What is the slope of the line passing through the points (–1, 3) and (4, –7)?

Nataliya [291]

Slope=rise/run
slope=(y2-y1)/(x2-x1) if you have the points
(x1,y1) and (x2,y2)

we have the points (-1,3) and (4,-7)
x1=-1
y1=3
x2=4
y2=-7

slope=(-7-3)/(4-(-1))=-10/5=-2

answer is D

Thankyou for all the help

Travka [436]

Answer:

1. x + y = 180

2. x = 50 y= 130

Step-by-step explanation:

They're parallel.

We can label the unamed angle z.

So z = y

and 50 = x

There's 360 degrees in a circle, so x + y= 180 because it's half 360 and half a circle.

x=50

so 50 + 50 = 100.

360 - 100 = 260

so 260 ÷ 2 = 130

y = 130 because y and z are equal so they're the same number

Melanie invested $5,500 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawa

Phantasy [73]

Answer:

$A=\$11,748.76$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$t=11\ years\\ P=\$5,500\\ r=6.9\%=6.9/100=0.069$

substitute in the formula above

$A=5,500(e)^{0.069*11}$

$A=5,500(e)^{0.759}$

$A=\$11,748.76$
