Answer:

B). (1,8)

Step-by-step explanation:

You can build graphical using both equation

  1. y=x+7
  2. y=-2x+10

1. When y=0, so x=-7 and when x=0, so y=7

2. When y=0, so x=5 and when x=0, so y=10  

So in the image graphic 1 is red and graphic 2 is blue and you can see they cross at (1,8)

To check

1=2 so, x+7=-2x+10 \\ 3x=3 \\ x=1

Replacing:

1. y=1+7=8 and 2. y= -2*1 +10=8

So (1,8)

Answer:

LQ = 5

Median = 6

Step-by-step explanation:

\frac{n+1}{2} gives us 5.5, so we do the average of position 5 and 6. This gives us 6, so the median is 6.

Now we find the median of the bottom half of the numbers, which is 5, so the LQ is 5.

Now we find the median of the upper half of the numbers, which is 7, so the UQ is 7.

Answer:

3.2 x 10^13

Step-by-step explanation:

(8x10^4)(4x10^8)

reorder the terms using the commutative property

(8x4)x(10^4x10^8)

multiply

32x (10^4 x 10^8)

= 32 x 10^4+8

= 32 x 10^12

now convert to scientific notation

=3.2 x 10^13

The value of y is directly proportional to the value of x. Given y = 12 when x = 36.
Ahat [919]

Answer:

y = 20

Step-by-step explanation:

The problem states that y = 12 when x = 36. 36/12 is 3. This means that y is a third of what x is. This would mean that if x = 60, y would be a third of 60 which is 20 since 60/3 is 20.

During a baseball game, a player’s ball hit into the outfield is modeled by the equation h = –16t2 + 65t. A bird flying across t
natka813 [3]
When two graphs intersect, it means something in real-life:

The baseball's flight path and the bird's flight path intersect. 

Therefore, the baseball hits the bird. (Technically, we can see that the baseball would hit the bird twice, but this is not likely.)
