Answer:

B) y=-3/2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-6-3)/(2-(-4))

m=-9/(2+4)

m=-9/6

simplify

m=-3/2

y-y1=m(x-x1)

y-3=-3/2(x-(-4))

y-3=-3/2(x+4)

y=-3/2x-12/2+3

y=-3/2x-6+3

y=-3/2x-3

Answer:

63%

Step-by-step explanation:

This is a problem of conditional probability.

The two events that are given are:

Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70
Require a tow truck - Let it be event T.

We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)

We are also given the conditional probability, which is P(T | S) = 90% = 0.90

Using the given formula for our case we can modify the formula as:

$P(T|S)=\frac{P(S \cap T)}{P(S)}$

$0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63$

Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out

A house valued at $100000 gains 6%in value. Which expression shows the current value of the house in dollars

Masteriza [31]

Answer:

Current value of house is $106000

Step-by-step explanation:

We are given

A house valued at $100000

gains 6%in value

so,

current value = past house value + gain(%) * (past house value)

past house value =100000

gain(%)=6%

so, we can plug value

Current value is

$=100000+\frac{6}{100}\times 100000$

$=106000$

Which of the following number lines depicts the solution to 4(x+1) > 16 + 7x?

Nataly [62]

9514 1404 393

Answer:

b) x < -4

Step-by-step explanation:

Eliminate parentheses and you have ...

4x +4 > 16 +7x

-12 > 3x . . . . . . . . subtract 4x+16

-4 > x . . . . . . . . divide by 3

The number line will have an <em>open circle</em> at -4 and be shaded to the <em>left</em>. The pictures are a bit fuzzy, but we think choice B has that description.
