At 2:00pm a car's speedometer reads 20mph, and at 2:10pm it reads 30mph.
Dmitry [639]

Over this 10-minute interval, the car's average acceleration is

\dfrac{30\,\mathrm{mph}-20\,\mathrm{mph}}{10\,\mathrm{min}}=\dfrac{10\,\mathrm{mph}}{\frac16\,\mathrm h}=60\dfrac{\rm mi}{\mathrm h^2}

The MVT says that at some point during this 10-minute interval, the car must have had an acceleration of 60 mi/h^2.

Solve the following equation by transforming it into a perfect square trinomial.* 3x2 + 12x = 63
Eddi Din [679]
3x^2 + 12x = 63\\ \\3x^2+12x-63=0\\ \\3(x^2+4x-21)=0\\ \\3[x^2+4x+3x-3x-21] =0 \\ \\3[x^2+7x-3x-21] =0 \\ \\3[x(x +7 )-3(x+7)] =0

3 (x +7 ) (x-3) =0 \\ \\x+7=0 \ \ \ or \ \ \ x-3 =0\\ \\x=-7 \ \ \ or \ \ \ x=3

arlik [135]

The slope (m) is the change in Y over the change in X.

Slope = Y/X

The slope is given as -3/4 , so y would be 3 and X would be 4.

Y = 3
