Write the rule for the linear function. Remember a function rule is written using f(x)

Marina CMI [18]

Answer:

The rule for the linear function will be:

$f(x) = -2x+5$

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points from the table to determine the slope

(1, 3)

(2, 1)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(1,\:3\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)$

$m=\frac{1-3}{2-1}$

$m=-2$

Using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (1, 3)

$y-y_1=m\left(x-x_1\right)$

$y - 3 = -2 (x-1)$

$y-3 = -2x+2$

adding 3 to both sides

$y-3+3 = -2x+2+3$

$y = -2x+5$

$f(x) = -2x+5$

Therefore, the rule for the linear function will be:

$f(x) = -2x+5$

In the diagram PQR and T are points on the circumference of a circle PTS and QRS are straight lines.PR is a diameter , QSP=28° a

Digiron [165]

Step-by-step explanation:

a)<PTR=90°(angles in a semicircle)

<RPT=50°

<PRT + <PTR + <RPT=180°(angles in a triangle)

<PRT=180-(90+50)

<PRT=40°

b)From ∆QTS

<TQS = <RTP =50°

<QTS=180-(50+28)

<QTS=102°

c)<QTR=180-(90+50)

<QTR=40°

What is the area of ∆DEF shown in the figure? Show your work.

Romashka [77]

Congratulations on posting the figure.

Area is (1/2) * base * height, here

Area = (1/2) (21) (18) = 9*21 = 189

Answer: 189 sq yds
