What are the vertices of triangle ABC'if triangle ABC is dilated by a scale factor of 2?
Answers
be because they are just divided by 2 than the actual coordinates
The vertices of triangle ABC' are A' (0, 20), B' (8,12), and C' ( 4, 4) if triangle ABC is dilated by a scale factor of 2.
How does dilation affect length, area, and volume of an object?Suppose a figure (pre-image) is dilated (dilated image) by a scale factor of k.
So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as a scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple of linear things twice grow by the square of the scale factor.
Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.
So the area of the first figure = k² × area of the second figure
The vertices of triangle ABC are
A (0, 10) , B (8 ,6), C ( 4, 2)
The vertices of triangle ABC' if triangle ABC is dilated by a scale factor of 2.
k = 2
L = k × M
L = 2 × 10 = 20
B = 2 × 6 = 12
W = 2 × 2 = 4
Hence, The vertices of triangle ABC' are A' (0, 20), B' (8,12), and C' ( 4, 4).

Find the slope and the y-intercept of the graph of the linear equation y=5/4x-7. The slope is ?, and the y-intercept is ?.
Answers
Answer:
Not Linear.
Step-by-step explanation:
Answer:
5/4 slope
-7 y intercept.
Step-by-step explanation:
The slope is the number in front of the x. The number in front of the x is 5/4. The slope is 5/4
1. The y intercept is whatever is behind the x or 0 if there is no number following the x.
2. The y intercept is also characterized by being on the same side of the equation as the x.
3. Finally it has no x in it.
In this case the y intercept is -7
Examples
y + 2 = x 2 is not the y intercept. subtract 2 from both sides. y = x - 2. Therefore -2 is the y intercept.
2y = 4x + 6 4 is not the slope. You have to divide by y = 2x+3. So 2 is the slope and 0,3 is the y intercept.
Nadia is a stockbroker. She earns 13% commission each week. Last week, she sold $4,500 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?
Answers
Multiply amount sold by commission rate:
4500 x 0.13 = 585
She made $585 last week.
Multiply amount made in 1 week by 52 weeks ( 1 year = 52 weeks)
585 x 52 = 30,420
She made $30,420 in 2011
Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. 28. __________ If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours?
Answers
Answer:
96 pizzas
Step-by-step explanation:
First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533
Convert 3 hours to minutes = 3 x 60 = 180 minutes
The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas
