Answer:
Step-by-step explanation:
The Pythagorean theorem tells us that , where a and b are the legs of a right triangle. If the length of each leg is x, we know by applying the theorem that , so . Applying the square root on both sides we get
Answer:
B
Step-by-step explanation:
It cannot be C. The Y-intercept of Function W is 30, while the Y-intercept of Function Z is 15.8. Now, we are left with A, B, and D.
It cannot be D, because 30 is not less than 15.8. Now, we are left with options A and B.
Function Z as an equation is approximately y=-1/24x+15.8.
The slopes are NOT equal, so the answer cannot be A.
Explanation why it's B:
1/16 is bigger than 1/24, however, since the fractions are NEGATIVE, -1/16 is actually LESS THAN -1/24. The slopes of Function W is less than the slope of Function Z.
1. -7×3t−7×−9
2. -21t−7×−9
3. -21t−(−63)
Answer:
-21t + 63
