Darlene is making a quilt that has alternating stripes of regular quilting fabric and sateen fabric. She spends $76 on a total of 16 yards of the two fabrics at a fabric store. Sateen fabric costs $6 per yard and quilting fabric costs $4 per yard. Which system of equations can be used to find the amount x (in yards) of regular quilting fabric and the amount y (in yards) of sateen fabric she purchased?

Answer:

2/5 (or 0.4)

Step-by-step explanation:

There was 50 flips, that's the total. #/50

Head was 20 times, that's the answer we're looking for. 20/50

20/50 Simplified is 2/5 (or 0.4)

I assume "first phase" refers to the first 6.00 seconds of the dash.

Since the sprinter starts from rest and accelerates uniformly, he covers a distance x after time t of

x = 1/2 at²

where a is his acceleration.

The sprinter's velocity v after time t is

v = at

so that if he attains a speed of 14.7 m/s after 6.00 s, he does so with acceleration a such that

14.7 m/s = a (6.00 s)   ⇒   a = 2.45 m/s²

Then in the first 6.00 seconds, the sprinter travels

x = 1/2 (2.45 m/s²) (6.00 s)² = 44.1 m

Answer:

a. yes the money is a function the function is x = days

2^(x-1)

b. no its not it will go up by more and more every day a linear equation would mean it goes up by the same amount each day which it does not

Answer:

  5 units

Step-by-step explanation:

The two points have the same y-coordinate so are on a horizontal line. The distance between them is the difference of their x-coordinates:

  2.5 -(-2.5) = 2.5 +2.5 = 5.0

The distance between the points is 5 units.

Answer:

$ 3937.5

Step-by-step explanation:

First, we convert 1.25% into a decimal.

That would be .0125.

Now we multiply the decimal with the whole number to find our answer.

315000 × .0125 = 3937.5

Therefore, 3937.5 would be the amount of her commission.

Answer:

x = [tex]\frac{1-by}{y-a}[/tex]

Step-by-step explanation:

y = [tex]\frac{ax+1}{x+b}[/tex] ← multiply both sides by (x + b)

y(x + b) = ax + 1 ← distribute parenthesis on left side by y

yx + by = ax + 1 ( subtract ax from both sides )

yx - ax + by = 1 ( subtract by from both sides )

yx - ax = 1 - by ( factor x out of each term on the left side )

x(y - a) = 1 - by ← divide both sides by (y - a)

x = [tex]\frac{1-by}{y-a}[/tex]

Answer:

Step-by-step explanation:

1.  Eliminate fractions by multiplying both sides of this equation by x + b:

                                                                   y(x + b) = ax + 1

2.  Perform the indicated multiplication:   xy + yb = ax + 1

3.  Group together the x-terms                  xy - ax = 1 - yb, or x(y - a) = 1 - yb

                                                                               1 - yb

4.  Divide both sides by (y - a):                    x = ----------------

                                                                                  y - a

Step-by-step explanation:

A. 2 * 10x is equal to 20x

and then 2 * 5 is equal to 10

so the answer is 20x-10

D. 10 *2x is equal to 20x

and then 10 * -1 is equal to -10

so the answer is 20x-10

Answer:

Step-by-step explanation:

fir a 100% is missing 40

divide 28 by 4 and then multiply by 6

Answer:

42 students

40%

72 (end of number line)

Explanation:

How to find the percentage for the 28 students:

100% - 60% = 40%

Knowing that, we now know 28 = 40%. We need to figure out what 10% is equal so we can figure out what 60% is equal.

How to find 10%:

28 ÷ 4 = 7

10% = 7 students

How to find 60% of students:

10 · 6 = 60

7 · 6 = 42

With that information, we can find out the final sum.

40% + 60% = 100%

28 + 42 = 72.

Okay so, to solve these problems what you're gonna want to do is substitute the given x and y values into the equation.

For example, number 7.

11(d-c) + 3(c+d), when c=6, d=9

if d=9, you will substitute the d in the problem to 9.

11(9-c) + 3(c+9)

if c=6 you will substitute c for 6.

11(9-6) + 3(6+9)

You can solve now that you have a simpler problem to work with.

11(9-6) + 3(6+9) first...

11(9-6)  11*9=99   11*-6=-66, so, 11(9-6)= 99-66= 33.

3(6+9) 3*6=18 3*9=27 18+27=45

33+45=78

Your answer for number 7 is 78.

The graph of function f (x) = 2ˣ - 3 is shown in figure.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = 2ˣ - 3

Now, We get;

At x = 1;

⇒ f (x) = 2ˣ - 3

⇒ f (1) = 2 - 3 = - 1

At x = 2;

⇒ f (x) = 2ˣ - 3

⇒ f (2) = 2² - 3 = 1

Hence, The graph is passing through (1, - 1) and (2, 1).

Thus, The graph of function f (x) = 2ˣ - 3 is shown in figure.

The other quantity needed to calculate the average speed is time.

Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.

Average speed = total distance / total time

For example, if the distance travelled is 100km and the total time is 10 hours, average speed is 10 km/hr (100 / 10).
