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!

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
143
Now use 13 as x
6(13)+3

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

any point along this line
Step-by-step explanation:
9x – 5 y = -12
-9x + 5y = 12
Add the two equations
9x – 5 y = -12

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
