Answer:

Slope is 1; y-int is (0, 0)

Step-by-step explanation:

Step 1: Identify the slope

The slope is the number attached to the x. Since in this problem there is no number or sign, that means that number in front of it is 1.

y = 1x is same as y = x

So... the slope is 1

Step 2: Identify the y-int

The y-int is the number after the mx, also known as b. In this problem there is no number after, that means that the y-int is 0.

y = mx + b

y = 1x + 0

So... the y-int is (0, 0)

Answer: Slope is 1; y-int is (0, 0)

So first thing is find the number of small boxes. Find 1% of 120, 1.2. Multiply 1.2 by 35, it’s 42.
Next find what the percent that 2/5 is. Divide two by five, it’s .4 or 40%. We already know one percent is 1.2 so multiply 1.2 by 40, 48.
Add this two.
42+48=90.
120-90=30

Small boxes:42
Medium boxes: 48
Large:30
42*6=252
48*10=480
15*30=450
1182 eggs total.

Answer:

x^2 +4x -21

Step-by-step explanation:

Substitute the given expressions and simplify.

f(x) + g(x)

= (x^2 +3x -28) +(x +7)

= x^2 +(3+1)x +(-28 +7)

= x^2 +4x -21

Amy's grandmother gave her 3 identical chocolate chip cookies and 4 identical sugar cookies. In how many different orders can Am

Dmitrij [34]

Answer:

chocolate chip cookie first: 15 ways

chocolate chip cookie last: 15 ways

chocolate chip cookie first and last: 5 ways

Step-by-step explanation:

There is a total of 7 cookies.

Is she eats a chocolate cookie first, she will have 2 chocolate cookies and 4 sugar cookies (6 in total).

So, to find the number of different orders that Amy can eat the remaining cookies, we just need to calculate a combination of 6 choose 2 (that is, the number of ways we can put the 2 chocolate cookies among the 6 cookies) or a combination of 6 choose 4 (same thing, but for the sugar cookies):

C(6,2) = 6! / (2! * 4!) = 6 * 5 / 2 = 15 ways

Is she eats a chocolate cookie last, she will have 2 chocolate cookies and 4 sugar cookies (6 in total), so the problem is solved again with a combination of 6 choose 2:

C(6,2) = 15 ways

Is she eats a chocolate cookie first and last, she will have just 1 chocolate cookie left and 4 sugar cookies (5 in total), so the problem is solved with a combination of 5 choose 1 or a combination of 5 choose 4:

C(5,1) = 5! / (1! * 4!) = 5 ways
