Answer: 9x-3x and 5x+x
Step-by-step explanation:
1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.
2. Expressions A and C are equivalent.
3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.
I believe that the correct answer is 72

Answer:
x ≈ 9.6
Step-by-step explanation:
Δ ABC is right with ∠ C = 90° ( angle between tangent and radius )
Using Pythagoras' identity in the right triangle
x² + 14² = 17²
x² + 196 = 289 ( subtract 196 from both sides )
x² = 93 ( take the square root of both sides )
x = 
≈ 9.6 ( to the nearest tenth )
Answer:
$21
Step-by-step explanation:
Multiply 7 by 3, since it increased $3 each week for 7 weeks:
7(3)
= $21
So, the total change in the price of a share of stock was $21
slope: 4/5 is a positive slope
- positive slopes rises from left to right
- positive slopes falls from right to left
- neither horizontal or vertical.
The picture below shows some examples of <u>equation with positive slope</u>.
