what is the coefficient in the expression below 2x-8
Answer:
2x - 8
Parts of an equation:
2 - coefficient
x - variable
8 - constant
The number 2 is not a coefficient in the expression. FALSE.
The expression has three terms. FALSE. two terms only: 2x & 8
The variable in the expression is x. TRUE
The number 2 is a constant in the expression. FALSE
The expression has one variable term. FALSE. 2x is term but it's a combination of a number and a letter. Variable term is letter only.
Hello.
The coefficient is the number before a variable (letter)
The constant is also a number.
What's the difference between a constant and a coefficient?
Well, a coefficient is always before a variable, and a constant is just a number (without any variables next to it)
In this case, the variable is x, the number before x is 2, and 8 is the constant.
Therefore, 2 is the coefficient in this expression.
I hope it helps.
Have a nice day.

Answer:
width = 9/2 inches, length = 18 inches
Step-by-step explanation:
Step-by-step explanation:
l = length
w = width
l×w = 81 in²
l = 2w + 9
we can use the identity of the second equation in the first equation :
(2w + 9)×w = 81
2w² + 9w = 81
2w² + 9w - 81 = 0
the general solution to such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = w
a = 2
b = 9
c = -81
w = (-9 ± sqrt(9² - 4×2×-81))/(2×2) =
= (-9 ± sqrt(81 + 648))/4 =
= (-9 ± sqrt(729))/4 = (-9 ± 27)/4
w1 = (-9 + 27)/4 = 18/4 = 9/2 in
w2 = (-9 - 27)/4 = -36/4 = -9
a negative solution for a side length does not make any sense, so, width = 9/2 in is the only valid solution.
l = 2w + 9 = 2×9/2 + 9 = 9+9 = 18 in
so, the last answer option is correct.

Step-by-step explanation:
Solve for the value of r.
(6r-7)
55°
Answer:
r=7
Step-by-step explanation:
6r-7+90+55=180
6r+138=180 ----- 6r=180-138
6r=42 ----- divide both sides by 6
r=7
(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)

Answer:
72 sq ft
Step-by-step explanation:
A square room means ecah side is equal. so 12*12= 144.
12 times 6 (for the height)= 72 sq ft
Answer:
72 square feet
Step-by-step explanation:
if the area of the floor is 144 and square, that means that the sides are the same length. 12 * 12 = 144 so the length is 12.
the height of the room is 6 so you multiply 12 and 6 and you get 72

-7 x A = -14 Fill in the missing number in the equation
Answer:2
Step-by-step explanation:
You need to remember these 3 rules when working with multiplication:
Negative number x Negative number = positive number
Negative number x Positive number = Negative number
Positive Number x Positive Number = Positive Number
With that in mind, we see in this equation we are multiplying negative number x positive number = negative number
And we also know 7*2=14 so we know A = 2 and we also know (since A is a positive number) 2 will be postitive:
So the equation will look like this:
-7 x 2 = -14
Therefore A = 2

Answer:
Given,
Area of the Square = ( x² - 10x + 25 ) m²
We have to find: Length of the side of the square.
Let s be the side of square.
We find length of side of the by using factorization.
According to the question,
s² = x² - 10x + 25
s² = x² - 5x - 5x + 25
s² = x( x - 5 ) - 5( x - 5 )
s² = ( x - 5 )( x - 5 )
s² = ( x - 5 )²
Taking square root on both sides we get,
s = x - 5
Therefore, Expression that represents the length of one side of the square is x - 5.

the measure of one interior angle of a triangle is 45°. What can you conclude about the other two interior angles of the triangle?
One of the other angles must be a right angle.
The sum of the measures of the other two angles is 135°.
The other two angles must be acute angles.
One of the other angles must have a measure greater than 90°.
Answer:
The sum of the measures of the other two angles is 135°.
Step-by-step explanation:
The sum of the interior angles of a triangle will add up to 180°. So by subtracting 45° from 180°, the other two angles have to add up to 135°.
Answer:
The sum of the measures of the other two angles is 135° or b

Solve the system of equations using subtraction.
2x−4y=−4
2x+ y =11
Answer:
(4, 3 )
Step-by-step explanation:
2x - 4y = - 4 → (1)
2x + y = 11 → (2)
subtract (2) from (1) term by term to eliminate x
(2x - 2x) + (- 4y - y) = - 4 - 11
0 - 5y = - 15
- 5y = - 15 ( divide both sides by - 5 )
y = 3
substitute y = 3 into either of the 2 equations and solve for x
substituting into (2)
2x + 3 = 11 ( subtract 3 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
solution is (4, 3 )

Answer:
9
Step-by-step explanation:
3x+8 = 35
3x = 27

3x = 27
x = 27/3

Hope it helps you!!What will be the total cost of Maria's ARM if the term of the loan were 25 or 20 years instead of 30? Use the variable rate loan calculator to find the answers. Write them in the spaces below.
Mortgage Term | Total Cost
25 years: |
20 years: |
Answer:
The total cost of the loan goes down as the term decreases. Although the amount of the loan itself remains the same, the total amount of interest Maria would have to pay in interest decreased when the term of the loan decreased. However, the monthly payments increased when the term decreased. So, a shorter term saves interest but requires greater monthly payments.

Which of the following could be the side lengths of a right triangle?
Answer:
To have a right triangle, the side lengths should make Pythagorean theorem true
Since the hypotenuse is always the longest side of a triangle, the biggest number will be c
Set the rest two numbers as a and b
Use a^2 + b^2 = c^2 to plug in the numbers
If you get true equation, meaning you have the same number on the left and right sides of equation, then it is going to create a right triangle

Step-by-step explanation:
The area of the rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide is [tex]1\frac{7}{18}[/tex] ft²
What is area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given that, Jackie bought a rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide.
We need to find its area,
We know that, the area of the rectangle = length × width
Here,
Length = 5/6 ft
Width = [tex]1\frac{2}{3}[/tex] ft
Area = [tex]1\frac{2}{3}[/tex] × 5/6
