Which inequality is true 1.5 > 2 1/2, 1/2 > 0.5, -2.5 > -1.5, -3 1/2 > - 4.5

yawa3891 [41]

Answer: D

Step-by-step explanation:

(A. 1.5 > 2 1/2

(B. 1/2 > 0.5

(C. -2.5 > -1.5

(D. -3 1/2 > - 4.5

Step 1: Convert everything to decimals or fractions so its easier to see and make it less likely to get the question wrong

Method #1: Fractions

1.5= 1 1/2

0.5= 1/2

-2.5= - 2 1/2

-1.5= - 1 1/2

-4.5= -4 1/2

Now we have:

(A. 1 1/2 > 2 1/2 --> This is wrong because 1 1/2 is supposed to be less than 2 1/2.

(B. 1/2 > 1/2 This is also wrong. 1/2 is equal to 1/2; they are obviously the same.

(C. -2 1/2 > -1 1/2 This is wrong because, in negative numbers, its sort of backwards. For example, -2 is actually less than -1 because its farther away from 0. But if they were normal positive numbers, 2 would be bigger. But here, -2 1/2 is less than -1 1/2.

(D. -3 1/2 > - 4 1/2 This is correct. -3 1/2 is closer to 0 than -4 1/2, so it has to be bigger.

Solving the problem this way gets me to: Answer= D

Method #2: Decimals (remember: same numbers, different way of writing them!!!)

(A. 1.5 > 2.5 False. 1.5 is less than 2.5

(B. 0.5 > 0.5 False. 0.5 is equal to 0.5

(C. -2.5 > -1.5 False. -2.5 is farther away from 0 so its actually smaller.

(D. -3.5 > - 4.5 True. -3.5 is closer to 0.

Doing it this way also leads me to Answer= D.

Hope this helps :)) Also can i please have brainiest? I worked pretty hard on this :D

Can someone help with this please?

Answer:

a. Function 1

b. Function 2

c. Function 4

Step-by-step explanation:

✔️Function 1:

y-intercept = 4 (the point where the line cuts across the y-axis)

Slope, using the two points (0, 4) and (1, 6):

$\frac{y_2 - y_1}{x_2 -x_1} = \frac{6 - 4}{1 - 0} = \frac{2}{1} = 2$

Slope = 2

✔️Function 2:

y-intercept = 1 (the value of y when x = 0)

Slope, using the two points (0, 1) and (1, -3):

$\frac{y_2 - y_1}{x_2 -x_1} = \frac{-3 - 1}{1 - 0} = \frac{-4}{1} = -4$

Slope = -4

✔️Function 3: y = 5x - 5

y-intercept (b) = -5

Slope (m) = 5

✔️Function 4:

y-intercept = -2

Slope = -1

Thus, the following conclusions can be made:

a. The function with the greatest y-intercept is Function 1 which is 4.

4 is greater than 1, -5, and -2.

b. Only Function 2 has slope that is less than -2.

-4 is less than -2.

2, 5, -1 are all greater than -2.

c. The function's graph with the least steep is the function whose slope value is the smallest. That is the greater the absolute value of the slope, the steeper the slope, and vice versa.

Function 4 has the least steep.
