Give the function y=-5x+12, what is the output (y) when the input, x=-2?

Answer:

$11.50

Step-by-step explanation:

I did give an explanation here but some one deleted it. :( I will attach the graph below though.

Answer:

$7.50

Step-by-step explanation:

Divide the 11.25 by 3 (since there are 3 bags) you should get 3.75 now multiply the 3.75 by 2 (since marco need 2) and you get 7.50

Answer = 1cm

27,35 hcf = 1 so 1cm is a large slice.

Answer:

x5

Step-by-step explanation:

Answer:

x = 2 or

x = 9

Step-by-step explanation:

x² - 11x + 18 = 0

x² - 9x - 2x + 18 = 0

x(x - 9) - 2(x - 9) = 0

(x - 2)(x - 9) = 0

x - 2 = 0 or x - 9 = 0

x = 2 or x = 9

Thus, x = 2 or 9

Answer:

x = 2, x = 9

Step-by-step explanation:

Given

x² - 11x + 18 = 0

Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)

The factors are - 2 and - 9 , since

- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus

(x - 2)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 9 = 0 ⇒ x = 9

85 square feet

Step-by-step explanation:

what we know: complete 6.8 square feet every hour

what we want to know: how much square feet will be compeletein 12 1/2 hours?

12 1/2 is 12.5

6.8 square feet time 12.5 hours gives you 85 square feet :)

Answer:

The slope is 0.9

Step-by-step explanation:

You'll want to start by labeling the points at (1,2.3) and at (6,6.8) which is the first pairs that you are given. You'll want to find use the formula to find the rise and the run which I'll give

(6.8-2.3)/(6-1) which is 4.5/5 which is 0.9

So for each week you'll make a total of 0.9 million dollars.

Answer:

[tex]P=\frac{C}{4} -5[/tex]

Step-by-step explanation:

Step one:

given

cost  per drive= $20

additional fee per person= $4

let the number of persons be p

and the total cost be C

The total cost function is expressed as

[tex]C=20+4p[/tex]

Step two:

Required:

We want to make P subject of the cost function

Take 20 to the other side we have

C-20=4p

divide through by 4

P=C-20/4

simplify

P=C/4-5

[tex]P=\frac{C}{4} -5[/tex]

Answer:

(a) 0.5184

(b) 0.0784

(c) 0.4816

Step-by-step explanation:

According to the given estimation over a 1-year period, 18​% of cars will need to be repaired​ once, ​7% will need repairs​ twice, and ​3% will require three or more repairs.

So, the probability that a car need repair once = 18/100=0.18 ...(i)

The probability that a car needs repair twice = 7/100=0.07 ...(ii)

The probability that a car needs repair thrice or more = 3/100=0.03 ...(iii)

From equations (i), (ii), and (iii), the probability that a car needs repair = (0.18+0.07+0.03) = 0.28 ...(iv)

The probability that a car doesn't needs repair = 1-(0.18+0.07+0.03)= 1-0.28=0.72 ....(v)

Given that I own two cars, denoting the cars by A and B.

(a) The probability that neither will need​ repair=(Probability that car A doesn't need repair) and (Probability that car B doesn't need repair)

=0.72 x 0.72 [ from equation (v)]

=0.5184

(b) The probability that both will need​ repair = (Probability that car A needs repair) and (Probability that car B needs repair)

=0.28 x 0.28 [ from equation (iv)]

=0.0784

(c) The probability that at least one car will need​ repair= 1 - (The probability that neither will need​ repair)

=1-0.5184 [ by using part (a)]

=0.4816

Answer:

The units of the displacement are (3, 5) → T (x + 3, y + 5)

Step-by-step explanation:

The rules of translation of a point

∵ Point (4, 2) is translated by (h, k)

∵ Its image is (7, 7)

∴ The x-coordinate of the point is increased from 4 to 7

∴ The point is translated to the right by h units

∵ 4 + h = 7

∴ h = 7 - 4 = 3

∴ The point is translated to the right 3 units

∵ The y-coordinate of the point is increased from 2 to 7

∴ The point is translated up by k units

∵ 2 + k = 7

∴ k = 7 - 2 = 5

∴ The point is translated up 5 units

∴ The point is translated 3 units right and 5 units up

∴ The units of the displacement are (3, 5) → T (x + 3, y + 5)

Answer:

x = 6

Step-by-step explanation:

3x + 5 = 23

you wanna subtract 5 from both sides

3x = 18

now you wanna divide 3 from both sides to get x by itself

x = 6

Answer:

6.9 x 103

Step-by-step explanation:

Answer:

CD = 18 units

Step-by-step explanation:

Given a rectangle with length x and width y, the perimeter is:

P = 2x + 2y

Here, we note that x = AB = CD, y = AD = BC, and P = 64 units. So:

2AB + 2BC = 64

We know that AB = 3z and BC = 2z + 2; plug these in:

2 * (3z) + 2 * (2z + 2) = 64

6z + 4z + 4 = 64

10z = 60

z = 6

Now that we've solved for z, we can find AB and, hence, CD because AB = CD.

AB = 3z = 3 * 6 = 18 units

Thus, CD = 18 units, as well.

Answer:

no this is not fair

Step-by-step explanation:

Answer:

b. is not fair

c. not fair

4. Just search on google for a recipe or say PB&J

5. Proprtains can tell you if something is unfair by something being higher than normal.

Step-by-step explanation:

b. if the second option got 75  points then that'll be higher than 15 questions answered correctly.

c. if option 2 traded 24 football cards then that'll be way over 15.

4. More jelly than peanut butter would mean I would have to add more peanut butter.

5. I traded 15 socks and got 10 apples, however, my friend traded 10 socks and got 9 apples. This means if he traded 15 socks then it would've been over 10 apples.

Hope this helped!

10 should be your answer

The solution is : the value of x that makes f(x) = 15, is x = 10.

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

we have,

Step 1: Define

f(x) = 2x - 5

f(x) = 15

Step 2: Solve for x

Substitute in f(x) [Function]:                                                                             15 = 2x - 5

[Addition Property of Equality] Add 5 on both sides:                                    20 = 2x

[Division Property of Equality] Divide 2 on both sides:                                  10 = x

Rewrite:                                                                                                             x = 10

hence, The solution is : the value of x that makes f(x) = 15, is x = 10.
