there is a line that includes the point (6,-4) and has the slope of -2. What is the equation in slope intercept form

Helga [31]

Answer:

y= -2x+8

Step-by-step explanation:

y-y₁=m(x-x₁)

This is the point slope form equation that can be used to solve this.

Plug in the slope for m and (6,-4) for (x₁,y₁)

y-(-4)=-2(x-6)

Simplify.

y+4= -2x+12

y= -2x+8

aalyn [17]

Answer:

If a person is randomly selected from this group, the probability that they have both high blood pressure and high cholesterol is P=0.25.

Step-by-step explanation:

We can calculate the number of people from the sample that has both high blood pressure (HBP) and high cholesterol (HC) using this identity:

$N(\text{HBP or HC})=N(\text{HBP})+N(\text{HC})-N(\text{HBP and HC})\\\\\\ N(\text{HBP and HC})=N(\text{HBP})+N(\text{HC})-N(\text{HBP or HC})\\\\\\ N(\text{HBP and HC})=15+25-30=10$

We can calculate the probability that a random person has both high blood pressure and high cholesterol as:

$P(\text{HBP and HC})=\dfrac{10}{40}=0.25$

You want to calculate the interest on $2000 at5.8% interest per month after six years?

Here is your formula: I =p*r*t

P is the principal amount which is $2000

R is the rate of interest which is 5.8% per month

T is the time involved whihc is six years

You’re interest is 8352.00
