Which choice shows +=7

Answer:

$y=-x+7$

The graph in the attached figure

Step-by-step explanation:

we have

$x+y=7$

This is the equation of the line in standard form

Convert to slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

Isolate the variable y

subtract x both sides

$x+y-x=-x+7$

simplify

$y=-x+7$

The y-intercept is the point (0,7)

Find the x-intercept

For y=0

$0=-x+7\\x=7$

The x-intercept is the point (7,0)

Plot the intercepts and join them to graph the line

see the attached figure

Given the following rectangle and circle, at what approximate value of x are the two areas equal? x ≈ 5.8 x ≈ 3.4 The curves do

SIZIF [17.4K]

The approximate value of x will be approximately equal to 3.4

<h3>Area of triangle and circle</h3>

The formula for calculating area of rectangle is expressed as:

A = lw

l is the length
w is the width

Ar = (3x-1)(x+2)

Ar = 3x^2+6x-x-2

Ar = 3x^2 + 5x - 2

For the circle

Ac = πr²

Ac = 3.14(x-3)²

Ac = 3.14(x²-6x+9)

Ac = 3.14x² - 18.84x + 28.26

If the area are equal;

3x² + 5x - 2 = 3.14x² - 18.84x + 28.26

3.14x² - 3x² - 5x - 18.84x + 30.26 = 0
0.14x²-23.84x+30.26 = 0

On factorizing the equation, the approximate value of x will be approximately equal to 3.4
