Answer:

x<3.5

Step-by-step explanation:

multiply 2 with 4x and 1 to get 8x + 2 < 3(2x-3). Then multiply 3 by 2x and -3 to get 8x + 2 < 6x- 9. Then subtract -6x on both sides to get 2x + 2< -9. Next subtract 2 from -9 so x is by itself and then you get 2x < 7. Finally divide 2 on each side so you leave x byitself completely. You get x > 3.5

I hope u get it right!

The vertex of the parabola would be located at which coordinates<br> -6,3<br> 6,3<br> 3,-6<br> 3,6

Artemon [7]

<h3><u>Explanation</u></h3>

Given Equation

$y = 4 {(x - 6)}^{2} + 3$

Vertex Form

$y = a {(x - h)}^{2} + k$

where a-term determines how wide/narrow/upward or downward of the graph.

h-term determines the changes of graph for x-axis

k-term determines the changes of graph for y-axis.

The vertex of parabola is at (h,k).

$y = 4 {(x - ( + 6)})^{2} + ( + 3)$

Therefore, h = 6 and k = 3.

<h3><u>Answer</u></h3>

<u> $\large \boxed{(6,3)}$ </u>

P(A and B)=P(A)•P(B) is used when two events are used when two events are

Natali [406]

Answer:

Independent.

Step-by-step explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

$P(A \cap B) = P(A)P(B)$

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.

I need help on how to do these types of problems

aivan3 [116]

#1
Lets x = number of adult tickets
Lets y = number of children tickets

equation 1: 8x + 4y = 5040
equation 2: x + y = 680

solve them by using substitution
x + y = 680
x = 680 - y

substitute x = 680 - y into 8x + 4y = 5040

8(680 - y) + 4y = 5040
5440 - 8y + 4y = 5040
-4y = 5040 - 5440
-4y = -400
y = 100

x = 680 - y
x = 680 - 100
x = 580

Answer:

There were 580 adults and 100 children at the last Miller's home basketball game.

#2
Similar to the #1

Lets x is the number of people riding school bus
Lets y is the number of people riding luxury charter bus

equation 1: x + y = 65
equation 2: 8x + 15y = 611
