Answer: C. Rectangles 1 and 3
Step-by-step explanation:
1. By definition, two rectangles are similar if they have equal shape bot do not have equal sizes.
2. You can know it the rectangle 1 and 3 are similar by the following proportions:
Where is the lenght of the rectangle 1, is the lenght of the rectangle 2, is the width of the rectangle 1 and is the width of the rectangle 2.
3. Subtitute values:
4. Then, the rectangle 1 and 3 are similar.
Answer:
the prduct of 1/2*6/5 is bigger
Step-by-step explanation:
1/2 x 6/5 = 6/10 = 3/5
1/2 x 5/6 = 5/12
Answer:
Step-by-step explanation:
1. ok so 2/3 is the rise over run for x so then 1 is the intercept so the first set of coordinates would be (-1,0) then you would use the rise over run and go up two and over three so the second set of coordinates would be (1,3) and so on
and im not a hundred percent sure on number two
Answer:
yes
Step-by-step explanation:
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 8 ← is in slope intercept form
with slope =
y = - x + 3 ← is in slope- intercept form
with slope = -
Now
× - = - 1
Hence the 2 lines are perpendicular
Answer:
The equation of the line would be y = -1/3x - 4
Step-by-step explanation:
In order to find this, we first need to find the slope of the original line. We do this by solving for y.
2x + 6y = 10
6y = -2x + 10
y = -1/3x + 5/3
Now that we see the slope as -1/3, we know the new line will have the same slope thanks to the definition of parallel lines. So, we can use this slope and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - -5 = -1/3(x - 3)
y + 5 = -1/3x + 1
y = -1/3x - 4
