Answer: 10
Step-by-step explanation:
25 + 20= 45
45 + ? = 6:00
A= 15
1. x = 25 inches
2. Triangle c
Answer:There is a relationship between study hours and test score. As the hours of studying increase, the test scores increase.
Step-by-step explanation:
From the given scatterplot in which Mackenzie investigated the relationship between the number of hours studying and the test score for some of the students in her class.
We can see that the dots are increasing in the right and go upward with respect to time.
It shows there is a relationship between the test score and hours of studying.
As the hours of studying increase, the test scores increase .
Answer:
B.
Step-by-step explanation:
Answer:
All the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Given - A triangle is to be dilated with the origin as the center of dilation and with a scale factor of 2.
To find - Which answer choice correctly maps this dilation algebraically?
Proof -
Let ABC is a triangle where A, B, C are the vertices of the triangle respectively.
Now,
Let the coordinates be (x, y)
If a triangle is to be dilated with the origin as the center of dilation and with a scale factor of a , then the coordinated be changes as
(x, y) ⇒ (ax, ay)
Here given , a = 2
So, all the coordinates are changed to
(x, y) ⇒ (2x, 2y)
