What is the difference when 5x2 − 3x + 2 is subtracted from 4x2 − 7x + 9?
Answers
Answer:
5-4x
Step-by-step explanation:
so when 10 - 3x + 2 is subtracted from 8 - 7x + 9
an important thing here is to remember the brackets as you minus something,
17 - 7x - ( 12 - 3x)
which gives 17 - 7x -12 + 3x
which then the difference yields .... 5 - 4x

Graham and Hunter are circus performers. A cable lifts Graham into the air at a constant speed of 1.5 ft/s. When Graham’s arms are 18 ft above the ground, Hunter, who is standing directly underneath Graham, throws Graham a ball as the cable continues to lift him higher. Hunter throws the ball from a position 5 ft above the ground with an initial velocity of 24 ft/s. Which system of equations can be used to model this situation?A) h=18+1.5th=5+24t-16t^2B) h=18+1.5th=5+24t+16t^2C) h=18+1.5th=5+24tD) h=18t+1.5t-16t^2h=5+24t-16t^2

Answer:
18 years
Step-by-step explanation:
Let Nick age is x years and Harry's age is y years.
Hence, we have the equation
x = 7y ......(1)
After six years, Nick's age is (x+6) and Harry's age is (y+6)
Hence, we have
Plugging x = 7y, we get
Hence, from equation (1)
x = 7(12)
x =84
In 6 years, Harry will be of 12 + 6 =18 years.
Nick's age is 7x
In 6 years Harry is 7x+6, and Nick is 5(x+6)
7x+6=5x+30
2x+6=30
2x = 24
x = 12
Harry = 12 years old and in 6 years Harry will be 18.

12 packages of banana chips ... 1 week = 7 days
x packages of banana chips = ? ... 1 day
12 * 1 = 7 * x
12 = 7 * x
x = 12 / 7
x = 1 5/7 packages of banana chips per day
The fraction would be 12/7 packages of banana chips per day.

Answer: y = 3x + 60
Step-by-step explanation:
Set up two equations and solve the system:
270 = 70x + b
- (150 = 30x + b)
120 = 40x
3 = x
Input "x" into one of the equations and solve for "b":
150 = 30x + b
150 = 30(3) + b
150 = 90 + b
60 = b
Equation: y = 3x + 60
This means that there is a flat fee of $60 plus a rate of $3 per student
The fixed rate of gym fee of $60 plus a rate of $3 per student.
The fixed-rate is;
Given
I rent a gym for $150.00 for 30 students.
Another time I rent the gym for $270.00 for 70 students.
Linear function;
A linear function is a function that forms a straight line in a graph.
Let x be the number of students and y be the total cost of renting the gym.
To find the fixed-rate let us write the equation of line representing the total cost of renting a gym for x students.
The equation representing a fixed rate is;
I rent a gym for $150.00 for 30 students.
Another time I rent the gym for $270.00 for 70 students.
Subtracting both the equations;
Substitute the value of x in equation 1
Therefore,
The fixed-rate is;
Hence, the fixed rate of gym fee of $60 plus a rate of $3 per student.'
