Answer:

17

Step-by-step explanation:

In this function, x = 5, so replace the x with 5 in the equation, multiply by 3, add 2, and 17 is the answer.

Answer:

[tex]f(x)=17[/tex]

Step-by-step explanation:

[tex]f\left(x\right)\:=\:3x\:+\:2;\:f\left(5\right)[/tex]

For f(x)=3x+2, substitute x with 5

[tex]f(x)=3(5)+2[/tex]

[tex]f(x)=17[/tex]

the answer is 18/18 which is the first one

Alright let's do this...

1. Five is less than a number and one = C.

2. Three times a number and five = F.

3. Five less than the sum of a number and two = B.

4. Two less than a number times two = A.

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.

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.

Answer:

b<16

Step-by-step explanation:

b/4<4. Multiply 4 on both sides. b has to be less than 16.

Answer:

9

Step-by-step explanation:

3x+8 = 35

3x = 27

x = 9

Hope this helps :)

Step-by-step explanation:

Here, (3x + 8)° and 35° are vertically opposite angles which are equal, therefore,

3x + 8 = 35

3x = 35 - 8

3x = 27

x = 27/3

x = 9

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.)

I am assuming the:

3 pennies = [tex]2^2[/tex]

If we observe the pattern, we see it on the  [tex]\rm n^t^h[/tex]  square the number of pennies will be [tex]\rm 2^n^-^1[/tex]

[tex]\rm n^t^h= 2^n^-^1[/tex]

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

Slope of the line x +2y =14 will be -1/2 since y = -1/2x+7, where m = -1/2 and c = 7.

Step-by-step explanation:

Answer:

2 Answers By Expert Tutors. Slope of the line x + 2y = 14 will be -1/2 since y = -1/2x+7, where m = -1/2 and c = 7. Now, the slope of the line perpendicular to this equation will be m_1 = -1/m = -1/ (-1/2) = 2.

Step-by-step explanation:

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 )

Step-by-step explanation:

A linear inequality resembles in form an equation, but with the equal sign replaced by an inequality symbol. The solution of a linear inequality is generally a range of values, rather than one specific value. Such inequalities arise naturally in problems involving words such as 'at least' or 'at most'.

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 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

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

= 5/3 × 5/6

= 25/18

= [tex]1\frac{7}{18}[/tex] ft²

Hence, 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

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.
