Answer:
B
Step-by-step explanation:
Which phrase matches the equation -3r + 5 = 28?
Group of answer choices
The product of negative three and a number plus five equals twenty-eight.
The sum of negative five plus three times a number equals twenty-eight.
The sum of three and a number times negative five gives twenty-eight.
The product of three times a number equals twenty-eight.
You use substitution to solve a system of equations and, after simplifying the equations, end with an expression that says 0 = 4. What does that say about the the lines and about the number of solutions to the system?
Sample Response: Since the statement is false, there are no solutions to the system of equations. This also indicates that the lines are parallel.
Check all that you included in your response.
□ The equation is false.
□ False equations indicate no solution.
□ No solution indicates a system with parallel lines.
Hope this helps!
Answer:
Check the first two.
Step-by-step explanation:
Since the statement is false, there are no solutions to the system of equations. This also indicates that the lines are parallel.
Answer:
Since the statement is false, there are no solutions to the system of equations. This also indicates that the lines are parallel.

ten less then quotient of a number and 3 is 8
Answer:The answer is 6
Answer:
x =54
Step-by-step explanation:
I assume you need to find the number .
Let x = the number(AKA the variable)
x/3 - 10 = 8
x/3 = 18
x =54
2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.
Answer:
y=x
Step-by-step explanation:
By using the (y2-y1)/(x2-x1), you can find y=mx+b
Points: (30,30) and (60,60)
(60-30)/(60-30)= 30/30=1
Your m value (slope) is 1.
For the y-intercept, your value is 0
The full answer is y=x
As per linear equation, the required equation of the given graph is y = x.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Here, the graph is a straight line.
Therefore, the equation of the given graph must be a straight line.
Again, the graph passes through points (30, 30) and (60, 60).
Therefore, the slope(m) of the given straight line is
[tex]= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\= \frac{60-30}{60-30}\\ = \frac{30}{30}\\ = 1[/tex]
The graph of the straight line passes through the point (30, 30).
Putting this value in the standard equation(y = mx + c), we get:
30 = (1)(30) + c
⇒ c = 0
Therefore, the y-intercept of the straight line is 0.
Now, the required equation of the straight line is
y = mx + c
⇒ y = (1)x + 0
⇒ y = x

B. 157 square inches
C. 491 square inches
D. 1,963 square inches
Answer:
12.5 in^2
Step-by-step explanation:
[tex]C=2\pi r[/tex]
25=2(3.14)r
25=6.28r
Divide by 6.28 on both sides:
3.98089172=r
Now use [tex]\pi r^{2}[/tex]:

Write an algebraic expression that can get you the final price of an item that originally cost $x with 10% off?
Answer:
x - (x*0.1)
Step-by-step explanation:
A percentage is just a fraction/decimal. you'll get 10% of the number with the equation in parentheses, and we need to do that first. then we need to take the original price and subtract 10%

Answer:
may I help u....................
....... m
Step-by-step explanation:
For no. 3
x - 3 = 3 - x
x + x = 3 + 3
2x = 6
x = 6 / 2
x = 3
For no. 4
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = - 8

Write your answer as a fraction or whole number.
Evaluate 3z- 3 when z=7
a 34
b 21
c 18
Answer: C (18)
Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.
Answer:
C
Step-by-step explanation:
Since z = 7 the equation would be 3(7) - 3
You would multiply 3 with 7 and get 21
Then you would subtract 3 from 21 and get 18

Find an equation for each line.
Melanie spent four hours babysitting. She charges $16 up front and then an additional charge per hour. The total amount she earned can be represented by the expression $4x + $16. What expression represents the amount she earns each hour?
Please give me the expression.. if u just say i don't know i will report ;)
Answer:
She earns $4 x is representing the hours.
Step-by-step explanation:
16 is the charge up front.
I can infer that the additional charge is $4 because x represents the hours because we don't know how many hours she's going to spend there.
