What is a simpler form of the following expressions?
(7m2 - 5)(7m2 + 5)
(This is a rushed one so pls help?)

Answers

Answer 1

Answer:

49m^4 - 25

Step-by-step explanation:

The simpler expression can simply be found by expanding

The kind of expansion we have here is the difference of two squares

(a + b)(a-b) = a^2 - b^2

Thus, we have it that;

(7m^2-5)(7m^2 + 5)

=

49m^4 - 25

What is 3 x 3 x 3 x 3 is exponet form

Answers

it would be 3 to the power of 4 so 3^4

Answer:

3^4, or you could say three to the fourth power.

An exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. 3 x 3 x 3 x 3 is equivalent to 3^4 because you are multiplying three four times.

*Warning: 3 x 3 x 3 x 3 is NOT 3 x 4!!!*

So please help me with this!!

Answers

Answer:

The slope is undefined.

Hence, option C is true.

Step-by-step explanation:

The graph represents a vertical line.

We know that the slope of a vertical line is undefined.

Verification:

Taking two points

(0, -2)

(0, -4)

Finding the slope between (0, -2) and (0, -4)

slope = m = y₂-y₁ / x₂-x₁

                = [(-4-(-2))] / [(0-0) ]

                = [-4+2] / 0

                 = -2 / 0

                  = ∞

Thus, the slope is undefined.

Hence, option C is true.

A martial arts studio offers
beginner and advanced lessons. The
beginner lessons cost $7 less than
half the cost of the advanced
classes. Mrs. Turner paid for 4
beginner classes and 3 advanced
classes and spent $118. Let x be the
cost of the beginner classes and y be
the cost of the advanced classes.

Answers

Answer:

47

Step-by-step explanation:

The cost of beginner classes is $7.6 and the cost of the advanced classes is $29.2

What  are the four basic algebraic operations?

Addition, subtraction, multiplication, and division are the four basic algebraic operations.

Given that, x is the cost of beginner classes, and y is the cost of advanced classes.

The relationship between beginner classes and advanced classes is

x=0.5y-7

4x+3y=118

From the first equation, we can write

y=2x+14

Using this equation, we can write

4x+3(2x+14) =118

10x+42=118

i.e x=7.6

Substituting the value of x in the equation y=2x+14, we get

y=(2*7.6)+14

i.e y=29.2

The cost of beginner classes is $7.6, and the cost of advanced classes is $29.2.

Determine whether the relation y^2 - 4x = 3 represents y as a function of x ​

Answers

Answer:

The relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

Step-by-step explanation:

Consider the relation

[tex]y^{2} - 4x = 3[/tex]

[tex]y=\pm \sqrt{4x+3}[/tex]

Thus, the equation [tex]y=\pm \sqrt{4x+3}[/tex] does not represent function because there is at least one x-value with two or more values.

For example, if you look at the attached graph,

at x = 0, y = 1.73

at x = 0 , y = -1.73

It means the same input is generating two outputs; also if we draw a vertical line on the graph, the vertical line would intersect the graph more than once.

Please check the red vertical line on the graph would intersect the graph more than once.

Therefore, the relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.
