Answer:

x = 2

Step-by-step explanation:

3x+4y=36

Y=-1/2+8

Now we substitute y with -1/2+8.

3x + 4(-1/2+8) = 36

3x + 4(7.5) = 36

3x + 30 = 36

3x = 6

Rotation only changes the position of the image, not the size. :)

Answer:

C. They were rotated around the origin since that is the only point in the plane you can use as the center of rotation.

explanation:

when you think about it and look at the other problems, they are all going around the center of the grid when rotated, specifically the key word is when rotated, when they are translated they go anywhere they want.

14/23

Step-by-step explanation:

There are 253 tokens in all. Since 77 are blue and 77 are green, the probability of selecting either a blue token or a green token is 154/253, which reduces to 14/23.

The value of the equivalent equation will be 32=3x+8

Answer: B

Step-by-step explanation:

These are vertical angles, so x+97=2x+32, meaning x=65.

So, the measure of angle 1 = 65 + 97 = 162 degrees

The value of m∠1, given that m∠1 = x + 97 and m∠2 = 2x + 32 is 162° (2nd option)

First, we shall list out the given parameters from the question. This is given below:

Next, we shall obtain the value of x. Details below:

m∠1 = m∠2 (vertically opposite angle)

x + 97 = 2x + 32

Solving for x, we have:

97 - 32 = 2x - x

65 = x

Thus,

x = 65

Now, we shall obtain the value of m∠1 as follow:

m∠1 = x + 97

x = 65

Therefore,

m∠1 = 65 + 97

= 162°

Thus, the value of m∠1 is 162° (2nd option)

Answer:

  B

Step-by-step explanation:

The first step of any problem solution is look at the given information. Here, we are given the equation of a line in (almost) standard form, and we want to match the equation with a graph. We notice that the coefficients of the variables are factors of the constant, so the intercepts are integer values easily found.

We can compare the line's intercepts to those shown on the graphs to choose the correct graph.

x-intercept

The x-intercept is found by setting y=0 and solving for x:

  -3x +5(0) = -15

  x = -15/-3 = 5

Only one graph shows a line with an x-intercept of (5, 0): graph B.

y-intercept

We can confirm graph B by finding the y-intercept. For this, we set x=0 and solve for y.

  -3(0) +5y = -15

  y = -15/5 = -3

Graph B also has a y-intercept of (0, -3), confirming it is the correct choice.

_____

Additional comment

Part of "look at the given information" is "look at the answer choices." What you look for is what makes one choice different from the others. Here, the lines have x- and y-intercepts of ±3 and ±5. The y-intercepts are the same for graphs A and B, and for graphs C and D.

However, the x-intercepts are different for all of them. This tells you that finding the x-intercept is the fastest way to find the correct graph.

Answer:

6468 mm²

Step-by-step explanation:

Given:

Therefore, the area of the small rectangle is:

= width × length

= 21 × y

= 21y mm²

From inspection of the larger rectangle

Therefore, the area of the larger rectangle is:

= width × length

= 84(2y + 21)

= 168y + 1764 mm²

We know that the area of the larger rectangle is 11 times the area of the smaller rectangle. Therefore,

⇒ 11 small rectangles = larger rectangle

⇒ 11(21y) = 168y + 1764

⇒ 231y = 168y + 1764

⇒ 63y = 1764

⇒ y = 28

Therefore, the missing side length of the smaller rectangle is 28 mm.

Finally, to find the area of the larger rectangle, substitute the found value of y into the found expression for its area:

⇒ area = 168y + 1764

⇒ area = 168(28) + 1764

⇒ area = 4704 + 1764

⇒ area = 6468 mm²

One coffee maker's cost in 1983 was $20.85 if the current CPI is 153 option (a) is correct.

It is given that the CPI is currently 153 if a coffee maker costs $31.90 today. It is required to find how much did one cost in 1983.

It is defined as the tool to measure inflation that indicates between two periods how much cost is increased. It can be represented by [tex]\rm CPI_t[/tex] for the given time 't'

The formula for finding the CPI:

[tex]\rm CPI_t = \frac{C_t}{C_0}\times 100[/tex]

Where [tex]\rm c_t[/tex] is the cost in the current market

           [tex]c_0[/tex] is the cost at the given period.

We have in the question:

[tex]\rm c_t = \$31.90\\\\\rm CPI_t = 153[/tex]

Putting these values in the CPI formula, we get:

[tex]\rm 153= \frac{31.90}{C_0}\times 100\\\\\rm c_0 = \frac{3190}{153} \\\\\rm c_0 = \$20.84 \approx \$20.85[/tex]

Thus, one coffee maker's cost in 1983 was $20.85 if the current CPI is 153.
