You would multiply 2 1/2 and 3 3/4, which would give you 9.375 or as a mixed number 9 7/8
Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.
THEOREM:
- <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
ANSWER:
By pythagorean property,
- x² = 12² + 9²
- x² = 144 + 81
- x² = 225
- x = √225
- x = 15 units.
So, <u>Correct choice</u> - [C] 15 units.
Answer:
a^2 = c^2 - b^2
to get A though you need to take the square root.
Step-by-step explanation:
you need to rearrange the formula to get a by itself.
c^2 = a^2 + b^2
a^2 = c^2 - b^2
to get A though you need to take the square root.
O+6-2O=-8
subtract 6 from both sides
the equation is then O-2O=-14
combine like terms on the left side
the equation is then -O=-14
divide by -1
final answer is O=14
