Answer:
2x + y = 18
y = 4x - 12
x = 5, y = 8
Step-by-step explanation:
x = 1st number
y = 2nd number
We can use the substitution method as we know what 'y' equals; that value will get plugged in for 'y' in the first equation as follows:
2x + 4x - 12 = 18
6x - 12 = 18
6x = 30
x = 5
y = 4(5) - 12 which is 20-12 or 8
y = 8
Time = distance / speed
time = (7/8) / (3/8)
= 7/8 * 8/3
= 7/3 or 2 1/3 minutes or 2 minutes and 20 seconds
Answer:
It could be (7,4)
Step-by-step explanation:
With the slope you go up 3 and 4 to the right
Answer:
From the General Equation of a straight line
Y=Mx + c
where M = Slope of the line
c= Intercept on Y axis
y=-4.2x-80
Comparing with the Eqn of a straight line
Slope = -4.2
From the Options the answers are in Fractions
You can easily convert this figure to fraction by Moving the decimal to the back once and then divide by 10
Then we have -42/10
Reducing Further
you have = -21/5.
