The answer is y = 3x - 2. To find slope, you subtract y2 - y1 and x2 - x1. In this case, y2 - y1 = 10 - 4 and x2 - x1 = 4 - 2. You would result in 6/2, which can be reduced to 3. Your slope is 3, so the first and second answer automatically are eliminated. Next, you could either draw it out on a coordinate plane or just visualize it. The starting point that goes through each line would be -2, which means D, or y = 3x - 2, is the correct answer.
Answer:
Billie's age = x = 17 years
Tony's age = y = 31 years
Step-by-step explanation:
Let
Billie's age = x
Tony's age = y
Twice Billie’s age decreased by 3 is Tony’s age.
y = 2x - 3..... Equation 1
Tony is fourteen years older than Billie.
x = y - 14
We substitute y - 14 for x in Equation 1
y = 2x - 3..... Equation 1
y = 2(y - 14) - 3
y = 2y - 28 - 3
y - 2y = -28 - 3
-y = -31
y = 31 years
Solving for x
x = y - 14
x = 31 - 14
x = 17 years.
Therefore:
Billie's age = x = 17 years
Tony's age = y = 31 years
3.65 e8
Step-by-step explanation:
The scientific notation e mean ‘10 raised to a particular power’. Therefore e8 is equivalent to 10 ^ 8.
We count the number of tens to the decimal point. In this case;
365000000
3.65000000
The decimal is <u>8</u><u> place values </u>from the right (since this is a whole number)
Answer:
Step-by-step explanation:
Isolate the term of x from one side of the equation.
<h3>x-5≤10</h3>
<u>First, add by 5 from both sides.</u>
<u>Solve.</u>
<u>Add the numbers from left to right.</u>
- <u>Therefore, the solution is x≤15, which is our answer.</u>
