What is meant by an expression?An equation is not the same as a mathematical expression. Expressions represent a group of integers, as opposed to equations, which represent a single number.
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.
The mathematical procedure for dividing large numbers into numerous smaller groups or parts is known as long division. The dividend is the number we divide into smaller groups, and the divisor is the number by which we divide. A problem can be solved by breaking it down into manageable steps.
Let the expression be (x³ - 5x² + 7x - 12) / (x-4)
[tex]$x^3-5 x^2+7 x-12=(x-4)\left(x^2-x+3\right)$[/tex]
simplifying the above equation, we get
[tex]$=\frac{(x-4)\left(x^2-x+3\right)}{x-4}$[/tex]
Cancel the common factor: x - 4
= x² - x + 3
Therefore, if the expression be (x³ - 5x² + 7x - 12) / (x-4) then the remaining exists x² - x + 3.

A car travels at a constant speed of 58 miles per hour. Which equation can be used to find m, the total number of miles the car travels, in h hours?
Answer:
58xH=M
Step-by-step explanation:
here is an example car traveles 58mph how many miles in 3 hours
58x3=174mph
The required equation that represents the number of miles the car traveled in h hours is m = 58h.
Given that,
A car travels at a constant speed of 58 miles per hour. Which equation can be used to find m, the total number of miles the car travels, in h hours is to be determined.
Distance is defined as the object traveling at a particular speed in time from one point to another.
Here,
As, per the question,
Distance = speed × time
From the given,
Distance = m
Speed = 58 mile / hour
Time = h (in hours)
So,
m = 58 × h
m = 58h
Thus, the required equation that represents the number of miles the car traveled in h hours is m = 58h.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = -3x - 2
4y = -12x - 8
Step 2: Solve for x
Substitute in y: 4(-3x - 2) = -12x - 8Distribute 4: -12x - 8 = -12x - 8Add 8 to both sides: -12x = -12xDivide both sides by -12: x = xHere we see that x does indeed equal to x. Therefore, x can be any value.
∴ The systems of equations have infinite amount of solutions.

Charlie has a giant bag of gumballs and wants to share them with his friends. He gives half of what he has to his buddy, Jaysen. He gives half of what's left after that to Marinda. Then he gives half of what's left now to Zack. His mom makes him give 5 gumballs to his sister. Now he has 10 gumballs left. How many gumballs did Charlie have to begin with?
Answer:
120 gumballs
Step-by-step explanation:
Let
x = total gumballs
Buddy = 1/2x
Balance = x - 1/2x
= 2x-x/2
= 1/2x
Miranda = 1/2 of 1/2x
= 1/2 × 1/2x
= 1/4x
Balance = 1/2x - 1/4x
= 2x-x/4
= 1/4x
Zack = 1/2 of 1/4x
= 1/2 × 1/4x
= 1/8x
Balance = 1/4x - 1/8x
= 2x-x/8
= 1/8x
His sister = 5
Balance = 1/8x -5
10 = 1/8x - 5
10 + 5 = 1/8x
15 = 1/8x
x = 15 ÷ 1/8
= 15 × 8/1
= 120
x = 120 gumballs

which function is equivalent to h(x)=10x^(2+9x-1)
Answer:
h(x) = (10x - 1)(x + 1)
Step-by-step explanation:
Given
h(x) = 10x²+9x-1
Required
Get its equivalent
To do this, we simply factorize h(x)
We have that:
h(x) = 10x²+9x-1
Expand
h(x) = 10x² + 10x - x - 1
Factorize
h(x) = 10x(x + 1) -1(x + 1)
This gives:
h(x) = (10x - 1)(x + 1)
Hence, the equivalent of h(x) = 10x²+9x-1 is h(x) = (10x - 1)(x + 1)
Answer: h(x) = (x+1) (10x-1)

A roller skating rink charges a flat rate of $5 to rent skates, plus $2.50 per hour to skate. You rent skates and skate for 3 hours. If you pay with a $20.00 bill, how much change do you get back?
Answer:
$7.50
Step-by-step explanation:
First, you multiply 3 and $2.50 (because you skate for 3 hours and it's $2.50 per HOUR to skate) 3 x 2.50 is $7.50 plus the flat rate of $5 is $12.50. So, your total altogether would be $12.50. So if you pay that total with $20, you have to subtract 12.50 from 20. 20 - 12.50 is $7.50. Your change will be $7.50. I hope this is correct! So sorry if it isn't!
Answer:
7.5
Step-by-step explanation:
First, you multiply 2.50 x 3. The answer to that is 7.50. Add on the renting skates, that is 12.50. Then, you subtract 12.50 from 20.00. The answer is 7.5.

