Answer:

y=1/2x+6

Step-by-step explanation:

for the equation you start with finding the rate of change (wich is what y changes by as x 9minths) in creases by 1) and then add the Y-intercept, so it would be Y=1/2x+6

Formula:

Y=△y•x+b(y-int)

To find y intercept find what <em>y </em>is when x is 0, or in this case you know it comes out 6 feet tall, so that is what the Y int. is

Kwame bought a car for $25,000. The value of the car is decreasing at a rate of 6.5% each year. Write a function that represents

sweet-ann [11.9K]

<h3><u>The function that represents the price P of the car after x years is:</u></h3>

$P = 25000(0.935)^x$

<em><u>Solution:</u></em>

<em><u>The decreasing function is given as:</u></em>

$y = a(1 - r)^t$

Where,

y is future value

a is initial value

r is decreasing rate in decimal

t is time period

From given,

a = 25000

$r = 6.5 \% = \frac{6.5}{100} = 0.065$

number of years = x

future value = P

Therefore,

$P = 25000(1 - 0.065)^x\\\\P = 25000(0.935)^x$

Thus the function is found

PLEASE HELP!!

ElenaW [278]

Answer:

-1 and -3

(n+7)(n-8)

Step-by-step explanation:

1. Find the Zeros

$f(x)=x^{2} +4x+3$

$f(x)=\left(x+1\right)\left(x+3\right)$

$x+1=0\\x=-1\\x+3=0\\x=-3$

2. Factoring Trinomials

$f(x)=n^{2} -n-56$

$f(x)=\left(n+7\right)\left(n-8\right)$

$n+7=0\\n=-7\\n-8=0\\n=8$

Hey could anyone explain how to answer this kind of question? Or just solve and show what you did! Thank you!

STALIN [3.7K]

Step-by-step explanation:

9x-3=60°{each angle of equilateral triangle is 60°}
9x=60+3
x=63/9
x=7

so,

9x-3
9×7-3
63-3
60°

hope it helps.

F(x) = 8|x| - 5<br> f(-2) =

Anastaziya [24]

Answer:

f(-2) = 11

Step-by-step explanation:

Hello!

We can evaluate y by plugging in -2 for x in the equation.

<h3>Evaluate</h3>

f(x) = 8|x| - 5
f(-2) = 8|-2| - 5
f(-2) = 8(2) - 5 Remember that absolute value turns the number positive
f(-2) = 16 - 5
f(-2) = 11

The evaluated value is 11.
