Answer:
31.57 cars is the answer rounded to the hundredth, but since its cars you might want to put just 31 since half a car cant pass through. it depends on what your teacher wants really.
Step-by-step explanation:
70=2.1n+3.7
70-3.7=2.1n
66.3=2.1n
66.3/2.1=n
31.57=n
Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
Current area is 5ft * 10ft = 50ft^2.
Increasing by x, you have:
Since length must be positive,
Answer:
5) Domain: -3,-2,1,2,5 Range: 0,1,4,-5
7) Domain: -2 ≤ x ≤2 Range: 1 ≤ y ≤ 5
9) Domain: -4 ≤ x ≤ 3 Range: -5 ≤ y ≤ 5
10) Domain: all real numbers Range: y ≥ -3
12) Domain: -3 ≤ x ≤ 3 Range: -2≤ y ≤ 4
Sorry I don't know number 11
Answer:
Step-by-step explanation:
I have "and" but not "or"
"and" is when your talking about the decimal point for example:
