Slope = rise/run = (change in y)/(change in x)
Slope = (4-6)/(0-(-4)) = (-2)/(4)
Slope = -1/2 = -0.5
Answer:
- 4x + 36
Step-by-step explanation:
(
- 6)² = ( - 6)( - 6)
Each term in the second factor is multiplied by each term in the firs t factor, that is
( - 6) - 6( - 6)
Distribute both parenthesis
= - 2x - 2x + 36 ← collect like terms
= - 4x + 36
Answer:
Step-by-step explanation:
1 kilometer = 1000 meters.
Multiply total kilometers by 1000:
108 kilometers x 1000 = 108,000 meters.
1 hour = 3600 seconds.
Divide total meters by 3600:
108,000 / 3600 = 30 meters per second
Multiply 30 meters per second by 15 seconds:
30 x 15 = 450 meters in 15 seconds.
To solve this equation, first we have to use the distributive property to eliminate the parentheses on the left side of the equation.
If done correctly, your simplified equation should be
100,000 + 75,000x = 125,000
Next, we would subtract 100,000 from both sides, resulting in the equation
75,000x = 25,000
Finally, we would divide both sides of the equation by 75,000, resulting in your final answer of
x= 25,000/75,000
However, many mathematics teachers ask for fractional answers to be simplified. To simplify fractions, we first find the GCF of both numbers, and then divide both the numerator and the denominator by the GCF.
The GCF of 25,000 and 75,000 is 25,000.
So, in simplest form, your final answer is
x=1/3
