The diagram shown relates age with mileage, so to get the mileage at any age,

we trace the age in years to the line of best fit and;

trace horizontally to cut the vertical axis and obtain the overall mileage.

Doing this, we get;

We observe that the overall mileage according to the line is;

Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the
bagirrra123 [75]

Answer:

c = -6

d = -1

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

a = (3,5) --- Point on A

a' = (-3,-6) --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

(x,y) \to (x,-y)

So, we have:

(3,5) \to (3,-5)

Next, is to calculate the translation from (3,-5) to (-3,-6)

This is calculated using:

3 + c = -3

and

-5 + d = -6

So, we have:

3 + c = -3

c = -3-3

---- i.e. Shift by 6 units to the left

-5 + d = -6

d = 5 - 6

d = -1  --- i.e. Shift by 1 unit down

write an expression to describe a rule for the sequence. Then find the 100th term in the sequence 3, 10, 17, 24, 31, 38, ...
blagie [28]
As we can tell, the first number is 3, so we'll have a y-intercept in our equation and overall. Secondly, we can tell it's increasing by 7 each time, so we can tell that's the rate. But, it won't just be 3+7x, if we plug 1 in, it would be 10 and not 3. We need to put in the parenthesis 3+7(x-1). If we put one in, we would receive three. Let's make sure this works.
3+7(5-1)
3+7(4)
3+28
31
31 is the fifth terms.
So the expression would be 3+7(x-1).
Let's find the 100th term.
3+7(100-1)
3+7(99)
3+693
696
So the 100th term would be 696.

How would I solve this equation? I also would like the steps please.
bagirrra123 [75]

Answer:

The answer to your question is x = 23.36

Step-by-step explanation:

                                          \frac{1250}{1.04^{x} } = 500

Solve for x

                                          1250 = 500(1.04)^{x}

                                          \frac{1250}{500} = 1.04^{x}

Apply logarithms

                                          2.5 = 1.04^{x}

                                          log 2.5 = x log 1.04

                                         x = 0.398 / 0.017

                                        x = 23.36

Solve Each Equation<br><br> 5. -8(5+4x)=-232<br><br> 6. -84=4(4r+7)
Sever21 [200]

Step-by-step explanation:

<h2>5.</h2>

- 8(5 + 4x) =  - 232

- 40 - 32x =  - 232 \\  - 32x =  - 232 + 40 \\  - 32x =  - 192 \\  \frac{ - 32x}{ - 32}  =  \frac{ - 192}{ - 32}  \\  \\ \huge x = 6

<h2>6.</h2>

- 84 =  4(4r + 7) \\  - 84  =  16r + 28 \\ 16r =  - 84 - 28 \\ 16r =  - 112 \\  \frac{16r}{16}  =  -  \frac{112}{16}  \\  \\  \huge r = 7

Hope this helps you

ASAP, NEED HELP ASAP
Ivanshal [37]

Answer:

OPTION C

Step-by-step explanation:

If SOLUTION A has 4 cups then SOLUTION B has 2. If SOLUTION A has 8 then SOLUTION B has 4.

Note that for every 2 cups of Solution A, we have 1 cup of Solution B.

So, OPTION A is incorrect.

If there are 4 cups of Solution A, then there are 4 + 2 cups in total.

That means the ratio of cups of SOLUTION  A to the total number of cups is:

4 : 6 = 2 : 3

Similarly, 8 : 12 = 2 : 3

And, 12 : 18 = 2 : 3

And, 16 : 24 = 2 : 3

So, we see that the ratio is 2 : 3.

Therefore, OPTION C is the correct answer.
