5x + 50 +x
= 5x*2( square ) + 50
Let P(a, b) be a point on the coordinate plane. Then the following hold:
i) If a>0, b>0 then P is in the I.Quadrant.
ii) If a<0, b>0 then P is in the II.Quadrant.
iii) If a<0, b<0 then P is in the III.Quadrant.
iv) If a>0, b<0 then P is in the IV.Quadrant.
v) If a=0 and b is positive or negative, then P is on the y-axis.
vi) If b=0 and a is positive or negative, then P is on the x-axis.
Since we have: a=0, and 19 positive, then this point is on the y-axis.
Answer: y-axis
Answer:x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':
Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7
Answer: 5.5 hours
Step-by-step explanation:
distance/speed = time
330/60 = 5.5
Answer:
As shown in picture, AC is tangent to circle O
=> angle BAC = 90 deg
As the property of angle on circle:
=> BAY = (1/2) arc BY = (1/2) x 52 = 26 deg
=> angle YAC = angle BAC - angle BAY = 90 - 26 = 64 deg
Hope this helps!
