Step-by-step explanation:
For y-intercept, x = 0:
Answer:(-3,-6)
Step-by-step explanation:
-4x+y=6
+ -5x-y=21
_________
-9x. = 27
X= 27/-9
X = -3
-4(-3)+y=6
12+y=6
Y=6-12
Y= -6
To check
-4(-3)+(-6)=6 and -5(-3)-(-6)=21
12-6=6. 15+6=21
6=6. 21=21

Answer:
25.2X + 3.4 centimeters.
Step-by-step explanation:
The formula for the perimeter of a rectangle
= 2L + 2W
= 2(L + W)
From the question:
Width of a rectangle (W) = 9.7 X - 4.7 centimeters
Length of a rectangle (L) = 2.9 X + 6.4 centimeters
Imputing it into the formula
2(L + W)
2( 9.7X - 4.7 + 2.9X + 6.4)
2 (9.7X + 2.9X - 4.7 + 6.4)
2( 12.6X + 1.7)
= 25.2X + 3.4 centimeters.
Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.
