Answer:
y=4x-8 hope this helps:)
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...

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

A square drawing for a triangular lot measures 6.8 cm by 12.3 cm. The scale is 5 cm: 25 m. Find the area of the parking lot.
5/25 = 6.8/x
5x = 170
x = 34
5/25 = 12.3/x
5x = 307.5
x = 61.5

The temperature at 6:00p.m. was 7 degrees Celsius. The temperature dropped 2 degrees every hour. What was the temperature at 11:00 p.m.
Answer:
7 Celsius to Fahrenheit is 44.6.
There is a five hour gap.
The tempature drops two degrees per hour. So, multiply.
2 x 5 = 10.
Subtract 10 from 44.6.
You get 34.6.
34.6 is the answer.
Point W is on line segment V X. Given W X = 2 and V X = 17, determine the
length VW.
Answer:
VW = 19 units
Step-by-step explanation:
Here, we are to determine the value of the length of VW

VW = VX + WX
VW = 17 + 2
VW = 19 units
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
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

Answer:
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
Order each set of cards from least to greatest. a. .,⎯⎯⎯⎯√,0.25 , comma , square root of 1 ninth end root , comma , 6 twenty fifths b. ⎯⎯⎯⎯⎯⎯⎯√,.,⎯⎯√square root of 121 over 25 end root , comma , 2.25 , comma square root of 5
Given:
a. [tex]\sqrt{0.25},\sqrt{\dfrac{1}{9}},\dfrac{6}{25}[/tex]
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].
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?
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

Place elementary school is raising money. they raise $90 a week. how long will it take to raise $900?
Answer: It will take 10 weeks! :)
Step-by-step explanation:
So let's look at this together.
The question states that they raise 90$ 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.

Answer:
B
Step-by-step explanation:
So, we have the expression:
[tex](3k-1)-(5k-4)[/tex]
First, distribute the negative on the right:
[tex]=3k-1-5k+4[/tex]
Combine like terms:
[tex]=(3k-5k)+(-1+4)[/tex]
Add:
[tex]=-2k+3[/tex]
So, our only correct answer is B.
The other answers can't be obtained.
And we're done!
