Answer:

3  3/11

Step-by-step explanation:

The best way to divide fractions is to not divide them at all.

Convert both mixed numbers into improper fractions.

4 times 2 is 8

8 + 1 is 9

I have 9/2 halves. Don't forget to put the negative back in.

1 times 8 is 8

8 + 3 is 11

I have 11/8 eighths. Dont forget to put the negative back in.

You will end up with

-9/2 ÷ -11/8

Flip the second fraction and change the division sign to a multiply sign

-9/2 × 8/-11

Multiply the numerators together and the denominators together

-9 x 8 and 2 x -11

-72 / -22

Dividing a negative by a negative will give us a positive

72 / 22

Simplify by dividing the top and bottom by 2

36/11

We cannot simplify further. You can answer like this or convert back into a mixed number.

There are 3 sets of 11 in 36, with 3 left over

Answer:

[tex] = - (5 \frac{3}{5} )[/tex]

Step-by-step explanation:

[tex] - 4 \frac{1}{2} \div ( -1 \frac{3}{8} )[/tex]

[tex] = - 4 \frac{1}{2} \div -1 \frac{3}{8} [/tex]

[tex] = \frac{(2 \times ( - 4) + 1)}{2} \div \frac{(8 \times ( - 1) + 3}{8} [/tex]

[tex] = \frac{ - 7}{2} \div \frac{ - 5}{8} [/tex]

[tex]= \frac{ - 7}{2} \times \frac{8}{ - 5} [/tex]

[tex] = \frac{ (- 7 )\times 8}{2 \times ( - 5)} [/tex]

[tex] = \frac{ - 56}{( - 10)} [/tex]

[tex] = - (5 \frac{6}{10} )[/tex]

[tex] = - (5 \frac{3}{5} )[/tex]

Step-by-step explanation:

Answer:

[tex]x2=\frac{y2-y1}{m} +x1[/tex]

Step-by-step explanation:

Step 1: Multiply both sides by (x2-x1)

m(x2-x1)=y2-y1

Step 2: Divide both sides by m

x2-x1=(y2-y1)/m

Step 3: Add x1 to both sides

[tex]x2=\frac{y2-y1}{m} +x1[/tex]

Answer:

z

Step-by-step explanation:

The Z score is the number of standard deviations a randomly selected value is from the population mean. Using a Z look-up table, the Z score can be converted into the probability of drawing the value from the population.

Answer: f(x)=x-1

Step-by-step explanation: If you observe the points you will notice that each output is exactly one less than the input, x, so the function is f(x)=x-1.

Answer: 300.3858/ maybe 300.385

Step-by-step explanation: 4 2/7 as decimal= 4.29 x (-18) = -77.22 x -3.89=  300.3858 (3.89 = decimal form of -3 8/9)  300.3858 x 1 = 300.3858

Answer:

No, it is not a solution

Step-by-step explanation:

First let's simplify 2x - 5 = 3

2x - 5 = 3                            (add 5 to both sides)

2x - 5 + 5 = 3 + 5

2x = 8                                 (divide both sides by 8)

2x ÷ 2 = 8 ÷ 2

x = 4

As you can see, 7 is not a solution for 2x - 5 = 3

We can double check by substituting 7 for x:

2(7) - 5 = 3

14 - 5 = 3

9 ≠ 3

Answer:

the answer is second choice.

Answer:

where is the expression

The ODE

y''' - 7y'' + 8y' + 16y = 0

has characteristic equation

r ³ - 7r ² + 8r + 16 = 0

which can be factorized as

(r - 4)² (r + 1) = 0

Then the characteristic solution to the ODE is

y(x) = C₁ e ⁴ˣ + C₂ x e ⁴ˣ + C₃ e ⁻ˣ

This represents an absolute value graph, therefore the distance between them is  8.944272

Step-by-step explanation:

d = 8.944272

For:

(X1, Y1) = (6, 2)

(X2, Y2) = (-2, 6)

Distance Equation Solution:

d=(−2−6)2+(6−2)2−−−−−−−−−−−−−−−−√

d=(−8)2+(4)2−−−−−−−−−−√

d=64+16−−−−−−√

d=80−−√

Answer:

2^4*5*7

Step-by-step explanation:

2^4*5*7

Answer:

1.40

Step-by-step explanation:

When we look at the diagram, we want to find what is opposite and adjacent as well as the hypotenuse to the given degree.

AB = hypotenuse

BC = opposite

AC = adjacent

Since we are looking to find BC and we are given 2 on AC. We have opposite and adjacent which means we are using TOA in SOH-CAH-TOA. So aftrr identifying these, we can set up our equation:

tan (35) = x / 2

Tan(35) is .7002 so we can replace that part of our equation.

.7002 / 1 = x / 2

The 1 is there as a place holder. We can then cross multiply.

1 × x = 1

.7002 × 2 = 1.4004

The answer we have now is 1.4004, but we have to round to the nearest hundredth. So then, our final answer is 1.40.

BC = 1.40

Answer:

$650.  This was the original price.

Step-by-step explanation:

Let p represent the original price.

The following expression calculates the value of p:  (1 - 0.38)p = $403.  Note that '1' indicates full price and that '0.38' indicates a 38% discount.

(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.

Dividing both sides by 0.62 yields $650.  This was the original price.

Answer:

$650

Step-by-step explanation:

Line up $ with $ and % with % then cross multiply

$403 represents ........100% full price -38% discounted  = 62%

$ x amount of the original price represents .........................100%

x*62 = 403*100, cross multiply

x = (403*100)/62, divide both sides by 62

x = $650

Answer:

a) 73, 82, 91

b) arithmetic

Step-by-step explanation:

a) We add 9 after each term, making the common difference 9.

As such, 64 + 9 = 73

73 + 9 = 82

82 + 9 = 91

b) This sequence is arithmetic because it has a common difference, if it had a common ratio, it would be geometric.
