Answers
Answer:
C) Both (1 , 11) and (-1, -5)
Step-by-step explanation:
y = 8x + 3
Plugin x = 1 and y = 11 in the equation
11 = 8*1 + 3
11 = 8 +3
11 = 11
So, (1 , 11) is a solution.
Plugin x = -1 and y =-5 ,
-5 = 8*(-1) + 3
-5 = -8 + 3
-5 = -5
So, (-1 , -5) is also a solution

a line containing the points (4, y) and (-3, 2) has a slope of 3/2.
Answers
Answer:
y=14.5
Step-by-step explanation:
A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.

Which of the following is equivalent to –(4 + (–7))?
–4 + 7
–4 + (–7)
4 + (–7)
–4 – (–7)
Answers
Answer:
-4+7, -4 - (-7)
Step-by-step explanation:
The given expression can be simplified:
-(4+(-7)) = -(4-7) = -(-3) = 3
The equivalent choices will all equal 3. Testing each choice:
-4+7 = 3
-4+(-7) = -4-7 = -11
4+(-7) = 4 - 7 = -3
-4 - (-7) = -4 + 7 = 3
Only the first and last choice are equivalent to the original expression.

Which equation and solution is correct?
Five-thirds b = 79.50, and the total bill was $47.70.
Three-fifths (79.50) = b, and the total bill was $127.20.
Five-thirds b = 79.50, and the total bill was $212.00.
Three-fifths (b) = 79.50, and the total bill was $132.50.
Answers
Answer:
132.50
Step-by-step explanation:
3/5b = 79.50
b = (79.50) / (3/5)
b = 79.50 * 5/3
b = 397.50/3
b = 132.50
132.50 is the total bill

If 134n = 54eight , calculate n
Answers
The value of 'n' is approximately 4.0896.
To calculate the value of 'n' in the equation 134n = 548, we can isolate 'n' by dividing both sides of the equation by 134.
134n = 548
Dividing both sides by 134:
n = 548 / 134
Evaluating the division:
n ≈ 4.0896
Therefore, the value of 'n' is approximately 4.0896.

Remember: To find the mean you add all the numbers together and divide by how many numbers are there.

Evaluate the function when x= -3,0 and 1. Show work H(x) = 2.5x + 7
Answers
Answer:
H(-3)= -0.5
H(0)= 7
H(1)= 9.5
Step-by-step explanation:
For H(-3)
Substitute all of the x into -3
H(-3)=2.5(-3)+7
2.5 times -3 is -7.5
-7.5+7 is -0.5
So the answer for H(-3) is -0.3
For H(0)
Substitute all of the x into 0
H(0)=2.5(0)+7
2.5 times 0 is 0
0+7 is 7
So the answer for H(0) is 7
For H(1)
Substitute all of the x into 1
2.5(1)+7
2.5 times 1 is 2.5
2.5+7 is 9.5
So the answer for H(1) is 9.5
