12= 1/3*x 12= x/3 36=x Hoje ela tem 4 anos, daqui a 8 anos terá 12 anos, que é um terço da idade de seu pai, 12*3=36
Answer: 24? =)
Step-by-step explanation:
A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
Answer:
4 cents
Step-by-step explanation:
4.50 divide by is .9 and 7.52 divide by 8 is .94
Answer:
4(5x + 6)
Step-by-step explanation:
To start, let's expand things out, as we cannot learn anything from this form. We get 30x + 20 - 10x + 4, or 20x + 24. To find the GCD (Greatest Common Divisor), we take the terms and try to find the number (or term) that divides them. It must be a constant, because of the 24, and 4 goes into 20 and 24. So, our final answer is 4(5x + 6).
