Does the equation have one solution, no solutions, or all solutions? 7x + 4 = 9(x-1)
Describe how to determine if a number is a solution to an equation.
Step-by-step explanation:
Determine whether a number is a solution to an equation.
Substitute the number for the variable in the equation.
Simplify the expressions on both sides of the equation.
Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

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?
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
What is the y-intercept of the line shown? (4 points)
A. 0
B. 1

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.
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

A scuba diver descends in the water at a rate of 2312 feet per minute for 2.6 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 28 feet per minute for 2 minutes.
What is the scuba diver's position relative to sea level after the 4.6 minutes?
Enter your answer as a decimal in the box.
ft
2312 FPM for 2.6 minutes
2312 x 2.6 = 6011.2
28 FPM for 2 minutes
28 x 2 = 56
6011.2 descend
55 ascend
0-6011.2 = -6011.2
ans + 56 = -5955.2

help me plz :)
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

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 )
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

Answer:
a. False
b. True
c. True
d. I think it's true
e. False
Step-by-step explanation:
a. The unit rate is 19.75 gallons per minute
b. It is true because when x=0 y is also equal to 0, therefore it passes through the origin
c. 19.75 is about 20, and 20 multiplied by 5 is 100
d. Like I said before I don't know but I hope you get it correct ._.
e. When x=8 the equation would be 19.75*8 which is equal to 158 not 150

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

Two linear functions are represented in different formats.
Function 1:
x y
0 5
2 11
5 20
8 29
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.
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.

Mr. Aba builds a circular patio with a diameter of 12 feet. He covers the patio with paving stones. The cost of the paving stones is $10.50 per square foot. To the nearest dollar, how much do the paving stones cost.
Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
