Answer:
Slope is -4
Y-intercept is -3 or (0, -3)
Step-by-step explanation:
y= mx + b
m = slope
b = y-intercept
12x + 3y = -9
3y = -12x - 9
y = -4x - 3
10, because when you add 5 and 7 then subtract 10 it equals 2
3.12 (repeating) = 3 12/99 reduces to 3 4/33 or 103/33
if there is one number repeating, like 0.222...u put that one number over 9...making it 2/9.
if there is 2 numbers repeating, like 0.1313...u put the two repeating numbers over 99...making it 13/99
if there are 3 numbers repeating, like 0.123123...u put ur three repeating numbers over 999...making it 123/999

L = 10a + a
L = 11 a
W = 1/10 (11a)
W = 1.1 a
Perimeter = 2(L + W)
Perimeter = 2*(11a + 1.1a)
Perimeter = 22a + 2.2 a
Perimeter = 24.2 a
Area = L * W
Area = 11a * 1.1a
Area = 12.1 a^2
The perimeter is 2*area
P = 2*A
P = 2* 12.1 a^2
P = 24.2 a^2
Now put in the perimeter on the left side of the above equation.
24.2a = 24.2 a^2 Divide both sides by 24.2
1 a = a^2 Divide by a
1 = a
The length = 11*a = 11*1 = 11
The Width = 1.1 a = 1.1 * 1 = 1.1
