Answer:
A = 75°
B = 90°
C = 15°
Step-by-step explanation:
The diagram tells us that C = 15°.
The diagram places a square in the angle of B, showing you the angle is a 90° right angle.
You can solve for A because all angles of a triangle must equal 180°. 180° - 90° (B) = 90°. 90° - 15° (C) = 75°, the measure of A.
draw the triangle out and place all your given information in it to solve this.
Take 2 points
(3, 9) and (0, 3)
Slope = (Y2 -Y1) ÷ (X2 -X1)
<span>Slope = (3-9) / (0-3)
</span><span>Slope = -6 / -3
</span><span>Slope = 2
The equation will have the form </span><span>y = mx + b</span>
We can rearrange this to b = y -mx
Let's take one of the points (3, 9) and the slope (m) and enter it into the formula:
b = -9 -2*3
b= -3
Now we enter all that data into b = y -mx
and get
y = 2x -3
Answer:
-2x - 10
Step-by-step explanation:
-2 x X = -2x
-2 x 5 = -10
Put them together to get:
-2x - 10
Answer: All of the numbers in the sequence are going up twice the amount as before. The next three terms will be 208, 416, 832
