Answer:
y = 1/2x - 2.5
Step-by-step explanation:
(15, 5) and (42, 18.5)
Slope:
m=(y2-y1)/(x2-x1)
m=(18.5 - 5)/(42 - 15)
m = (13.5)/27
m = 1/2
y - y1 = m(x - x1)
y - 5 = 1/2(x - 15)
y - 5 = 1/2x - 7.5
y = 1/2x - 2.5
Answer:
2 or 1/2
Step-by-step explanation:
change in y over change in x
you didnt define what what x and what was y so ill provide both answers and you can figure which is correct
42-15/18.50-5 =27/13.5 =2
18.50-5/42-15 =13.5/27 =1/2

Find the mean of the data set: 573, 569, 566, 561, 566, 566, 568.
a. 566
b. 567
c. 561
d. 573
Answer:
b. 567
Step-by-step explanation:
All you have to do is add the whole set, then divide by how many numbers it is.
573+569+566+561+566+566+568= 3969
3969/7= 567
There is 7 numbers in the set, so you add the numbers then divide by 7.
Answer: B is definitely the correct answer because you add up all the numbers then just divide.

Find the value of x, 110°, 4x+2, and if you can help with steps that would be great :,)
Answer:
x = 17
Step-by-step explanation:
The two angles with measures form a linear pair and are supplementary.
The measures of supplementary angles has a sum of 180°.
If you add the two given measures, the sum must equal 180°.
4x + 2 + 110 = 180
4x + 112 = 180
4x = 68
x = 68/4
x = 17

Step-by-step explanation:
Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Which inequality represents the amount she can still spend this month and remain within her budget?
x greater-than 272
x less-than-or-equal-to 272
x less-than 272
x greater-than-or-equal-to 272
Answer:
1200-928 = 272 for the rest of the month Clarissa has to spend.
Step-by-step explanation:
So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over. Option 2 or B.

. Two planes are 1620 miles apart and are traveling toward each other. One plane is traveling 120 mph
faster than the other plane. The planes meet in 1.5 hours. Find the speed of each plane.
Answer:
Step-by-step explanation:
let the speed of one plane=x mph
speed of other plane=x+120 mph
x×1.5+(x+120)×1.5=1620
(x+x+120)×1.5=1620
(2x+120)×1.5=1620
3x+180=1620
3x=1620-180
3x=1440
x=480
speed of one plane=480 mph
speed of second plane=480+120=600 mph

A clock has a diameter of 16 inches. Which measurement is closest to the area of the clock in square inches? 804.25 in2 50.27 in2 25.13 in2 200.96 in2
Answer:
200.96 in2
Step-by-step explanation:
Area of a circle = nr²
n = 3.14
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
diameter = 2r
radius = 16 inches / 2 = 8 in
Area = 3.14 x 8² = 200.96 in²
A clothing store charges a 10% tax on each purchase. If a shopper’s total before tax is $63, how much is the tax? Explain how you got your answer
Answer:
To calculate the sales tax that is included in a company's receipts, divide the total amount received (for the items that are subject to sales tax) by "1 + the sales tax rate". In other words, if the sales tax rate is 6%, divide the sales taxable receipts by 1.06.

Answer:
$5
Step-by-step explanation:
Set up a system of equations
let b be the cost of a bow
let w be the cost of a roll of wrapping paper
This means that
[tex]5b + w = 10\\b + w = 6[/tex]
Subtract the two equations
[tex]5b + w = 10\\- (b + w = 6)\\4b = 4\\b = 1[/tex]
Plug this into the equation b + w = 6
1 + w = 6
w = 5.
This means the cost of a bow is $1 and the cost of a roll of wrapping paper is $5.

Step-by-step explanation:
Let LeRoy's bill be x
Let Cora's bill be y
3*y - 8.59 = x (1)
x + y = 68.29 (2)
Substitute the value of x in (1) into the value of x in (2)
3y - 8.59 + y = 68.29 Combine the ys
4y - 8.59 = 68.29 Add 8.59 to both sides
+ 8.59 8.59
4y = 76.88 Divide by 4
4y/4 = 76.88/4
y = 19,22
x + y = 68.29 Substitute 19.22 for y
x + 19.22 = 68.29 Subtract 19.22 from both sides
- 19.22 -19.22
x = 49.07
The point g (2,2) is translated 3units to the right and 4units up what are the coordinates of this resulting point, g?
Answer:
(5,6)
Step-by-step explanation:
Generally, is the coordinate (x,y) is translated right by a units and up by b units, the resulting coordinate wil be;
g(X, Y) = (x+a, y+b)
To the right is along the positive x axis while up is along the positive y axis
Given a = 3 and b = 4
g(X,Y) = (2 + 3, 2 + 4)
g(X, Y) = (5, 6)
Hence the resulting coordinate of g is (5,6)

Answer:
[tex]\sin Y= \frac{XZ}{XY}[/tex]
[tex]\cos Y= \frac{YZ}{XY}[/tex]
[tex]\tan Y= \frac{XZ}{YZ}[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find [tex]\sin, \cos[/tex] and [tex]\tan[/tex] of angle Y
For angle Y:
[tex]Opposite = XZ[/tex]
[tex]Adjacent = YZ[/tex]
[tex]Hypotenuse = XY[/tex]
The [tex]\sin[/tex] of an angle is calculated as:
[tex]\sin\theta = \frac{Opposite}{Hypotenuse}[/tex]
So:
[tex]\sin Y= \frac{XZ}{XY}[/tex]
The [tex]\cos[/tex] of an angle is calculated as:
[tex]\cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]
So:
[tex]\cos Y= \frac{YZ}{XY}[/tex]
The [tex]\tan[/tex] of an angle is calculated as:
[tex]\tan\theta = \frac{Opposite}{Adjacent}[/tex]
So:
[tex]\tan Y= \frac{XZ}{YZ}[/tex]

HELP PLEASE! What’s the domain and range?
Answer:
Domain → (-∞, -1)∪(-1, ∞)
Range → (-∞, ∞)
Step-by-step explanation:
Given function is,
[tex]\frac{f(x)}{g(x)}=\frac{x^2+2x-5}{2x+2}[/tex]
This function is not defined when the denominator is zero.
2x + 2 = 0
2x = -2
x = -1
Therefore, x = -1 is not in the domain of this function.
And the domain will be,
(-∞, -1)∪(-1, ∞)
For all values of x (except x = -1) we get some output values (value of [tex]\frac{f(x)}{g(x)}[/tex]).
Therefore, range of the function will be (-∞, ∞).

What is the value of n?
Please help quick
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15
