I WILL MARK BRAINS!!! 10 POINTS

1 answer:

5 0

A line with undefined slope is a vertical line parallel to the y-axis, passing through all points with the same x-coordinate.

For this reason it's equation is x = c

where c is the value of the x-coordinate the line passes through

For (- 3, 5 ) the x-coordinate is - 3, hence

x = - 3 → is the equation of the line

Identify the reflection of the figure with vertices E(8,4), F(-16,-8), and G(24,-16) across the y-axis.

Dafna1 [17]

Answer:

$\boxed{\text{E$'$(-8, 4), F$'$(16,-8), G$'$(-24,-16)}}$

Step-by-step explanation:

When you reflect a point (x, y) in the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign. Thus,

E (8,4) ⟶ E' (-8,4)

F (-16,-8) ⟶ F' (16,-8)

G (24,-16) ⟶ G' (-24,-16)

$\text{The reflected figure has coordinates } \boxed{\textbf{E$'$(-8, 4), F$'$(16,-8), G$'$(-24,-16)}}$

The figure EFG and its reflection E'F'G' are shown in the diagram below.

The value of y is directly proportional to the value of x. If y=65 when x=5, what is the value of y when x=12?

liraira [26]

Y=65
X=5
X=12
Y=?

65—->5
?——>12

Cross multiply

Y= (65x12) / 5
Y= 780 / 5
Y= 156

To check add the Y value in and remove an X value

65——> ?
156 ——> 12

Cross multiply

X= (12x65) / 156
X= 780 / 156
X= 5

You got the right answer. Hope this helped.

The amount of time that a surveillance camera will run without having to be reset is a random variable having the exponential di

Evgesh-ka [11]

Answer: The required time is 0.743.

Step-by-step explanation:

Since we have given that

$\lambda=0.02$

We need to find the time above which is 68% of the cameras have to be reset.

So, exponential distribution would be

$f(x)=0.02e^{-0.02}$

So, it becomes,

$P(X$

Hence, the required time is 0.743.

a group of 19 students want to see the show at the planetarium. Ticket cost $11 for each student who is a member of the planetar

Illusion [34]

X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247

$-2x = $-38

divide -2 by both sides

x=19, meaning that all of the students are members.
