Answer:

f(x) = -2x + 11

Step-by-step explanation:

okay so if f(-2) = 15 and f(1) = 9

i used desmos to picture it and i got f(x) = -2x + 11

because f(-2) = -2(-2) + 11 = 4 + 11 = 15 so f(-2) = 15

and f(1) = -2(1) + 11 = -2 + 11 = 9 so f(1) = 9

What is the slope of the line passing through the points (-4, 4) and (5,5)?

hram777 [196]

Answer:

Slope = 1/9

Step-by-step explanation:

Use the formula for the slope of a line given two points. I've attached a photo to remind you what the formula is.

m is the slope of the line.

(x1, y1) = (-4, 4) and (x2, y2) = (5, 5)

So plug in the numbers into the formula, which yields:

m = $\frac{5-4}{5-(-4)}$

m = $\frac{1}{9}$

In Exercise,find the balance in the account after 10 years.

Vesnalui [34]

Answer: $ 3462.03

Step-by-step explanation:

The exponential equation for growth (compounded continuously) is given by :-

$A=Pe^{rt}$

, where P= Present value

r= growth rate ( in decimal)

t= time

As per given , we have

P=$1900, r = 6% =0.06 and t= 10

Substitute all the values in the above equation , we get

$A=1900e^{0.06(10)}$

$A=1900e^{0.6}$

$A=1900(1.8221188)=3462.02572\approx3462.03$ [To the nearest cent]

Hence, the balance in the account after 10 years = $ 3462.03
