Answer:

(4+5-2+1)- (7+3-8+6) = 0

Step-by-step explanation:

you look for what numbers when subtracted equal zero (in this case each of the parentheses is 8) in each of the parentheses and combine them at the end to form the final equation.

Pls tell me what the correct answer would be ❤️

Answer:

Step-by-step explanation:

The error is in the second step. For some unknown reason, the x was dropped and the 3 was subtracted from the 7.

It should be

9x +3x + 12 = 7

12x + 12 = 7 Subtract 12 from both sides.

12x + 12 - 12 = 7 - 12 Combine

12x = -5 Divide by 12

12x/12 = -5/12

x = -5/12 or x = - 0.4167

Which function has a range of y < 3? y = 3 (2) Superscript x y = 3 (3) Superscript x y = negative (2) Superscript x Baseline

marusya05 [52]

Answer:

y = negative (2) Superscript x Baseline + 3

Step-by-step explanation:

An exponential function has a range of y > 0. In order for it to have a range of y < 3, it must be reflected across the x-axis (given a negative multiplier) and must be translated upward 3 units.

That is, for some exponential function y = b^x, you must have something of the form ...

y = -a·b^x +3

Only one answer choice has this form:

$\boxed{y=-2^x+3}$
