Answer:
D. ÷ 3
Step-by-step explanation:
We can use any numbers for x to see what would happen to y:
If x was 5, y would be 1 (because 5 ÷ 5 = 1). Now, if we tripled x and made it 15 (5 × 3 = 15), y would be 1/3 (because 5 ÷ 15 = 1/3).
This means that the value of y divides by 3, option D
Hope this helps!
No. you are cheeting! you should do by your self, i can nelp you some of problem
Answer:
see explanation
Step-by-step explanation:
Given
(5y + 6)² = 24 ( take the square root of both sides )
5y + 6 = ± 
= ± 2
( subtract 6 from both sides )
5y = - 6 ± 2 ( divide both sides by 5 )
y = 
and y = 
The period of y = 4 cos(8πx) is 2π/(8π) = 1/4, since
cos(x - 2π) = cos(x)
and if we replace x with 8πx, we get
cos(8πx - 2π) = cos(8πx)
and
8πx - 2π = 8π (x - 1/4)
Answer:
Step-by-step explanation:
Q2:
The point-slope form of an equation of a line:
m - slope
The formula of a slope:
We have the points (4, 6) and (6, 10). Substitute:
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>subteact 2 from both sides</em>
Q4:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
Put the slope m = 3 and the coordinateso f the point (-2, 6) to the point-slope form of an equation of a line:
<em>use distributive property</em>
<em>add 6 to both sides</em>
