Answer:
11j - 1573/10
Step-by-step explanation:
J = 10v /11 +143
collect terms
J - 143 =10v /11
11 (J -143) = 10v
Divide both sides by 10
11(J - 143)/10 = v
v = 11J - 1573/10
Hope this helps!
Answer:
The 3rd quadrant, where the x and y are both negative.
Answer:
7.
Step-by-step explanation:
The equation of a circle is
(x - h)² + (y - k)² = r²
Where
(h, k) is the center and r is the radius, so we only need to work with r.
The expression states that
r² = 49 or the radius squared is equal to 49. So solve for r to find the radius.
r² = 49
Take the square root.
r = 7
The radius of the equation is 7.
Angle at Y = 180-135 = 45, because it divides the straight line XY in two pieces that together should always be 180
Angle at Z = 49, because the angle on the other side of Z is mirrored.
Angle YXZ = 180 - 49 - 45 = 86 because all three angles of a triangle should add up to 180
