Answer:

6y = -17x + 17

Step-by-step explanation:

All you have to do for this equation to put it into slope-intercept form is to minus 17x from both sides giving you 6y = -17x + 17 which is the correct form. Then you can simplify by dividing everything by 6 but I'll let you do that.

The equation which shows the correct use of the distributive property is - 6x + 2 = -15

Given:

-4(3/2x - 1/2) = -15

multiply separately

-4(3/2x) -4(-1/2) = -15

-12/2x + 4/2 = -15

- 6x + 2 = -15

solve for x

-6x = -15 - 2

-6x = -17

x = -17/-6

x = 2.83

Therefore, the equation which shows the correct use of the distributive property is

- 6x + 2 = -15

Answer:

[tex]1\frac{1}{2}x + 4[/tex]

Step-by-step explanation:

We are given the Perimeter: P = Perimeter[tex]3\frac{1}{2}x + 18[/tex]    in decimal 3.5x+18

we know that a Perimeter is equal to all sides added up: S1+S2+S3+S4=P

we know that this is a rectangle so that means that it has 4 sides and two sides are the same and the other 2 are the same.

We are given the the height on the image

Height: H = [tex]\frac{1}{4}x + 5[/tex]  in decimal 0.25x + 5

That height is one side so we know another of the sides is the same.

Perimeter is equal to all sides added up. So we have to subtract the sides to find out each ones measurements.

(Height x 2) + (Width x 2) = Perimeter

Therefore we know the height which is given on the image is 0.25x+5 so that times 2 = 0.5x+10    (height x 2)

so now we can subtract the heights from the perimeter.

  3.5x  +  18

-  0.5x  +  10

--------------------

  3x     +    8

So we got rid of both heights. Now we are left with our two lengths:

3x+8  = (length x 2)

To get the length of one side we divide that by 2 because there are 2 sides that have the same length and get 1.5x+4  in fractions that is:

  [tex]1\frac{1}{2}x + 4[/tex]

Answer:

Ramon can make 3 1/2 or 3.5 servings of 1/4 of a cup each one

Step-by-step explanation:

1. What information was given to us to answer the question correctly?

Amount of cottage cheese Ramon has = 7/8 of a cup

2. How many 1/4 cup servings can he make?

For answering this question, we make this calculation:

7/8 * 1/4

7/8 * 4/1 = 28/8 = 7/2 or 3 1/2 cup servings

This means that Ramon can make 3 1/2 or 3.5 servings of 1/4 of a cup each one:

1/4 + 1/4 + 1/4 + (1/2 * 1/4) = 7/8

3/4 + (1/2 * 1/4) = 7/8

3/4 + 1/8 = 7/8

6/8 + 1/8 = 7/8

7/8 = 7/8

Answer:

[tex]57.2\ ft[/tex]

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem

The tangent of angle of 5 degrees is equal to the quotient of "rise over run"

Let

y ----> the rise of the ramp

x ----> the run of the ramp

[tex]tan(5^o)=\frac{y}{x}[/tex]

we have

[tex]y=5\ ft[/tex]

substitute and solve for x

[tex]tan(5^o)=\frac{5}{x}[/tex]

[tex]x=\frac{5}{tan(5^o)}[/tex]

Answer:

Divide 2 by 1/6 and you should get the value of x.

Step-by-step explanation:

simple 2 step equation.

Answer: x = 12

Step-by-step explanation: In this equation, notice that x is being multiplied by a fraction. In this situation, in order to get x by itself, we must multiply both sides of the equation by the reciprocal of that fraction. The reciprocal of a fraction is just that fraction flipped so the reciprocal of 1/6 is just 6/1.

So here, in order to get x by itself, we multiply both sides of the equation by 6/1. On the left our 6's cancel and our 1's cancel and we're left with x. On the right we have 2 x 6 which simplifies to 12 so x = 12.

Answer:

122 degree

Step-by-step explanation:

As we know that

Sum of all angles of triangle = 180 degree

Angle A + Angle B + Angle C = 180

Angle A + 43 + 15 = 180

Angle A + 58 = 180

Angle A = 180-58

Angle A = 122

Answer:

<AFB

Step-by-step explanation:

Supplementary angles are the angles that's sum up to 180° which is called a straight angle.

In this question we see AFB is supplementary to DFA for DFB is the straight angle.

