Answer:
According to the change-of-base formula, we can rewrite the log base 2 as a logarithm of any other base. Since our calculators can evaluate the natural log, we might choose to use the natural logarithm, which is the log base e.
Step-by-step explanation:
He had $12.50 left because you do
1.25 + 5= 6.25 and because he spent half earlier you would multiply by two to get 12.5
Answer:
a. x+ 6
c. 4x- 1
Step-by-step explanation:
4x2 + 23x -6
4x2 + (24-1)x -6
4x2 + 25x - x - 6
4x(x+6) -1 (x+6)
(x+6)(4x-1)
hope this helps have a great time :)
Answer: B
-14 - 2x - 10 + 3y + 8x - 16y
Put everything in order so it is easy to combine like terms.
-2x + 8x + 3y - 16y - 14 - 10
Combine like terms. That means that you should add both x's together, add both y's together, and add both numbers together.
6x - 13y - 24
B is your answer! If you are confused on why B looks different, it is becuase the variables/numbers are in mixed up places. I hope this helps you!
Answer:
Step-by-step explanation:
Observe what happens to y if we move from x = 1 to x = 9: y decreases by 2. Thus, the slope of the line in question is m = rise / run = -2/8, or -1/4.
Writing the equation in point-slope form, y - k = m(x - h), we get:
y - 7 = (-1/4)(x - 1) (point-slope form)
Solving for y results in the slope-intercept form:
y = 7 - x/4 + 1, or
y = (-1/4)x + 8 (slope-intercept form)
