Evaluate (-A) 2 for A = 5, B = -4, and C = 2.

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:

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:

Answer:

x = 27

Step-by-step explanation:

solving similarities using equations:

→[tex]\frac{CD}{QD} = \frac{RD}{BD}[/tex]

→ [tex]\frac{x}{39} = \frac{18+x}{26+39}[/tex]

→ [tex]\frac{x}{39} = \frac{18+x}{65}[/tex]

→ 65(x) = 39(18+x)

→ 65x = 702 + 39x

→ 65x - 39x = 702

→ 26x = 702

→ x = 27

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.

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

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.

Hope this helps, just do the same for the other problems like this one.

Answer:

243 and 394

Step-by-step explanation:

f(x) is the exponential as its values increase by 3 every hour, then

when x = 5

f(5 ) = 81 × 3 = 243

---------------------------

g(x) is linear as there is a common difference between consecutive values of + 3 , then

when x = 5

g(x) = 391 + 3 = 394

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.

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).
