Answer:
y = -5x + 29
Step-by-step explanation:
Slope-Intercept Form of the Line
Given a line of slope m and y-intercept b, the equation of the line can be written as:
y = mx + b
The slope can be calculated by using the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x1,y1) and (x2,y2) are the points through which the line passes.
We are given the points (5,4) and (6,-1), thus:
[tex]\displaystyle m=\frac{-1-4}{6-5}=\frac{-5}{1}=-5[/tex]
Now we use one of the points to find the value of b, for example (5,4):
4 = -5(5) + b
b = 25+4 = 29
Thus, the equation of the line is:
y = -5x + 29

The amount of water displacement would be equivalent to the volume of the rock, which is 1800. We find this by doing 10 x 12 which is 120. Now we can divide 1800 by 120, which is 15. Giving us the dimensions 10 x 12 x 15.

The diameter of a circle is 9 feet. Find the radius.
Answer:
4.5
Step-by-step explanation:
Diameter is equal to 2r. In other words, to find radius from the diameter, you divide the diameter by two. In this case, its 9/2. That gives you 4.5
Answer:
4 1/2 feet
Step-by-step explanation:
The radius fo the circle is half of the diameter so 4 1/2 Feet.

someone please do this and explain in detail of how you get x.
Answer:
x=8
AC=148
Step-by-step explanation:
Okay so if B is the midpoint of AC, that basically means that it's the halfway point. If B is exactly halfway between A and C, that means that the distance between A and B, and the distance between B and C is the same. In other words: AB=BC
Knowing that AB=BC, we can sub the values given by the question:
AB = BC
9x+2 = 5x+34
9x-5x = 34-2
4x = 32
x = 8
Now that we know the value of x, we can find AC, since AC=AB+BC
AC = AB + BC
= 9x+2 + 5x+34
= 14x+36
= 14(8)+36
=112+36
=148
Mr. Jones charged Roberta $32 for parts and $15 per hour for labor to repair her bicycle. He spent 3 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
Answer:
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Step-by-step explanation:
Given that:
Amount charged for parts = $32
Per hour labor = $15
Time spent on repairing = 3 hours
Total amount = Per hour labor * Number of hours + Amount of parts
T = 15*3 + 32
Hence,
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones

Suppose that a bike for $12 plus $ 1.60 per hour. What is the slope ?
Answer:
Slope = 1.60
Step-by-step explanation:
y = 1.60x + 12
$12 - This would be the y-intercept
$1.60 - slope since it is the amount needed to pay each hour.

A new factory is growing fast and hiring a lot of new workers. Every week, the total number of workers doubles in size. If it takes 18 weeks for the factory to be at full capacity, how many weeks would it take for the factory to be at half capacity?
Answer:
9 weeks
Step-by-step explanation:
divide the full capacity by 2 to get 9 because 9 x 2 is 18 and half of the full capacity would be half capacity

The length of a rectangle is
2
meters less than
3
times the width. The perimeter is
44
meters. Find the width.
Answer:
They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,
Step-by-step explanation:
Width : x
Length : x-44 (from the 1st sentence of question)
So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,
2(x)+2(x-44)=150150
2x+2x-88=150150
4x-88= 150150
4x= 150150+88=150238
4x=150238
x= 150238÷4
=37559.5
Answer:
The width is 8 meters and the length is 3(8)-2=22 meters. Hope this helps (owo)/ brainlist please.
Step-by-step explanation:
Let x= the width
then 3x-2= length (because the length is 2 meters less than 3 times the width)
P=2l+2w
60=2(lenght)+2(width)
60=2(3x-2)+2x
60=6x-4+2x Distribute
60=8x-4 Combine like terms
64=8x Divide both sides by 8
8=x

Find the value of x if A, B, and C are collinear points and B is between A and C. AB=6x,BC=x−5,AC=23
Answer:
The value of x = 4 if A, B, and C are collinear points and B is between A and C.
Step-by-step explanation:
We need to find the value of x if A, B, and C are collinear points and B is between A and C.
We have AB=6x,BC=x−5,AC=23
If points are collinear and B is between A and C we can write:
AC=AB+BC
Putting values and finding value of x
[tex]AC = AB+BC\\23=6x+x-5\\23=7x-5\\7x=23+5\\7x=28\\x=\frac{28}{7}\\x=4[/tex]
The value of x = 4 if A, B, and C are collinear points and B is between A and C.

the average motorcycle weighs 32,000 grams. How many kilograms does the average motorcycle weigh?
Answer:
The average motorcycle would weigh 32 kilograms.
Step-by-step explanation:
1 kilogram = 1000 grams
so, to find how many kilograms a motorcycle is, we just need to divide the amount of grams by 1000
32,000 / 1000 = 32 kg
A state Motor Vehicle Department requires learners to pass a written test on the motor vehicle laws of the state. The exam consists of twenty true-or-false questions, of which eighteen must be answered correctly to qualify for a permit. In how many different ways can a learner who answers all the questions on the exam qualify for a permit
Answer:
211 ways
Step-by-step explanation:
Given :
Number of questions = 20
Number of correct correct questions to be answered in other to qualify should be atleast 18
Hence,
Correct questions could be either 18, 19 or 20 ;
Using combination :
nCr = n! ÷ (n-r)!r!
20C18 = 20! / (20 - 18)!18!
20C18 = (20* 19) / (2 * 1) = 190 ways
20C19 = 20! / (20-19)!19!
20C19 = 20 / 1 = 20 ways
20C20 = 20! / 0! 20! = 1 ways
Hence, total number of possible ways = (190 + 20 + 1) = 211 ways
if x is the first of two consecutive integers, express the sum of the two integers in terms of x
Answer:
2x+1
Step-by-step explanation:
x = 1st integer
x+1 = next consecutive integer
The sum is
x+ (x+1)
Combine like terms
2x+1
let the first integer be x and the second be x + 2
then the sum is x +x+2 = 2x +2
