Answer:
x = 1 and x = 
Step-by-step explanation:
In this equation, a=5, b=-1, c=-4.
Plug these into the quadratic formula:
x = 
and x = 
Now, simplify the equations:
x = 
= 
= 
= 1
and
x = 
= 
= 
=
Answer: 102
Step by Step Explanation:
5y+11=8y-13
-8 -8y
-3y+11=-13
-11 -11
<u> 3y </u>=<u> -24</u> = 8 y=8
3y 3y
5(8)+11=51
Multiple 51 times 2 and you're answer will be the following.
next three are n+2, n+4, and n+6
four consecutive odd have sum 56
n + n+2 + n+4 + n+6 = 56
4n + 12 = 56
4n = 44
n = 11
the numbers are 11, 13, 15, and 17
Answer:
Step-by-step explanation:consecutive integers are represented by x, x+1 , so for this problem the greater one is represented by x + 1.
Now you need to translate the problem. the greater is seven less than 1/3 the smaller
---> x + 1 = (1/3)*x - 7 ---> now solve for x (the smaller) and x+1 (the greater)
***hint: to get rid of fractions in an equation you can always multiply EVERYTHING by the denominator , 3 in this case
