The required measure of the angle m∠B is 121°.

Given that,
Angle A and B are two vertical equal angles.
m∠B = 3x - 17
m∠A = 2x + 29

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
m∠A = m∠B
2x + 29 = 3x - 17
-x = - 46
x = 46

Now,
m∠B = 3  *46 - 17
m∠B =  138 - 17
m∠B = 121°

Thus, the required measure of the angle m∠B is 121°.

A) The reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

B) The reason why Susan had a higher retirement savings than bill is because Susan started investing 10 years earlier than bill and so her investment had a longer period to compound.

A) From the given exponential graph, we see that Chris curve was simialr to that of susan between ages 25 to 35 and suddenly Chris curve began to rise at a faster rate than that of Susan after that until when retired at 65 years of age.

Since we are told that chris continued that amount till retirement at 65, we are told that susan contributed the same amount for only that period between ages 25 and 35. Thus, it means that the reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

B) The reason why susan had a higher retirement savings than bill is because susan started investing 10 years earlier than bill and so her investment had a longer period to compound.

No, the picture frame will not fit into a box that measures 7.5 inches on each side because the side of the frame will be greater than it that is 7.54 inches.

Length of picture frame is given as:

= 7.54 inches

The length of Box is given as = 7.5 inches

From the above, we can see that the length of the box is smaller than the length of the picture frame.

So, the picture frame will not be able to fit in the box.

Therefore, we get that, the picture frame will not be able to fit into a box that measures 7.5 inches on each side because the side of the frame will be greater than it that is 7.54 inches.

By using the given graph, we can see that f(-5) = 3.

Here we have an image with the graph of the function y = f(x).

Remember that each point on that grid has the coordinates (x, y), where the values of x are on the horizontal axis, and the values of y are in the vertical axis.

So, if we want to find f(-5), then we want to see what value of y takes f(x) when x = -5.

So, first we need to go to the horizontal axis and find x = -5.

Once we find that value, now we need to move up or down along a vertical line (depending on where is the graph of the function). In this case we would move upwards. Now, count how many units we move up until we hit the graph of the function, that number of units will be the value of y.

In this case, we need to move 3 units upwards to hit the graph, then we have y = 3.

This means that the value of the function when x = -5 is y = 3, so we can write:

f(-5) = 3

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

In this problem we find a system of three linear equations with three variables, which can be resolved by several methods. In this case, we shall use the method of substitution. First, clear the variable x in the third equation:

x = 4 - 3 · y

Second, substitute x in the first two equations:

3 · (4 - 3 · y) + 2 · y - z = 8

12 - 9 · y + 2 · y - z = 8

- 7 · y - z = - 4

2 · (4 - 3 · y) + 2 · z = - 4

8 - 6 · y + 2 · z = - 4

- 6 · y + 2 · z = - 12

Third, clear z in the first equation derived in the previous step:

z = 4 - 7 · y

Fourth, substitute z in the second equation derived in the second step:

- 6 · y + 2 · (4 - 7 · y) = - 12

- 6 · y + 8 - 14 · y = - 12

- 20 · y = - 20

y = 1

Fifth, calculate y and x:

z = 4 - 7 · 1

z = - 3

x = 4 - 3 · 1

x = 1

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

Answer:

1. A U C = {a, b, c, d, e}

2. B intersect A = {a, b, d}

3. B' = {c, f, g, h}

4. A - (B intersect C') = {a,c}

Step-by-step explanation:

U is a big set with all the letters a through f in it. Set A, B, and C are subsets of U. They have some of the letters in them. You could pick out the contents of set A, for example, from set U. Same with B and C. There's a little bit of overlap between A and B and C.

So for #1, the U shaped symbol means "Union" and you can remember that because of the U shape symbol. "Union" means throw everything in all together. A U C means all of A and all of C all together. But you don't have to write repeats, just list the letters once.

A is {a,b, c, d} and C is {a, e} so A U C is all of both of them:

{a, b, c, d, e}

The upsidedown Usymbol is "intersect" and that is only what the two sets have in common (whats the same) between the two sets.

BintersectA is what is the same in B{b,e,a,d} and A{a,b,c,d}. They both have a, b and d so that is the answer to BintersectA = {a,b,d}

The "apostrophe" looking mark means "Not this set". So B' means NotB. You list everything that is NOT in B. B is {b,e,a,d} so B' is NotB = {c,f,g,h}

The last one has what looks like a minus sign. Thats like normal "takeaway" along with parenthesis, use that normally like grouping/"do this first" and also intersect and Not. So basically all the work, all in one problem.

C = {a,e} so C' is NotC is {b,c,d,f,g,h}

The BintersectC' is what are the same beween B and NotC:

BintersectC' = {b,d}

A take away {b,d}

would be

{a,b,c,d} - {b,d}

= {a,c}

By adding the number of cups needed for each cake, we conclude that you will need 25 cups of ingredients to make the 4 cakes.

We know that the recipe calls for:

That is for a single cake, so in a single cake you need a total of cups given by the sum of the above quantities, this gives:

(1 + 3/4) + (4 + 1/5) + 3/10 = (1 + 4) + (3/4 + 1/5 + 3/10)

= 5 + (3/4 + 2/10 + 3/10) = 5 + (3/4 + 5/10) = 5 + (3/4 + 1/2) = 5 + 5/4

= 5 + 4/4 + 1/4 = 6 + 1/4

Each cake needs (6 + 1/4) cups of ingredients, so 4 cakes will need:

4* (6 + 1/4) = 24 + 4/4 = 25
