Check the picture below.
notice, this line, in black, is really just a vertical line, namely x = -4.
a perpendicular line to that, like the red line there, will be a horizontal line y = [some number].
recall a vertical line always has an <u>undefined</u> slope, whilst a horizontal line always has a slope of 0.
Answer:
A
Step-by-step explanation:
Consider Δ JKL and Δ GDF
If the ratios of corresponding sides are equal then the triangles are similar.
= =
= =
= =
Since the ratios are equal then Δ JKL and Δ GDF are similar by SSS postulate.
Answer: B)
Step-by-step explanation:
Since, the wheel covers a distance of inches in one second.
Thus, its linear velocity =
Also, the radius of wheel = 10 inches,
Hence its angular velocity =
⇒ Option B is correct.
The statements that correctly represent the scenario stated are:
B. because losing 8 pounds is represented as -8 and doing this for 3 months would be 3 groups of -8 or 3 x -8
D. because they showed the weight loss as a negative integer and then put those into groups of 4 each using the distributive property)
The error with the other 2 choices is that the negative number is not correctly representing which part of the problem is a decrease. The negative sign is placed on the number of groups of.
