Triangle ABC is a scaled copy of triangle DEF. Side AB measures 12 cm and is the longest side of ABC. Side DE measures 8 cm and is the longest side of DEF.
Triangle ABC is a scaled copy of triangle DEF with what scale factor?
Answer: scale factor = 1.5
Step-by-step explanation:
[tex]\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Side length of original figure}}[/tex]
Given: Triangle ABC is a scaled copy of triangle DEF.
Side AB = 12 cm and is the longest side of ABC.
Side DE = 8 cm and is the longest side of DEF.
[tex]\text{For similar triangles, Corresponding sides are proportional.}[/tex]
AB is corresponds DE (longest side of both triangles)
So, [tex]\text{Scale factor}=\dfrac{\text{AB}}{\text{DE}}=\dfrac{12}{8}=1.5[/tex]
Hence, the scale factor = 1.5.

44 = 2(3x - 5)
Answer:
x = 9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
44 = 2(3x − 5)
44 = (2)(3x) + (2)(−5) (Distribute)
44 = 6x + −10
44 = 6x − 10
Step 2: Flip the equation.
6x − 10 = 44
Step 3: Add 10 to both sides.
6x − 10 + 10 = 44 + 10
6x = 54
Step 4: Divide both sides by 6.
[tex]\frac{6x}{6} = \frac{54}{6}[/tex]
x = 9

The line whose slope will be same as that of the graph given, will be the line parallel to the given line.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is a graph of a line.
For a given line to be parallel to the given line, its slope should be same as that of the line plotted. Since the graph is not given, we can make an estimate for the equation of the line parallel to the given line. The four equations given will have their slopes as mentioned -
[A] - 4x + 5y = - 10 [m] = -4/5
[B] - 4x - 5y = 0 [m] = 4/5
[C] - 5x + 4y = 24 [m] = -5/4
[D] - 5x - 4y = -8 [m] = 5/4
Now, the line whose slope will be same as that of the graph given, will be the line parallel to the given line.
Therefore, the line whose slope will be same as that of the graph given, will be the line parallel to the given line.

Given the definitions of f(x) and g(x) below, find the value of g( f(1) ).
f(x)= 3x^2-7x+6
g(x)= 4x-5

Answer:
the answer is C, 0
Answer:
C) 0
Step-by-step explanation:
7(x + 2) = 7x - 10
First, we multiply within the parenthesis
7x + 2 = 7x - 10
Add 10 to both sides of the equation
7x + 12 = 7x
Subtract 7x from both sides of the equation
12 = 0
Because the answer is 0, that means there are 0 solutions and the equation can not be solved.
I hope that this helps! :)
