Answer:
[tex]m = \frac{11}{12} [/tex]
Step-by-step explanation:
m= (y2-y1) / (x2-x1)
m = 19 - (-3) / 19 - (-5)
m = 22 / 24
m = 11/12

The slope of the line represented by y = 5x is
Answer:
The slope of the line represented by y = 5x is 5
Step-by-step explanation:
The form of the linear function is y = m x + b, where
m is the slope of the line that represents the equationb is the y-intercept (the value of y at x = 0)To find the slope of a line from its equation compare the equation with the form of the linear function, then find the coefficient of x which is the slope of the line
∵ The equation of the line is y = 5x
→ Compare it with the form of the equation above
∵ The coefficient of x = 5
∴ m = 5
∴ The slope of the line represented by y = 5x is 5

Jason claims he has finished reading 25% of his book. If his book has 200 pages, how many pages has he read?
Answer:
Jason has read 50 pages.
Step-by-step explanation:
25% of 200 = 50
Remember "of" means multiply so you multiply 25% to 200
25% x 200
Convert 25% into a decimal
0.25 x 200 = 50
So Jason has read 50 pages.
21. Given that f(x)= x^3– x² + 5x and g(x)= x^3 +5x^2 –2 determine

Answer:
(g - f)(x) = 6x² - 5x - 2
General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining Like TermsStep-by-step explanation:
Step 1: Define
f(x) = x³ - x² + 5x
g(x) = x³ + 5x² - 2
(g - f)(x) is g(x) - f(x)
Step 2: Evaluate
Substitute: (g - f)(x) = x³ + 5x² - 2 - (x³ - x² + 5x)Distribute -1: (g - f)(x) = x³ + 5x² - 2 - x³ + x² - 5xCombine like terms: (g - f)(x) = 6x² - 5x - 2How do you convert r=8 cos(θ) into cartesian form?
An industrial engineer must estimate the cost of building a storage tank. The tank requires 208 sq ft of material at $9.29 per square foot. It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour. Find the total cost of the tank.
Answer:
The total cost of making the tank equals $2,082.48
Step-by-step explanation:
Giving the following information:
The tank requires 208 sq ft of material at $9.29 per square foot.
It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour.
To calculate the total cost, we need to multiply the unitary variable cost by the total amounts:
Direct material= 9.29*208= $1,932.32
Direct labor= 4.5*26.4 + 1.6*19.6= $150.16
The total cost of making the tank equals $2,082.48

Find all real numbers x that satisfy the equation (x-4)(x-8) = 12.
Answer:
x=10
Step-by-step explanation:
(10-4)(10-8) = 12
(6)(2) =12
12 = 12
The required real number that satisfies the given expression is x=10, x= 2.
Given that,
To determined the real numbers x that satisfy the equation (x - 4)(x - 8) = 12
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
(x - 4)(x - 8) = 12
x²-12x+32=12
x²-12x+20=0
(x - 10)(x -2) = 0
Thus, the required real number that satisfies the given expression is x=10, x= 2.

A scuba diver is swimming 15 feet below the water’s surface.
The diver swims up slowly at 0.5 feet per second for 4 seconds; and then stops to look at an eel. Finally, the diver swims up for 3 more seconds at 0.4 feet per second. What is the diver’s new depth?
Answer: -11.8 = 11.8 feet below the water's surface

Answer:
.5 or 1/2
Step-by-step explanation:
Y^2x 24^2=25^2
Y=7
7=14x
x=.5
The value of x is 0.5.
The calculation is as follows:Here we use Pythagoras Theorem
[tex]Y^2 - 24^2=25^2[/tex]
Y=7
Now
7 = 14x
So, x=.5
Therefore we can conclude that The value of x is 0.5.

A variable needs to be eliminated to solve the system of equations below. Choose the
correct first step.
- 4x – 2y = 18
4x – 4y = -36
O Subtract to eliminate x.
O Subtract to eliminate y.
O Add to eliminate x.
O Add to eliminate y.
Step-by-step explanation:
-4x - 2y = 18
+ (4x - 4y = -36)
=> -6y = -18, y = 3
As we added the equations together, we have eliminated x and found y.
Hence the correct answer is "Add to eliminate x".
