Step-by-step explanation:

I went through all of them and also checked what you did.

1. no, wrong. I don't know how you got to the 2×7 in there.

17 - 5×4/2 = 17 - 5×2 = 17 - 10 = 7

2. we just did in the other question. it is 26.

3. correct for the approach, but mistake in the final calculation : 28 + 64 = 92 !

4. (4-7)² - 6×7 + 20

how did you get to the 26 for -6×7 + 20 ?

no.

-3² - 42 + 20 = 9 - 42 + 20 = -13

5. 2×(18 - (5 + 3²)/7)

2×(18 - (5 + 9)/7) = 2×(18 - 14/7) = 2×(18 - 2) = 36 - 4 = 32

6. ((-5 + 1)/2)³ - |‐7|

that may part means "absolute value" of -7. and you know, that means 7.

(-4/2)³ - 7 = -2³ - 7 = -8 - 7 = -15

7. 1 + (-2 - 5)² + (14-17)×4

1 + -7² + -3×4 = 1 + 49 - 12 = 38

8. (6×(2+4) - 1) / (2×3 + 1)

(6×6 -1) / (6 + 1) = 35 / 7 = 5

9. (2⁵/8 + 3) / (4 + 3)

(32/8 + 3) / (7) = (4 + 3) / 7 = 7/7 = 1

10. (17×5 - 3×5) / (3² + 1)

(14×5) / (9 + 1) (as for same factors we can contract the expressions like 17×5 - 3×5 = 14×5)

70 / 10 = 7

11. (13 + 7²/7) / (9 - 20/4 - 16)

(13 + 49/7) / (9 - 5 - 16) = (13 + 7) / (-12) = 20/-12 = -5/3

12. - |-16| / ((3² - 4) / (5 - 10))

-16 / ((9-4) / (-5)) = -16 / (5/-5) = -16 / -1 = 16

Answer:

0

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 7-7)/(5-8)

    = 0/-3

   = 0

Answer:

X = All Real Numbers

Step-by-step explanation:

Distribute: (6)(x) + (6)(−6) + x = (7)(x) + (7)(−7) +13

Multiply: 6x + −36 + x = 7x + −49 + 13

Combine like terms: (6x + x ) + (−36) = (7x) + (−49 + 13)

Simplify: 7x + −36 = 7x + −36

7x − 36 = 7x −36

Subtract 7 from both sides: -36 = -36

Add 36 to both sides: 0 = 0

Answer:

constant linear function because it is a straight line with no endpionts, therefore it is CONSTANT

Step-by-step explanation:

Answer:

Part A. Option a. is correct

Part B. Option a. is correct.

Step-by-step explanation:

Part A.  

The numbers given by 2k + 9, 2k + 11, 2k + 13 will represent 11, 13 and 15 for k = 1, which are consecutive odd integers.

And the numbers given by 3k + 2, 3k + 3 and 3k + 4 will represent 5, 6, and 7 for k = 1 and they are not consecutive odd integers.

Therefore, option a is correct.

Part B.  

The numbers given by k + 1, k + 2, k + 3 will represent 2, 3 and 4 for k = 1, which are consecutive integers.

And the numbers given by k + 6, k + 8, and k + 10 will give 7, 9, and 11 for k = 1 and they are not consecutive integers.

Therefore, option A is correct.

Answer:

Anything in the form x = pi+k*pi, for any integer k

These are not removable discontinuities.

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

Explanation:

Recall that tan(x) = sin(x)/cos(x).

The discontinuities occur whenever cos(x) is equal to zero.

Solving cos(x) = 0 will yield the locations when we have discontinuities.

This all applies to tan(x), but we want to work with tan(x/2) instead.

Simply replace x with x/2 and solve for x like so

cos(x/2) = 0

x/2 = arccos(0)

x/2 = (pi/2) + 2pi*k or x/2 = (-pi/2) + 2pi*k

x = pi + 4pi*k   or    x = -pi + 4pi*k

Where k is any integer.

If we make a table of some example k values, then we'll find that we could get the following outputs:

and so on. These are the odd multiples of pi.

So we can effectively condense those x equations into the single equation x = pi+k*pi

That equation is the same as x = (k+1)pi

The graph is below. It shows we have jump discontinuities. These are not removable discontinuities (since we're not removing a single point).

Step-by-step explanation:

12 / 42 x 2 / 2 = 24 / 84

Step-by-step explanation:

3(5x+2)+4x=44

1st: You would do Distributive Property

        15x+6x+4x=44

Then: Combining Like Terms

           15x+6x =21x+4x=25

           25x=44

     Answer = 44/25 or 1.75

Answer:

d=14

Step-by-step explanation:

1d/6+2/3=1(d-2)/4

Find the L.C.M.

d+4/6=d-2/4

Cross multiply

4d+16=6d-12

Collect like terms

16+12=6d-4d

28=2d

Divide through by the coefficient of d

2d/2=28/2

d=14

Answer:

d = 20

Step-by-step explanation:

1/6*d + 2/3 = 1/4*(d - 2) do the multiplying

d/6 + 2/3 = (d-2)/4 now add fraction

d/6 + 2/3 to add these up we need to multiply 2/3 with 1/2 and it will be 4/6

d/6 + 4/6 = (d+4)/6

(d+4)/6 = (d-2)/4 cross multiply

4d + 16 = 6d - 24 add like terms

16 + 24 = 6d - 4d

40 = 2d divide both sides by 2

20 = d

Answer:

The student made an error during the distributive property in the second step where they multiplied 0.15 by -0.2 to equal -0.3 when it should have been -0.03.

Step-by-step explanation:
