Help please I would appreciate it !
MAXImum [283]

Answer/Step-by-step explanation:

Given:

Line equation => 2.1x + 9.9y - 9.2 = 0

Required:

x-intercept and y-intercept of the line.

SOLUTION:

The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.

2.1x + 9.9(0) - 9.2 = 0

2.1x + 0 - 9.2 = 0

2.1x - 9.2 = 0

2.1x - 9.2 + 9.2 = 0 + 9.2

2.1x = 9.2

\frac{2.1x}{2.1} = \frac{9.2}{2.1}

x = 4.4 (approximated)

The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.

2.1(0) + 9.9y - 9.2 = 0

9.9y - 9.2 = 0

9.9y - 9.2 + 9.2 = 0 + 9.2

9.9y = 9.2

y = \frac{9.2}{9.9}

y = 0.9 (approximated)

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!<br><br> Simplify.
True [87]

Answer:

(B): (x - 2)/(x + 1)

Step-by-step explanation:

The numerator is x^2 + 5x - 14. That is equal to (x - 2)(x + 7).

The denominator is x^2 + 8x + 7. That is equal to (x + 1)(x + 7).

You can then eliminate (x+7) to get (x - 2)/(x + 1).
