Mathematics
1 answer:
Lisa [10]3 years ago
6 0

Answer:

Step-by-step explanation:

Let the number = x

8x - 13 = 4x + 3              Add 13

8x = 4x + 3 + 13             Combine

8x = 4x + 16                   Subtract 4x

8x - 4x = 16                    Combine

4x = 16                           Divide by 4

x = 16/4

x = 4

2y (4 - x) = x/2 where x= 2
ICE Princess25 [194]
Hello!

2y(4-x)=x/2 

<span>[plug in 2 for x] </span>
<span>2y(4-2)=2/2 </span>

<span>[4-2 is 2, 2/2 is 1] </span>
<span>2y(2)=1 </span>

<span>[divide both sides by 2] </span>
<span>2y=1/2 </span>

<span>[divide by 2 again] </span>
<span>y=1/4 
</span>
====>So As Result As We See, y = 1/4.<====

Hope this Helps! Have A WONDERFUL Rest Of Your Day! :)

Choose which function is represented by the graph A. f(x) = (x - 1)(x + 2)(x+5)(x+10)
Trava [24]

Answer:

Option B

Step-by-step explanation:

From the graph attached,

x-intercepts of the graph are x = -1, 2 and 5

y-intercept of the graph is y = 10

Since, x intercepts of a graph define the zeros of the function (y = 0)

Therefore, (x + 1), (x - 2) and (x - 5) are the zero factors of the given graphs.

And the equation of the function will be,

f(x) = a(x + 1)(x - 2)(x - 5)

Since, -intercept of the function is y = 10

Therefore, for x = 0,

y = a(0 + 1)(0 - 2)(0 - 5) = 10

a(10) = 10

a = 1

So the function representing the graph is,

f(x) = (x - 1)(x + 2)(x - 5)

Option B will be the answer.
