(f+g)x = f(x)+g(x)

Therefore,

\frac{x}{4}  - 3 +  {4x}^{2}  + 2x - 4 \\ 4 {x}^{2}  + ( \frac{x}{4}  +  \frac{8x}{4} ) - 7 \\ 4 {x}^{2}  +  \frac{9x}{4}  - 7

Therefore, the answer is B.

Jason begins at the start of a path and rides his bike 11 12 miles on the path. The path is 12 14 miles long. Enter the distance
nikitadnepr [17]

Answer:

Number of miles remaining for Jason to reach end of the path = 3/4 miles

Step-by-step explanation:

Total distance of the path = 12 1/4 miles

Distance reached by Jason's bike on the path = 11 1/2 miles

Enter the distance, in miles, Jason must ride to reach the end of the path.

Number of miles remaining for Jason to reach end of the path = Total distance of the path - Distance reached by Jason's bike on the path

= 12 1/4 miles - 11 1/2 miles

= 49/4 - 23/2

= (49-46) / 4

= 3/4 miles

Number of miles remaining for Jason to reach end of the path = 3/4 miles

Equation M: y = 3x + 4
solmaris [256]
Y = 3x + 4
y = 3x + 7

3x + 4 = 3x + 7
3x - 3x = 7 - 4
0 = 3.....incorrect....this system has no solutions because ur lines are parallel and they never cross.

or look at it this way..
y = 3x + 4
y = 3x + 7

both have slopes of 3...but the y intercepts are different......when this happens, it means the lines are parallel with no solution

Adult panda weights are normally distributed with a mean of 200 pounds and a standard deviation of 20 pounds. The largest pandas
earnstyle [38]
\mathbb P(X>250)=1-\mathbb P(X\le250)

\mathbb P(X\le250)=\mathbb P\left(\dfrac{X-200}{20}\le\dfrac{250-200}{20}\right)=\mathbb P(Z\le2.5)\approx0.9938

which means

\mathbb P(X>250)\approx1-0.9938=0.0062

so approximately 0.62% of pandas weight over 250 pounds.
