Answer:
3x3x3x3
Step-by-step explanation:
1. 4 is the exponent so you would put down (-3) 4 times but, since the -3 is in parentheses it automatically becomes positive.
2. So, instead of writing (-3)x(-3)x(-3)x(-3) or -3x-3x-3x-3 you would write 3x3x3x3.

sole the equation. check your solution 2.5 y + 6=4.5y-1
Answers
Answer:
3.5 = y
Step-by-step explanation:
2.5y + 6 = 4.5y - 1
2.5y + 7 = 4.5y
7 = 2y
3.5 = y
Check:
2.5y + 6 = 4.5y - 1
2.5(3.5) + 6 = 4.5(3.5) - 1
2.5(3.5) + 7 = 4.5(3.5)
8.75 + 7 = 15.75
15.75 = 15.75
Answer:
[tex]y=3.5[/tex]
Step-by-step explanation:
[tex]2.5y+6=4.5y-1[/tex]
Start by subtracting [tex]6[/tex] from both sides of the equation:
[tex]2.5y=4.5y-7[/tex]
Subtract [tex]4.5y[/tex] from both sides of the equation:
[tex]-2y=-7[/tex]
Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]-2[/tex]:
[tex]y=3.5[/tex]
_
Check your solution by substituting the solved value of [tex]y[/tex] ([tex]3.5[/tex]) into the initial equation:
[tex]2.5(3.5)+6=4.5(3.5)-1[/tex]
[tex]8.75+6=15.75-1[/tex]
[tex]14.75=14.75[/tex]
Since both sides of the equation are equal to each other, our solution is correct!
y=8x-18 find the intercepts of the line
Answers
x-intercept = 9/4
-18 is the y intercept
The slope is in y=mx+b form,
And b is the y intercept. Mx is the slope(m) and x is the variable, in this case 8x
So slope is 8, and y intercept is -18
A plane can carry 360 passengers. On a particular day, there are 240 passengers on the plane. Identify the correct inequality and the solution to show how many more passengers the plane can carry?
Answers
Answer:
p + 240 ≤ 360; p ≤ 120
Step-by-step explanation:
The inequality that shows the number of more passengers to carry by plane is 240 + x = 360.
The number of more passengers is 120.
What is inequality?It is a statement of an order relationship
- greater than,
- greater than or equal to,
- less than,
- less than or equal to between two numbers or algebraic expressions.
We have,
Number of passengers in a plane = 360
Number of passengers in a day = 240
The inequality represents the number of more passengers that can carry:
240 + x = 360
Where x is the number of more passengers.
Find x.
240 + x = 360
Subtract 240 on both sides.
240 + x - 240 = 360 - 240
x = 120
Thus,
The inequality that shows the number of more passengers to carry by plane is 240 + x = 360.
The number of more passengers is 120.

Write the equation of the line that passes through the points (-7, -3) and
(-2,-1)
Answers
Answer:
y = 2/5x - 1/5
Step-by-step explanation:
The first step is to find the slope. We can do this by doing y2- y1/x2 - x1, you can name any number 1 or 2 as long as the x and y are right.
-1 - (-3)/-2 - (-7) = 2/5
Now that we know that the slope is 2/5 we can use the formula
y - y1 = m(x - x1)
y + 3 = 2/5(x +7)
y + 3 = 2/5x + 2 4/5
y = 2/5x - 1/5

The length of a rectangle is 3 less than twice the width. The perimeter of the rectangle is 66. Find the length and width of the rectangle.
Answers
Answer:
15.
Step-by-step explanation:
L + L + W + w = 66
L= w+3
W+3 + w+3 + w + w = 66
4xw + 6 = 66
4xw = 66 - 6
4xw = 60
W + W +w +w =60
W= 60/4
W=15
L = 15+3 (=18)
15+15+18+18=66

For 2 minutes, a satellite traveled at a steady speed. It traveled 380 kilometers around Earth in that time. What was the satellite's speed?
Answers
Answer: The satellites speed was 190 kilometers per minute.
Step-by-step explanation:
The formula for speed is calculated as:
Speed = Distance/Time
where,
Distance = 380 kilometers
Time = 2 minutes
Speed = Distance/Time
Speed = 380km/2min
Speed = 190km/min
The satellites speed was 190 kilometers per minute.
Therefore, the correct answer is C.
Karen and Wayne need to buy a refrigerator because theirs just broke. Unfortunately,their savings account is depleted, and they will need to borrow money in order to buy a new one. Sears offers them an installment loan at 15% (add-on rate). If the refrigerator at Sears costs $1,500 plus 5% sales tax, and Karen and Wayne plan to pay for the refrigerator for 2 years, what is the monthly payment?
Answers
Answer:
$53.14
Step-by-step explanation:
Add-on-rate = 16%
Cost = $1,578 + Sales tax = 5%(5% of $1578 = $78.90)
Time = 3 years
Total amount borrowed = 1578 + 78.90 = $1656.90
Charges = 16%
So, 16% of 1656.90
= 16/100 * 1656.90
= $265.10
Total amount would be = 1656.90 + 256.10 = $1913
No. of months in 3 years = 36months
∴ Monthly payment = [tex]\frac{1913}{36}[/tex]
= $53.14.

Can someone pls explain to me how Identify the domain and range of a graph!!,
Answers
Answer:
Ok
Step-by-step explanation:
So, the domain is the set of all possible values that can be inputted into the function. Or where is function on the x axis is the function defined. The range is similar but on the y axis. In this case, the function you have there appears to go on to infinity (I assume that is what the arrow means) and so the range would be [-1, -infinity) and domain [1, infinity). Brackets are important here because it shows that the function is still defined at point (1,-1), therefore, I used [ bracket symbol (I again assumed that the shaded in black dot at point (1,-1) means that the function is closed at that point and that when it is not shaded in, it is open). I feel like I didn't explain very well but good luck and hopefully someone does a better job that what I did.

A school printed 315 tickets to the spring dance. There are 255 tickets left. Which equation can be used to find how many tickets have been sold?
Answers
You didn't add any options but here's one that would work.
315 - 255 = 60
When there is a problem asking how many are left, taken, sold, given, etc. You are usually dealing with subtraction.
Hope that helps and have a great day!
Answer:
The last choice (x+255=315 )
Step-by-step explanation:
This is because we know the total number of tickets is 315 and they have 255 left. So, x + 255 = 315. Because you subtracted __ from 315 to get 255. You can rewrite that as __ + 255 = 315 or x + 255 = 315
