Explain step by step of how you would find the scale factor for the following problem.
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.

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?
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.

A.2/3
B.3/4
C.4/6
--------------------------------
32/48
Divide the numerator and denominator by 16:2/3
<3
Answer:
A. 2/3
Step-by-step explanation:
32 = 2 x 16
48 = 3 x 16
32 / 48
= ( 2 x 16 ) / ( 3 x 16 )
= 2 / 3

ABCD is a parallelogram and X and Y are any point on CD and AD respectively. Prove that triangle AXB and triangle BYC are equal in area. Prove that
Answer:
See answer below
Step-by-step explanation:
ABCD is a parallelogram Given
BC ≅ AD; AB ≅ DC opposite sides of a parallelogram ≅
Δ AXB = 1/2 (AB)(AD) Formula for the area of a Δ
Δ BYC = 1/2 (BC) (DC) Formula for the area of a Δ
1/2 (AB)(AD)= 1/2(BC)(DC) Substitution
∴ Area of Δ AXB = Area of ΔBYC
Select the correct answer.
Which expression is a factor of this polynomial?
13 + 2x^2-9x-18
O
O A. (x - 2)
B. (x + 1)
Oc. (x - 6)
D. (x + 2)
Answer:
i think i'ts D. (x +2)
Step-by-step explanation:
A line passes through point A (12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A . Use point A to write an equation of the line in point-slope form.
The answer is 18, 0

How can you use factoring to solve quadratic equations in standard form?
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.

Write the equation of the line with x-intercept 3 and passing through the point (5.4)
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
