Answer:
x = 1, y = 3
Step-by-step explanation:
x = y - 2, so y = 4 (y - 2) -1
solve normally now
y = 4 (y - 2) -1
y = 4y - 8 - 1 (distribute)
y = 4y - 9 (simplify)
+9 -y -y +9
9 = 3y
3 = y
y - 2 = x
(3) - 2 = x
x = 1

Express as decimal
Answer:
3/5 of the students in the class are not in accounting majors
Step-by-step explanation:
The total number of males in the class is 3/8
3/5 of them are accounting majors
The ones who are not in accounting majors are;
3/8 - 3/5 = 9/40
The total number of female students in the class is;
8/8 - 3/8 = 5/8
1/4 of them are accounting majors
The ones who are not in accounting majors are;
5/8 - 1/4 = 3/8
Total number of students not in accounting majors;
9/40 + 3/8
= 24/40
= 3/5
Answer:
intersection is what point satisfies both equaitons
divide second equation by 2 for simplificy
2x-y=8
oh dear, we got the same equation
therefor they are the same line
infinitely many points
anywhere on the line 2x-y=8
some points are
(4,0)
(5,2)
Answer:
The dimension of the sandbox is (2x+1) by (x - 3)
Step-by-step explanation:
It seems the complete question will be:
The area of sandbox in park is represented by 2X^2-5x-3 find the dimensions of the sandbox in terms of x.
Step-by-step explanation:
From the question, the given expression is 2X^2-5x-3. This can be rewritten as
If the area of the sandbox in park is represented by this expression, then the dimensions of the sandbox will be the product of the factors. To determine the factors, we will factorize the given quadratic expression.
Factorizing the expression , we get
Hence, the dimension of the sandbox is (2x+1) by (x - 3)
