Answer:

im guessing you're trying to find where the lines will meet at, so the lines will meet at (1,-1)

Step-by-step explanation:

sadly it doesnt allow me to add in a photo but ill tell you a good enough explanation of what to draw, for y=3x+2 your line starts at 2 on the y axis and goes down (-3/1)

for y=3x-4 your line starts at -4 and go up by 3/1

Misha Larkins [42]

Answer:

x = 7

Step-by-step explanation:

Let

x = the unknown number

double it :

add 11:

2x + 11

I get 25:

The equation is

2x + 11 = 25

2x = 25 - 12

2x = 14

Divide both sides by 2

x = 14/2

x = 7

What is x^2 -11x+19=-5 as standard form?

IrinaVladis [17]

Answer:

<em>Standard Form; x^2 - 11x + 24 = 0</em>

Step-by-step explanation:

Simplify rewrite such that the quadratic equation has 0 isolated on the right or left side, most commonly right side;

x^2 - 11x + 19 = - 5 ⇒ Add 5 on either side of equation,

<em>Standard Form; x^2 - 11x + 24 = 0</em>

Christine Wong has asked Dave and Mike to help her move into a new apartment on Sunday morning. She has asked them both, in case

lozanna [386]

Answer:

0.3339 = 33.39% probability that both Dave and Mike will show up

Step-by-step explanation:

Probability of independent events:

If A and B are independent events, the probability of both happening at the same time is given by:

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

In this question:

Event A: Dave shows up.

Event B: Mike shows up.

Christine knows that there is a 47% chance that Dave will not show up and a 37% chance that Mike will not show up.

This means that $P(A) = 1 - 0.47 = 0.53, P(B) = 1 - 0.37 = 0.63$ .

a. What is the probability that both Dave and Mike will show up

$P(A \cap B) = P(A)P(B) = 0.53*0.63 = 0.3339$

0.3339 = 33.39% probability that both Dave and Mike will show up
