Answer:
<h3>x = 3</h3>
Step-by-step explanation:
Based on similar triangle;
14/49 = x+5/9x+1
Cross multiply
49(x+5) = 14(9x+1)
49x + 245 = 126x + 14
49x - 126x = 14 - 245
-77x = -231
x = -231/-77
x = 3
Hence the value of x is 3
Answer:
y = -1/2x - 3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Determine known variables
Slope = -1/2 (m = -1/2)
y-intercept - (0, -3), so b = -3
Step 2: Write in known variables
y = -1/2x - 3
2 inches.
Each square is 1/2 inch, so 4 squares is 2 inches.
Answer:
7x-4y=-8.........(i)
y=3/4x-3........(ii)
Putting the value of y in eqn(i)
7x-4y=-8
or, 7x-4(3/4x-3)=-8
or, 7x-3x+12=-8
or, 4x=-8-12
or, x=-20/4
x=-5
again,
putting the value of x in eqn(ii)
y=3/4x-3
y=-5(3/4) -3
y=-15/4 -3
y=-3/4
x=-5
y=-3/4
