For the function y=7-3x, what is the ordered pair for x=5? *
O (-8,5)
O (7,3)
(-3,7)
(5.-8)
[tex]y=7-3x[/tex]
Substitute x = 5
[tex]y=7-3(5)\\y=7-15\\y=-8[/tex]
Therefore, when x = 5, y = -8.
We can write the coordinate point as (5,-8)
Thus, the answer is the last choice.
in triangle, STU, ST = 52, and TU = 39. what is the range of values for the length third side
Answer:
The range of values for the third side is that;
x < 91
Step-by-step explanation:
For us to have a triangle formed, the length of the third side is smaller than the sum of the length of the two other sides
Mathematically;
Let us call the third side x
x < 52 + 39
x < 91
4c < 28
Solve the inequality
Answer:
c < 7

Bus A and Bus B leave the bus depot at 5 pm. Bus A takes 30 minutes to complete its route once and bus B takes 35 minutes to complete its route once. If both buses continue to repeat their route, at what time will they be back at the bus depot together?
Answer:
8:30 pm
Step-by-step explanation:
Bus A and Bus B leave the bus depot at 5 pm. Bus A takes 30 minutes to complete its route once and bus B takes 35 minutes to complete its route once. If both buses continue to repeat their route, at what time will they be back at the bus depot together?
We solve the above question using the Lowest Common Multiple Method.
We find the Multiples of 30 minutes and 35 minutes
Multiples of 30:
30, 60, 90, 120, 150, 180, 210, 240, 270
Multiples of 35:
35, 70, 105, 140, 175, 210, 245, 280
Therefore,
LCM(30, 35) = 210
The Lowest Common Multiple = 210. This means that bus A and bus B will be back at the same depot together after 210 minutes.
We add 210 minutes to 5pm
5 pm + 210 minutes
= 5 pm + 3 hours 30 minutes
= 8:30 pm
Bus A and Bus B will be back at the depot together by 8:30 pm.
Jamie went to the movies with her twin sister, Jenna. They bought one large soda for $4.95 and 3 boxes of candy. Each box of candy cost the same amount. They spent a total of $18.45. Select the equation that best represents how you would solve for c, the cost of each box of candy?
Answer:
The Equation we can use to solve for the cost of each box of candy =
4.95 + 3b = 18.45
The cost of each box of candy = $4.5
Step-by-step explanation:
Let the number of boxes of candy be represented by: b
Each box of candy cost the same amount
Hence from the question above, we have the Equation:
$4.95 + 3b = $18.45
4.95 + 3b = 18.45
3b = 18.45 - 4.95
3b = 13.5
b = 13.5/3
b = 4.5
The cost of each box of candy = $4.5

The equation of sets is given by n(A∪B) = n(A) + n(B) - n(A⋂B)
What is Set Theory Formula?
The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.
Given data ,
Let the equation be represented as A
The value of A is
n(A∪B) = n(A) + n(B) - n(A⋂B)
So , from the given Venn diagram , we get
The number of people who have been to the United States and Australia is given by A = 2
The number of people who have been to Australia and not been to United States is B = 5
The number of people who have not been to Australia but been to United States is C = 6
The number of people who have not been to Australia and not been to United States is D = 4
Hence , the equation is solved by sets

A cookie recipe calls for 1 2/3 cup of sugar. If you plan on changing the recipe to make 2 1/2 times as much. How much sugar will you need?Write your answer as a Mixed number or improper fraction in the simplest form.
Answer:
= 4 1/6 ---------------> final answer
Step-by-step explanation:
1 2/3 cup of sugar
That is : 5/3 cups of sugar for 1 cookie recipe
So for 1 recipe ------------- 5/3 cups of sugar
hence for 2 1/2 recipe ---------------> (5/3) * (5/2)
= 25/6
= 4 1/6 ---------------> final answer
Answer:

The component form and magnitude of the vector is (-7, 2) and √53 option third is correct.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
We have a vector shown in the picture.
The coordinate for tail = (6, 2)
The coordinate for arrow = (-1, 4)
Coordinate for vector = (-1-(6), 4-(2)) = (-7, 2)
The magnitude:
[tex]\rm M=\sqrt{(-1-6)^2+(4-2)^2}[/tex]
M = √53
Thus, the component form and magnitude of the vector is (-7, 2) and √53 option third is correct.

please help me find the slope of the graph thank you a, b, c, d (picture)
Answer:
D: -75 the balloon is descending at a rate of 75ft per minute
Step-by-step explanation:
To find the slope of any graph, take two points on the graph and subtract them y/x so to get this answer is used the points (0,450) and (2,300) and subtracted the y-values over the x-values
450-300=150
0-2=-2
150/-2 = -75
that is the slope and since it is negative and the slope itself is a diagonal line going towards the x-axis you know it’s descending.

Joe has dimes and nickels in his piggy bank totaling $1.45. The number of nickels he has is 5 more than twice the number of dimes, d. Write an equation that can be used to find the numbers of dimes, d, Joe has.
The number of dimes Joe has is 6.
Joe has dimes and nickels, the total amount is $1.45
We have to find the number of dimes Joe has.
Suppose the number of dimes is d, so we have the number of nickels is 2d + 5
Now from the question, we get an equation:
0.10d + 0.05( 2d+ 5) = $1.45
To know the value of d we need to solve the equation:
0.10d + 0.10d + 0.25 = 1.45
0.20d = 1.20
d = 120/20
= 6
Hence we get the total number of dimes Joe has is 6.

PLEASE HELP!!!!!!!!!!!!!!! A small coffee cup holds 75% as much as a large coffee cup. If the small holds 36 units, how much does the large coffee cup hold?
Answer:
48 units
Step-by-step explanation:
Let x = the amount the large cup holds
36 = 75% of x
36 = .75x. (The word "of" indicates you will be multiplying)
36 ÷ .75 = x
48 = x

To work out 20 - 5(3) you would multiply 5 and 3 first and then add the 20
to get a value of 35. Can you start at 35 and reverse those two steps to get
back to 32 Explain the two steps you would take to do that.
Answer:
You would get 5.
Step-by-step explanation:
According to the order of operations ( GEMDAS or PEMDAS ), in a problem the first step is grouping.
20 - 5(3) = 20 - 15, because 5 * 3 is 15 and parenthesis is a sign of multiplication. Then you would get:
20 - 15 = 5.
Here we would not inverse the subtraction sign, because there is an operation before the grouping
Would reverse operation:
20 - ( 5 + 3 )
Would NOT reverse operation:
20 - 5(2) Operation before the subtraction
