Assume that the sales of a computer retail store are approximated by a linear function. Sales were $990,000 in 1983 and $2,830,000 in 1988. Let x=0 represent 1983. Find the equation given yearly sales. Estimate sales in 1991.

Answers

Answer 1

Answer:

To find the equation for the linear function representing the sales, we need to find the slope (m) and the y-intercept (b).

The slope, m, can be calculated using the formula: m $= (y2 - y1) / (x2 - x1),$ where (x1, y1) and (x2, y2) represent points on the line. Using the given data, $(1983, $990,000)$ and $(1988, $2,830,000),$ we have: m = $(2,830,000 - 990,000) / (1988 - 1983) = 568,000$ Substituting one of the points, say (1983, $990,000), into the equation y = mx + b, we can solve for b: $990,000 = 568,000 * 0 + b b = 990,000$

Therefore, the equation representing the sales is: y $= 568,000x + 990,000$ . To estimate the sales in 1991, we substitute x = 8 (since 1991 corresponds to x = 8) into the equation: y $= 568,000 * 8 + 990,000 y = 4,544,000 + 990,000 y ≈ $5,534,000.$ Therefore, the estimated sales for 1991 would be approximately $5,534,000.

What 2 numbers multiplied equal -48 and 2 numbers added equals -2

Answers

-8 and 6.

work: -8 x 6 = -48
-8 + 6 = -2

Answer:

6 and -8

Step-by-step explanation:

6x-8=-48

6+(-8)=-2

to find these number list what numbers you multiply together to get -48 but if you add them together u get -2

since in multiplication the 48 has a negative sign the one number is negative the other is positive

and since in addition the 2 is negative then the bigger number is also negative

Answers

Write the fraction like this:
$1 (1)/(4)+ 2(1)/(2) = (1\cdot4+1)/(4) + (2\cdot2+1)/(2) = (5)/(4)+ (5)/(2) = (5)/(4) + (5\cdot2)/(2\cdot2)= (5+10)/(4) =\boxed{ (15)/(4) }$

$1(1)/(4)+2(1)/(2)=1(1)/(4)+2(2)/(4)=3(3)/(4)$

What is the correlation coefficient of y=0.48x+75.2

Answers

a correlation coefficient shows how linear a set of data is, so for any points that comply with the given equation, the correlation coefficient will be one, that is, the correlation is completely linear, because the given equation is alinear one, there is a linear correlation of x and y. Indeed, the equation is a line equation in general form.

Solve for x: 2 over 3 (x - 4) = 2x.

Answers

2/3 (x - 4 ) = 2x

Simplify both sides of the equation.

2/3(x−4)=2x

Simplify:

2/3(x−4)=2x

(2/3)(x)+(2/3)(−4)=2x(Distribute)

2/3x+−8/3=2x

Subtract 2x from both sides.

2/3x+−8/3−2x=2x−2x

−4/3x+−8/3=0

Add 8/3 to both sides.

−4/3x+−8/3+8/3=0+8/3

−4/3x=8/3

Multiply both sides by 3/(-4).

(3/−4)*(−4/3x)=(3/−4)*(8/3)

x=−2

The correct answer for the value of for the expression $(2)/(3)(x - 4) = 2x$ is
