If a graph of the quadratic equation is given, how do you find the vertex?

Answers

Answer 1

Answer:

Look for the lowest point of the curve

Step-by-step explanation:

The vertex is generally where two or more curves meet, so if you have a standard ax2+bx+c quadratic, it would be the lowest point of the graph.

The image below should point it out.

The next event requires each runner to jump 8 hurdles that are spaced 12. 3 meters apart. If there are 15 meters from the starting line to the first hurdle and 10. 5 meters from the last hurdle to the finish line, how long is the race? Show your work.

Answers

The race is 123.90 meters long.

Since the next event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart, if there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line, to determine how long is the race, the following calculation must be performed:

8 x 12.30 + 15 + 10.5 = X 98.4 + 25.5 = X 123.90 = X

Therefore, the race is 123.90 meters long.

Draw a line labeled 3 times y equals minus 2 x plus 2 by joining the ordered pairs negative 2, 2 and 4, negative 2. What is the solution to the system of equations? a (−2, 2) b (2, 2) c (2, −2) d (−2, −2)

Answers

Answer:

A

Step-by-step explanation:

The problem wants you to solve graphically, but I don't have graph paper with me. To solve graphically, draw a straight line between the ordered pairs it gives and find the intersection. I will also solve algebraically; setting up our equations we get y=x+4 and 3y=-2x+2. By multiplying the first equation by 3, we can solve by elimination, resulting in 0=5x+10. After rearranging we have x=-2 and plugging back into y=x+4 gives y=2. Therefore our final answer is (-2,2) or A.

Jessica and Laura are shopping for new clothes at a store that is going out of business. The different brands of shirts are all the same price, and the same goes for pants. At the store, Jessica purchases 3 shirts and 4 pairs of pants for a total of $90. Laura purchases 4 shirts and 2 pairs of pants for a total of $70.

Answers

Given Jessica and Laura's expenditure on shirts and pants, the equation to solve for the price of each shirts and pants is:

3s + 4p = 90

4s + 2p = 70

Let

Cost of each shirts = s

Cost of each pants = p

Jessica:

3s + 4p = 90 (1)

Laura:

4s + 2p = 70 (2)

Multiply (2) by 2

8s + 4p = 140 (3)

8s + 4p = 140 (3)3s + 4p = 90 (1)

Subtract (1) from (3) to eliminate p

8s - 3s = 140 - 90

5s = 50

s = 50/5

s = $10

substitute s = 10 into (1)

3s + 4p = 90 (1)

3(10) + 4p = 90

30 + 4p = 90

4p = 90 - 30

4p = 60

p = 60/4

p = $15

Therefore, the cost of each shirts is $10 and the cost of each pants is $15

Answer:

x = 5

Step-by-step explanation:

x is to x+5 what x-2 is 70 x+1

x/x+5 = x-2/x+1

x(x+1) = (x-2)(x+5)

x^2+x = x^2+ 5x - 2x - 10

x^2 - x^2 = -x + 5x - 2x - 10
