Answer:

B. 8

Step-by-step explanation:

By evaluate, they mean substitute in the values and solve.

x + 3y - n

= 10 + 3(2) - n

= 10 + 6 - 8

= 8

Twice last​ month, Judy Carter rented a car from a car rental company and traveled around the Southwest on business. The company
tatiyna

Answer:

$31 and $0.16

Step-by-step explanation:

Let the rental company rents its car for a $x daily fee and a $y as the mileage charge.

So, on his first trip Judy drove 450 miles for 4 days and the rental cost was $196.

So, 4x + 450y = 196 ......... (1)

⇒ 12x + 1350y = 588 ......... (a)

On his second trip Judy drove 200 miles for 3 days and the rental cost was $125.

Hence, 3x + 200y = 125 ......... (2)

⇒ 12x + 800y = 500 .......... (b)

Now, solving equations (a) and (b) we get,  

550y = 88

⇒ y = $0.16

Now, from equation (2) we get 3x = 125 - 200y = 93

⇒ x = $31

So, the daily fee is $31 and the mileage charge is $0.16. (Answer)

One function has an equation in slope-intercept form: y = x + 5. Another function has an equation in standard form: y + x = 5. E
vlada-n [284]

Without converting the equations to the same form, the property that must be different in the functions is the slope

<h3>How to determine the difference in the properties of the functions?</h3>

From the question, the equations are given as

y = x + 5

y + x = 5


From the question, we understand that:

The equations must not be converted to the same form before the question is solved

The equation of a linear function is represented as

y = mx + c

Where m represents the slope and c represents the y-intercept

When the equation y = mx + c is compared to y = x + 5, we have

Slope, m = 1

y-intercept, c = 5

The equation y = mx + c can be rewritten as

y - mx = c

When the equation y - mx = c is compared to y + x = 5, we have

Slope, m = -1

y-intercept, c = 5

By comparing the properties of the functions, we have

  • The functions have the same y-intercept of 5
  • The functions have the different slopes of 1 and -1

Hence, the different properties of the functions are their slopes

Write an equation for the nth term of the arithmetic sequence 56, 48, 40, 32, ....
Wittaler [7]

Answer:

an = 56-8(n-1)

Step-by-step explanation:

This is an arithmetic sequence

The common difference is 48 - 56 =-8

a1 = 56

an = a1+d(n-1)

an = 56-8(n-1)
