Answer: 32x-8
Step-by-step explanation: 8x times 3 is 24x and 4x times 2 is 8x
24x +8x is 32x
3 times-2 is -6 2 times-1 is -2
-6-2 is -8
so therefore the answer is 32x-8

Answer:
for This you have to find the value of x.
Step-by-step explanation:
just add both of them the equation formed will be
22x - 26 = 19x -17
so you can calculate x
which is x = 3
so put the value in 14x -15
so TU will be 27

Answer:
18
Step-by-step explanation:
60% of 50 is 0.60x50=30
40% of 30 is 0.40x30=12
30-12=18
So 60% of 50 is 18 greater than 40% of 30.

graph the line that passes through( -1,5)perpendicular to a line whose slope is -1/6
Answer:
y - 5 = 6(x+1)
Step-by-step explanation:
if it is perpendicular to a line whose slope is -1/6, the slope of this line is the negative reciprocal which is 6.
y - 5 = 6(x+1)
this is point slope form btw
Bob and Alice have designed and created a website for their high school. The first week they had 5 visitors to the site; the second week, they had 10 visitors; and during the third week, they had 20 visitors. If the trend continues, how many visitors can they expect in the fifth week? Explain your answer.
Answer: 80
Step-by-step explanation:
Number of visitors in first week = 5
Number of visitors in second week = 10
Number of visitors in third week = 20
The common ratio here is = 10/5 = 2
The fifth term will be:
= ar^n-1
where,
a = first term = 2
r = ratio = 2
n = number of terms = 5
= 5 × 2^(5-1)
= 5 × 2^4
= 5 × 16
= 80

Nola was selling tickets at the high school dance. At the end of the evening, she picked up the cash box and noticed a dollar lying on the floor next to it. She said, I wonder whether the dollar belongs inside the cash box or not. The price of tickets for the dance was 1 ticket for $5 (for individuals) or 2 tickets for $8 (for couples). She looked inside the cash box and found $200 and ticket stubs for the 47 students in attendance. Does the dollar belong inside the cash box or not? (justify/defend)
Answer:
yes
Step-by-step explanation:
s + 2c = 47
5s+8c = 200
which one checks as in the other solution does not have a solution in non-negative integers. On the other hand, the analogous system
s + 2c = 47
5s+8c = 201
with solution s=13 and c=17. So, as in the other solution, we conclude that the extra dollar belongs in the cash box, with 13 singles and 17 couples attending the dance.

Clayton needs to reflect the triangle below across the line y = x. On a coordinate plane, triangle A B C has points (5.5, 7), (6, 2), (4, 4). Which statements about the reflection are true? Check all that apply.
Answer:
Clayton could use the relationship (x,y) - (y,x) to find the points of the image.
C’ will remain in the same location as C because it is on the line of reflection.
The image and the pre-image will be congruent triangles.
The image and pre-image will not have the same orientation because reflections flip figures
Step-by-step explanation:
Clayton needs to reflect the triangle below across the line y=x
Which statements about the reflection are true? Check all that apply.
Clayton could use the relationship (x,y) - (y,x) to find the points of the image.Clayton could negate both the x and y values in the points to find the points of the image.C’ will remain in the same location as C because it is on the line of reflection.C’ will move because all points move in a reflection.The image and the pre-image will be congruent triangles.The image and pre-image will not have the same orientation because reflections flip figures.
Solution:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Reflection is the flipping of a figure over a line. If a point A(x, y) is reflected over the line y=x, the new location is A'(y, x).
If the triangle ABC with vertices A(5.5, 7), B(6, 2), C(4, 4) is reflected over the line y=x, the new location would be A'(7, 5.5), B'(2, 6) and C'(4, 4).
A. Clayton could use the relationship (x,y) - (y,x) to find the points of the image. Reflection across the line y = x is the swapping of the x and y coordinates. Option A is correct
B. Clayton could negate both the x and y values in the points to find the points of the image. Option B is wrong
C. C’ will remain in the same location as C because it is on the line of reflection. C is on the line of reflection, hence it remains the same. Option C is correct.
D. C’ will move because all points move in a reflection.
Option D is wrong.
E. The image and the pre-image will be congruent triangles.
Option E is correct. Reflection preserves the shape and length of an object.
F. The image and pre-image will not have the same orientation because reflections flip figures. Option F is correct

Range is the set of y-values that are outputted by function f(x)Step-by-step explanation:
According to the line in the graph, our y-values span from -6 to 9. Since both are closed dot, they are inclusive in the range:
Range: [-6, 9] or -6 ≤ y ≤ 9
Answer:
B
Step-by-step explanation:
The solid circles at both ends of the graph are (- 10, - 6 ) and (0, 9 )
The range is the values of y covered by the graph, that is from - 6 to 9
Since the circles are solid then y can equal - 6 and 9
Thus
the range is - 6 ≤ x ≤ 9

Step-by-step explanation:
Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $8 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y represent the number of hours Leah works at the ice cream shop.
Which pair (x, y) represents hours that Leah could work to meet the given conditions? Select all that apply.
A.
(2.5, 15)
B.
(5, 20)
C.
(7.5, 12.5)
D.
(17.5, 5)
E.
(19, 1)
Answer:
A C
Step-by-step explanation:
Answer:
Step-by-step explanation:
Leah wants to earn at least 120 dollars a month and she has two job options. This is written as
5x + 8y > 120
She also can't work more than 20 hours, leading us to the second equation
x + y = 20
First we solve for one variable
y = 20 - x
then substitute it into the first equation
5x + 8(20 - x) = 120
Solve for x
5x + 160 - 8x = 120
3x = 40
x = 40/3
Then we solve for y
y = 20 - x
y = 20/3
x < 40/3
y > 20/3
B and D will not work because their x+y is greater than 20.
E will also not work because the value is less than 120
the boston weatherman says there is a 75 percent chance of rain for each day of the labor day four-day weekend. if it doesn't rain, then the weather will be sunny. paul and yuri want it to be sunny one of those days for a world war iii preenactment, but if it's sunny for more than one day they won't know what to do with themselves. what is the probability they get the weather they want? give your answer as a fraction.
The probability that Paul and Yuri get the weather they want = 27/64
Given probability for rain = 75% = 3/4
The total probability is considered as 100% or 1.
So the probability for sunny day = 1 - 3/4 = 1/4
Paul and Yuri want a sunny day from labor day 4 -day weekend.
This means 3 days of rain and 1 sunny day. So 3 times the probability for rain and 1 time the probability for sunny day.
This one sunny day can be chosen from 4 days. In other ways there is 4C1 =4 different ways possible to choose 3 days of rain and 1 sunny day from 4 days.
So finally the probability that Paul and Yuri get the weather they want
= [tex]\frac{3}{4}^3 \times \frac{1}{4} \times 4[/tex] = 27/64

What do we mean by domain?The domain of a function is indeed the set of values that can be plugged into it. This set contains the x values in a function like f(x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.So, consider the diagram provided.
The left side of the graph represents the input (x) values, while the right side represents the output (y) values.The domain is the set of all possible input values.Consider the following figure, where the set of input values is:{x | x = -5, -3, 1, 2, 6}Therefore, the domain of the given relation (-6, 0), (2, 1), (-7, -4), (11, 2), (3, 2) is (A) {x | x = -5, -3, 1, 2, 6}.
