Explanation:
Regardless of the number of factors, the product will be negative if an odd number of factors are negative.
In the example, 3 of the factors are negative. 3 is an odd number so the product will be negative.
-2*-3*-1*1 = -6
_____
Of course, the product will be zero if any factor is zero, regardless of the signs of any other factors.
Step-by-step explanation:
Since SP=TR, the differnce of PR and ST 24-15 divided by 2 is the length of PD (4.5)
Try to understand the rest from the attached picture
y = log(3x + 4) + 2
__________________________________________________________
Y-INTERCEPT: set x = 0
y = log(3(0) + 4) + 2
y = log(0 + 4) + 2
y = log( 4) + 2
Using calculator,
y = log( 4) + 2
y ≈ 2.60 when x = 0
__________________________________________________________
X-INTERCEPT: set y = 0
y = log(3x + 4) + 2
0 = log(3x + 4) + 2
-2 = log(3x + 4)
(it's simple. Always remember that the base is 10, even though there seems to be no "smaller number" next to log)
= 3x + 4
- 4 = 3x
[
- 4 ] /3 = x
x = -1.33 when y = 0

<h3>ANSWER: y-intercept is 2.60 and x-intercept is -1.33</h3>
