Is the following a Function?

Answer:

Richard's gross pay for the month was $ 4,512.5.

Step-by-step explanation:

Given that Richard Klein works as auto mechanic and earns the following commission rates: 3.00 percent for oil changes, 5.00 percent for tune ups and 6.25 percent on auto parts sales; and he is guaranteed a minimum salary of $ 2,450.00 per month, if last month he brought in $ 2,500.00 in oil changes, $ 4,500.00 in tune ups and sold $ 28,200.00 in parts, to determine what is his gross pay for the month the following calculation must be performed:

2,450 + (2,500 x 0.03) + (4,500 x 0.05) + (28,200 x 0.0625) = X

2,450 + 75 + 225 + 1,762.5 = X

2,450 + 2,062.5 = X

4,512.5 = X

Thus, Richard's gross pay for the month was $ 4,512.5.

Answer:

B: Using x and y factor results in an expression of greater value than using x and y as terms.

Step-by-step explanation:

For her first expression, x and y are factors;

xy

For her second expression, x and y are written as terms;

x + y

For x and y are both negative integers, then;

-x * -y = xy  ............... 1

-x + (-y) = - x - y

            = - (x + y)  .............. 2

Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.

Answer:

y = x+1

Step-by-step explanation:

Slope-intercept form

(y = mx+b)

m = slope and b = y-intercept

The line crosses the y-axis at (0, 1), therefore the y-intercept (b) = 1

The slope (m) = 1

Because the slope is 1, it does not need to be written in the equation, as any number multiplied by 1 is that number.

Answer:

1 is inequality

replace the value were _2.

Answer:

a35

Step-by-step explanation:

the sine is greater than the cosn

Answer:

B

Step-by-step explanation:

The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.

Answer:

x = - 3.75

y = 28.75

Step-by-step explanation:

[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]

Since, x + y = 25

Therefore, y = 25 - x..... (1)

5x + y = 10......(2)

Plug y = 25 - x in equation (2), we find:

5x + 25 - x = 10

5x - x = 10 - 25

4x = - 15

x = - 15/4

x = - 3.75

Plug x = - 3.75 in equation (1), we find:

y = 25 - (- 3.75)

y = 25 + 3.75

y = 28.75

(x, y) = (-3.75, 28.75)

Answer:

It is the first answer choice

Answer:

a) 40 inches

b) No it will not fit inside

Step-by-step explanation:

Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )

a) If it is 30 inches tall, how wide is the screen ?

Diagonal ² = Width² + Height²

Diagonal = 50 inches

Height = 30 inches

50² = Width² + 30²

Width² = 50² - 30²

Width = √50² - 30²

Width = √(1600)

Width = 40 inches

b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?

No it will not fit inside

This is because, the width of the TV is the above calculation is 40 inches. This is wider than the width of the TV cabinet, hence, it won't fit inside

Answer:

1352 miles

Step-by-step explanation:

since city t, s, and P make a right angle we can use the Pythagorean theorem to find the hypotenuse (distance from t to p) 1180 squared=1,392,400 and 660 squared =435,600 so now we add them together and take its square root which is 1352.0

Answer: k = 27

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27

Answer:

$30.4

Step-by-step explanation:

fist we figure out what 5% of 32 is which is 1.6 then we subtract it from the total cost 32 - 1.6 = 30.4

Answer:

$35

Step-by-step explanation:

Find the cost of 1 apple

$25/50 = 0.5

1 apple costs 50 cents/ 0.5 dollar

Multiply by 70 to find the cost of 70 apples

$0.5 x 70 apples = 35

Given:

The equations of a system of equations are

[tex]y=-2x^2+3x-1[/tex]

[tex]x+y=-1[/tex]

To find:

The solution of the given system of equations.

Solution:

We have,

[tex]y=-2x^2+3x-1[/tex]           ...(i)

[tex]x+y=-1[/tex]                      ...(ii)

Using (i) and (ii), we get

[tex]x+(-2x^2+3x-1)=-1[/tex]

[tex]x-2x^2+3x-1+1=0[/tex]

[tex]-2x^2+4x=0[/tex]

Taking out the common factors.

[tex]2x(-x+2)=0[/tex]

Using zero product property,we get

[tex]2x=0[/tex] and [tex]-x+2=0[/tex]

[tex]x=0[/tex] and [tex]2=x[/tex]

For x=0, we have

[tex]0+y=-1[/tex]

[tex]y=-1[/tex]

For x=2, we have

[tex]2+y=-1[/tex]

[tex]y=-1-2[/tex]

[tex]y=-3[/tex]

Therefore, the two solutions of the given system of equations are (0,-1) and (2,-3).
