ANSWER

y=x+5

EXPLANATION

We can observe the following pattern among the x and y-values.

9=4+5

12=7+5

18=13+5

22=17+5

24=19+5

Hence, in general, the function rule is

y=x +5

Answer: Third option.

Step-by-step explanation:

You need to substitute a value of "x" (input value) provided in the table into each function and observe in the value of "y" obtained (output value) matches with the coorresponding output value shown in the table.

For $x=4$

First option:

$y = 5x\\y = 5(4)\\y=20$

Second option:

$y = x + 3\\y = 4 + 3\\y=7$

Third option:

$y = x + 5\\y = 4 + 5\\y=9$

(This one matches with the function table)

Fourth option:

$y = 3x\\y = (3)(4)\\y=12$

Then the answer is: $y = x + 5$

White raven [17]

The answer would be H, because it is rotating 90 degrees which would end up on Quadrant l (+, +).
therefore your answer is H. If you need a little more explaining comment:))

Suppose a family drives at an average rate of 60 mi/h on their way to visit relatives and then an average rate of 40 mi/h on the

hammer [34]

Answer:

Part A) 2 hours

Part B) d/60 hours

Part C) 48 miles/hour

Step-by-step explanation:

Part A) Let "d" be the distance in miles the family traveled to visit their relatives. How many hours did it take to drive there?

we know that

Let

x ----> the time it take on their way to visit relatives in hours

y ---> the time it take on the way back in hours

we know that

The distance of the way to visit is equal to the distance of the way back

The speed multiplied by the time is equal to the distance

60x=40y -----> equation A

y=x+1 -----> equation B

substitute equation B in equation A and solve for x

60x=40(x+1)

60x=40x+40

20x=40

x=2 hours

Find the value of y

y=2+1=3 hours

d=60x

The time it take on their way to visit relatives is 2 hours

The time it take on the way back is 3 hours

Part B) In terms of "d," how many hours did it take to drive there?

we have that

The distance is equal to the speed multiplied by the time

d=60x

Solve for x

x=d/60 hours

Part C) Write and solve an equation to determine the distance the family drove to see their relatives. What was the average rate for the entire trip?

To find the average rate for the whole trip we will need the total distance and the total time

The distance of the way to visit is

d=60x

substitute the value of x

d=60(2)=120 miles

The total distance is

120(2)=240 miles

we know that the total time is

2 + 3 =5 hours

The average rate for the complete trip is

240/5=48 miles/hour

Given u=(5,-2,3) and v=(1,1,2) find ordered triple that represents 3u-2v

kipiarov [429]

Answer:

(13, -8, 5)

Step-by-step explanation:

Given

$u = (5,-2,3)\\and\\v = (1,1,2)$

We have to find 3u-2v

So,

$3u = 3(5,-2,3)\\3u= (15,-6,9)\\\\And\\\\2v= 2(1,1,2)\\2v= (2,2,4)\\\\3u-2v = (15,-6,9) - (2,2,4)\\= (15-2, -6-2 , 9-4)\\= (13, -8, 5)$

The ordered triple that represents 3u-2v is:

(13, -8, 5) ..

What is the discriminant of the quadratic equation 9x2 – X – 8=0?

goldfiish [28.3K]

Answer:

288

Step-by-step explanation:

a = 9

b = -1

c = -8

b^2 * -4 * ( a * c )

Just filing in the numbers given above:

-1^2 * -4 * ( 9 * -8 )

1 * -4 * ( -72)

1 * + 288 = 288
