farm = h

If the total number of heads = 50

s + h = 50 ------- (1)

If the total number of the legs = 140

Number of legs of 's' sheep = 4s

Number of legs of 'h' chicken = 2h

Therefore, 4s + 2h = 140

2s + h = 70 -------(2)

Subtract equation (1) from equation (2),

(2s + h) - (s + h) = 70 - 50

s = 20

Therefore, 20 sheep are in the farm.

In triangle ABC, the measure of angle B is 50 degrees. Select all possible values for the measures of A and C if ABC is an acute triangle. m\angle∠A= 58 degrees; m\angle∠C= 72 degrees m\angle∠A= 100 degrees; m\angle∠C= 30 degrees m\angle∠A= 80 degrees; m\angle∠C= 50 degrees m\angle∠A= 60 degrees; m\angle∠C= 70 degrees m\angle∠A= 90 degrees; m\angle∠C= 40 degrees m\angle∠A= 105 degrees; m\angle∠C= 25 degrees

Answers

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°

Savannah paid $100 to join a music club. She then pays $1.00 per music download. Dominic joined a club for $25 but pays $2.50 per download. Determine the
number of downloads when the cost will be the same

Answers

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.

The length of a rectangular window is 4 more feet than its width w. The perimeter of the window is 64 feet. Write an equation that could be used to find the demensions of the window and determine the length and width of the window.

Answers

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

Answers

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!
