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

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.
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.

Step-by-step explanation:
A line sloping upwards from left to right has a positive slope.
Line 1 is in this category.
A line sloping downwards from left to right has a negative slope.
Line 4 is in this category.
The slope of a vertical line, parallel to the y- axis is undefined.
Line 2 is in this category.
The slope of a horizontal line, parallel to the x- axis is zero.
Line 3 is in this category.

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

Write an equation to find the value of x so that each pair of polygons has the same perimeter. Then solve
The Pythagoras Theorem:
the base squared and height squared added is equal to the hypotenuse squared.
so
(x+6)² + (x+3)²= (x+9)²
x²+36+12x+x²+9+6x = (x+9)²
2x²+45+18x=x²+81+18x
x²=36
x=√36
X= 6
now
(x+6)= 12
(x+3)=9
(x+9)=15

What is the solution to 5(x-1)+3x=7(x+1)
Answer: x = 12
Step-by-step explanation:
5(x-1)+3x=7(x+1)
5x - 5 + 3x = 7x + 7
8x - 5 = 7x + 7
x - 5 = 7
x = 12

What is 3 x 3 x 3 x 3 is exponet form
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!!!*
April wants to multiply 6 and 42 using the distributive property. Which of the following number sentences shows how
she could do it?
06x42 = 42 x6
06x(40+2) =(6x 40) + 2
O(6x42) x1=6x (42 ×1)
06x(40 +2) = (6x 4o) + (6
2)
Answer:
I'm pretty sure the answer is the last one;
6 x (40+2) = (6 x 40) + (6 x 2)
The 6 is distributed to the 40 and the 2

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.
