Eight times the difference of y and nine

Answers

Answer 1
Answer:

Eight times the difference of y and nine will be 8(y - 9).

It should be noted that eight times the difference of y and nine simply means that one has to subtract 9 from y and then multiply the difference by 8.

Therefore, eight times the difference of y and nine will be 8(y - 9).

In conclusion, the correct option is 8(y - 9).

Using ordered pairs (0,4) and (-4,-3) what is the slope

Answers

soo your supposed to use delta y over delta x and then you get the slope but it is 7/4

Answer:

1.75, or -7/-4

Step-by-step explanation:

The equation to find slope is y value 2 - y value 1 (this is the numerator). The denominator would be the same but instead of y values they would be x values. Input your coordinates into the equation (-3 - 4/-4 - 0) and subtract to get -7/-4. Then, divide/simplify to get 1.75.

(1 point) The number of households with cable TV service in a certain community, N, begins at only 55 households and has seen a fivefold increase every 17 years. Give the constants a, b, and T so that N is represented by a function of the form N=abt/T, where t is the time in years since N was first measured.

Answers

Answer:

a=55

b=5

T=17

Step-by-step explanation:

The general form of the equation is:

N(t)=ab^{(t)/(T)}

For t = 0:

N(0)=ab^{(0)/(T)}\nN(0) = a = 55\na=55

Since there has been a fivefold increase after 17 years, at t = 17, N(17) = 55*5

N(17)=55b^{(17)/(T)}\n55*5 = 55b^{(17)/(T)}\nb^{(17)/(T)} = 5

If at every 17*n years there in an increase of 5^n, one can deduct that the values for T and b are respectively 17 and 5:

b^{(t)/(T)}= 5^{(17n)/(17)}

Therefore, the function that represents N(t) is:

N(t)=55*5^{(t)/(17)}

If w = 7a + 4b, which of the following equations is solved for a?

Answers

Answer: a= w - 4b/ 7

Step-by-step explanation:

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 70% salt and Solution B is 95% salt. She wants to obtain 150 ounces of a mixture that is 75% salt. How many ounces of each solution should she use?

Answers

Answer:

Solution A: 120 ounces

Solution B: 30 ounces

Step-by-step explanation:

Let's call A the amount of Solution A. Solution A is 70% salt

Let's call B the amount of Solution B. Solution A is 95% salt

The resulting mixture should have 75% salt and 150 ounces .

Then we know that the total amount of mixture will be:

A + B = 150

Then the total amount of salt in the mixture will be:

0.7A + 0.95B = 0.75 * 150

0.7A + 0.95B = 112.5

Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -0.95 and add it to the second equation:

-0.95A -0.95B = 150 * (-0.95)

-0.95A -0.95B =-142.5

-0.95A -0.95B =-142.5

                      +

0.7A + 0.95B = 112.5

--------------------------------------

-0.25A = -30

A = (-30)/(-0.25)

A = 120\ ounces

We substitute the value of A into one of the two equations and solve for B.

120 + B = 150

B = 30\ ounces
