40.21/12.5
We would do this because the problem asks for unit rate
And and we need to find out the cost for one square foot
40.21/12.5 = 3.2168
We need to round this ANSWER and round it or else it will be incorrect
The answer would round to 3.22
Therefore, the answer is $3.22 per square foot
Answer:
If the value of a is negative the line is decreasing.
Step-by-step explanation:
The value of a, the coefficient of x, is the slope.
If the slope is positive, the line is increasing from left to right.
If the slope is negative, the line is decreasing from left to right.
Answer:
Step-by-step explanation:
Choice a:
The order pair given is (<span>1, 3)
y-4x = 3-4(1) = -1
-1 is greater than -6
Therefore, this choice is wrong
Choice b:
</span>The order pair given is (-2, -14)
y-4x = -14-4(-2) = -6
-6 is equal -6
Therefore, this choice is correct
Choice c:
The order pair given is (-1, -9)
y-4x = -9-4(-1) = -5
-5 is greater than -6
Therefore, this choice is wrong
Choice d:
The order pair given is (3, 5)
y-4x = 5-4(3) = -7
-7 is less than -6
Therefore, this choice is correct
Choice e:
The order pair given is (0, -5)
y-4x = -5-4(0) = -5
-5 is greater than -6
Therefore, this choice is wrong
keeping in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
