It has become somewhat fashionable to have students derive the Quadratic Formula themselves; this is done by completing the square for the generic quadratic equation ax2 + bx + c = 0. While I can understand the impulse (showing students how the Formula was invented, and thereby providing a concrete example of the usefulness of abstract symbolic manipulation), the computations involved are often a bit beyond the average student at this point.
Answer:
Complete this sentence: in a triangle, the angle with the smallest measure is always opposite the <u><em>shortest side</em></u>.
Answer:
Step-by-step explanation:
In the first column, put days at the top and pounds at the bottom.
So Day 1 = 75 pounds, Day 2=150 pounds, Day 3 = 225 pounds, etc..
Answer: 4x'6
Step-by-step explanation:
Simplify x5
/8. Than, Equation at the end of step 1 : x5 ——) • x)1) ÷ 4 8
Step 2 : 2.1 16 = 24 (16)1 = (24)1 = 24 2.2 x6 raised to the 1 st power = x( 6 * 1 ) = x6
Step 3 : 24x6 Simplify ———— 4
Dividing exponents : 3.1 24 divided by 22 = 2(4 - 2) = 22
which brings us to our final answer above
Answer:
Let "x" be the number of people who can go to the amusement park.
So we have: 19 + 14x ≤ 180. This inequality basically means that the parking cost plus the cost of the tickets for every person cannot cost more than 180 dollars.
Solving this inequality, we get:
19 + 14x ≤ 180
14x ≤ 161
x ≤ 11.5
Obviously, we know that we can't have "half" a person, so the most people who can come to the amusement park would be 11 people, and the answer would be: x ≤ 11
Hope this helps!
