X=10 and X=3/4 basically it’s whatever X equals to make the inside the parentheses equal zero. So if I were to plug 10 into the first parentheses you’d have 10-10 which equals zero. Also the zero has to the the opposite sign of what’s in the parentheses. So if -10 is in the parentheses then the zero has to be the opposite so positive 10.
Answer:
The ratio is 4/11
Step-by-step explanation:
Let
x ----> the total number of students in a school
we know that
1) 2/3 of the students study a language.
so
(2/3)x ----> number of students studying a language
and
x-(2/3)x=(1/3)x ---->number of students who do not study a language
2) Of those who study a language 2/5 were studying french
so
(2/3)x(2/5)=(4/15)x ----> number of students studying French
and
(2/3)x(3/5)=(6/15)x ----> number of students studying a language but not studying French
3) we know that
The number of students who do not study French is equal to the number of students who do not study a language plus the number of students who study a language but do not study French.
(1/3)x+(6/15)x=(11/15)x ----> number of students who not study French
(4/15)x ----> number of students who study French
4 ) Find the ratio of students who study french and who do not
(4/15)x/(11/15)x=4/11
The line 6x - 2y = 12 goes through -6 on the y-axis and 2 on the x-axis ie through (0, -6) and (2, 0)
The line will be solid and shaded above (towards the origin)
There are an infinite number of choices for the example points!
Here is my selection.
(0, 0) is in the solution set. 6 x 0 - 2 x 0 = 0 which is less than 12
(5, 0) is not in the solution set. 6 x 5 - 2 x 0 = 30 which is greater than 12
(2, 0) is on the line. 6 x 2 - 2 x 0 = 12
Answer:
- Infinitely many solutions
Step-by-step explanation:
- 2x + x + 4 = 3x + 4
- 3x + 4 = 3x + 4
Both sides of the equation are exactly same.
It means regardless the value of x the equation is true.
The equation has infinitely many solutions.
