What is the equation of the line passing through the points (4,8) and (-1,-12)

Answers

Answer 1

Answer:

y=4x-8 hope this helps:)

Answer 2

Step-by-step explanation:

Hey there!!

You can find the equation of a st.line passing through points using one point formula if only one point is given and slope is given , else find it by using two point formula (if 2 points are given).

Here, the points are, (4,8) and (-1,-12).

Using two point formula,

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Keep all values,

[tex](y - 8) = \frac{ - 12 - 8}{ - 1 - 4} (x - 4)[/tex]

Now, simplify them.

[tex](y - 8) = 5(x - 4)[/tex]

y - 8 = 5x -20

5x -y -20+8 = 0

Therefore, 5x - y -12 = 0 is the required equation.

Hope it helps...

Place elementary school is raising money. they raise $90 a week. how long will it take to raise $900?

Answers

Answer: It will take 10 weeks! :)

Step-by-step explanation:

So let's look at this together.

The question states that they raise 90$ per week.

There's two ways you can do this

You can multiply,

Think, what times 90 will equal 900? The answer is 10!

90 x 10= 900!

(if you need help with multiplication, let me know)

Or you can divide.

900/90=10!

(if you need help with division, let me know)

So it would take, in total, 10 weeks to raise 900 dollars.

find the values of x and y (2y+5) + (5x-17) +( 3x-11)

Answers

Step-by-step explanation:

Hey there!!

You can simply work with it.

(5x - 17)° + (3x - 11)° = 180° { Being a linear pair}.

or, 8x - 28°= 180°

8x = 180° + 28°

[tex]x = \frac{208}{8} [/tex]

Therefore, the value of x is 26°.

Now,

3x - 11°= 3×26°-11° = 67°

Again,

67°+90°+(2y+5)° = 180° { being linear pair}.

157°+2y+5° = 180°

or, 2y + 162° = 180°

or, 2y = 180° - 162°

[tex]y = \frac{18}{2} [/tex]

Therefore, the value of y is 9°.

The value of x is 26° and y is 9°.

b. [tex]\sqrt{\dfrac{121}{25}},2.25,\sqrt{5}[/tex]

To find:

The correct order for each set of cards from least to greatest.

Solution:

a. [tex]\sqrt{0.25},\sqrt{\dfrac{1}{9}},\dfrac{6}{25}[/tex]

Convert all numbers in decimal form.

[tex]\sqrt{0.25}=0.5[/tex]

[tex]\sqrt{\dfrac{1}{9}}=\dfrac{1}{3}=0.333...[/tex]

[tex]\dfrac{6}{25}=0.24[/tex]

It is clear that,

[tex]0.24<0.33...<0.5[/tex]

[tex]\dfrac{6}{25}<\sqrt{\dfrac{1}{9}}<\sqrt{0.25}[/tex]

Therefore, the required order is [tex]\dfrac{6}{25},\sqrt{\dfrac{1}{9}},\sqrt{0.25}[/tex].

b. [tex]\sqrt{\dfrac{121}{25}},2.25,\sqrt{5}[/tex]

Convert all numbers in decimal form.

[tex]\sqrt{\dfrac{121}{25}}=\dfrac{11}{5}=2.2[/tex]

[tex]2.25[/tex] already in decimal form.

[tex]\sqrt{5}\approx 2.236[/tex]

It is clear that,

[tex]2.2<2.236<2.25[/tex]

[tex]\sqrt{\dfrac{121}{25}}<\sqrt{5}<2.25[/tex]

Therefore, the required order is [tex]\sqrt{\dfrac{121}{25}},\sqrt{5},2.25[/tex].

Kai is making a chessboard using pieces of wood that measure 1sq in when she finishes the chessboard well have an area of 64 sq in how many pieces of wood should he put along each side

Answers

Answer:

8 pieces of wood should be put along each side of the chessboard

Step-by-step explanation:

Here in this question, we are interested in knowing the the number of pieces of wood that should be put along each side of the cheese board.

Firstly, to know the number of pieces of wood to use, we need to divide the area of the board by the area of each piece of wood

Mathematically that would be 64 square inches/ 1 square inch = 64 pieces of wood

64 pieces of wood would be needed to complete the cheeseboard.

The number of pieces to put along each side of the cheese board will be √64.

This is because the shape of a chessboard is square.

Thus the number of pieces to put on each side will be √64 = 8

x = 9

Step-by-step explanation:

Simplifying

-4 = 5 + -1x

Solving

-4 = 5 + -1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.

-4 + x = 5 + -1x + x

Combine like terms: -1x + x = 0

-4 + x = 5 + 0

-4 + x = 5

Add '4' to each side of the equation.

-4 + 4 + x = 5 + 4

Combine like terms: -4 + 4 = 0

0 + x = 5 + 4

x = 5 + 4

Combine like terms: 5 + 4 = 9

x = 9

Simplifying

x = 9

Answer: The answer is x=9

Step-by-step explanation: Good afternoon, I got a different step-by-step explanation for you!!! :D Step 1: Simplify both sides of the equation: [tex]-4=5-x[/tex], [tex]-4=5+-x[/tex], and [tex]-4=-x+5[/tex]. Step 2. I flipped the equation: [tex]-x+5=-4[/tex].

Step 3. Subtract 5 from the both sides: [tex]-x+5-5=-4-5[/tex] to [tex]-x=-9[/tex].

Last but not least is step 4. Divide the both sides by –1: [tex]\frac{-x}{-1}=\frac{-9}{-1}[/tex]; ∴, your answer should be x=9, I hoped your answer is very helpful, please mark me as brainliest, and have a happy holidays!! :D

Paul took 6 blocks and arranged them in a pile. If each block is 4 inches in height. How many feet high is the pile that Paul made?

Answers

6x4 is 24, 24 inches to ft is 2 ft, since 12in is 1ft.

Answer:

The pile is 2 feet high.

Step-by-step explanation:

There are 6 blocks, each block is 4 inches in height. That means the total height is:

6×4=24 inches

Because the question asked for the answer in feet, you have to convert the 24 inches into feet:

24 inches=2 feet

Answers

Answer A: 100 Deg.

Explanation:

Because angle ADC is 40 degrees, angle CAD is also 40 degrees. This is because lines CD and CA are the same length.

Angle CAD is equal to Angle BCA because they are vertical angles. This makes angle BCA 40 degrees.

Angle BAC is equal to BCA because the lines BA and BC are equal. This makes angle BAC 40 degrees.

You now know 2 angles of the triangle ABC. Knowing that all angles in a triangle add up to 180 degrees, subtract the other two angles to get angle ABC. 180-(40+40)= 100. This makes angle ABC equal 100 degrees
