Answer:
A
I Had that question before
Answer:
C
Step-by-step explanation:
First use distribution
4(3x+y)= 12x+4y
and
-2(x-5y)= -2x+10y
combine the 2 answers
10x+14y
Answer:
The answer is 49 in^2.
Step-by-step explanation:
The area of the triangle is 1/2* perpendicular height * horizontal length.
The horizontal length is 14 in, while the perpendicular height is 7 in.
The area of the triangle is 1/2* 7 in * 14 in = 49 in^2
The point of intersection of the two lines is at (1,-1)
<h3>System of equation</h3>
The given system of expression is shown below
x - 2y = 3
5x + 3y = 2
The solution to the system of equation is the point of intersection
From equation 1
x = 3 + 2y
Substitute into 2
5(3+2y) + 3y = 2
15 +10y + 3y = 2
13y = -13
y = -1
Substitute y = -1 into 3
x = 3 + 2y
x = 3+(-2)
x = 1
Hence the point of intersection of the two lines is at (1,-1)
