Answer:

Vertex is at (4, 2)

Step-by-step explanation:

to find the 'x' value of the vertex, use 'x = -b/2a'

in this problem, a = 1, b = -8, c = 18

x = -(-8)/2(1)

x = 8/2

x = 4

plug 2 in for 'x' in equation and solve for 'y':

y = 4² - 8(4) + 18

y = 16 - 32 + 18

y = -16 + 18

y = 2

Vertex is at (4, 2)

Two cars travel along a highway at the same speed.

Mazyrski [523]

Answer:

30 mins

Step-by-step explanation:

<em>speed = distance/ time </em>

speed of car A

= 20/ 12 km/ min

= 5/ 3 km/ min

also, speed of car A = speed of car B

speed of car B = 5/ 3 km/ min = 50km / time taken (in mins)

$\frac{5}{3} = \frac{50}{t}$

$5t = 150$

$t = 30$

=> t = 30 mins

In March, there will be two conferences: one for math and one for history. So far, 7 people have signed up for the math conferen

otez555 [7]

Answer:

After 4 days, the number of people attending both conferences be the same.

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$f(x) = 7+2x$

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$g(x) =11+x$

Both conference will have same number of people when

$f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4$

Thus, after 4 days, the number of people attending both conferences be the same.

WITCHER [35]

Answer:

The answer to your question is 7 times

Step-by-step explanation:

Data

Percent of accuracy = 35%

Times she is at bat = 20

Times she hit the ball = ?

Process

1.- Use proportions to solve this problem

20 times will be the 100% because is the total number of times she is at bat.

20 times ------------------ 100%

x ------------------ 35%

x = (35 x 20) / 100

x = 700 / 100

x = 7

2.- Conclusion

From 20 times she is at bat, she will hit the ball 7 times.