The equation of a line is y = mx + b  [m is the slope, b is the y-intercept or the y value when x = 0  ---->  (0, y) or the point where the line goes through the y-axis]

To find the slope, you use the slope formula (m):

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]           and plug in 2 points

I will use the points (0, 0) and (1, 8)

(0, 0)  ---->  (x₁, y₁)

(1, 8) ---->   (x₂, y₂)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{8-0}{1-0}[/tex]

m = 8

Since you know m, plug it into the equation.

y = 8x + b

The graph shows that the y-intercept is 0, so plug it into the equation

y = 8x    

When y is equal to -6, the evaluation of the formula [tex]y^2 + 7y - 5[/tex] is -11.

In order to assess this mathematical statement when y=-6, we substitute -6 for y in the expression y² + 7y - 5.

This evaluation's outcome is a score of -11.

For, "x" greater than 34, the perimeter of the picture frame greater than 152 inches

Solution:

Let "x" be the width of the frame

Given that, The length of a picture frame is 8 inches more than the width

Therefore,

Length = width + 8

Length = x + 8

The perimeter of rectangle is given by formula:

Perimeter = 2(length + width)

Substituting the values we get,

Perimeter = 2(x + 8 + x)

Perimeter = 2(2x + 8)

Perimeter = 4x + 16

The perimeter of the picture frame greater than 152 inches

Perimeter > 152

[tex]4x + 16>152\\\\\text{Subtract 16 from both sides of inequality}\\\\4x + 16 - 16 > 152 - 16\\\\4x>136\\\\\text{Divide both sides by 4}\\\\x>34[/tex]

a)

During week 0, the number of specialty items produced at the old factory than at the new factory is 33

b)

Old factory

The growth rate from week 0 to week 1 is 20.

The growth rate from week 1 to week 2 is 22.

New factory:

The growth rate from week 0 to week 1 is 30.

The growth rate from week 1 to week 2 is 32.

c)

The weekly number of specialty items produced at the new factory exceeds the weekly number of specialty items produced at the old factory

in week 4.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Old factory:

f(x) = 223 (1.09)^x

When x = 0,

f(0) = 223(1.09)^0 = 223(1) = 223

In zero weeks, the number of specialties produced is 223.

When x = 1,

f(1) = 223(1.09)^1 = 243.07 = 243

When x = 2,

f(2) = 223(1.09)^2 = 265.32 = 265

When x = 3,

f(3) = 223(1.09)^3 = 290.41 = 290

When x = 4:

f(4) = 223(1.09)^4 = 318.53 = 318

New factory:

(0, 190), (1, 220), (2, 252), (3, 290), (4, 337)

This means,

(0, 190)

In zero weeks, the number of specialties produced is 190.

Thus,

a)

During week 0, the number of specialty items produced at the old factory than at the new factory.

= 223 - 190

= 33

b)

The growth rates in the weekly number of specialty items produced at each factory.

Old factory:

The growth rate from week 0 to week 1 = (243 - 223)/(1 - 0) = 20/1 = 20

The growth rate from week 1 to week 2 = (265 - 243)/(2 - 1) = 22/1 = 22

New factory:

The growth rate from week 0 to week 1 = (220 - 190)/(1 - 0) = 30/1 = 30

The growth rate from week 1 to week 2 = (252 - 220)/(2 - 1) = 32/1 = 32

c)

The weekly number of specialty items produced at the new factory exceeds the weekly number of specialty items produced at the old factory

in week 4.

i.e

f(4) = 223(1.09)^4 = 318.53 = 318

318 < 337

Answer:

A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.

Total distance covered by the man in terms of 'x' = (12.5x-285)miles

Step-by-step explanation:

Given:

Speed of  a man = 'x' miles/hour

Time taken = [tex]3[/tex] hour

So, distance = product of speed and time.

Distance covered in term of 'x' [tex]=(d_1=3x)[/tex]

Now,

Speed = [tex](2x-60)[/tex] miles/hour

Time taken= [tex]4.75[/tex] hours

Distance [tex](d_2)[/tex]  = [tex](2x-60)\times 4.75[/tex]

                      = [tex](2x\times 4.75) -(60\times 4.75)[/tex]

                      = [tex](9.5x - 285)[/tex] miles

Total distance covered by the man = Summation of  [tex]d_1[/tex] and [tex]d_2[/tex]

                                                           = [tex](9.5x-285+3x)[/tex]

                                                           = [tex](12.5x-285)[/tex] miles

So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.
