Find the sum.
-19 + (-5)
Answer:
-24
Step-by-step explanation:
Since there is a -5, it will go backward. Imagine there is a -19 point on a number line. It will have to go 5 back because it says negative.

Zach bought 8 pieces of bubble gum that were $0.20 each. He used a number line to find the total cost. Choose the numbers to complete the sentences.
Answer:
He moved 7 hash marks and the product is $1.60
Step-by-step explanation:
It’s says he starts at 0.2 on the number line, so that’s the second hash mark after the 0. If you move to the right on each hash all the way til the 2, you moved 7 times.
The product of 8 x .20 = 1.60

Pls someone help me with this question
Step-by-step explanation:
remember, i = sqrt(-1)
you know what an exponent means, right ?
it means you multiply the enclosed term that many times with itself.
when you envision this as a long chain of (1+i)/(1-i) multiplications, you can see you can group them into pairs, and then multiply these pairs - just half the times than for the single terms.
so,
((1+i)/(1-i))²⁰²⁰ = ((1+i)/(1-i))² ^ 1010
to get an idea what the result of the long chain of multiplications might be, let's start with the square and see, if we can find a pattern, that we then can use to come to a conclusion about the total result.
((1+i)/(1-i))² = (1+i)²/(1-i)²
(1+i)² = 1×1 + 1×i + 1×i + i² = 1 + 2i - 1 = 2i
(1-i)² = 1×1 - 1×i - 1×i + i² = 1 - 2i - 1 = -2i
so,
((1+i)/(1-i))² = 2i/-2i = -1
aha !
so,
((1+i)/(1-i))² ^ 1010 = (-1)¹⁰¹⁰
just to be sure you understand, we use the same trick again
(-1)¹⁰¹⁰ = (-1)² ^ 505 = 1⁵⁰⁵ = 1
as 1 to any power is always 1.
so, the right answer is A.
remember, a negative number to an even power results always in a positive number. and to an uneven/odd power in a negative number.
again, because such an exponent is only the summary of many multiplications.

can someone please help me with number 4,6,9,10
1 - 2x + 3y for x = -2 and y= -5
Answer:
All you need to do is plug the values and then simplify!
[tex] \large{ \tt{ - 2x + 3y}}[/tex]
Plug the value of x and y :[tex] \longrightarrow \: \large{ \tt{ - 2 \times ( - 2) + 3 \times ( - 5)}}[/tex]
When negative integer is multiplied by negative integers , we get positive integer & when positive integer is multiplied by negative integer , we get negative integer.[tex] \longrightarrow \large{ \tt4 + ( - 15){}}[/tex]
[tex] \longrightarrow \large{ \tt{4 - 15}}[/tex]
[tex] \longrightarrow{ \large{ \boxed{ \tt{ - 11}}}}[/tex]
Hence , Our simplified answer is -11 .~Hope this helps! *Let me know if you have any other queries regarding my answer ! <3

Describe what is meant by the slope of a non-vertical line. Explain how your description relates to the definition of slope.
Answer: A verticle line does not have a slope.
Step-by-step explanation: Slope is the rate of change of y for each change in x. y = 2x is a line with slope of 2. Each time x is incremented by 1, y will increase by twice (2x) that amount. There is no slope to a verticle line, unless you want to call it infinite. The value of y is not defined by x.
Claire's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y represented by the equation y = 56 + 7.1x, where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 92?
the change in expected quiz for every additional one hour students spend on their homework.
a student's expected quiz score if they spent 1 hours on their homework.
the number of hours a student should spend on their homework to expect a score of 92 on the quiz.
a student's expected quiz if they spent 92 hours on their homework.
Answer: t = 5.7 hours
Step-by-step explanation:
y=56+7.1x where x is the time spent studying. If y=92, this equation would preduct that the student spent t hours studying. Find t:
92=56+7.1x
36=7.1t
t = 5.07 hours to achieve the 92 score.
Answer: The number of hours a student should spend on their homework to expect a score of 97 on the quiz

find the value of each variable 2x+4x+108
Answer:
Step-by-step explanation:
2x + 4x + 180
We have to do combine like terms.
2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.
All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.
