Answer:

12.705 miles/hr; Nina is faster

Step-by-step explanation:

If there are 5,280 feet in a mile then:

63360ft*\frac{1mile}{5280 ft} =12 miles

There are 3600 seconds in an hour therefore

3400 s*\frac{1hr}{3600s} =0.944444444 hr

if we divide distance and time we have nina's rate

S=\frac{d}{t} =\frac{12}{0.944} =12.705 miles/hr

Nina's rate is bigger than sophia's 10 miles/hour rate

Write as an ordered pair. 4x+2y=16 and -4y+x=4
Margaret [11]

Answer:

(4,0)

Step-by-step explanation:

4x+2y=16

-4y+x=4

Multiply the first equation by 2

2(4x+2y)=16*2

8x +4y = 32

Add the 2nd equation

8x +4y = 32

x  -4y     =4

--------------------

9x            =36

Divide each side by 9

9x/9 = 36/9

x=4

Now solve for y

-4y +x =4

-4y +4 = 4

Subtract 4 from each side

-4y +4-4=4-4

-4y =0

Divide by -4

-4y/-4 =0/-4

y=0

Find the slope and the y-intercept of the line in the graph.​
Radda [10]

The slope is 2. The y-intercept is 4.

Explanation:

The line constantly goes up to units for every unit that it goes to the right. The y intercept is 4 because it is 4 on the y-axis when x is 0.
