A x = -8
(B) x = -2
C x=3
(D) x = 12
Math

Answers

Answer 1
The answer is D.

The first step is to use the distributive property and turn 5(x-4) into 5x - 20.
You then move the twenty into the right equation by adding 20 to both sides. The final step is to move the 3x into the left equation by subtraction and then dividing both sides by 2 to isolate x. Hope this helped !!
Answer 2

Answer:

D

Step-by-step explanation:

5(x-4) = 3x + 4

5x-20 = 3x + 4

5x-3x-20= 4

2x=4 +20

2x=24

x=12

check answer by inserting 12 for x into original  equation.

5(12-4) = 3(12) +4

5(8) = 36 +4

40 = 40

what is the measure of the line segment AB if D is between A and B, AD = 7, and DB = 12?

Answers

Answer:

Given AD = 7 and DB = 12, to find AB you need to add them

AB = 12+7

AB = 19

The measure of the line segment AB is 19 units.

What are the coordinates of midpoint of the line segment AB?

Suppose we've two endpoints of a line segment as:

A(p,q), and B(m,n)

Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

[tex]x = \dfrac{p+m}{2}andy = \dfrac{q+n}{2}[/tex]

We are given that;

AD = 7, and DB = 12

Now,

To find the measure of the line segment AB, we need to use the segment addition postulate. The segment addition postulate states that if a point is between two other points on a line segment, then the sum of the lengths of the two smaller segments is equal to the length of the larger segment.

In this problem, D is between A and B, so we can apply the segment addition postulate and write:

AD + DB = AB

Substituting the given values of AD and DB, we get:

7 + 12 = AB

Simplifying, we get:

19 = AB

Therefore, by the given point the answer will be 19 units.

Step-by-step explanation:

15+26=41

Answer:

41 minutes

Step-by-step explanation:

If she jogged 15 minutes more on Sunday than Saturday, we can find how many minutes she jogged on Sunday by adding 15 to Saturday's amount:

So, add 15 to 26:

15 + 26

= 41

Use the zero product property to find the solutions to the equation x2 + 12 = 7x.

Answers

Are u solving for x? And is the “x2” x to the power of 2 or is it 2x
x = 3 or x = 4

Given
x² + 12 = 7x ( subtract 7x from both sides )
x² - 7x + 12 = 0 ← in standard form
(x - 3)(x - 4) = 0 ← in factored form
Equate each factor to zero ( zero product property ) and solve for x
x - 3 = 0 ⇒ x = 3
x - 4 = 0 ⇒ x = 4

Mario deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Mario leaves the money in the account for 12 years, how much interest will he earn?

Answers

Answer:

$2,184

Step-by-step explanation:

Simple interest = (Principal × Rate × Time) / 100

Principal = $6,500

Rate = 2.8%

Time = 12 years

Simple interest = (Principal × Rate × Time) / 100

= (6,500 × 2.8 × 12) / 100

= 218,400 / 100

= 2,184

Simple interest = $2,184

The simple interest on $6,500 at 2.8% for 12 years is $2,184

What is the slope of the line parallel to 7x + 4y = -16?

Answers

Answer:

The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

Step-by-step explanation:

Parallel lines have the same slopes and different y-intercepts

The slope of the line who has an equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]

Let us use these rules to solve the question

∵ The equation of a given line is 7x + 4y = -16

→ Compare it with the form of the equation above

∴ a = 7 and b = 4

∵ The slope of the line = [tex]\frac{-a}{b}[/tex]

∴ The slope of the line = [tex]\frac{-7}{4}[/tex]

∵ Parallel lines have the same slope

The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

1. (MGSE9-12.F.BF.1) This table shows the number of people at a festival at certain times during
the day. Which function best represents the table below?
Hour (PM) 1 2 4 7 8
Number of People 12 19 33 54 61
A. f(x) = 7x + 12
B. f(x) = 7x + 5
C. f(x) = 5x + 7
D. f(x) = 5x + 12

Answers

Answer:

[tex] f(x) = 7x + 5 [/tex].

Step-by-step explanation:

The equation that represents the function can be written in the slope-intercept form, [tex] f(x) = mx + b [/tex].

To create an equation, we need to find the slope (m) and the y-intercept (b) of the function.

First, calculate the slope of the function using two points, (1, 12) and (2, 19).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{19 - 12}{2 - 1} = \frac{7}{1} = 7 [/tex]

Next, find b by substituting x = 1, f(x) = 12, and m = 7 into [tex] f(x) = mx + b [/tex].

[tex] 12 = (7)(1) + b [/tex]

[tex] 12 = 7 + b [/tex]

Subtract 7 from each side

[tex] 12 - 7 = b [/tex]

[tex] 5 = b [/tex]

[tex] b = 5 [/tex]

Substitute m = 7 and b = 5 into [tex] f(x) = mx + b [/tex].

✅Thus, the equation that represents the function would be:

[tex] f(x) = 7x + 5 [/tex].
