If the first increase was 50%, that means that the price between the first and the second increase is 150% of the original. And as you need 6 (which is 4*150%) times the original, the price was increased for 450%. So, the last peecent increase is
It might be C. I used the process of elimination, so I'm not so certain
Answer:
1. The equation that represent the distance (d) that a person can run in t hours is: d = 4t
2. The equation is: c = $0.98(20)
3. The equation is: L = 18(5)
Step-by-step explanation:
1. The variable d represents the distance over time, and t represents the hour in the equation so if you want to find the distance over time, you would say distance per hour. The per means to multiply, so every distance is equal to 4 miles per hour..
2. If the teacher wants to find out how much she will have to pay for 20 chocolate bar, she has to substitute 20 into the equation to replace b, which means bar. So the equation would be: total cost (c) = $0.98 × chocolate bars (b). Once substituted, the equation will be c = $0.98(20).
3. The problem said "mows 18 lawns per day" and "mow in 5 days", that means that you substitute 5 into the equation to replace the d in days, since you are multiplying 5 × 18.. Your new equation will be: L = 18(5), Total Lawns = 18 (lawns) per 5 (days).
A) Slope: (y2 - y1) / (x2 - x1)
You can use point (-1, -6) and (0, -8)
Slope = (-8 - -6) /(0 - -1) = (-8+6)/(0+1) = -2/1 = -2.
Slope = -2.
b) Point (0, -8) is the point such that x = 0, and y = -8, this point represents the vertical intercept of the equation. The point where the line cuts the y axis.
Answer:
The lowest whole number must be 2 to make the comparison true...hope it helps:)
