There is two angles if angle

Add 1 on both sides, so the one cancels on the left. You are left with w < 4. Draw a line and write a 4. Place an open circle where the 4 is one the line and draw an arrow starting at the open circle that is heading towards the left.

Why is the arrow moving to the left?
Because w < 4 means that the value of “w” will be numbers that are less that 4. On a number line, that would be numbers going to the left of four.

BRAINLIEST PLUS 38 POINTS

Answer:

8b is 220

Step-by-step explanation:

it might be 220 because we already know that from o to b is 140 degrees. We know that a full circle is 360, so take 140 away from 360, and you get 220.

360-140=220 degrees

Im not sure about the other questions but i hope this helps :)

The linear function f(x) = 0.9x + 79 represents the average test score in your math class, where x is the number of the test tak

Levart [38]

Given:

The linear function for average test score in your math class is

$f(x)=0.9x+79$

where x is the number of the test taken.

The linear function g(x) in the given table represents the average test score in your science class, where x is the number of the test taken.

To find:

Part A: The test average for your math class after completing test 2.

Part B: The test average for your science class after completing test 2.

Part C: Which class had a higher average after completing test 4?

Solution:

Part A:

We have,

$f(x)=0.9x+79$

Put x=2 in the above function, to find the test average for your math class after completing test 2.

$f(2)=0.9(2)+79$

$f(2)=1.8+79$

$f(2)=80.8$

Therefore, the test average for your math class after completing test 2 is 80.8.

Part B:

From the given table it is clear that g(x) =79 at x=2.

Therefore, the test average for your science class after completing test 2 is 79.

Part C:

Put x=4 in f(x), to find the test average for your math class after completing test 4.

$f(4)=0.9(4)+79$

$f(4)=3.6+79$

$f(4)=82.6$

From the table it is clear that the value of g(x) is increased by 1 as x is increased by 1. So, the value of function g(x) at x=4 must be 1 more than 80.

$g(4)=81$
