Hold your hands out in front of you with your palms facing up. Each of your ten fingers represent a number. Moving from your left thumb to your right thumb, count out the numbers from one to ten. 2 Point the finger you want to multiply by nine down towards your body. For example, if you want to solve (9x3) you will want to hold down your middle finger on your left hand. The middle finger represents the number three because, if you count your fingers from one to ten beginning with your left thumb, your middle finger is the third finger. 3 Solve the problem by counting fingers to the left and right. First count the fingers to the left of your bent finger - in this case there should be two. Next count the fingers to the right of your bent finger - in this case there should be seven. The first digit of the answer is 2 and the second digit is 7. The answer is 27![1]

alexdok [17]

Answer:

Step-by-step explanation:

In this case we know the composition of f and g is

f(g(x))=f(5x-1)=5x-1+2=5x+1

Thus if we change x by 3 we get

f(g(3))=5(3)+1=16

LekaFEV [45]

Answer:

y = 3x + C

y = mx + 5

y = 3x + 5

Step-by-step explanation:

A. The standard form for lines with slope = 3 is

y = 3x + C where C is the y-intercept and can be any number

B. The standard form for lines with y-intercept = 5

y = mx + 5 where m is the slope and can be any number

C. The only line with slope = 3 and y-intercept =5

y = 3x + 5

There is only one line because both m and C are given.

sveticcg [70]

The Dolphins football team gained 16 yards on their first play, then lost 11 yards on the next play. Write an addition expression to represent this situation. Find the sum and explain its meaning.

Answer: On the first play, Dolphin's football team gained 16 yards.

On the 2nd play, Dolphin's football team lost 11 yards.

Therefore, the addition expression to represent this situation is:

16 +(-11)

The sum of this expression is:

16 +(-11) = 16-11 = 5

Therefore, we can interpret it as: Dolphin's football team gained 5 yards over the 2 plays
