Can someone can help me solve this inequality?
12345 [234]

Answer:

b < -10  and  (-∞, -10)

Step-by-step explanation:

I won't draw the number line but I will do the interval notation.

Interval notation is a way to describe infinite or finite sets with numbers.

To solve the inequality first add 2 to both sides to get:

-b > 10 Multiply both sides by -1:

b < -10 is the simplification of the inequality .

Now to write this in interval notation you need to know which direction the values are increasing, since b is less than -10, the values are going down starting from -10 (not including -10).

Interval notation: (-∞, -10)

The length of a rectangle is 10 yd less than three times the width, and the area of the rectangle is 77 yd^2. Find the dimension
oksano4ka [1.4K]

Answer:

width = 7, length = 11

Step-by-step explanation:

area = 77

length = 3w - 10

width = w

w(3w - 10) = 77

3w^2 - 10w - 77 = 0

(3w + 11)(w - 7) = 0

we rule out 3w + 11 = 0 because w would be negative

so we use w - 7 = 0

so the width = 7

length = 3w - 10

length = 21 - 10

length = 11
