Answer:
Interpreting as: X=a-sqrt b X=a+sqrt b
Input:
X = a - sqrt(b) X = a + sqrt(b)
Alternate forms:
{a = (sqrt(b) + 1) X, a = X - sqrt(b), b = 0 ∨ X = -1}
{a = (sqrt(b) + 1) X, a + sqrt(b) = X, sqrt(b) (X + 1) = 0}
Answer:
q=12
Step-by-step explanation:
-11=61-6q
-11-61 =-6q
-72=-6q
q=72/6
q=12

probability that the second tennis ball is green:
probability that the third tennis ball is red:
Answer:
Length = 0.8m
Breadth = 0.3m
Volume = 108litres = 108÷1000 = 0.108m³
Volume = l x b x h
0.108 = 0.8 x 0.3 x h
0.108 ÷ ( 0.8 x 0.3 ) = h
0.45 = h
Answer:
y = -x+3
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 2 - -3)/( 1 - 6)
( 2+3)/( 1-6)
5/ -5
-1
The slope is -1
We can use slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -x+b
Substitute a point into the equation
2 = -1 +b
Add 1 to each side
2+1 = -1+1+b
3 = b
y = -x+3
