Answer:
y = -3x + 5
Step-by-step explanation:
(2, -1); m = -3
y - y1 = m(x - x1)
y + 1 = -3(x - 2)
y + 1 = -3x + 6
y = -3x + 5

A car that is purchased got 24000 is expected to depreciate at a rate of 7% per year. If the function f(x)=ab^x models this situation, which function could be used to find the value of the car after 10 years?
Answer:
FV= 24,000*(1.07^-10)
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $24,000
Decrease rate (d)= 7%
Number of periods (n)= 10 years
To calculate the value of the car after 10 years, we need to use the following formula:
FV= PV*(1+d)^-n
FV= 24,000*(1.07^-10)
FV= $12,200.38
Give coordinates for any three points that are on the same vertical line. Include at least one point that has a mixed number as a coordinate. (Can the numbers be made up? I put in (1 1/2,4), (2,4), (5,4) as the answer. Is that correct?)
Answer: No
Step-by-step explanation:
Points inserted are
[tex](1\ \frac{1}{2},4), (2,4), (5,4)\\[/tex]
As all the points have the same y-coordinate, therefore, they must lie on the same horizontal line of [tex]y=4[/tex]
So, the ingested points are not correct.
Points maybe [tex](1,2), (1, 3), (1,3\ \frac{1}{2})[/tex] as they line on the same vertical line.

Answer:
5. the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution
Step-by-step explanation:
5. 8 = -4(-2) => 8 = 8 (true)
8 = 1/2(-2) + 7 => 8 ≠ 6 (false)
the given ordered pair is not a solution
6. 3 + 5(1) = 8 => 8 = 8 (true)
4(3) - 5(1) = 7 => 7 = 7 (true)
the given ordered pair is a solution
7. -5 = 4 - 9 => -5 = -5 (true)
4 + (-5) = -1 => -1 = -1 (true)
the given ordered pair is a solution
The line passing through (-2,5) and (2,p) has a gradient of -1/2.
Fnd the value of p
Given:
The line passing through (-2,5) and (2,p) has a gradient of [tex]-\dfrac{1}{2}[/tex].
To find:
The value of p.
Solution:
If a line passes through two points, then the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The line passing through (-2,5) and (2,p). So, the slope of the line is:
[tex]m=\dfrac{p-5}{2-(-2)}[/tex]
[tex]m=\dfrac{p-5}{2+2}[/tex]
[tex]m=\dfrac{p-5}{4}[/tex]
It is given that the gradient or slope of the line is [tex]-\dfrac{1}{2}[/tex].
[tex]\dfrac{p-5}{4}=-\dfrac{1}{2}[/tex]
On cross multiplication, we get
[tex]2(p-5)=-4(1)[/tex]
[tex]2p-10=-4[/tex]
[tex]2p=-4+10[/tex]
[tex]2p=6[/tex]
Divide both sides by 2.
[tex]p=3[/tex]
Therefore, the value of p is 3.

1/4(12-3x)
A. 3 - 3/4x
B. 3 - 12x
C. 3 + 3/4x
D. -3 -3x
The expression is equivalent to the 1/4 (12 -3x) is 3 - 3/4x.
What is Expression?In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.
We have the Expression
1/4 (12 - 3x)
Now, using Distributive Property we get
a x (b+ c) = a x b + a x c
Then, 1/4 (12 - 3x)
= 1/4(12) - 1/4 (3x)
= 3 - 3/4x
Thus, the required expression is 3 - 3/4x.

Each container has a base of 4 1/4 yds by 1 2/3 yds. What is the area covered by all the containers?
Answer:
See Explanation
Step-by-step explanation:
Given
Base Dimension
[tex]Length = 4\frac{1}{4}yd[/tex]
[tex]Width = 1\frac{2}{3}yd[/tex]
Required
The base area of all containers
First, calculate the base area of 1 container.
This is calculated as:
[tex]Area = Length * Width[/tex]
[tex]Area = 4\frac{1}{4}yd * 1\frac{2}{3}yd[/tex]
Express as improper fraction
[tex]Area = \frac{17}{4}yd * \frac{5}{3}yd[/tex]
So, we have:
[tex]Area = \frac{17*5}{4*3}yd^2[/tex]
[tex]Area = \frac{85}{12}yd^2[/tex]
The number of containers is not given. So, I will use 'n' as the number of containers.
So, we have:
[tex]Total = n * Area[/tex]
[tex]Total= n * \frac{85}{12}yd^2[/tex]
--------------------------------------------------------------------------------------------
Assume n is 3 (i.e. 3 containers)
The total area is:
[tex]Total= 3 * \frac{85}{12}yd^2[/tex]
[tex]Total= \frac{85}{4}yd^2[/tex]
[tex]Total= 21\frac{1}{4}yd^2[/tex]

