Answer:
(5,8) over y axis and (-5,-8) over x axis
Step-by-step explanation:
Hi!
Tip #1: To multiply polynomials, consider the variables separate from the numbers.
So we are multiplying 2xyz * -4x²yz
Let's start by multiplying the variables.
xyz * x²yz
Tip #2: The exponents tell you how many of each variable there are. When multiplying variables, add the exponents. When a variable does not seem to have an exponent, that means there is an invisible exponent of 1! (x =
)
xyz * x²yz = (x + x²)(y + y)(z + z) = x³y²z²
Now multiply the numbers! (just like normal)
2 * -4 = -8
Now combine the numbers with the variables once again.
-8x³y²z²
The answer for 2xyz * -4x²yz is -8x³y²z²
Hope this helps! :)
Answer:
The answer to your question is number 3.
Step-by-step explanation:
Data
slope = m = 2
Point = (3, 9)
Process
1.- Write the equation of the line in the form point-slope
y - y1 = m(x - x1)
2.- Identify the values of x1 and y1
x1 = 3 y1 = 9
3.- Substitution
y - 9 = 2(x - 3)
4.- Simplify
y - 9 = 2x - 6
y = 2x - 6 + 9
5.- Result
y = 2x + 3 slope y-intercept form
Remark
Start by figuring this out for 1 car. Worry about the 7 part when you find 1.
This problem is used quite frequently in physics. For example resistors in parallel use the same equation.
Formula
1/frank + 1/carla + 1/missy = 1/ time taken to do 1 mar.
Givens
Frank = 2 hours
Carla = 2 hours
Missy = 3 hours.
Substitute and Solve
1/2 + 1/2 + 1/3 = 1/Three_together.
3/6 + 3/6 + 2/6 = 1/Three_together.
8/6 = 1/Three_together. Cross multiply
8 * Three_Together = 6*1
8 * Three_Together = 6 Divide by 8
Three_Together = 6/8 = 3/4 = 0.75 hours. or 45 minutes for 1 car
Seven Cars
For 7 cars multiply 0.75 by 7
7 * 0.75 = 5.25 hours. <<<< Answer
