Answer:
4 solutions
Step-by-step explanation:
remember that y=mx+b
So 2/5x would be you m.And -3/7 is your b
Answer:
∠2 = 41°
Step-by-step explanation:
This is because, all three interior angles in a triangle will have a sum of 180 degrees.
So given that we have two angles, 90 degrees(right angle) and 49 degrees, we can replace angle 2 as our unknown value(a variable) and make it equal to 180 degrees then solve for x;
49 + 90 + x = 180
139 + x = 180
-139 -139
x = 41°, ∠2 = 41°
Answer:
<h2>r = 8</h2>
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the equation:
Therefore the center is (0, 0) and the radius r = 8
This is the quadratic formula.
