Step-by-step explanation:
1. is y= 3 x +8
-3 x + y - 8= 0
y = 3x+ 8
2. is in the pictures
3.
3 X + 5 y - 10 = 0
Real solution:
y = 2 - (3 X)/5
Solution:
y = 2 - (3 X)/5
Integer solution:
X = 5 n, y = 2 - 3 n, n element Z
Solution for the variable y:
y = 1/5 (10 - 3 X)
Answer:
7920 square feet.
step -by- step explanation.
From the the question, the
Length, l= 120 feet.
Width, w= 55% of l
This implies that;
w=0.55×120=66 feet.
Area of rectangle is given by the relation ;
By substitution,
Therefore the area of the rectangular stage is 7920 square feet.
