- 1/9x+2.4=6 what is x

Answers

First we’re going to subtract 2.4 from both sides
-1/9x+2.4-2.4=6-2.4
Then we’re going to simplify
-1/9x=3.6
Then multiply both sides by -9
(-1/9x) (-9) =3.6 (-9)
Then you just Gotta simplify

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.

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50

➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.

Answers

Answer: the answer is x= 1

Step-by-step explanation:

So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50

our first step is Simplify both sides of the equation so:

11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:

(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)

**we know 11.5 + -11.5 will cancel each other since they are opposite**

so it will be 1.15x= 1.15

now the very last step is to divide 1.15x on both sides which gives us 1

Explain, in detail, how you know if these are equivalent.

Answers

Answer:

they are equivalent.

Step-by-step explanation:

to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!

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".

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

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.
