Assume that the sales of a computer retail store are approximated by a linear function. Sales were $990,000 in 1983 and $2,830,0

00 in 1988. Let x=0 represent 1983. Find the equation given yearly sales. Estimate sales in 1991.

It can't be linear. it has to be an exponential growth soo the equation would be 2,830,000(990,000/12)^ 8

1) check if they given ordered pairs are solutions to the equation or not.
ziro4ka [17]
Answer: a) Yes
b) No


Explanation: Substitute the values of X and Y from the given points into the equation. I’ll use a) as an example:
Given point: (1,-3)
Equation: 4x-2y=10
Value of X: 1
Value of Y: -3
Substitute X and Y: 4(1)-2(-3)=10
4-(-6)=10
4+6=10 ✔︎

Therefore, the given ordered pair is a proper solution to the equation 4x-2y=10.

*You can use the same method for question b).*

20 POINTS AND WILL GIVE BRAINLIEST IF MORE THAN ONE ANSWER!
pickupchik [31]

Answer:

Step-by-step explanation:

or

Step-by-step explanation:

has:

1) amplitude=|a|

2) phase shift=b

3) period=2pi/c

d) vertical shift=d

--------------------------------------------------

You are given the amplitude is 2. This means a could either be 2 or -2.

You are given phase shift is -1/8. This means b is -1/8.

You are given the period is pi. So we need to solve pi=2pi/c.

pi=2pi/c

Dividing both sides by pi gives:

1=2/c

Multiply both sides by c gives:

c=2

The vertical shift is -2 so d=-2.

The equation could either be:

y=2cos(2(x-(-1/8)))-2

or

y=-2cos(2(x-(-1/8)))-2

Simplifying a little gives:

y=2cos(2x+1/4)-2

y=-2cos(2x+1/4)-2

Troyanec [42]

Answer:

-4x^2-10x+6

Step-by-step explanation:

I am going to assume the (Something)x2 means (Something)x^2. Then, the expression is 2x^2-6x^2\\+4x-6x+9-3=-4x^2-10x+6
