Answer:

The equation that closely represents the graph is [tex]\mathbf{y=60x-160}[/tex]

Option A is correct.

Step-by-step explanation:

We need to find equation that represents the graph.

We can write equation in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

For finding the equation we need to find slope and y-intercept

Finding slope

The slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph we can find [tex]x_1=0, y_1=-160, x_2=1, y_2=-100[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-100-(-160)}{1-0} \\Slope=\frac{-100+160}{1}\\Slope=-100+160\\Slope=60[/tex]

We get Slope = 60

Finding y-intercept

Using point (0,-160) and slope m = 60, we can find y-intercept

[tex]y=mx+b\\-160=60(0)+b\\b+0=-160\\b=-160[/tex]

Writing the equation

So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:

[tex]y=mx+b\\y=60(x)+(-160)\\y=60x-160[/tex]

So, The equation that closely represents the graph is [tex]\mathbf{y=60x-160}[/tex]

Option A is correct.

Answer:

Point slope form

Step-by-step explanation:

Given

[tex]y - 6 = -4(x + 2)[/tex]

Required

Determine the form of linear equation

A linear has just three forms:

1. The slope intercept form.: This is always in form of [tex]y = mx + b[/tex]

2. The point slope form: This is always in form of [tex]y - y_1 = m(x - cx_1([/tex]

2. The standard form: This is always in form of [tex]Ax + Bxx = c[/tex]

By comparison, the three forms with the question, we can see that option B answers the question.

Answer:

16

Step-by-step explanation:

6 x 8 = 48

48 / 3 = 16

Rebecca can only wrap 16 packages with 6 yards of ribbon.

Answer:

Either, (9+√69)/6 or (9-√69)/6

Step wise:

3x²-9x+1=0-------------------(i)

comparing equation onw with (ax²+bx+c=0), we get,

a=3, b=-9, c=1

now,

using Quadratic Formula,

(-b±√b²-4ac)/2a=x

{-(-9)±√(-9)²-4.3.1}/2.3=x

(9±√81-12)/6=x

(9±√69)/6=x

Taking +(ve) sign                   Taking -(ve) sign

(9+√69)/6=0                           (9-√69)/6=0

∴(9+√69)/6=0                         ∴(9-√69)/6=0

[∵They cannot be further solved]

The solutions to the given quadratic equation are x = 2.884 and

x = 0.116.

The equation of the form ax² + bx +c is known as a quadratic equation.

The given equation is 3x² - 9x + 1 =0.

Solve the equation as follows:

3x² - 9x + 1 =0

Use the quadratic formula to solve the equation:

[tex]x = \frac{-(-9)\pm\sqrt{(-9)^2-4(3)(1)}}{2(3)}\\\\x= \frac{9\pm\sqrt{81-12}}{6}\\\\x=\frac{9\pm\sqrt{69}}{6}\\\\x = \frac{9\pm8.306}{6}\\\\x=\frac{9+8.306}{6}\quad\text{ or }x=\frac{9-8.306}{6}\\\\x=2.884\quad\text{ or }x=0.116[/tex]

Hence, the solutions to the given quadratic equation are x = 2.884 and

x = 0.116.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Total number of members in the relay team = 3 members

Total distance covered by the 3 members of the relay team = 3/8 miles

Now the equation will be ,

The distance ran by each member of the team =
Total distance covered by the 3 members of the relay team / Total number of members in the relay team

So , The distance ran by each member of the team = ( 3/8 ) / 3

                                                                                     = 3/8 x 1/3

                                                                                     = 1/8 miles

Therefore ,  the distance ran by each member of the team is 1/8 miles

And , taking the sum of each person's distance , we get

1/8 + 1/8 + 1/8 = 3/8

which is the total distance covered by the 3 members

Hence , The distance ran by each person in the relay team is 1/8 miles

Answer: 0.24, 3/8, 0.51, 0.517, 0.59, 3/4

Step-by-step explanation:

First you will have to convert the 3/4 and 3/8 to a decimal number. By doing this 3/4 turns into 0.75 and the 3/8 becomes 0.375. After this step you then arrange the numbers for the lowest of 0.24 then the 3/8 (0.375) next 0.51 after that is 0.517 then 0.59 and final after that 3/4

Answer:

1. x = 7

Step-by-step explanation:

12x + 16 = 100

12x = 84

x = 7

Answer:

1. x = 7

2. Simon and Iris earned $212 selling candy.

Step-by-step explanation:

1. 12(7) + 16 = 100

  84 + 16 = 100

  100 = 100

  Therefore, x = 7.

2. If they split the price by 2, then we need to multiply $100 by 2.

100 x 2 = $200

   $200 + $12 = $212

 Therefore, Simon and Iris earned $212 selling candy.

Honestly im confused by this but i think its the second one

Step-by-step explanation:

Answer:

x =  [tex]\frac{-6}{7+\sqrt{13}}[/tex]

r =  [tex]\frac{1+\sqrt{13} }{2}[/tex]

Step-by-step explanation:

In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-one number called the common ratio.

For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2.

-----

Let's take r=ratio of the geometric sequence

in first term, x is multiplied by  [tex]r^{0}[/tex]

First term:                   x [tex]r^{0}[/tex]

Second term: 4x+3 = x [tex]r^{1}[/tex]

Third term:     7x+3 = x [tex]r^{2}[/tex]

From the last 2 equation, we have to obtain r and x values.

Second equation - First equation:

3x = x r (r - 1)

Let's state: x different from 0, so we can simplify x, obtaining:

3 = [tex]r^{2}[/tex] - r

0 = [tex]r^{2}[/tex] - r - 3

r =  [tex]\frac{1+\sqrt{13} }{2}[/tex]  (only the positive value of r counts)

so, going to second term of the sequence:

4x+3 = x [tex]r^{1}[/tex] => x (4 - [tex]\frac{1+\sqrt{13} }{2}[/tex] ) = -3

x ([tex]\frac{7+\sqrt{13} }{2}[/tex] ) = -3  =>  x =  [tex]\frac{-6}{7+\sqrt{13}}[/tex]
