The table shows a linear function. <br><br> Which equation represents the function.
mote1985 [20]

Answer:

\large\boxed{f(x)=\dfrac{3}{2}x-1}

Step-by-step explanation:

\text{The slope-intercept formula:}\\\\y=mx+b\\\\m\ -\ slope\\b\ -\ y-intercept\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{From the table we hve two points (0, -1) and (2, 2). Substitute:}\\\\m=\dfrac{2-(-1)}{2-0}=\dfrac{3}{2}

\text{Therefore the equation is}\ f(x)=\dfrac{3}{2}x-1\\\\\text{Check for  the point (4, 5):}\\\\f(4)=\dfrac{3}{2}(4)-1=(3)(2)-1=6-1=5\qquad\ CORRECT

Write the equation of a line in slope-intercept form parallel to the line y = -2x + 7 and contains (-1, 3).
JulsSmile [24]

Answer:

The answer is

<h2>y = - 2x + 1</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y = - 2x + 7

Comparing with the general equation above

Slope = - 2

Since the lines are parallel their slope are also the same

Slope of parallel line = - 2

The equation of the line using point (-1, 3) and slope - 2 is

y - 3  =  - 2(x + 1) \\ y - 3 =  - 2x - 2 \\ y =  - 2x - 2 + 3

We have the final answer as

y =  - 2x + 1 \\

Hope this helps you

Look at the expression you entered in the table in part C. Write them backward as a sum, starting with the amount from month 12.
atroni [7]

Answer: =

Write the expressions backward from month 12 to month 1 to get this series:

50 + 50(1.003) + 50(1.003)2 + ... + 50(1.003)11

Convert the series to sigma notation, and find the sum of the 12 terms in the series:

11

S12 50(1.003)

ko

50(1 - 1.00312)

1 - 1.003

610
