Find the increasing functions. Then arrange the increasing functions in order from least to greatest rate of change. (not all of the functions will be used)
y= 5/2x + 10
y= -1/2x + 1/2
y= 3/2x - 11/2
y= 1/2x - 2
y= 4/3x - 7/3
y=3/4x - 10

Answers

Answer:

to a function is increasing we have to find the slope of the function

the higher the slope the faster the growth

Step-by-step explanation:

slope = 5/2. which is 2.5slope 2 = -1/2 which is -0.5slope 3 = 3/2 which is 1.5slope 4 = 1/2 which is 0.5slope 5= 4/3 which is 1.33slope 6 = 3/4 which is 0.75

so the function in increasing order

y= -1/2x + 1/2

y= 1/2x - 2

y=3/4x - 10

y=4/3x -7/3

y=3/2x-11/2

y=5/2x +10

We move all terms to the left:

16+x-(-34)=0

We add all the numbers together, and all the variables

x+50=0

We move all terms containing x to the left, all other terms to the right

x=-50

(Hope that help you out) God bless!

Answer:

An airplane flies at an altitude of 14,690 feet while a submarine is submerged at a depth of 521 feet below the surface of the ocean. What is the difference between these two elevations?

Answers

Answer:

15,211 feet

Step-by-step explanation:

According to the question,  given data are as follows:

Airplane altitude = 14,690 feet above

Submarine depth = 521 feet below

So, let the difference between these two elevation be d,

So, we can calculate difference by using following formula:

Difference = Airplane altitude + Submarine depth

By putting the value, we get

Difference = 14,690 + 521

= 15,211 feet

Answers

a = 49

You find this by adding 109 and 30, then subtracting from 180.

b = 55
c = 55

we know that the place where the two lines meet has to be 360, so we subtract the two 109s from it. Divide the answer by 2. This number is added to 54 and subtracted from 180. This gives us 55. c is in a position that equals 55.

Saffron is very expensive spice. A shop selling saffron for $ 7.35 per gram.
Write the formula for the cost (y), in dollars, of g grams of saffron.*
a) y = 7.35g
b)g=7.35 y
c) y = 7.35+g​

Answers

Answer:

A

Step-by-step explanation:

B is wrong because it's saying to multiply the cost by $7.35.

C is wrong because it's telling you to add the amount of grams to $7.35.

A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.

Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .

Answers

Answer:

5.27 lb

Step-by-step explanation:

Given that,

Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :

Let Eric has F floor.

3F = 15.81 ...(1)

We need to find how much flour Eric has.

Dividing both sides by 15.81.

F = 15.81/3

F = 5.27 lb

Hence, Eric has 5.27 lb of flour.
