slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m = [tex]\frac{-2-0}{0-(-2)}[/tex] = [tex]\frac{-2}{0+2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1

In kick boxing, the force needed to break a board varies inversely with the length of the board.If it takes 5 pounds of pressure to break a board 2 feet long, how many pounds of pressure will it take to break a board that is 8feet long?
Answers
Answer:
Step-by-step explanation:
By taking k as constant:
P = k/L (where P is pressure, and L is length)
5 = k/2
k = 10
Therefore:
P = 10 / L
P = 10/ 8
P = 1.25 Pounds.

Write the equation of the line with x-intercept 3 and passing through the point (5.4)
Answers
Answer: y=(1/5)m+3
Step-by-step explanation:
Start with the standard form of an equation of a straight line: y=mx+b, whre m is the slope and b the y-intercept (the value of y when x=0).
y=mx+b
We know b (3), so:
y=mx + 3
To find the slope, m, we can use the one given point, (5,4):
y=mx + 3 for (5,4) would be:
4 = m*5+3
1 = 5m
m = (1/5)
y=(1/5)m+3

1. Start at point (0,0), This point is where the x-y-axis meet. Do not put a dot
there because this is your starting point.
2. Move to the left over to point -1 3/4 . This place is between -1 and -2, and
closer to -2 because the point is -1 .75. Remember this point is not on the
graph.

if ab=12 and a^2+b^2=25 ,then what is (a+b)^2=
Answers
I think it’s a^2+2ab+b^2
Answer:
49
Step-by-step explanation:
Multiply out (a+b)^2
(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,
= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values
=25 + 2(12) = 25 + 24 = 49
So (a+b)^2 = 49

We have to find the value of expression ?
Explanation:-
Given that
[(1/2)²-(1/4)³]
⇛ [{(1/2)×(1/2)}-{(1/4)×(1/4)×(1/4)}]
⇛ [{(1×1)/(2×2)}-{(1×1×1)/(4×4×4)}]
⇛ [(1/4)-(1/64)]
LCM of 4 and 64 = 64
⇛ [(1×16)-(1×1)]/64
⇛ (16-1)/64
⇛ 15/64
The value of the given expression is 15/64.

Explain step by step of how you would find the scale factor for the following problem.
Answers
Answer:
Scale factor = 2.5.
Step-by-step explanation:
Work out the lengths of the corresponding sides.
The scale factor is the ratio of one side to the other.
Take the smallest length in both triangles.
Blue triangle:
length = √((7.5-2.5)^2 + (12.5-5)^2) = 9.0139 units.
Red triangle:
length = √((3-1)^2 + (5-2)^2) =3.6056
So the scale factor
= 9.0139/ 3.6056
= 2.5.
How can you use factoring to solve quadratic equations in standard form?
Answers
Step-by-step explanation:
The roots or the zeroes of a quadratic equation are its x-intercepts, which are the points on the graph where it crosses the x-axis. When a quadratic equation is in standard form, ax² + bx + c, the usual goal is to find the binomial factors that could help us determine the roots or solutions to the given equation. Once you find the factors, then you will use the Zero-Product Property to solve for the solutions.
For example, if you were given the following quadratic equation in standard form, x² + 6x + 8 = 0, and were tasked to find its factors.
x² + 6x + 8 = 0
where a = 1, b = 6, and c = 8:
In order to find the factors of the given quadratic equation, we must find the factors with a product ac, and sum b.
Using 2 and 4 as possible factors produce a product that is equal to
product of ac: 2 × 4 = 8
sum of b: 2 + 4 = 6.
Therefore, the factors of the given quadratic equation, x² + 6x + 8 = 0 are:
(x + 2) (x + 4).
Using the Zero-Product Property, where it states that for any real numbers, u and v, if uv = 0, then u = 0 or v = 0.
Thus, setting the binomial factors of the given quadratic equation to zero will provide the solutions.
(x + 2) (x + 4)
x + 2 = 0
x + 2 - 2 = 0 - 2
x = -2
x + 4 = 0
x + 4 - 4 = 0 - 4
x = -4
Therefore, the solutions to the quadratic equation, x² + 6x + 8 = 0 are x = -2, and x = -4.