What is Measurement unit?A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that;
A student spends $1.85 for a sandwich, $1.15 for a drink, $0.65 for a bag of chips, and $1.10 for two apples.
Now,
Since, A student spends $1.85 for a sandwich, $1.15 for a drink, $0.65 for a bag of chips, and $1.10 for two apples.
Hence, The amount of total money in dollars is,
⇒ $1.85 + $1.15 + $0.65 + $1.10
⇒ $4.75
We know that;
⇒ 1 dollar = 100 cents
Hence, we get;
⇒ 4.75 dollars = 4.75 × 100
= 475 cents
Thus, The student spends at lunch 4.75 dollars or 475 cents.

Is the relation shown in the arrow diagram a function? Justify your answer.
Answer:
NO
Step-by-step explanation:
For a relation to be a function, every input (x-value) must have exactly one output (y-value) mapped to it or related to it.
This means, in a function, an input value cannot give you two different outputs.
Therefore, relation shown in the arrow diagram IS NOT A FUNCTION, because one of the inputs (x-value), which is 1.2, has two different outputs (y-value) that is mapped or related to it, which are 6 and 8.
Tom the turkey is 2.5 feet tall and he casts a shadow that is 4 feet. The Thanksgiving Parade float version of Tom is 14 feet tall. How long is the shadow of the parade float?
Answer:
22.4 ft
Step-by-step explanation:
Given
[tex]Height = 2.5ft[/tex]
[tex]Shadow = 4ft[/tex]
Required
Determine the shadow of 14 ft Tom
The given parameters represents direct variation.
Let x represents the shadow of Tom.
So, we have:
When
[tex]2.5ft\ height = 4ft\ Shadow[/tex]
[tex]14ft\ height = x[/tex]
Cross Multiply:
[tex]2.5 * x = 14 * 4[/tex]
[tex]2.5 * x = 56[/tex]
Solve for x
[tex]x = 56/2.5[/tex]
[tex]x = 22.4[/tex]
Hence, the height of the shadow is 22.4ft

Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents? Why or why not?
Answer:
Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker
Step-by-step explanation:
Step one:
given data
cost of sneakers= $60
Required
the cost of the sneaker after the two discounts
Actually, the two percents given are the discount of the sale.
the first discount is
15%= 15/100*60
=0.15*60
=$9
The second is 10% coupon
10/100*60
=0.1*60
=$6
The total discounts = 9+6= $15
The cost of the sneakers= 60-15= $45

Step-by-step explanation:
The domain must not let 1/3 x + 2 go less than 0. So equate this binomial to 0 and then use the < or > symbol to indicate what the minimum value is.
1/3 x + 2 = 0 Subtract 2 from both sides
1/3 x = - 2 Multiply 3
3(1/3) x = - 2 * 3
x = - 6
So if x is less than - 6 the binomial will go negative and that is not a permitted value at this level.
So x must be - 6 or bigger.
Let's see what happens when x = - 6
1/3 ( - 6) + 2
-2 + 2
0
That's the minimum value for the domain.
Now try - 9
1/3(-9) + 2
- 3 + 2 = -1
That means you will have √-1 which does not exist in the rational world.
Now try x = 9
1/3 (9) + 2
3 + 2 = 5 which is fine.
So the answer you seek is x ≥ -6

Company B charges $10 plus an additional $2 per hour. The total price quote for each company is the same amount. How many hours do the companies estimate it will take to clean the pool?
Answer:
3 hoursStep-by-step explanation:
Step one:
given data
price quotes from Company A
charges= $7
additional charges per hour= $3
let the number of hours be x
and the total be y
the linear function for the total is
y=3x+7
price quotes from Company B
charges= $10
additional charges per hour= $2
let the number of hours be x
and the total be y
the linear function for the total is
y=2x+10
if the total quote is the same , then
3x+7=2x+10
solve for x, collect like terms
3x-2x=10-7
x=3 hours
