I NEED HELPPP ON THIS PLZZZ

Mathematics
1 answer:
Anika [276]3 years ago

Answer:

Perimeter of ABCD = <u>56 units</u>

Perimeter of WXYZ = <u>140 units</u>

Step-by-step explanation:

<u>To find the perimeter of ABCD, find the sum of all sides</u>

18 + 18 + 10 + 10 = 56

<u>To find the side lengths of WXYZ, use the equation:</u>   \frac{image}{pre-image}

45/18 = 2.5

<em>You can also cross multiply to find the missing side lengths, but I'll show you this other way...</em>

<u>Multiply the pre-image side lengths by 2.5</u>

18 × 2.5 = 45

10 × 2.5 = 25

<em>45 and 25 of the new side length of WXYZ</em>

<em />

<u>To find the perimeter of  WXYZ, find the sum of all sides.</u>

45 + 45 + 25 + 25 = 140

WX = 45, XY = 25, YZ = 45, ZW = 25

Write an exponential function for graph that passes through the following points (-3,80);(-1,20)
padilas [110]

Answer:

y

=

4

(

1

2

)

x

Explanation:

An exponential function is in the general form

y

=

a

(

b

)

x

We know the points

(

−

1

,

8

)

and

(

1

,

2

)

, so the following are true:

8

=

a

(

b

−

1

)

=

a

b

2

=

a

(

b

1

)

=

a

b

Multiply both sides of the first equation by

b

to find that

8

b

=

a

Plug this into the second equation and solve for

b

:

2

=

(

8

b

)

b

2

=

8

b

2

b

2

=

1

4

b

=

±

1

2

Two equations seem to be possible here. Plug both values of

b

into the either equation to find

a

. I'll use the second equation for simpler algebra.

If

b

=

1

2

:

2

=

a

(

1

2

)

a

=

4

Giving us the equation:

y

=

4

(

1

2

)

x

If

b

=

−

1

2

:

2

=

a

(

−

1

2

)

a

=

−

4

Giving us the equation:

y

=

−

4

(

−

1

2

)

x

However! In an exponential function,

b

>

0

, otherwise many issues arise when trying to graph the function.

The only valid function is

y

=

4

(

1

2

)

x

What is the slope-intercept form of this equation?
quester [9]
8X+6Y=12

Here's how you solve it:

Just isolate y by itself to get y-intercept form.
This is the formula: Y=MX+B

M is the slope or the number next to X in the original problem.

First:
6Y=-8X+12

Next:
divided everything by 6

Y=-4/3+2

I think the answer is A!
