(x + 2) __x – 2__ = x2 - 4
Answer: x - 2

We can use the given to find the answer.

(x+2) times x = x^2 and 2 times -2 = -4

Therefore, (x+2)(x-2) = x^2-4

How do I find domain and range from a graph/equation?
likoan [24]

domain represents the x values so for example in a diagonal line that continues infinitely, the domain is all real numbers or (-infinity, infinity)

range represents y values so it would also be all real numbers or (-infinity, infinity)

let’s say there is a line (refer to pic) that moves ONLY from point (-3, -1) and (2, 2)

the domain would be [-3, 2]

we use brackets because it’s a real number unlike infinity (also because it’s a closed circle on the graph; if the graph had an open circle you would use a parenthesis)

and the range would be [-1, 2]

if you have any more questions about this explanation feel free to ask!

Referring to the figure, find the missing length.
vivado [14]

Answer:

5 units

Step-by-step explanation:

here;

perpendicular (p)= 3

base (b) = 4

hypotenuse (h) = c= ?

By Pythagorean relationship;

h²=p²+b²

or, h= √(p²+b²)

or, c= √(3²+9²)

or, c= √25

hence, c=5

Use the elimination method to find all solutions of the system:
weqwewe [10]

Answer:

x = 3    and    y = 4

Step-by-step explanation:

Given

[Correct Question]

x^2 - 2y = 1

x^2 + 5y = 29

Required

Solve using elimination

First, we eliminate x.

Subtract equation (1) from (2)

x^2 - x^2 + 5y - (-2y) = 29 - 1\\

5y - (-2y) = 28

5y +2y = 28

7y = 28

Divide through ny 7

y = 4

Take x^2 - 2y = 1

Make x^2 the subject

x^2 = 1 + 2y

Substitute 4 for y

x^2 = 1 + 2*4

x^2 = 1 + 8

x^2 = 9

Take square roots

x = \sqrt 9

x = 3

Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = 3/ square root of 3x + 4
Elis [28]
Well, your equation y=3/SQRT(3x+4) should be rationalized, but that's not what you want.

If f(x) = 3/SQRT(x+4) and g(x) = 3x

f(g(x)) then = 3/SQRT(3x+4), but rationalizing this = 3SQRT(3x+4)/(3x+4)
