Desmos comes in handy with these problems. Use the "FOIL" method for each of them and then plug them into the calculator of desmos. This will graph each other them. Note the x and y axis'
Example for (A) y= (x-2)(x+3) foil it:
x^2+3x-2x-6
x^2+x-6
plug that in and match to graph.
In mathematics, the additive inverse of a number a is the number that, when added to a yields zero. This operation is also known as the opposite (number), sign change, and negation. ... For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0 .
One number is four more than a second number. Two times the first number is 12 more than four times the second number. Solve. the answer is 12
Answer:
2720 feet
Step-by-step explanation:
u can draw a right triangle whose opposite side is 1700 feet, the adjacent side is the ground distance from Charlie to the plane (x), and the angle between theses sides is 32°.
Then, tan (32°) = 1700 feet / x => x = 1700 feet / tan(32°) = 1700 feet / 0.625 = 2720 feet.
