Answer:

$y = \frac{1}{2}x$

Step-by-step explanation:

First plot (3,1). Then use the slope to create the second point. Go up 1, right 2.

Next draw a line connecting the points. The line touches the y-axis at 0.

$y = mx + b$ is the form you use.

You have to make 1000 buttons.the diameter of the button is 9cm but you have to find it’s area.its $15/m squared and you have to

Semmy [17]

Answer:

$95.38

Step-by-step explanation:

step 1

Find the area of one button

The area is equal to

$A=\pi r^{2}$

we have

$r=9/2=4.5\ cm$ ---> the radius is half the diameter

Convert to meters

$r=4.5\ cm=4.5/100=0.045\ m$

assume

$\pi =3.14$

substitute

$A=(3.14)(0.045)^{2}\\A=0.0063585\ m^2$

step 2

Find the area of 1,00 buttons

Multiply by 1,000

$A=0.0063585(1,000)=6.3585\ m^2$

step 3

Find the cost

Multiply $15 per square meter by the total area of 1,000 buttons

$(15)6.3585=\$95.38$

what is perpendicular to y= 3x -9 and passes through the point (3,1)

GREYUIT [131]

$(3,1) , \ \ y= 3x -9 \\ \\ The \ slope \ is :m _{1} =3 \\ \\ If \ m_{1} \ and \ m _{2} \ are \ the \ gradients \ of \ two \ perpendicular \\ \\ lines \ we \ have \ m _{1} \cdot m _{2} = -1 \\ \\3\cdot m_{2}=-1 \ \ /:3\\ \\ m_{2}=-\frac{1}{3}$

$\Now \ your \ equation \ of \ line \ passing \ through \ (3,1) would \ be: \\ \\ y=m_{2}x+b \\ \\1=-\frac{1}{ 3} \cdot3 + b$

$1=-1+b\\ \\ b=1+1\\ \\b=2 \\ \\ y =- \frac{1}{3}x+2$

zhannawk [14.2K]

Answer:

Let total students who prefer lemonade is 2a and who prefer ice tea is a.

Students in 6th grade=39

2a+a=39

3a=39

a=39/3

a=13

students who prefer lemonate is 13

and those who prefer ice tea is 2a=26
