Ok so I will take this from the top, lets start out with choice A (-1,-12) we will need to see if the answer is equal to A. so first lets just merge these two problems into eachother to get 4x-8=2x-10 now, after subtracting 2x from each side we get 2x-8=-10. Now, add 8 to both sides which will give us 2x=-2... now it is simple, just divide -2 by 2 to get an answer for x as -1...Answer A is the correct answer

Find the critical numbers (x-values) of the function y equals 2 x to the power of 5 plus 5 x to the power of 4 minus 19. Enter y

Zolol [24]

Answer:

$x=0,x=-2$

Step-by-step explanation:

From the question we are told that:

$y=2x^5+5x^4-19$

Generally the equation if differentiated is mathematically given by

$y'=10x^4+20x^3-0$

Where

y'=0

$10x^4+20x^3=0$

Factorizing,We have

$x=0,x=-2$

Therefore

The critical points are

$x=0,x=-2$

P(A)=7/20,P(B)=3/5,P(A∩B)=21/100 ,P(A∪B)=?

icang [17]

$P(A U B) = P(A) +P(B) - P(AB) \\ \\ = \frac{7}{20} +\frac{3}{5} - \frac{21}{100} \\ \\ = \frac{35}{100} +\frac{60}{100} - \frac{21}{100} \\ \\ =\frac{74}{100} \\ \\ =\frac{37}{50}$

balu736 [363]

Answer:

French test

Step-by-step explanation:

We first calculate the scores as percentages:

#Spanish test:

$=\frac{score}{total}\times 100\%\\\\\\=\frac{27}{32}\times 100\%\\\\=84.38\%$

#For the French test, her percentage is:

$=\frac{score}{total}\times 100\%\\\\=\frac{19}{21}\times 100\%\\\\=90.48\%$

Since, 90.48$>84.38%, Claire did better in the French test.

The distance an object travels is determined by how fast it goes and for how long it moves.If an object speed remains constant,t

stepladder [879]

Answer:

250 miles

Step-by-step explanation:

Your formula is d=r(t)

d=distance r=speed t=time

In this equation it is asking you how far will you travel if your speed is 50 miles per hour, and the time is 5 hours.

So, using the equation above insert the known numbers and it should look like this: d=50(5) ( distance is unknown / speed is 50 / time is 5 )

Now you can find the distance. All you do is multiply 50 times 5 which equals 250.

So the correct answer is C. 250 miles
