Answer:
A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane.
Step-by-step explanation:
The lines intersect at infinitely many points. (The two equations represent the same line.)
Answer:
x = -4/3 and x = 5/2.
Step-by-step explanation:
6x² - 7x = 20
6x² - 7x - 20 = 0
To solve this, we can use the quadratic formula to solve this.
[please ignore the A-hat; that is a bug]
In this case, a = 6, b = -7, and c = -20.
= 
= 
= 
= 
= 
= -8 / 6 = -4 / 3
= 
= 15 / 6 = 5 / 2
So, x = -4/3 and x = 5/2.
Hope this helps!
Answer:
1. Integer, rational, and real
Step-by-step explanation:
Remember:
(This is how my teacher taught it; yours may have done it differently)
Real numbers are numbers that can be plotted on a number line.
Rational numbers can be represented as a fraction (if they can't be represented as such they are irrational).
Integers are natural numbers, the opposite of natural numbers, and zero.
Whole numbers are natural numbers and zero.
Natural numbers are numbers you can count with.
-61 fits under real numbers, rational numbers, and integers. Assuming you want to be as specific as possible, the answer will be 1. Integer, rational, and real.
Answer: Hey there, your answer is 1/12
Step-by-step explanation: Steps to solve (steps will be in numerical order)
1. Find the lcd of the fractions, and the lcd for both problems will be 12.
2. To rewrite you have to multiply the numerator and denominator by three since the lcd is 12. So you're new fraction will be . For the second fraction, since the lcd is 12 you will multiply the numerator and denominator by 4. You're new fraction will be .
3. Since the problem contains the math keyword "Further", you automatically know you have to subtract, now subtract - . First, start of by subtracting the numerators, so subtract 9-8=1 , remember the denominators will always stay the same.
In conclusion, you're answer will be , so Isabel lives farther away from Janet.
