Kam can make 72 cookies in 3 hours, Madison can make 128 cookies in 4 hours. How many hours would it take them to make 200 cookies together?

Answer:

1. m = -3 b = 2

2. m = 1/2 b = -1

3. m = -1 b = 79

4. m = 2 b = -2

5. y = -4x + 3

Step-by-step explanation:

1. the equation y=mx + b is used in number 1. m = slope and b = y intercept. so, because -3 is in the m spot, it is the slope, and because 2 is in the b spot, it is the y intercept.

2. apply the same concept as number 1. 1/2 is in the m spot, so it is the slope, and -1 is in the b spot, so it is the y intercept

3. To know the slope of the graph, you do rise/run. meaning, from one point on the graph, count how many times you go down to get to the next points, and then how many times you go over to get to the point. So, the slope of this line is -2/2, which is equal to -1. So, m = -1. To get the y intercept, take a pair of points from the graph (for example, (3,76)) and take the slope, and fill those in to the y = mx + b equation, and then solve for b. so, you get 76 = -1(3) + b. then do -1 times 3 and get -3. add 3 to both sides and you get b = 79.

4. apply the same concept on number 4 as you did number 3. Find rise/run, and you get 2/1, so m = 2. then take a point from the line (like point (0,-2)) and and the slope and fill it in to  y = mx + b. you get -2 = -2(0) + b. so, b = -2.

5. simply fill in the information into the y = mx + b equation. remember, m is the slope, and b is the y intercept. so, you get y = -4x + 3

Answer:

f(x)=9(x+3)^2+2

Step-by-step explanation:

f(x)=9x^2 --> a=9

f(x)=a(x-h)^2+k -->f(x)=9(x-h)^2+k

vertex= (-3,2) --> h=-3 and k=2--> making it f(x)=9(x+3)^2+2

Answer:

Angle 3= 135

Step-by-step explanation:

Angle 3=Angle 1 because they are corresponding angles meaning they are equal and on the same side of the traversal.

Hope this helped and the answer was right in the question

Answer:

Step-by-step explanation:

corresponding angles are congruent, equal to each other.

therefore, ∠1 ≅ ∠3 which is 135°

Answer:

6

Step-by-step explanation:

3x12 = 36

(4+2)    6

simplify

36/6=6

The value is indeed 6 and there shouldn't be a variable because if there is, then there should be a variable in the question.

The simplified form of the expression (3 × 12)/(4 + 2) is 6.

PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.

Given, An expression (3 × 12)/(4 + 2).

Now, 12×3 is 36, and (4 + 2) is 6.

Therefore the simplified form of the expression is,

= 36/6.

Now, we know that 6 times 6 is 36 so, 36 divided by 6 the quotient should be 6.

Therefore,

36/6.

= 6.

So, The value of the expression  (3 × 12)/(4 + 2) is 6.

Answer: 87.50

Step-by-step explanation:

Answer:

$35.7

Step-by-step explanation:

you can convert 15% to a decimal by dividing by 100.

15/100 = .15

if you multiply the decimal by the cost of the shirt you get how much the discount is.

0.15 * $42 = 6.30

so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.

$42 - $6.30 = $35.70 that is the sale price of the shirt.

Answer:

$35.7

Answer:

k = -50

Step-by-step explanation:

3/5k - 5 = 7/10k

3*2 / 5 *2 = 6/10 to get a common denominator

6/10k - 5 = 7/10k subtract 6/10 from 7/10

-5 = 1/10k now eliminate fraction by multiple both sides by reciprocal (10/1)

-5(10) = 1/10(10)k

-50 = k

Answer:

8$ if my math is correct.

Step-by-step explanation:

Kind of a trick question. It is asking how much each bottle costs. You know that there are 18 bottles and have a total cost of $144. You  do not need the 25oz for this equation. Lastly, I divided the total cost by 18 to get the total of 8$ for each bottle
