Answer:
-1
Step-by-step explanation:
Plug 7 in for wherever there's an "x."
f(x) = 2(7) - 6
f(x) = 14 - 6
f(x) = 8
Now subtract 9 from 8.
8 - 9 = -1

let f(x)=5x-2 and g (x)=6x+3 find g(f(3))
Answer:
81
Step-by-step explanation:
f(x)=5x-2
g (x)=6x+3
g(f(3))
First find f(3)
f(3) = 5*3 -2
= 15-2
= 13
Then find g(13)
g(13) = 6*13 +3
=78 +3
= 81
Answer:
81
Step-by-step explanation:
Solve 3 as x
5(3)-2
15-2

Now use 13 as x
6(13)+3

If 3 is added to three quarters of a certain number ,the result is 30 .find the original number.
Answer:
X=36
Step-by-step explanation:
Let x be the unknown number
Three quarters of a number =3x/4
Three was added =3x/4 +3
Final
3x/4 + 3= 30
Multiply through with 4
3x+ 12=120
3x=120-12
3x=108
X=108/3
X=36
Can an equation with the variable inside grouping symbols be written as a two step equation
Answer:
yes
Step-by-step explanation:
In general, a linear equation with a variable anywhere can be written as a 2-step equation. (It may take several steps to get there.)
Example 1:
2(3x +3) = 18 . . . original equation with variable in parentheses
6x +6 = 18 . . . . . 2-step equivalent
Example 2:
4(x -9) +6 = 3(2x +17) . . . original equation
4x -36 +6 = 6x +51
-30 = 2x +51 . . . . . . 2-step equivalent
Answer:
Yes
Step-by-step explanation:
1. Solve each equation for x. a. X – 10 = 0

Is (5, 2) a solution to the equation y = 8x?
Hey there! I'm happy to help!
To satisfy this equation, the y value has to be 8 times the x.
If you multiply 5 by 8, you get 40, not 2, so this is not a solution. The point (5,40) would be.
Have a wonderful day! :D
All we need to do is substitute and check.
5 = x
2 = y
y = 8x
2 = 8(5)
2 does not equal 40
Best of Luck!

9x – 5 y = -12
-9x + 5y = 12
And show work pls
Answer:
9x – 5 y = -12
any point along this line
Step-by-step explanation:
9x – 5 y = -12
-9x + 5y = 12
Add the two equations
9x – 5 y = -12
-9x + 5y = 12
-------------------------
0x + 0y = 0
There are infinite solutions since the y are the same line

ABC shipping charges $7 plus $1 a pound to ship an overnight package. XYZ shipping charges $10 plus $0.75 a pound to ship an overnight package. For what weight is the charge the same for the two companies?
x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.

a flight overbooked by 4 passengers as a integer
Answer:
k
Step-by-step explanation:
The integer representing a flight overbooked by 4 passengers is given as -
k = x + 4
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is a flight overbooked by 4 passengers.
Assume that the total capacity of the flight is given by integer x.
Also assume that after over booked by 4 passengers, its capacity is given by integer k. So we can write the equation as -
k = x + 4
Therefore, the integer representing a flight overbooked by 4 passengers is given as -
k = x + 4

a water tank is draining at a constant rate if after five minutes the tank is drained by 4.5 gallons what is the rate in gallons per minute at the tank is draining
Answer:
The rate is 0.9 gallon per minute
Step-by-step explanation:
Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute
Let the amount drained per minute be x
4.5 gallons = 5 minutes
x gallon = 1 minute
Let’s cross multiply;
x * 5 = 4.5 * 1
5x = 4.5
x = 4.5/5
x = 0.9 gallons
