A. 3/7
B. 21
C. 23 1/8
D. 37 3/7

Answers

24=7/8g
get rid of fractions
multiply both sides by 8
192=7g
divide both sides by 7
192/7=g
aprox
27 and 3/7
none of the answers are correct unless you typed 37 instead of 27

multiply both sides by 8
so 192 = 7 g
then divide both sides by 7
so g = 192/7 = 27 3/7

Solve for x: 3 < x + 3 < 66 < x < 9
6 > x > 9
0 < x < 3
0 > x > 3

Answers

Answer:

C. 0 < x < 3

Step-by-step explanation:

Given:

3 < x + 3 < 6

Substract 3 from each side:

3 - 3 < x + 3 - 3 < 6 - 3
0 < x < 3

Correct choice is C

3<x+3<6

Subtract 3

3-3<x<6-3
0<x<3

Option C

Factor this expression. Check by multiplying factors. 3ab+a+3b^2+b
whats the answer

Answers

The solution to the problem is as follows:

you have"a" as common so, you can write it as: a(3b+1) +3b^2 + b. from the remaining two terms, you have b common, so write it as a(3b+1) +b(3b+1).

This gives you (a+b)(3b+1)

Find the coordinates of C' after a reflection across the liney = 1 and then x = 2. Write in the form (a,b)
Part 5a

Answers

Answer: (4,2)

==============================================================

Explanation:

C is at (0,0). Ignore the other points.

Reflecting over y = 1 lands the point on (0,2) because we move 1 unit up to arrive at the line of reflection, and then we keep going one more unit (same direction) to complete the full reflection transformation. I'll call this point P.

Then we reflect point P over the line x = 2 to arrive at the location Q = (4,2). Note how we moved 2 units to the right to get to the line of reflection, and then keep moving the same direction 2 more units, then we have applied the operation of "reflect over the line x = 2"

So we have started at C = (0,0), moved to P = (0,2) and then finally arrived at the destination Q = (4,2). This is the location of C' as well.

All of this is shown in the diagram below.

(09.02 HC)The function f(x) = −x2 + 50x − 264 models the profit, in dollars, a yoga studio makes for selling monthly memberships, where x is the number of memberships sold and f(x) is the amount of profit.
Part A: Determine the vertex. What does this calculation mean in the context of the problem? (5 points)

Part B: Determine the x-intercepts. What do these values mean in the context of the problem?

Answers

We factor the equation to get:

-(x-25)^2+361

In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361). This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.

B. The x-intercepts are the values of x for which f(x) is 0. This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44. Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.

Answer:

x = 6, x = 44; The zeros represent the number of monthly memberships when no profit is made.

I took the quiz and got it right.

Out of 1,100 discs tested, 13 are defective. Estimate the number of defective discs in a batch of 41,000.

Answers

This is a simple proportion

1100 : 13 = 41000 : x

For every 1100 discs, 13 are defective, meaning that there will be an X number for each 41000

13 * 41000 = 1100 * x

13 * 410 = 11 * x
5330 = 11 * x
x = 5330/11
x = 484.5

That means that for every 41000, approximately 485 discs will break down.

Answer:

x = 484.5

That means that for every 41000, approximately 485 discs will break down
