Answer:
(0,7)
Step-by-step explanation:
This equation is already in slope-intercept form, (y=mx+b), where m is the slope, and b is the y-intercept.
From the equation, we see that (0,7) is the y-intercept.

Andre received and spent money in the following ways last month. For each example, write a positive or negative number to represent the change in money from his perspective.
His uncle gave him $25 as a present.
Step-by-step explanation:
Let the amount of money Andre has be $A.
Answer:
+25
Step-by-step explanation:
I know this is old but since it says his uncle GAVE him 25$ as a present, that means he earned money not lost money. So it would be +25.

The measure of the minor arc BC is 63º. What is the measure of ZBAC?
Answer:
measure or arc BAC should be 297 degrees (with assumptions)
Step-by-step explanation:
Assumption 1: the cap Z in your question is actually an angle symbol
Assumption 2: A is the center of the circle
IF these assumptions are true, then the measure of arc BAC is 36 - 63 = 297 degrees
12.) Rachel is comparing the cost of two parking garages. Garage A charges a flat fee of $6 to park plus $0.50 per hour.
Garage B charges a flat fee of $2 to park plus $1 per hour. Write an equation then find after how many hours will the
cost at garage A and garage B be the same? What will that cost be? (4 points total)
Answer:
The equation: 6 + 0.5x = 2 + 1x
How many hours till the cost is the same: 8 hours
What will the cost be: $10
Step-by-step explanation:
6 + 0.5x = 2 + 1x
subtract 0.5x from both sides
6 = 2 + 0.5x
subtract 2 from both sides
4 = 0.5x
divide both sides by 0.5
x = 8
Lets check our work:
Garage A:
6 + 0.5(8)
6 + 4 = 10
Garage B:
2 + 1(8)
2 + 8 = 10
After 8 hours the price for both garages will be equal at $10

Which equation would you use to solve the following situation?
Ms. Green has 18 pencils at her desk. Students borrow some of the pencils, and 6 pencils are left at the end of the school day. How many pencils were borrowed?
x - 6 = 18
18 - x = 6
18 + 6 = x
Answer:
18-x=6
Step-by-step explanation:
because
if you have eighteen and some were borrowed and 6 were left so it will be subtracted
Answer:
18 - x = 6
Step-by-step explanation:
In any equation x is the unkown you are trying to figure out.
In a word-problem-solving question its helpful to set out what you know and what you dont know:
You know the original number of pens = 18
You know the final number of pens = 6
You dont know how many pens were taken.
Therefore x is the difference between 18 and 6.
18 pens take away x pens is equal to 6
hence 18 - x =6
What is the value of x in the triangle? A. 21 B. 10 C. 7 D. 7√3
Answer:
A.21
Step-by-step explanation:
We can use trigonometry to slove for sides in this triangle...
Using the 60 degree angle...we can solve for x.
We are dealing with adjacent and opposite sides, so we use the tangent function in the calculator.
And since we're using tangent, we have to use opposite/adjacent
We have tan60=x/7sqrt3-multiply the adjacent side(7qrt3) to the other side,
and we have 7sqrt3tan60=x--enter this in to you're calculator, and you should
get an answer of 21

40% Ehrnhardt, 13% petty, 18% waltrip, 29% Gordon
(a) Order the popularity of the choices from greatest to least.
(b) It was estimated that 360 people were surveyed. If this was true, how many people would have voted for Ehrnhardt? Round to the nearest whole number. Show your work.
(c) 65 people voted for Petty. Was the estimate of total voters from Part (b) accurate? Explain.
Answer:
(a) Earnhardt (40%), Gordon (29%), Waltrip (18%), and Petty (13%)
(b) 144, work is below
(c) No
Step-by-step explanation:
(b)
convert 40% to a decimal by dividing by 100 = 0.4
360 x 0.4 = 144 people voted for Earnhardt
(c) converting Petty's percentage to a decimal, we get 0.13. 360 x 0.13 = 46.8, or 47 people, not 65.
Waltrip's percentage, 0.18 x 360 = 64.8, or 65 people.

What is the LCM (least common multiple) of 2 and 7
Answer:
14
Step-by-step explanation:
Answer: 14
Step-by-step explanation:
The greatest common multiple of 2 and 7 is 1, because they are both prime numbers (numbers that cannot be divided by anything other than one or themselves).
Why bother with the greatest common multiple?
There's a very sneaky formula you can do to calculate the LCM with this.
[tex]lcm(a, b) = \frac{|a * b|}{gcd(a, b)}[/tex]
where lcm(a, b) = the least common multiple of integers a and b (1)
a = integer a (2)
b = integer b (7)
gcd(a, b) = greatest common divisor of integers a and b
So let's use it, we have all the available numbers.
[tex]lcm(a, b) = \frac{|2 * 7|}{1} = 14[/tex]

Danielle constructs a scale model of a building with a rectangular base. Her model is 2 inches in length and 1 inch in width. The scale on the model is 1 inch = 47 feet. What is the actual area, in square feet, of the base of the building? in ft2
Answer: The actual area of the base of the building = 4418 square feet.
Step-by-step explanation:
Dimensions of model: 2 inches in length and 1 inch in width.
The scale on the model is 1 inch = 47 feet.
Actual length = 2 x (47 feet) = 94 feet
Actual width = 1 x 47 feet = 47 feet
Actual area of base of building = (Actual length) x (Actual width)
= 94 x 47 square feet
= 4418 square feet
Hence, the actual area of the base of the building = 4418 square feet.

Complete the missing value in the solution to the equation.
( _ , 0 )
Answer:
(4y/3, 0) or if there are no options, it's probably (0, 0)
Step-by-step explanation:
2x + 3y = 5x - y
So we are trying to find the missing value in the solution (_, 0)
We are looking for the x-intercept/root if the coordinate is in this way: (_, 0)
So to find the root, We are solving for x
2x + 3y = 5x - y
First, subtract 5x from bth sides
2x + 3y - 5x = 5x - y - 5x
2x + 3y - 5x = -y
Add like terms
-3x + 3y = -y
Now, subtract 3y from both sides
-3x + 3y - 3y = -y - 3y
-3x = -4y
Divide both sides by -3
-3x/-3 = -4y/-3
x = -4y/-3
We are not done yet because the answer above is not quite right. A negative number divided by a negative number results in a positive number.
So x = 4y/3
Now that we found x, we can input it to the coordinate
(4y/3, 0)
