         If          f(x)  =  2x + 4

         then      f(cow)  =  2(cow) + 4

         and      f(1 quart)  =  2(1 quart) + 4

         and      f(3)  =  2(3) + 4

                            =    6   + 4

                            =       10

aniked [119]

Answer:

46,000,000 (46 million)

Step-by-step explanation:

If the number to the right (in this case the hundred thousands place) is 5 or greater then you round up.

If it was lower than 5 you would round down.

As the number in the hundred thousands place is 6, this means we can round up.

2 If m please help me
Nadusha1986 [10]

Answer:

x = 18

m∠HCB = 36

Step-by-step explanation:

The measure of angle FBC is 8x and the measure of angle HCB is 2x. If you add the measures of both angles it will equal to 180 degrees. This can be represented in an equation:

8x + 2x = 180

10x = 180

Divide both sides of the equation by 10 to isolate the x:

10x/10 = 180/10

x = 18

Now that we know the value of x, we can find the measure of angle HCB:

2x

2(18)

36

The measure of angle HCB is 36.

I hope this helps :)
