Answer correctly! dropbox 1 options: a. (9.5, 0) b. (4.5, 0) c. (-9.5, 0) d. (-4.5, 0) dropbox 2 options: a. (0, 3) b. (0, 1) c. (0, -3) d. (0, -1)

(4.5,0)  x intercept

(0,-1)  y intercept

Step-by-step explanation:

f(x) = log (2x+1) -1

y = log (2x+1) -1

To find the x intercept, set y = 0 and solve for x

0 = log (2x+1) -1

Add 1 to each side

1 = log (2x+1)-1+1

1 = log (2x+1)

Raise each side to the power of 10

10^1 = 10^ log(2x+1)

10 = 2x+1

Subtract 1 from each side

10-1 = 2x+1-1

9 = 2x

Divide by 2

9/2 =2x/2

4.5=x

The x intercept is 4.5

(4.5,0)

To find the y intercept, set x = 0 and solve for y

y = log (1) -1

y = 0 -1

y = -1

The y intercept is -1

(0,-1)

x = 12

y = 15

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
