Answer:
if x + 0 = 5, the value of x is 5.
Step-by-step explanation:
we discard 0 since it is of no value in the equation. thus, x = 5. i'm not sure if the one next to the plus sign is 0, since there's nothing there, but we'll assume it's 0. however, if it turns out to be another number, just transpose the other number next to 5 (it would be negative), and subtract. that will be your x.
Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. 3x-2y=9 and x-y=5
Answer:
(-1,-6)
Step-by-step explanation:
Use substitution
y=x-5
3x-2(x-5)=9
3x-2x+10=9
x=-1
Plug it in
(-1)-y=5
-y=6
y=-6

Step-by-step explanation:
A rectangular prism as a width of x inches, a length of x^2y
inches, and a height of y^2
inches. Which expression represents the volume in cubic inches of this rectangular prism?
A. x^2 y^2
B. 4x^2 y^2
C. x^3 y^3
D. 4x^3 y^3
Answer:
C
Step-by-step explanation:
The volume of a rectangular prism is given by:
[tex]V=\ell wh[/tex]
The width is x, the length is x²y, and the height is y². Thus, the volume is:
[tex]V=(x)(x^2y)(y^2)[/tex]
Multiply:
[tex]V=x^3 y^3[/tex]
Our answer is C.

Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?
Answer: $3.50
Step-by-step explanation:
He came home with $3.00.
He gave Rene $1.50 which means that $1.50 was deducted from his money.
Pedro gave him $1.00 which added to his money.
Money he had therefore was:
= 3 + 1.50 - 1
= $3.50

What is the minimum value for the function shown in the graph?
Answer:
2.5
The lowest point on the graph, or the minimum is at f(x)= 2.5
The minimum value of the given periodic function is, 2.5
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
A periodic function,
Period = 3π
The value of the function is in the range of (2.5, 4.5)
So,
Maximum value = 4.5
Minimum value = 2.5
Thus, the minimum value is 2.5

The equation y = 1125(1.034)" can be used to approximate the number of cell phone users
who live in a certain city over time, where a represents the number of years after 2000.
Which of the following statements is true?
A
the rate of growth is 34%
B
there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%
D
In the year 2005, there were more than 1350 cell phone users.
Answer: B
there were 1125 cell phone users in 2000.
Step-by-step explanation:
The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.
So the initial number of cell phone users in 2000 was 1125.

Solve. 8 - 2d = c 4c + 3d = 2 c=4 d = -6 C=-4 d = 6 C=4 d = 6 C=-4 d = -6
Answer:
c = -4 d = 6
Step-by-step explanation:
8 - 2d = c 4c + 3d = 2
4(8 - 2d) + 3d = 2
32 - 8d + 3d = 2
32 - 5d = 2
-5d = -30
d = 6
8 - 2(6) = c
8 - 12 = -4 = c

Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. Given that the investment yields 2.7% simple interest annually, how big was the initial deposit?
a. $2,524.50
b. $4,024.03
c. $4,250.00
d. $11,404.88
Answer:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.Solving our equation:
P = 6774.5 / ( 1 + (0.027 × 22)) = 4250P = $4,250.00The principal investment required to get a total amount, principal plus interest, of $6,774.50 from simple interest at a rate of 2.7% per year for 22 years is $4,250.00I do exams and quizzes if your interested!The initial deposit amount is $4,250.00.
Given that,
The worth of an investment is $6774.50The time period is 22 years. The rate of interest is 2.7%.Based on the above information, the calculation is as follows:
We know that
[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]
Now
Investment worth = P + SI
= P + 0.594P
= 1.594P
So,
1.594P = 6774.50
P = $4,250
Therefore we can conclude that the initial deposit amount is $4,250.00.
