Misha found that the equation –|2x – 10| – 1 = 2 had two possible solutions: x = 3.5 and x = –6.5. Which explains whether or not her solutions are correct?
She is correct, because both solutions satisfy the equation.
She is not correct, because she made a sign error.
She is not correct, because there are no solutions.
She is not correct, because there is only one solution: x = 3.5.
She is not correct, because there are no solutions. (Option C).
What is an equation?An equation refers to any mathematical statement that contains the equality sign. Now we can see in the equation that there is a negative sign before the absolute value.
Now we have;
–|2x – 10| – 1 = 2
–|2x – 10| = 3
This is not possible because the absolute value does not return a negative value and the expression can never equal 3.
Thus, she is not correct, because there are no solutions.

Rich and Betsy Cuik started a small business. They manufacture a microwavable coffee-to-go cup called Cuik Cuppa Coffee. It contains spring water and ground coffee beans in a tea-bag-like pouch. Each cup costs the company $1.00 to manufacture. The fixed costs for this product line are $1,500. Rich and Betsy have determined the demand function to be q = -1,000p + 8,500, where p is the price for each cup.

The probability that Terry buys a sandwich is 0.4.
The probability that Terry gets the bus is 0.9.
Assuming the events are independent, what is the probability that Terry buys a sandwich and gets the bus?
Answer:
The probability that Terry buys a sandwich and gets the bus is 0.36
Step-by-step explanation:
When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.
Let A be the event that Terry buys a sandwich
Let B be the event that Terry gets the bus
Then
[tex]P(A) = 0.4\\P(B) = 0.9[/tex]
When two events are independent, their probabilities are multiplied i.e.
[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]
Hence,
The probability that Terry buys a sandwich and gets the bus is 0.36
There are 6 people in George's family. How much did George's mom pay for tickets? Show how you found your solution.
Answer:
$75
Step-by-step explanation:
To find out how much George's mom paid for the 6 tickets, first find the unit rate, that is cost per ticket.
The unit rate/constant of proportionality between cost of tickets (y) and number of tickets (x) can be calculated using the coordinates of any points on the graph.
Using (4, 50), this means that 4 tickets cost $50.
Unit rate/constant of proportionality = y/x = 50/4 = 12.5
This means a ticket costs $12.5.
Therefore, 6 tickets would cost:
6 tickets × $12.5 = $75.
George's mom paid $75 for the tickets?

identify an equation in slope-intercept form the line parallel to y=-3x+7that passes through (2,-4)
Answer:
y=-3x+2
Step-by-step explanation:
Same slope = parallel. You can aso double check this answer by either graphing using the desmos online graphing calculator or by plugging in the point into the equation y = -3(2) + 2 --> y = -6 + 2 --> y = -4, so we are correct.
Answer:
y=-3x+2
Step-by-step explanation:
In this equation the slope is the same as the original equation (-3), but has a different y-intercept meaning that this line is parallel. As for satisfying the requirement that the line is parallel and passes through (2,-4), I plugged the coordinates into the equation y=-3x+b to get -4=-3(2)+b, and then found what b would have to equal to make the equation true.
(plus I put my answer into a graphing calculator to check my work)

You guys are life savers but does anyone know the answers to these questions? I’m so confused rn
Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be [tex]\frac{3}{-1}[/tex] , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.
1. What is the m value (slope) and the b value (y-intercept)
in the equation y = 4x - 2 (m=
b=
2. What is the formula for slope?
[tex]y=4x-2[/tex]
m = 4 and b = -2
Formula to find slope can be meant 2 ways.
( 1 ) m = rise/run
( 2 ) [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] if it's a small text then it's m = y2-y1 / x2-x1

What is the slope of the line that passes through the points (-6 , -4) and ( -12 , -4)? Write in simplest form plssss!
Answer:
the slope is zero
Step-by-step explanation:
Answer:
I think that: slope (m) = 0
Step-by-step explanation:
the equation of slope is m = y2-y1/x2-x1
so, y2 = -4, y1 = -4, and x2=-12, and x1= -6
Just substitute them into the equation:
m = -4 - -4 / -12- -16
m = 0
The slope is equal to 0

A grocery store is selling peaches for $0.98 per pound. Is this a function or Not function
Answer:
This is a function. Use y=mx+b equation
Step-by-step explanation:
To find the x and y values, simply plug in 0.98 to m. For every pound of peaches, you pay $0.98. The equation would be y=0.98x, where x is the number of pounds of peaches and y is the total cost.

The table below represents the number of hours a student worked and the amount of money the student earned. What is the initial amount this student is paid? (Base pay, when number of hours, h = 0) I’LL PAY YOU 30 DOLLARS IN CASHAPP RIGHT NOW WHEN YOU DO IT!
The initial amount this student is paid is 0 and this can be determined by using the two-point slope form of the line.
Given :
The given table represents the number of hours a student worked and the amount of money the student earned.
The following steps can be used in order to determine the initial amount this student is paid:
Step 1 - The two-point form of the line can be used in order to determine the initial amount this student is paid.
Step 2 - So, the linear equation that represents the given situation is:
[tex]\rm \dfrac{d-50}{h-8}=\dfrac{93.75-50}{15-8}[/tex]
Step 3 - Simplify the above expression.
[tex]\rm \dfrac{d-50}{h-8}=6.25[/tex]
d - 50 = 6.25h - 50
d = 6.25h
Step 4 - Now, substitute the value of (h = 0) in the above expression.
d = 0
Therefore, the correct option is D) There is no base pay.
