Answer:
With an enlargement the scale factor would be greater than zero. With a reduction the scale factor would be a fraction or maybe even a decimal.
Answer:
there are infinite answers because the equation 12x+8=12x+8 is a true statement
Step-by-step explanation:
Answer: y = -4x/5 + 13
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m represents the slope of the line.
The equation of the given line is
y = 5x/4 - 2
Comparing with the slope intercept form, slope = 5/4
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line passing through (10, 5) is - 4/5
To determine the y intercept, we would substitute m = - 4/5, x = 10 and y = 5 into y = mx + c. It becomes
5 = - 4/5 × 10 + c
5 = - 8 + c
c = 5 + 8 = 13
The equation becomes
y = -4x/5 + 13

the image isnt showing can you type in the question ill answer it
Step-by-step explanation:

Recall that

Let

, so that


Since the angle

lies in the second quadrant, you know that the cosine must be negative, so
