Answer:
Part 1
1.) -105
2.) 120
3.) 15
4.) -200
5.) 40
6.) 16
7.) 240
Step-by-step explanation:
1.) Do 7 x 15, which is 105, then since 15 is a negative and 7 is positive, the product is negative.
2.) Do 5 x 24, which is 120, and sine both 5 and 24 are negative, they cancel each other out and the product is positive.
3.) Do 75 / 5, which is 15, and since both 75 and 5 are negative, they cancel each other out and the quotient is positive.
4.) Do 25 x 8, which is 200, and since 25 is negative and 8 is positive, the product is negative.
5.) Do 120 / 3, which is 40, and since both 120 and 3 are positive, the quotient stays positive.
6.) Do 80 / 5, which is 16, and since both 80 and 5 are negative, they cancel each other out and the quotient is positive.
7.) Do 16 x 15, which is 240, and since both 16 and 15 are negative, they cancel each other out and the product is positive.

Answer: it’s 66 I got it right
Step-by-step explanation:
Answer:
The answer will be 66 !!
Step-by-step explanation:
The answer will be 66 because if you look at the chart you can see how much money is cost to rent a bike for each hour. So for Ari, as he rented a bike it costs 9 dollars per hour. So Ari rented the bike for 4 hours, so multiply 4x9=36. Now for Meg, she rented a scooter for 3 hours, each hour means 10$. Now 3x10=30, Then just add 36+30 you get 66!

a conference hall has 33 rows.the last row contains 80 seats each row has two fewer seats than the row behind it.how many seats are there second to the last row?
Answer:
there are 84 seats in the second to the last row
Step-by-step explanation:
Given that
each row has two fewer seats than the row behind it
It means that
if first row has x seats then
no of seat in second row has (x-2) seats.
and similarly
no of seat in third row =no of seat in second row - 2seats.
no of seat in third row = (x-2) seat - 2 seats = x - 4 seats
_____________________________________________
Given that
last row has 80 seats
let the number of seat in first to the last row be x
then number of seat in last row = x-2
we know number of seat in last row = 80
thus
x - 2 = 80
x = 82
Thus,
the number of seat in first to the last row is 82
Similarly let the number of seat in second to the last row be y
then number of seat in first to the last row = y-2
since number of seat in first to the last row is 82
thus
y-2 = 82
y = 82 + 2 = 84
Thus, there are 84 seats in the second to the last row.

**Find the component form of the resultant vector.**
Answer:
[tex]\overrightarrow{AB}+\overrightarrow{CD}=(-3,-7)[/tex]
Step-by-step explanation:
Vector Addition
We are given the points A=(1,3), B=(-4,5), C=(-2,10), D=(0,1). Find:
[tex]\overrightarrow{AB}+\overrightarrow{CD}[/tex]
First, find both vectors from the initial and final points:
[tex]\overrightarrow{AB}=(-4-1,5-3)=(-5,2)[/tex]
[tex]\overrightarrow{CD}=(0-(-2),1-10)=(2,-9)[/tex]
Now find the sum of both vector by adding the components separately:
[tex]\overrightarrow{AB}+\overrightarrow{CD}=(-5,2)+(2,-9)=(-3,-7)[/tex]
[tex]\boxed{\overrightarrow{AB}+\overrightarrow{CD}=(-3,-7)}[/tex]

Answer:
75$
Step-by-step explanation:
because 25+50=75
Answer:
The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.
Direct variation is only noticeable at the beginning of the graph after that the function is linear.

Which of the following equations is equivalent to x + y = 10?
Answer:
x + y - 10 = 0
Step-by-step explanation:
x + y - 10 = 10 -10
Move the constant to the left by adding its opposite to both sides
x + y - 10 = 0
The sum of two opposites equals 0
x + y - 10 = 0

determine if the function f(x)=3^(2x-3) is exponential
An exponential function gives a variable raised to the power of x, where the variable is a positive real number
Yes, [tex]\underline{f(x) = 3 ^{(2 \cdot x - 3)}}[/tex] is an exponential function
Reason:
An exponential function is a function that can be written in the form;
f(x) = eˣ
Where;
e = Euler's number, which is the number approximately 2.71828
In the general form, an exponential number is a number given in the form;
f(x) = a·bˣ
Where;
b = A positive real number
The given function; [tex]f(x) = 3 ^{(2 \cdot x - 3)} = \dfrac{3^{2\cdot x}}{3^3} = \dfrac{1}{27} \times 9^x[/tex] is an exponential function
Where;
a = [tex]\dfrac{1}{27}[/tex]b = 9Therefore, the correct response is; Yes, [tex]f(x) = 3 ^{(2 \cdot x - 3)}[/tex] is an exponential function
