What is the slope of the line that contains the point -6,-7 and -6,2

2 answers:

8 0

We know that coordinates are labeled (x,y)
The formula to find slope is (Y2-Y1)/(X2-X1)
So (2- (-7))/(-6-(-6) undefined because the denominator is zero. The line looks like a vertical line at x=-6

Answer:

Slope is undefined.

Step-by-step explanation:

slope is defined as the steepness of a line.It is also called gradient.

It is denoted by m.

It is ratio of change in y to change in x.

m=Δy/Δx= $y_{2} -y_{1} /x_{2} -x_{1}$

From question statement, we observe that

$x_{1} =-6,y_{1} =-7$

$x_{2} =-6,y_{2} =2$

putting above values in formula to find slope,we get

m=2-(-7)/-6-(-6)

m=2+7/-6+6

m=5/0= undefined.

The slope of vertical line is undefined.

Answer:

range=14

mode=9

median =9

mean =12

Step-by-step explanation:

range is B-S=20-6

mode is most common

median put in order find middle value 6,9,9,9,9,11,13,16,18,20

mean is add all divide by how many 9+9+9+9+6+11+13+16=120/10

Jordan has $275.00 in his bank account the bank will pay jordan 4% interest per year on the value of hois account if jordan does

Sunny_sXe [5.5K]

Answer:

$\$286.00$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=1\ years\\ P=\$275.00\\r=4\%=4/100=0.04$

substitute in the formula above

$A=275.00(1+0.04*1)$

$A=275.00(1.04)$

$A=\$286.00$

Six machines, each working at the same constant rate, together can complete a certain job in 12 days. How many additional machin

aev [14]

Answer:

The answer to your question is letter C

Step-by-step explanation:

This is a problem with the inverse rule of three because we expect that more machines can complete the same work in fewer days.

6 machines ------------------ 12 days

x machines ------------------- 8 days

x machines = $\frac{(8 days)(6 machines)}{12 days}$

$x machines = \frac{48 machines}{12}$

x = 4 machines

The function V(t)= 1,000(1.06)^2t models the value of an investment after t years.

RideAnS [48]

Answer:

It's 1,000

Step-by-step explanation:

exponential form is f(x)= a × b^2

(a=initial amount)

(b=growth rate)

you would replace a for 1000 and b for .06 (+1)

v(t)=1000(1.06)^2t

therefore the initial amount is 1000

if this didnt help sorry lol
