Answer:
The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I
Step-by-step explanation:
To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.
8x + 6y = 48
4x - 6y = -12
-------------------
12x = 36
x = 3
Next, find the y value by plugging in the x value to either equation and solving.
2x - 3y = -6
2(3) - 3y = -6
6 - 3y = -6
-3y = -12
y = 4
Answer:
5 years
Step-by-step explanation:
1. if able's age is x, then his sister's is x-4, and his brother's is 2x
2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32
3. now solve for x, 4x-4=32, 4x=36, x=9
4. if able's sister is x-4 years old, she is 9-4, or 5 years old
Answer:
Step-by-step explanation:
I took the test is =33
Step-by-step explanation:
Part A:
In math, the word "of" means "multiplied by".
So if the elevation of city D is 1/4 of the elevation of city C, then our equation is 1/4*C, or C/4
Part B:
But we already know that C = 24, so we can just plug in 24 for C in our equation:
24/4 = 6 feet
Explanation: The answer is positive because when you're dividing two positive integers, there's no possible way to get a negative number.
Step-by-step explanation:
if 25 is an answer, its that
