The graph shows the altitude of a helicopter over time. a graph measuring altitude and time. a line runs through coordinates (0, 10,000) and (15, 4000) and shows a decrease in altitude as time increases what is the slope of the line and what does it mean in this situation? the slope is –2000 . this means that the helicopter descends 2000 ft each minute. the slope is –400 . this means that the helicopter descends 400 ft each minute. the slope is 400. this means that the helicopter ascends 400 ft each minute. the slope is 2000. this means that the helicopter ascends 2000 ft each minute. 1 2 3 4 5

We can calculate for the slope of the line using the formula:

m = (y2 – y1) / (x2 – x1)

From the given values:

m = (4,000 – 10,000) ft / (15 – 0) min

m = -400 ft/min

This means that the altitude is decreasing by 400 ft per minute.

> The slope is –400 . This means that the helicopter descends 400 ft each minute.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
