Answer:

4

x value increases  by 2 in the time it takes y value to increase by 8

8/2 = 4

Answer:

y=6x+20

Step-by-step explanation:

m= y2-y1/x2-x1

m= -4-8/-4-(-2)= 12/-2= 6/1

y= mx+b

y= 6x+b

8= 6(-2)+b

8=-12+b

+12  +12

b= 20

Answer:

2 zeros

Step-by-step explanation:

Here, we want to identify the number of zeros for the function

The number of zeros a particular function has is dependent on the degree of the function

This particular function is quadratic and has a degree of two

So what this means is that it is expected that the function has two zeros

Answer:

Please check the explanation below.

Step-by-step explanation:

Some of the properties are defined as:

[tex]a(b+c) = ab+ac[/tex]

For example,

suppose a=3, b=4, c=5

3(4+5) = 3(4) + 3(5)

3(9) = 12+15

27 = 27

if (a=b), then a-c = b-c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a-c = b-c ⇒ 2-5 = 2- 5 ⇒ -3 = -3

if (a=b), then a+c = b+c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a+c = b+c ⇒ 2+3 = 2+3  ⇒ 5 = 5

if (a=b), then a×c = b×c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a×c = b×c ⇒ 2×5 = 2 × 5  ⇒ 10 = 10

if (a=b), then a÷c = b÷c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a÷c = b÷c ⇒ 2÷5 = 2 ÷ 3  ⇒ 2/5 = 2/5

Let us solve the given equation using the above properties.

7n-16=47                     Given

7n-16+16=47+16   1) Addtion property of Equality ∵ if (a=b), then a+c = b+c

7n=63                  2) simplify

n = 9                    3) Division property of Equality ∵ if (a=b), then a÷c = b÷c

Answer:

the answer for this is (2,2)

Answer:

Rs. 40

Step-by-step explanation:

Ravi paid the amount of Rs. 40 for the candies for her daughter's birthday.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

If the candies weighed 50 grams each, the total weight of the candies is 80 x 50 = 4000 grams.

To convert the weight from grams to kilograms, we divide by 1000. So, the total weight in kilograms is 4000 / 1000 = 4 kilograms.

If the price of candies was Rs. 10 per kilogram, the total cost for 4 kilograms is 4 x 10 = Rs. 40.

Therefore, he paid Rs. 40 for the candies.

Answer:

i dont know what you are asking, make your question more readable and clear

Step-by-step explanation:

This is a binomial probability experiment. Each trial is independent of one another, ie each roll is independent. The probability of getting an even number is 3/6 = 1/2 = 0.5 and that probability does not change from roll to roll. Furthermore, the value of n is fixed and not infinitely large. Lastly, each trial outcome comes down to two choices: either you get an even number, or you don't. So we've met the requirements of a binomial probability distribution.

The values of n, p and q are:

Answer:

A 6.24 I did this just yesterday and I'm sure I got it right

Answer:

D) 13.9 inches

Step-by-step explanation:

use the pythagorean theorem to solve this - a^2 + b^2 = c^2

8.5^2 + 11^2 = c^2

solving gets us a value of 193.25, so next, get the square root of that to the the diagonal length (13.90143...)

Step-by-step explanation:

w(2w - 30) = 5400

2w²- 30w = 5400

2w² - 30w - 5400 = 0

(w - 60 ) ( w + 45 ) = 0

w= 60 w= - 45

only take the positive value

therefore w = 60

Answer:

9:1, 18:2, 27:3, 36:4, 45:5 or 1,2,3,4,5

Step-by-step explanation:

This is the answer because:

1) We can see that eah ratio is being multiplied with the next number. We can say this because 9 x 2 = 18 and 1 x 2 = 2 which is 18:2 just like that 9 x 3 = 27 and 1 x 3 = 3 which makes the ratio 27:3.

2) If we keep on doing this, 9 x 4 = 36 and 1 x 4 = 4 which makes the ratio 36:4.

Therefore, the answer is 4.

Hope this helps! :D

Answer:

The original price of the item is $28.

Step-by-step explanation:

So to find the original price, we have to divide the sale price by the result of one minus the discount in percentage form.

So:

First convert 25% to a decimal, 0.25.

OP(original price) = 21 ÷ 1 - 0.25 =

1 - 0.25 = 0.75

21 ÷ 0.75 = 28.

Answer:

they tipped = 15% of 24.68 = 15/100*24.68 = 3.702

Step-by-step explanation:

Answer:

  Tip: $3.70  

  Total: $28.38

Step-by-step explanation:

  bill:    $24.68

  tip:     0.15 * 24.68 = $3.70

  Total:   24.68 + 3.70 = $28.38

Answer:

2 2/19

Step-by-step explanation:

5 cases in 2 3/8 hours

The unit rate of cases per hour is calculated by dividing the number of cases by the number of hours.

5/(2 3/8) = 5/(19/8) = 5 * 8/19 = 40/19 = 2 2/19

Answer:

2 2/19 cases per hour

Step-by-step explanation:

5 ÷ 2 3/8

~Turn the fraction on the left into an improper one

5 ÷ 19/8

~Copy Dot Flip

5/1 * 8/19

~Multiply

40/19 or 2 2/19

Answer:

4) (-3 , 2)

Step-by-step explanation:

Answer:

(-3, 2) because if you extend the line to the right more, it'll go directly through that point, but none of the others. also, if you plot the points, you can look at the line to see which point the line would go through
