Step-by-step explanation:
A negative number(or variable, in this case) is less than 0. For example, which is greater, 3 or -3? 3, right?
In variables, x or a or m or whatever, can also be represented as 1x or 1a or 1m, and so on. So in the question, it's asking which is greater, x or -x? Think of the variables as 1x or -1x.
So 1x is greater.

What is the equation of the line that is parallel to Y= -2/3x+4 and that passes through (-2, -2)
Answer:
y = -2/3x-10/3
Step-by-step explanation:
Y= -2/3x+4
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -2/3
Parallel lines have the same slope
y = -2/3 x+b
Substitute the point into the equation
-2 = -2/3 (-2) +b
-2 = 4/3 +b
Subtract 4/3 from each side
-6/3 -4/3 = 4/3 -4/3 +b
-10/3 = b
y = -2/3x-10/3

7,639.11
7,639.12
Answer:
$7639.12
Step-by-step explanation:
We use the compound formula for accrued value (A) for a principal P deposited at an annual rate "r" over t years
[tex]A = P (1+r)^t[/tex]
In our case, with the given information, the formula becomes:
[tex]A = P (1+r)^t\\A=7500 \,(1.0023)^8\\A = 7639.11602[/tex]
which rounded to the nearest cent gives: $7639.12
A rectangular yard measuring 32ft by 50ft is bordered (and surrounded) by a fence. Inside, a walk that is 3ft wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.
Answer:
528 feet squared
Step-by-step explanation:
the yard has a width of 32 feet and a length of 50 feet. -- area of the yard is 1600 ft sq. The walkway is 3 feet wide throughout the fence, meaning you add 6 to 32 and 6 to 50 to get your measurements for the yard + fence area. -- is equal to 2128
Then you subtract the total fence + yard area from the yard area -- 2128 - 1600 which equals 528 feet sq.

where m is the number of months the car is leased. What is the cost, in dollars, of leasing a car for 32 months?
Answer:
15,900
Step-by-step explanation:
An equation is a way of writing two expressions connected by an equal sign.
If the total cost of leasing a car in m month is given by an equation:
c = 450m + 1500
The total cost in dollars, of leasing a car for 32 months is $15,900.
What is an equation?An equation is a way of writing two expressions connected by an equal sign.
Example:
2x = 3x + 5 is an equation.
We have,
The cost of leasing a new car per month = $450
Down payment = $1500
The total cost of the lease is given as:
c = 450m + 1500
m = number of months.
The total cost of the car for leasing in 32 months:
c = 450 x 32 + 1500
c = 14,400 + 1500
c = 15,900
Thus,
The total cost in dollars, of leasing a car for 32 months is $15,900.

Answer/Step-by-step explanation:
The 7 problems Calvin made mistakes in are as follows:
1. 76,450,000
We are moving the decimal point to our left by 7 decimal places. Therefore, the exponent of 10 should be 7 not 8.
The correct scientific notation = [tex] 7.645*10^7 [/tex]
2. 0.000327
We move the decimal point to our right by 4 decimal places. Since we are counting to our right, the exponent of 10 should be -4 not 4.
The correct scientific notation = [tex] 3.27*10^{-4} [/tex]
4. 116,000,000,000
Number of decimal places moved to our left = 11
The exponent of 10 should be 11 not 9.
The correct scientific notation = [tex] 1.16*10^11 [/tex]
5. 0.024
Number of decimal places moved to our right = 2
Since we are moving to our right, exponent of 10 = -2.
Calvin made a mistake here by not placing a decimal point in the first number after the last 0 to our right.
The correct scientific notation = [tex] 2.4*10^{-2} [/tex]
7. 100
There are just 2 zeros.
Therefore, the exponent of 10 = 2 not 3.
correct scientific notation = [tex] 10^2 [/tex]
9. 900,000
Number of decimal places moved to our left = 5
Since we are moving to the left, the exponent of 10 = 5 not -5
The correct scientific notation = [tex] 9*10^5 [/tex]
10. 0.00633
Number of decimal places moved to our right = 3
The exponent of 10 = -3
Calvin made a mistake by wrongly placing the decimal point.
The correct scientific notation = [tex] 6.33*10^{-3} [/tex]

Answer:

Step-by-step explanation:
You distribute the 2 into the parenthesis, so 2•5x=10x and 2•4=8. So now you have 10x+8=8. You want to get the x alone so you have to bring the 8 on the left side to the ride and you do that by subtracting 8 in both sides. So 10x+8(-8)=8(-8). That turns into 10x=0 because 8-8=0. and now you want to leave the x alone so you divide by 10 so 10x/10=0/10 and so the 10x/10=x and 0 divided by anything is zero. Therefore, x=0
The length of a rectangle is (x-8)units, and its width is (x+11) units. Which expression can represent the area of the rectangle?
Answer:
(x²+3x-88) square units
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
length of a rectangle is (x-8)units
Its width is (x+11) units.
Required
Expression for the area of the rectangle
Substituting the given function into the formula.
Area of the rectangle = (x-8)(x+11)
Area of the rectangle = x(x)+11x-8x-88
Area of the rectangle = x²+3x-88
Hence the expression that represents the area of the rectangle is x²+3x-88 units²
