Answer:
y = -8
Step-by-step explanation:
-18+2 = 5y-3y
-16 = 2y
y = -8
If you need more explaining notify me
The answer is b:
First change the operation to multiplication, and then change the last fraction to it's reciprocal (7/15 / 5/3)
Then, you can simplify 15 and 5 to 3 and 1 (divide each by 3)
Finally u multiply (7*1 / 3*3)
Sorry if its bad first time
Answer:
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, <em>or</em><em> </em>insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
<em><u>Point-slope form:</u></em>
Where:
- is the slope
- and are corresponding coordinate points
Insert the given values:
Solve for y. Expand the right sie using the distributive property:
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
<em>OR</em>
<em></em>
<em><u>Slope-intercept form:</u></em>
Where:
- is the slope
- is the y-intercept
- and are corresponding coordinate points
Insert the given values:
Simplify the multiplication:
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
:Done
480700. The different combinations of students that could go on the trip with a total of 25 student, but only 18 may go, is 480700.
The key to solve this problem is using the combination formula . This mean the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.
The total of students is n and the only that 18 students may go is r:
