Answer:
5^9 is not a square number
Step-by-step explanation:
5^9 is not a square number because it is not 5^2, or a multiple of itself. 4^2 is a square number. 4x4=16. 5x5 definitely does not equal 1953125!
For both functions, we can use the rise over run formula to find the slope. Rise over run uses the following formula:

Function 1 has the points (0,4) and (3,0). Plug the x and y values into the formula:

Function 1 has a slope of -4/3.
We can take any two points from Function 2. We'll use (0,5) and (4,8). Plug the values into the formula:

Function 2 has a slope of 3/4.
Because the question asks for the steeper slope, we'll convert the slope of Function 1 into a positive number. The slope will now be 4/3.
Compare the slopes of both functions:
Function 1 has the steeper slope, -4/3.
This is how I would solve it:
1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14
To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
Answer:
4 is the length
Step-by-step explanation:
14 and 4
14 x 14 + 4 x 4 = 212
14 + 4 = 18
Side-angle-side similarity means that when two triangles have corresponding angles that are congruent and corresponding sides with identical ratios we can say that the triangles are similar. So UV/XY and WV/ZY are equivalent and therefore, angle V equals angle Y is the correct answer.
