What is 9c+90<-27?????

antoniya [11.8K]

<h3>Answer: c < -13</h3>

========================================

Work Shown:

9c + 90 < -27

9c + 90 - 90 < -27 - 90 .... see note 1

9c < -117

9c/9 < -117/9 ... see note 2

c < -13

-----------

note 1: I'm subtracting 90 from both sides to undo the "plus 90" that is happening on the left side

note 2: I divided both sides by 9 to undo the multiplication. The expression 9c is the same as 9*c or "9 times c". The inequality sign will <u>not</u> flip as we are dividing both sides by a positive number.

Find the gradients of lines A and B.

pishuonlain [190]

Answer:

Gradient of line A = 4

Gradient of line B = -2

Step-by-step explanation:

To solve this question, we will use the formula for gradient passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ ,

Gradient (m) = $\frac{y_2-y_1}{x_2-x_1}$

For line A,

Since, line A passes through (3, 6) and (4, 10)

Gradient of line A = $\frac{10-6}{4-3}$

= 4

For line B,

Since, line B passes through (1, 6) and (2, 4),

Gradient of line B = $\frac{6-4}{1-2}$

= -2
