Whats the upper bound for estimate for 354 + 267?

1 answer:

7 0

Personally I'd replace 354 with 360 and 267 with 270, and then add 360 and 270, obtaining 630. Similarly, estimate 63.75 + 3.63 by adding 60 and 3: 63. There's no single answer for either problem. For "upper bound," I round the given addends upward; for "lower bound," I found the addends down.

Which of the following statements is correct Athe product of 3/4 and 7/8 is less than 7/8 B the product of 1/3 and 9/10 is less

dedylja [7]

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

PLEASE HELP Graph the ordered pairs for y = 3x + 3 using r = {-2, 1, 2}.

Fed [463]

Answer:

(-2, -3), (1, 6), (2, 9) are plotted in the attached graph

Step-by-step explanation:

For x = -2, y = 3(-2) +3 = -3. The ordered pair is (-2, -3).

For x = 1, y = 3(1) +3 = 6. The ordered pair is (1, 6).

For x = 2, y = 3(2) +3 = 9. The ordered pair is (2, 9).

The graph is attached.

Which shows a function that is decreasing over its entire graph? Working on it now need ASAP

PtichkaEL [24]

One thing everyone always forgets is we don't usually see the entire graph. Once out of the frame, these functions can do anything they want.

From what we can see, only the bottom right one is always decreasing.

Answer: bottom right

By the way, the top right graph (a vertical line) isn't a function.
