Write a rule for the linear function in the table (1)(3),(2)(2),(3)(1),(4)(0)

Answers

Answer 1

Answer: y= -x + 4
I just did this one. Look at the steps I. The other one.

Answer 2

Answer: Here, f(x) = {(1,3), (2,2), (3,1), (4,0)}
So, rule for this function is {x+n, y-n}

Where, n = number of steps, & x, y are the initial values of the function which is 1 & 3 respectively

Plan a recipe for 38 minutes of long distance calling using plan b she paid $4.13 for 59 minutes find the unit rate for each which plan cost more per minute

Answers

Answer:

Plan A has a unit rate of approximately $0.1087 per minute.

Plan B has a unit rate of approximately $0.0700 per minute.

Step-by-step explanation:

Plan A:

38 minutes of long-distance calling

Total cost: $4.13

To find the unit rate for Plan A, divide the total cost by the number of minutes:

Unit Rate for Plan A = Total Cost / Number of Minutes

Unit Rate for Plan A = $4.13 / 38 minutes ≈ $0.1087 per minute

Plan B:

59 minutes of long-distance calling

Total cost: $4.13

To find the unit rate for Plan B, divide the total cost by the number of minutes:

Unit Rate for Plan B = Total Cost / Number of Minutes

Unit Rate for Plan B = $4.13 / 59 minutes ≈ $0.0700 per minute

The sales tax on a new camera is $5.60, which is 8% of the total price.What is the price of the camera?

Answers

$5.60 = 0.08x
Solve by dividing both sides by 0.08
$5.60 ÷ 0.08 = $70
Price: $70

the total price is 6.05 because 8 percent of 5.60 is .45 so 5.60+.45 is 6.05

Mr. Ferrier invested $26,000. Some was invested in bonds that made a 5% profit, and the rest was put in stocks that made an 8% profit. How much did mr. Ferrier invest in bonds if his total profit on both types of investments was $1,420

Answers

Answer:

$22000

Step-by-step explanation:

x*0.05+(26000-x)*0.08= 1420

0.05x - 0.08x + 2080= 1420

0.03x=2080 -1420

0.03x= 660

x= 660/0.03

x= 22000

$22000 = 5% bonds

$4000 = 8% stocks

Answer:

bonds=22000

stock=4000

Step-by-step explanation:

let b for bonds , and s for stock

b+s=26000

0.05 b +0.08 s=1420

to solve (by elimination)

1- multiply first equation with 0.05 to eliminate b

0.05 b+0.05 s=1300

0.05b+0.08s=1420

subtract two equations:

0.05b+0.05s-0.05b-0.08s=1300-1420

-0.03s=-120

s=120/0.03=4000

b+s=26000

b=26000-4000=22000

check:0.05(22000)+0.08(4000)=1420

Find the product.(-d + 4)(-d - 4)
-d2 - 16
d2 - 16
d2 + 16
d2 - 8d - 16

Answers

(-d + 4) (-d - 4) = 0
-d(-d - 4) + 4(-d - 4) = 0
d² + 4d - 4d - 16 = 0
d² - 16 = 0 2nd choice.

We can find the value of d.
d² - 16 = 0
d² = 16
√d² = √16
d = 4

to check:
(-4+4) (-4 - 4) = 0
0 (-16) = 0
0 = 0

Multiplication property of 0. Any number multiplied by 0 is equal to 0.
