Answers
Answer:
2
Step-by-step explanation:
you can make it like this
(1/4)^ x=1/16
so x=2
This is because when you have a negative exponent like -x to rearrange it to a fraction and change the negative to a positive.
So 4^x would be the denominator and 1 would be the numerator.
So 1 / 4^x = 1 / 16
To achieve 16 from 4 you square it, therefore x = 2

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.
Answers
Explanation: If you isolate the absolute value by adding 1 both sides of the equation, you get -|2x-10|=3. There are no solutions, because the left side of the equation will always be negative and will never equal 3.
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.

There are 6 people in George's family. How much did George's mom pay for tickets? Show how you found your solution.
Answers
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?

What is the slope of the line that passes through the points (-6 , -4) and ( -12 , -4)? Write in simplest form plssss!
Answers
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

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?
Answers
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
