Answer:

Option C

Step-by-step explanation:

Let's look at the graphs one by one:

The graph has rising and falling exponential functions, therefore, it will not fit the pattern. The graph has a negative exponent function.

Let's skip graph C.

Graph B looks like the correct answer, however, the graph has a negative exponent and then rises up again.

Graph D is out of question as it has uneven exponents.

Graph C has an even function.

Write the equation for the line that passes through (2, -4) and is

Kryger [21]

Answer: y= x-2

Step-by-step explanation:

Perpendicularity entails the slope of line a is -1 divided by the slope of line b

m1= (-1/m2)

From y=Mx +c

We compare with x-4y=7

y=(1/4)x-7/4

Meaning m2= 1/4

m1= -1/(1/4)= -1*4= -4

((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1

x1= 2, y1= -4

((y-(-4))/(x-2))= -4

((y+4)/(x-2))= -4

Cross multiply

y+4= -4(x-2)

y= x-2

At a competition with 6 runners, 2 medals are awarded for first and second

insens350 [35]

Answer:

30 ways

Step-by-step explanation:

The first medal can be awarded in 6 different ways since any of the runners could have it. Once the first medal is awarded, the second medal can only be given to any of the 5 runners available.

So there are 6x5=30 different ways to award the medals

PLS HELP ME THIS IS DUE IN A FEW HOURS(i need a graph too pls)

Answer:

Yes, the total cost of Lacey lesson is a split function of hours scheduled

Step-by-step explanation:

The amount Lacey pays for each hour of golf = $15

The amount Lacey pays for equipment rental = $10

The amount Lacy pays for equipment rental for a 3 hours long lesson = $5

Therefore, we have

Let C represent the total cost of Lacey lesson and let t represent the number of hours, we have;

C = $10 + t × $15 for 0 ≤ t ≤ 3

C = $5 + t × $15 for t > 3

Therefore, the total cost of Lacey lesson is a split function of hours scheduled

Directions: Follow the instructions for the following inequalities.

dmitriy555 [2]

Answer:

1. 5050 < 8820

2. 15 > 6

3. -20 , -18

4. -1 < 1

Step-by-step explanation:

1. 4 < 7

multiply both sides by 7: 4 x 7 < 7 x 7 = 28 < 49

then multiply both sides by 6: 28 x 6 < 49 x 6 = 168 < 294

then multiply both sides by 3: 168 x 3 < 294 x 3 = 505 < 882

then multiply both sides by 10: 505 x 10 < 882 x 10 = 5050 < 8820

Did not affect the inequality sign

2. 11 > 2

Add 5 to both sides: 11 + 5 > 2 + 5 = 16 > 7

then add 3 to both sides: 16 + 3 > 7 + 3 = 19 > 10

then add -4 to both sides: 19 - 4 > 10 - 4 = 15 > 6

Did not affect the inequality sign

3. -4 < -2

Subtract 6 from both sides: - 4 - 6 < - 2 - 6 = -10 < -8

then subtract 8 from both sides: -10 - 8 < -8 - 8 = -18 < -16

then subtract 2 from both sides: -18 - 2 < -16 - 2 = -20 , -18

Did not affect the inequality sign

4. -8 < 8

Divide both sides by -4: -8 ÷ -4 < 8 ÷ -4 = 2 > -2

then divide both sides by -2: 2 ÷ -2 > -2 ÷ -2 = -1 < 1

Did affect the inequality sign throughout the operations, as when dividing by a negative number, flip the sign

Adding or subtracting the same quantity from both sides of an inequality leaves the inequality symbol unchanged.
Multiplying or dividing both sides by a positive number leaves the inequality symbol unchanged.
Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to > (and vice versa)
