Graph the equation.
y-1=-2​(x-5​)

Answers

Answer 1

Step-by-step explanation:

y - 1 = -2(x - 5)

Distribute -2 into the parenthesis:

y - 1 = -2x + 10

Add 1 to both sides:

y - 1 + 1 = -2x + 10 + 1

y = -2x + 11 (This is the slope-intercept form where the slope, m = -2, and the y-intercept, b = 11).  

Using the slope (m = -2) and the coordinates of the y-intercept, (0, 11):

Plot the y-intercept on the graph. Then, use the slope's "rise over run" technique (2 units down, and 1 unit to the right) to plot other points.  Connect the points by drawing a line over them.

Attached is a screenshot of the graph that I created using the techniques provided in this post.

Answer:

–14d + 16 = –6d + 6 + 18

d = -1

Step-by-step explanation:

I used a calculator, pls let me know if im incorrect

Answer:

d = -1

Step-by-step explanation:

combine like terms

add the coefficients(numbers with variables) together and add the integers together.

-14 d + 16 = -6d + 6 + 18 ------ add 6d on both sides

-8d + 16 = 6 + 18 ---- subtract 16 on both sides

-8d = 18 - 16 + 6

-8d = 2 + 6

-8d = 8 --- divide -8 on both sides

d = -1

What is the x-intercept of the line with this equation?

−5x + [tex]\frac{1}{5}[/tex]y = 15

Answers

The x-intercept is the point on the graph where it crosses the x-axis. It’s also the value of the x-coordinate when y = 0.

To find the x-intercept, set y = 0:

-5x + 1/5(0) = 15

-5x + 0 = 15
-5x = 15

Divide both sides by -5:

x = -3.

Therefore, the x-intercept is (-3, 0).

A pharmacy claims that the average medication costs $32, but it could differ by as much as $8. Write an absolute value inequality to determine the range of medication costs at this pharmacy.

a
|x − 32| ≥ 8

b
|x − 8| ≥ 32

c
|x − 32| ≤ 8

d
|x − 8| ≤ 32

Answers

Step-by-step explanation:

So,

We can tell that the most expensive medication costs $40 and the cheapest costs $24.  Thus, only options A and C are left.

To see which inequality is true, test a value, such as $30, in the equation in option C.

|30 - 32| ≤ 8

|-2| ≤ 8

2 ≤ 8

Option C is correct.

What are congruence triangles?

If pairings of corresponding sides and corresponding angles are equal, two triangles are said to be congruent. They are the exact same size and form.

Consider triangles SQT and SRQ

Angle RSQ = Angle QST

Angle SRQ = Angle STQ  (90 degrees)

side SQ = side SQ (common)

By Angle Angle Side (AAS) property , both triangles are congruent.

Thus, Side RQ = Side QT

Substitute the values,

3x + 12 = 4x - 8

4x - 3x = 12 + 8

x = 20

Put x =20 in RQ

RQ = 3x + 12

     = 3×20 + 12

RQ = 72

Therefore, the Side of Triangle RQ = 72 units.

Darlene is buying a cake for her parent’s anniversary party. She has two to choose from. The cakes are similar prisms.

What is the ratio of the volumes of the smaller cake to the larger cake?

Select the correct response:

A. 8:27
B: 16:81

Answers

A.
explanation: to find the volume of both cakes we must multiply length•width•height

2•8•12=192
3•12•18=648
the simplest form of 192 to 648 is 8/27 therefor the answer ratio of small cakes to large cakes is A

let me know if i’m wrong

Ratio of the volumes of the smaller cake to the larger cake is A: 8 : 27.

What is Volume?

Volume of a three dimensional shape is the space occupied by the shape.

Given are two cakes in the form of a rectangular prism.

Volume of the rectangular prism = Length × Width × Height

Volume of the smaller cake = 12 × 8 × 2

                                              = 192 inches³

Volume of the larger cake = 18 × 12 × 3

                                            = 648 inches³

Ratio of volumes = 192 / 648

                            = 24 / 81 [Dividing by 8]

                            = 8 / 27 [Dividing by 3]

Hence the required ratio is 8 : 27.
