Answer:
C
Step-by-step explanation:
A "zero" of a function is an input value that makes the function value equal zero. On the graph these input values are -3 and 1; you can see that the function values are zero in both cases. C is correct.
100%-> 2900
1%-> 2900/100
=29
29-> 1%
1595->?
1595/29=55
29->1%
1595->1 x 55
=55%
So, 55% is your answer !!
Hope this helps :)
Answer:
Rewrite the first equation as x = 36 – 3y.
Step-by-step explanation:
x + 3y = 36 (1)
4x + 5y = 9 (2)
Using substitution method
From (1)
x = 36 - 3y
Substitute x = 36 - 3y into (2)
4x + 5y = 9
4(36 - 3y) + 5y = 9
144 - 12y + 5y = 9
- 12y + 5y = 9 - 144
-7y = -135
y = -135 / -7
y = 19.3
There is an error with the second equation, 4x + 5y can not be equal to 9
Nevertheless, the first step when solving by substitution is:
Rewrite the first equation as
x = 36 – 3y.
