Table shows ordered pair that satisfys the function y=3x/2

Mathematics
1 answer:
BabaBlast [244]3 years ago

Answer:

x: 0,   1,  2,    3,  4,    5

y: 0, 1.5, 3, 4.5, 6, 7.5

Step-by-step explanation:

To create a table that satisfies a function, you need to first choose some x values. Some common x values are 0, 1, 2, 3, 4, 5 or -2. -1, 0, 1, 2, but it doesn't matter which numbers you choose.

Then, plug the x values in to the function to get a table of y-values.

I chose the x-values as 0, 1, 2, 3, 4, 5 but these numbers could be anything. To find the y, I plugged each x into the function.

y = 3 * ( 0 ) / 2 = 0 / 2 = 0

y = 3 * ( 1 ) / 2 = 3 / 2 = 1.5

y = 3 * ( 2 ) / 2 = 6 / 2 = 3

y = 3 * ( 3 ) / 2 = 9 / 2 = 4.5

y = 3 * ( 4 ) / 2 = 12 / 2 = 6

y = 3 * ( 5 ) / 2 = 15 / 2 = 7.5

In ΔXYZ, ∠Y=90° and ∠X=73°. ∠ZWY=80° and XW=80. Find the length of ZY to the nearest 100th.
lawyer [7]

Answer:

Solution given:

Y=90°

∠X=73°.

∠ZWY=80°

and XW=80.

ZY=?

We know that

In right angled triangle ∆ XYZ

Tan 73=\frac{p}{h}

3.27=\frac{yz}{xy}

3.27×[xy]=yz

xw+wy=\frac{yz}{3.27}

wy=\frac{yz}{3.27}-80...........(1)

again

In right angled triangle WYZ

Tan 80=\frac{yz}{wy}

5.67×wy=yz

wy=\frac{yz}{5.67}

yz=5.67×wy............................................(2)

E<u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>n</u><u>g</u><u> </u><u>equation</u><u> </u><u>1</u><u>&</u><u>2</u>

\frac{yz}{5.67}=\frac{yz}{3.27}-80

\frac{yz}{3.27}-\frac{yz}{5.67}=80

5.67yz-3.27yz=80*5.67*3.27

2.4yz =1483.272

yz=\frac{1483.272}{2.4}

yz=618.03

:.y=618.03unit.<u>the length of ZY to the nearest 100</u><u>th</u><u> </u><u>is</u><u> </u><u>6</u><u>1</u><u>8</u><u>.</u>

How many solutions does the system have?
marishachu [46]

Answer:

{x,y} = {-2,2}

Step-by-step explanation:

Solve equation [2] for the variable  y  

 

  7y = 7x + 28

  y = x + 4

Plug this in for variable  y  in equation [1]

-8x + 4•(x +4) = 24

-4x = 8

Solve equation [1] for the variable  x  

4x = - 8  

x = - 2

By now we know this much :

   x = -2

   y = x+4

Use the  x  value to solve for  y  

   y = (-2)+4 = 2

Solution :

{x,y} = {-2,2}

and this intersects at only one point so your answer is A
