3x + (x - 0.75x)
4x - 0.75x
x= cost of the frame
This describes a parabolic path that starts at x=0 on a value of y = -5.1. That's when the rock is below ground in the hole. To find the answer we need to know the second x axis crossing. The first is when it is rising and reaches ground level, the second is after it peaks and falls back to the ground and lands. Using the quadratic formula I get the two zeros of this function to be about
x= 15.29, and 66.71. The rock then lands 66.71 feet from him horizontally.
Answer:
30
Step-by-step explanation:
6 papers per hour • 5 hours of work = 30 papers done in 5 hours.
If I need to go further, it would take 11 hours to grade all the papers because 6 • 11 = 66.
12• (0.25) • (-8) ÷ 1/3 • 5
3• (8) ÷ 1/3 • 5
24 • 1/3 • 5
8 • 5
40
Until the second step is ok.
in the third step, she multiplied the 1/3 term instead if dividing it
24 ÷ 1/3 . 5
24 ÷ 5/3
72/5
Answer:
y= -4x +3
Step-by-step explanation:
equation of slope -intercept is
y=mx+b
the slope of the equation that is perpendicular to the given line is negative reciprocal of the slope of this line y = (1/4)x +11 so slope is m= -4
point (2, -5)
equation given a point and a slope is
y +5 = -4(x -2)
y +5 = -4x +8
y= -4x +8-5
y= -4x +3
