Slope = 2
Y intercept = -3
====================================================
Explanation:
We'll use the template y = mx+b
m = slope
b = y intercept
The y intercept always occurs when x = 0. In this case, b = -3 due to the first row of the table.
The slope is m = 2 because each time we increase x by 1, the y value goes up by 2.
So we can say
m = slope = (rise)/(run) = (change in y)/(change in x) = (2)/(1) = 2
Or we can apply the slope formula
m = (y2-y1)/(x2-x1)
using any two points of the table.
--------------------
Since we know m = 2 and b = -3, this means we get
y = mx+b
y = 2x+(-3)
y = 2x-3
solve for x
925 + x = 652
Answer:
x=-273
Step-by-step explanation:
first you move the constant to the right. it should look like this(x=652-925)
then you subtract and you should get -273
The cost of a car battery costs $35 wholesale for the automotive store to buy, but they need to markup the cost 40% for the retail price. How much is the markup amount? And how much is the retail price?
Answer:
The markup amount is $14 and the retail price is $49.
Step-by-step explanation:
You can use the following formula to find the retail price with the information provided:
Retail price=Cost*(100%+markup %)
Cost=35
Markup %= 40%
Now, you can replace the values in the formula:
Retail price=35*(140%)
Retail price=49
Now, you can subtract the cost from the retail price to find the markup amount:
49-35=14
According to this, the answer is that the markup amount is $14 and the retail price is $49.

A car rental agency charges 150 per week +0.45 per mile to rent car express the weekly cost to rent a car if as a function of the number of miles driven during week X
Answer:
The required function is:
[tex]C(x) = 150+0.45x[/tex]
Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get
[tex]C(x) = 150+0.45x[/tex]
Hence,
The required function is:
[tex]C(x) = 150+0.45x[/tex]
Can someone PLEASE solve this quadratic equation by factoring with the steps? :(
y= x squared +2x - 2
Answer:
There are no simple factors to this expression. You can however solve for x, giving you:
x = -1 ± √(y + 3)
Step-by-step explanation:
There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:
[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]

In a survey of 2,000 people who owned a certain type of car, 1,320 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
____% of the people surveyed were satisfied with the car.
(Type a whole number.)
Answer: Total number of those who took part in the survey (T)=2000
Those who were satisfied (t)=1320
Percentage of those who were satisfied (S)=(t/T)*100
S=(1320/2000)*100
S=66%
Therefore only 66% were satisfied

7.) (0, 2)
Slope of (0, 2) and (-10, -16) = 2 - (-16) ÷ 0 (-10) = 18/10 = 9/5
8.) a. Slope of (17, -12) and (17, 8)
8 - (-12) ÷ 17 - 17 = 20 ÷ 0 = undefined
b. Slope of (6, -2) and (-3, 1)
1 - (-2) ÷ -3 - 6 = 3/-9 = -1/3
9.) (-3, 33) and (4, -9)
-9 - 33 ÷ 4 - (-3) = -42/ 7 = -6
10.) Hourly: c = 75h + 15

What is the answer
Answer:
.
Step-by-step explanation:
Answer:
If we are solving for x then the answer is x = 10
Step-by-step explanation:
To solve for x we must first get all the variables to one side
so subtract 1x from both sides
1.50x = 15
divide 1.50 both sides
x = 10
So for dilation when it says to dilate 1/3 how do I solve that (ex. 18, 9)
Answer:
The image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).
Step-by-step explanation:
Let suppose the given point is A(18, 9)
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruentRule to calculate the dilation by a scale factor 1/3 centered at the origin
P(x, y) → P'(1/3x, 1/3y)
Here, P'(1/3, 1/3y) is the image of P(x, y).
It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 1/3.Thus,
A(18, 9) → A'(1/3(18), 1/3(9)) = A'(6, 3)
Therefore, the image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).

A rectangular box has its length and width doubled and its height tripled. The volume of the new box will be
Answer:
volume of the new box = 12 x volume of the initial rectangular box
Step-by-step explanation:
Let the length, width and height of the rectangle be represented by l, w and h respectively.
The volume of a rectangle is given as;
volume = l x w x h
= lwh
From the given question, the dimension of the rectangle are:
new length = l + l = 2l
new width = w + w = 2w
new height = h + h + h = 3h
So that, the volume of the new box is given as;
volume of the new box = 2l x 2w x 3h
= 12 (lwh)
Therefore,
volume of the new box = 12 x volume of the initial rectangular box
