Answer:
y=0,y=7/5,y=-9/4
Step-by-step explanation:
12y(5y-7)(4y+9)=0
Using the zero product property
12y =0 (5y-7) =0 (4y+9)=0
12y/12 =0/12 5y-7 +7 =0+7 4y+9-9=0-9
y =0 5y = 7 4y = -9
5y/5 = 7/5 4y/4 =-9/4
y = 7/5 y =-9/4
2x-3=6
2(3)-3=6
multiply the parenthesis
6-3=6
I hope this helped (:
Answer:
D. 54,900
Step-by-step explanation:
We have been given that the salary of teachers in a particular school district is normally distributed with a mean of $50,000 and a standard deviation of $2,500.
To solve our given problem, we need to find the sample score using z-score formula and normal distribution table.
First of all, we will find z-score corresponding to probability using normal distribution table.
From normal distribution table, we get z-score corresponding is .
Now, we will use z-score formula to find sample score as:
, where,
= Z-score,
= Sample score,
= Mean,
= Standard deviation
Therefore, the salary of $54900 divides the teachers into one group that gets a raise and one that doesn't.

Steps to finding the line in the diagram with the format 'ax + by = c
1. Find the slope
- To find the slope, we need any two points on the line --> (0,4) and (3,0)
2. Set up, with any one point on the line and the slope, in point-slope form
