Pedro works as a newspaper deliverer. He receives a base pay plus an additional amount per newspaper delivered. Last week, Pedro

Gemiola [76]

Y = base pay + (variable pay * x)

37.50 = base pay + (variable pay * 5)
75 = base pay + (variable pay * 20)

let v be the variable pay:
base pay = y - variable pay * x
37.50 - 5v = 75 - 20v
-5v + 20v = 75 - 37.50
15v = 37.50
v = 37.50/15
v = 2.5

37.50 - 5(2.5) = 75 - 20(2.5)
37.50 - 12.50 = 75 - 50
25 = 25

base pay is 25 ; variable pay is 2.50 per newspaper delivered.

y = 25 + 2.50x

6 students want lemonade and 12 students

Ksenya-84 [330]

Answer:

2:1

Step-by-step explanation:

well we show ratio by the sign ' : '

ratio of iced tea to lemonade= 12:6

now we reduce it to minimum by dividing it with same number.

12 is divisible by 6

so,

the reduced form is = 2:1

therefore,

ratio of the number of students who want iced tea to the number of students who want lemonade = 2:1.

The difference between twice a number, x, and a smaller number, y, is 3. The sum of twice the number and the smaller

azamat

Answer:

y=2x+3 and y=-2x-3

Step-by-step explanation:

First situation:

2x-y=3

making y subject

y=2x+3

Second situation:

2x+y=-3

making y subject

write a equation 2 solve for x you are only writing the equation they said it was wrong 8x+10 12x -18 or did i do it backwards d

andrezito [222]

Answer:

x=1.25

Step-by-step explanation:

8x+10=12x-18-10=7

8x+12x=10-18+10+7

20x=25

d.b.s by 20

20x/20=25/20

1=1.25 

I thinks I am right if not pls reply me with the correct answer pls

x=1.25

A particle moves along the x-axis with position function s(t) = ecos(x). How many times in the interval [0, 2π] is the velocity

Ede4ka [16]

Answer:

It goes to zero three times

Step-by-step explanation:

s(t) = e^ cos(x)

To find the velocity, we have to take the derivative of the position

ds/dt = -sin x e^ cos x dx/dt

Now we need to find when this is equal to 0

0 = -sin x e^ cos x

Using the zero product property

-sin x=0 e^cos x= 0

sin x = 0

Taking the arcsin of each side

arcsin sinx= arcsin 0

x = 0 ,pi, 2 pi

e^cos x= 0

Never goes to zero
