Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
Answer:
It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.
Step-by-step explanation:
Points:
Slope-intercept form:
slope is:
- m= (y2-y1)/(x2-x1)= (20-10)/(7-7)= 10/0,
denominator of the fraction is zero, we can't divide by zero, so this line has no slope
----------
It has a slope of zero because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the numerator of a fraction cannot be zero.
- no, numerator is not zero

3 cans!!!
5x6= 30 (divided by 2= 15)
5x6=30 (divided by 2 = 15)
10x18= 180
180+30= 210

Express each ratio as a fraction in simplest form.2 yards to 45 feet
First, let's convert feet to yard to get the answer
=> 2 yard = x yard
=> 1 foot = 0.333333 yard.
=> 0.333333 yard * 45 = 15 yards, thus the answer is
