Answer:  56 mph

Step-by-step explanation:

48 miles x 2 hours = 96 miles

60 miles x 4 hours =  240 miles

240 + 96 = 360 total miles

360 / 6 (hours) = 56 mph

3) Expresa mediante una fórmula la función que a un número entero x le hace corresponder el doble del número siguiente a x. Haz
jonny [76]

Answer: The function is: f(x) = 2*(x +1)

Step-by-step explanation:

This can be translated to:

"write an equation of a function where a whole number x corresponds to the next number to x"

the next whole number to x is x+1., and we want the double of that.

Then we have that our function is:

f(x) = 2*(x +1)

Now we can do a little table of it:

f(0) = 2*(0 + 1) = 2

f(1) = 2*(1 + 1) = 4

f(2) = 2*(2+ 1) = 6

What is the equation of the circle with center (-6,7) that passes through the point (4,-2). A. (x+6)^2+(y-7)^2=181 B. (x-6)^2+(y
pychu [463]
The equation of a cricle passing through (h,h) and with radius r is
(x-h)^2+(y-k)^2=r^2
so

cente ris (-6,7) and passing through (4,-2)
(x-(-6))^2+(y-7)^2=r^2
(x+6)^2+(y-7)^2=r^2
subsitute (4,-2) to find r^2

(4+6)^2+(-2-7)^2=r^2
(10)^2+(-9)^2=r^2
100+81=r^2
181=r^2

so it is

(x+6)^2+(y-7)^2=181

Solve the system of linear equations by elimination.<br><br> −2x−5y=9<br> 3x+11y=4
goldenfox [79]

Answer:

x=-17, y=5. (-17, 5).

Step-by-step explanation:

-2x-5y=9

3x+11y=4

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

3(-2x-5y)=3(9)

2(3x+11y)=2(4)

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

-6x-15y=27

6x+22y=8

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

7y=35

y=35/7

y=5

3x+11(5)=4

3x+55=4

3x=4-55

3x=-51

x=-51/3

x=-17

Sixteen scholars have volunteered to stay after school to help set up for the school musical. The musical director plans to orde
lapo4ka [179]
The director would have to pay $40.47.

If each scholar eats one slice of pizza, then there would be two pizza pies because 8 slices plus another 8 slices in 16

8+8=16

If all of them eat another .5 slice, adding up the halves would equal 8

.5 x 16 = 8

In total, the director would have to buy three pizzas which equals up to our total of $40.47
