Answer:
x = 3 and y = 7
Step-by-step explanation:
Given that,
8x+3y=45 .......(1)
2x+3y=27 ........(2)
We need to solve equations (1) and (2)
Multiply equation (2) by 4.
8x+12y=108 .....(3)
Subtract equation (1) from (3).
8x+12y-(8x+3y)=108-45
12y-3y = 63
9y = 63
y = 7
Put the value of y in equation (1).
2x+3(7)=27
2x+21 = 27
2x = 27-21
2x = 6
x = 3
So, the values of x and y are 3 and 7 respectively.
2/7 = 630/x
2x = 7 × 630
2x = 4410
÷ 2
2205 = x

I have attached a picture of the dot plot that you described. Each dot on the number line represents one answer. So, the number of dots above the number 4 tells us that there were 6 students who have 4 email accounts.
The answer is that <span>
There are exactly 6 students with 4 email accounts.</span>
Answer:
y = |x-1| - 5
Step-by-step explanation:
To shift the graph to the right, you need to subtract from the inside of the absolute value sign.
Answer:
1. - completed
2. expanded = a · a · a · a
3. base = a | exponent = 5 | expanded = a · a · a · a · a
4. - completed
5. base = c | exponent = 3 | expanded = c · c · c
6. base = c | exponent = 4 | expanded = c · c · c · c
7. base = m | exponent = 2 | expanded = m · m
8. base = m | exponent = 3 | expanded = m · m · m
9. power = y⁵ | base = y | exponent = 5
10. power = y⁸ | expanded = y · y · y · y · y · y · y · y
hope this helps ! brainliest ?
