Two linear functions are represented in different formats.

Function 2: (image below)


Which statements are true?

Select each correct answer.


Function 1 has a greater rate of change than function 2.


Function 2 has a greater rate of change than function 1.


Function 1 has a greater y-intercept than function 2.


Function 2 has a greater y-intercept than function 1.

Answers

Answer:

Function 1 has a greater Y intercept than that of function 2

Step-by-step explanation:

Y intercept can be found by replacing x by 0 or

x = 0 0f the given function.

in this case Function 1 has a Y intercept of 5 when x =0

on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.

you can now clearly see that

y = 5 > y = -1

---> 5>-1

so that's why we conclude that 1 has a greater Y intercept.

13,860.42

Which best represents the greatest amount of change that took place from one day to the next day over the four-day period?
a loss of 93.98 points
a loss of 72.47 points
a gain of 72.47 points
a gain of 93.98 points

Answers

Answer:

C) a gain of 72.47 points

Step-by-step explanation:

because on 1/28 it has 13,881.93 and the next day 1/29 it has 13,954.4

subtract 13,954.4 - 13,881.93= 72.47

72.47 is the greatest amount change

And it can’t be 93.98 because in the instructions it said one day to the next not 2 day’s in advance

Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).
Which point lies on Line UV?

A. ( 7 , 12 )
B. ( 10 , 14 )
C. ( 16 , 22 )
D. ( 20 , 20 )

Answers

Answer:

D

Step-by-step explanation:

gradient is change in y/change in x

gradient of UV = 14-8/12+4=3/4

use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept

use one of the coordinates of U or V, I'll use (4,8)

[tex]y = mx + c[/tex]

[tex]8 = \frac{3}{4} (4) + c[/tex]

[tex] 8 = 3 + c[/tex]

c is 5

the equation for UV is

[tex]y = \frac{3}{4} x + 5[/tex]

insert each X coordinate given in the question to see if it gives the same y coordinate

when x is 20, y is also 20 so the answer is D

the answer is D hope this helps

Question about finding intercepts from a table. Hope someone can answer!

Answers

Basically you have to use the table to find the equation of the line, then plug in a point into x and y and the b you will get is your y-intercept.

Now if you are familiar with the equation of a line in slope intercept form, it will look like this: y=mx+b. Here the ‘m’ is the slope and the ‘b’ is your y-intercept. What you need to do is use any two points given from the table and find the slope. To do that follow the steps below:

1. Pick two points. Let’s take the first two.
(-28, -54) And (-21, -40)

2. Subtract the two y values, -40 - (-54) = 14
3. Subtract the two x values, -21 - (-28) = 7
4. Now take your answer from step 2 and divide it by your answer in step 3. This will be 14/7, which will be 2.

Your answer from step 4 is your slope, or ‘m’.
(That series of steps was basically change in y over change in x, you can look that up if you are still confused)

Now that you know m, your incomplete equation will be this:
y=2x+b.

Next you will pick any point from the table again, and replace it with x and y in the equation. Let’s pick the second point, (-21,-40)

Plug this in: -40 = 2(-21) + b
Solve for b and you will get your answer.
-40 = -42 + b
b=2
Your answer is 2, that is the y intercept.
(The full equation of the line from that table would be y=2x+2)

Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?

Answers

Answer:

$1343

Step-by-step explanation:

Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?

You need to turn 15% into a decimal.

Move the decimal point to the left 2 spaces.

15 ---> 1.5 ---> 0.15

Now multiply 0.15 by $1,580.

0.15 × $1,580

Which is $237.

Now subtract $1580 - $237.

Which is $1343.

Answer:

$1580*15/100=$237that is discount rate.

$1580-237=$1343 actually pay

3/4c-7/12+7/24c+2/3-1/6c
simplify the expression

Answers

Answer: 7/8c + 1/12

Explanation: separate the c terms and the non-c terms. 3/4c + 7/24c - 1/6c = 7/8c

-7/12 + 2/3= 1/12

therefore, it’s 7/8c + 1/12

The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c

Combined likely terms,

⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3

⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12

⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12

⇒ (42/24)c + 1/12

⇒ (21/12)c + 1/12

Hence "The simplification of the given is (21/12)c + 1/12".

Answers

Answer:1/5

Explanation: 1/35 divided by 1/7= 1/5. 1/7 of/x 1/5= 1/35.

The value of unknown number would be equal to  1/5

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the unknown number.

A negative divided by a negative is positive, then;

1/7 of x  is 1/35

1/35 divided by 1/7

1/7 of x 1/5 = 1/35.

x = 1/5

Therefore, The value is x = 1/5
