Slope of the line is -3/2

Step-by-step explanation:

Step 1: Given that (-2, 4) is a point on the line y = mx + 1, find slope m.

Since the point is on the line, the coordinates will satisfy the equation.

⇒ 4 = m × -2 + 1

⇒ 4 = -2m + 1

⇒ 3 = -2m

∴ m = -3/2

The correct answers for this question are these:
2 < x < 3
and
−3 < x < -2

As you can see in the given graph, there are two intervals that the line is increasing. Increasing graph is when the line rises from left to right. In the graph, the first increase in graph is -3 < x < -2 and the other one is at the last part 2 < x < 3

Does someone mind helping me with this problem? Thank you!

Grace [21]

Step-by-step explanation:

∠A + ∠B + ∠C = 180°

Here the value of ∠B and C is given below...we need to find the value of ∠A ....

a + 120° + 40° = 180°

a + 160° = 180°

a = 160° - 180°

a = 20°

Murrr4er [49]

The four books had an average of 341 pages

Step-by-step explanation:

Given

Total number of books = 4

Pages in first book = x1 = 326

Pages in second book = x2 = 288

Pages in third book = x3 = 349

Pages in fourth book = 401

The average is given by:

$Average=\frac{Sum\ of\ pages}{number\ of\ books}\\=\frac{x_1+x_2+x_3+x_4}{4}\\=\frac{326+288+349+401}{4}\\=\frac{1364}{4}\\=341$

The four books had an average of 341 pages
