Answer:

• x = 9

• y = 6√2

Step-by-step explanation:

The right triangles are all similar, so the ratios of hypotenuse to short side are the same:

27/x = x/3

x^2 = 81 . . . . . multiply by 3x

x = 9 . . . . . . . . take the square root

Then y can be found from the Pythagorean theorem:

x^2 = y^2 + 3^2

81 - 9 = y^2 = 72 . . . . . subtract 9

y = √72 = 6√2 . . . . . . .take the square root

The values of x and y are 9 and 6√2, respectively.

A worker on the production line is paid a base salary of $230.00 per week plus $0.78 for each unit produced. Write an equation

iogann1982 [59]

(a)

We are given

A worker on the production line is paid a base salary of $230.00 per week

so, base salary =230

Let's assume number pencils produced as x

plus $0.78 for each unit produced

now, we can find equation for earnings

$E(x)=230+0.78x$

now, we are given

her earnings of $446.84 for a week when she produced x units

so, we can set E(x)=446.84

and then we can solve for x

$446.84=230+0.78x$

$230\cdot \:100+0.78x\cdot \:100=446.84\cdot \:100$

$23000+78x=44684$

$23000+78x-23000=44684-23000$

$78x=21684$

$\frac{78x}{78}=\frac{21684}{78}$

$x=278$

so, number of pencils = 278........Answer

(b)

If the worker had produced twice that number of units

so, number of pencils =2*278=556

now, we can find earnings

$E(x)=230+0.78x$

now, we can plug x=556

$E(556)=230+0.78*556$

$E(556)=663.68$ .................Answer

(2, 7) and (-4,1)<br> In point slope form

GREYUIT [131]

Answer:

First you need to find the slope with this equation.

<h3> $m=\frac{y2-y1}{x2-x1}$ m=slope</h3><h3> $m=\frac{1-7}{-4-2}$ </h3><h3> $m=\frac{-6}{-6}$ </h3><h3> $m=1$ </h3>

So the point slope form formula is:

$y=x-2+7\\y=x+5$ This is the point slope form.I hope this help.