Help!! I’ll give brainliest!!
Answer:
A. -1
Step-by-step explanation:
To find the slope, subtract the x-coordinates, subtract the y-coordinates, lastly, divide the differences.
(3,1) (4,0)
3 - 4 = -1
1 - 0 = 1
-1 ÷ 1 = -1
-1 is the slope.
Write an equation to describe the proportional relationship in this table. Explain your thinking and how you got your answer.
PLEASE HELP!! I DONT KNOW WHAT TO DO
Focus on the values in red outside the table (on the left and right sides). As the output increases by 4, the input increases by 1. This leads to the slope being rise/run = 4/1 = 4. The slope is the number just to the left of the x variable. So that's how they ended up with the equation y = 4x.
You can think of it as y = 4x+0, and note how it's in the form y = mx+b
m = 4 = slope
b = 0 = y intercept
The y intercept is the value of y when x = 0.
--------
Now because x = 0 and y = 0 pair up together, we can find the slope a different way: Pick any row other than the first row. Divide the y value over its paired x value. So let's say we pick on row two and we'd get a slope of y/x = 4/1 = 4.
Or we could pick on row three and get y/x = 8/2 = 4.
Picking on the fourth row gets us the slope to be y/x = 12/3 = 4. We end up with the same slope value each time. Again, this trick only works if (x,y) = (0,0) is on the line. Otherwise, you'll need to use the first method or use the slope formula.
For equations like this, we consider them a direct proportion. As x increases, so does y. As x increases by 1, y increases by 4. This is the same throughout the table.
----------
A real world example of this could be that x represents the number of sodas you buy, and if each soda is $4, then y = 4x represents the total cost of buying x number of sodas.
For instance, if you bought x = 10 sodas, then y = 4*x = 4*10 = 40 dollars is what you spend overall.
L=10 in W=5in H=8in find the volume?
Answer:
V = 400in.
Step-by-step explanation:
We are given the measurements of what can be assumed to be a rectangular prism, and we need to find the volume.
When finding volume of a rectangular prism, we need to multiply length by width by height.
So we know all of these,
L = 10in
W = 5in
H = 8in
V = LWH
Substitute :
V = (10)(5)(8)
Mutiply :
V = (50)(8)
Multiply :
V = 400in.
Answer:
the formula to find volume is length times width times height.
Step-by-step explanation:
10 times 5 = 50 then multiply 50 by 8 which equals 400. brainliest :0

A rectangle 9 cm long is equal in area to a square which has a perimeter of 24 cm,find the width of the rectangle.
I want the explanation
Answer:
3cm
Step-by-step explanation:
The length of a rectangle Is 9cm
The perimeter Is 24
Let the width be x
Therefore the width can be calculated as follows
Perimeter= 2(length+width)
24= 2(9+x)
24= 18+2x
24-18= 2x
6= 2x
x= 6/2
x= 3cm
Hence tbe width is 3cm

A 50 foot ladder is set against the side of a house so that it reaches up 30 feet. If Alonso grabs the ladder at its base and pulls it 5 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 25 ft.) Round to the nearest tenth of a foot.
Answer:
21.8
Step-by-step explanation:
The distance for the side of the house will the ladder reach now should be considered as the 21.8 ft.
Calculation of the distance;Since first we have to determine BC i.e.
[tex]= \sqrt{50^2 - 30^2} \\\\= \sqrt{1600}[/tex]
= 40 ft
Now
In the case when Alonso grabs the ladder at its base and pulls it 5 feet farther from the house
So,
[tex]= \sqrt{(50)^2 - (45)^2} \\\\= \sqrt{475} \\\\= 5 \sqrt 19[/tex]
= 21.8 ft.
