Find the slope and y-intercept.
Answer:
y-intercept = -5, slope = 5/3
Step-by-step explanation:
The y-intercept is where on the y-axis (vertical line) does the graph cross. The slope can be found many different ways. My method for this graph was simply counting up the graph until I got to the point where the graph crosses another whole number on the x-axis and then counted over. This makes sense because slope is rise over run so if you go up 5 (from the y-intercept) and then over 3 (to get to the next whole number point) then your slope is 5/3

4. The length of a rectangle is eight more than
twice its width. The perimeter is 96 feet. Find
the dimensions of the rectangle.
Answer:
length = 104/3 ft
width = 40/3 ft
Step-by-step explanation:
Variables:
L = length
w = width
Set up equations:
L = 8 + 2w2L + 2w = 96Substitute L with the first bullet point equation:
2L + 2w = 96
2(8 + 2w) + 2w = 96
16 + 4w + 2w = 96
16 + 6w = 96
6w = 80
w = 40/3 ft
Find L now that you have the value of the width:
L = 8 + 2w
L = 8 + 2(40/3)
L = 8 + 80/3
L = 104/3 ft
Final Values:
length = 104/3 ft
width = 40/3 ft

What are the coordinates of R' after a dilation by a scale factor of 3, centered at the origin, followed by the translation (x, y) - (x, y + 3)?
A. (9, 8)
B. (12, 18)
C. (9, 18)
D. (9, 24)
9514 1404 393
Answer:
C. (9, 18)
Step-by-step explanation:
Given R(3, 5), a dilation by a factor of 3 will multiply each coordinate to give ...
(9, 15)
Then the translation up by 3 will give you the image coordinates ...
(x, y) ⇒ (x, y+3)
(9, 15) ⇒ (9, 15 +3) = (9, 18)
The coordinates of R' are (9, 18), matching choice C.
_____
Comment on multiple choice answers
As it often does, here it works to "guess" the answer that has the coordinates that are most-repeated. An x-coordinate of 9 is part of 3 answer choices; a y-coordinate of 18 is the only repeated value in the answer choices. If you were to guess, an appropriate guess would be (9, 18). That happens to be correct in this case.
Answer: C. (9,18)
Step-by-step explanation: I have had this question on a quiz before.

8.) Find the value of x.
80°
100 + X
40°
HELP ME PLEASE
In a triangle,
3 angles are:
80
100 + x
40
By angle sum property of triangle,
80 + 100 + x + 40 = 180
220 + x = 180
x = 180 - 220
x = -40

My cookbook says that a salad sauce should be made of 1/3 lemon juice and
2/3 oil. I put 30 ml of oil but my hand slipped when adding the lemon juice
and the total volume is now 70.
How much oil must I now add to have the correct proportions?
Answer:
50ml
Step-by-step explanation:
as u put 30ml oil and u have 70 so 70-30 is 40 which is 40ml lemon juice. as 1 part is lemon and 2 parts oil out 2x40 so 80ml but as u already have 30 in there only put 50 :)
The ticket sales for a concert started at 4:00 P.M. The table shows the linear relationship between the number of tickets remaining and the number of hours since 4:00 P.M.
Which function can be used to find y, the number of tickets remaining x hours since 4:00 P.M.?
a
y = 3,000x + 12,000
b
y = -3,000x + 12,000
c
y = -3,000x + 15,000
d
y = 3,000x + 15,000
Answer:d
Step-by-step explanation:
The function which represents the number of tickets remaining after x hours is b. y = -3,000x + 12,000.
What is a function?A function can be defined as the values of the inputs for which the output is defined. The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
From the given graph we can observe that every hour 3000 tickets were sold.
Assuming hours to be x and tickets remaining at any time is represented
by y and as the tickets were sold we can denote it with a negative sign.
∴ The function which represents the number of tickets remaining after x hours is,
y = -3000x + 12000.
To check whether our function is correct or not we can put any value of x from 1 to 4 in our function.
