Answer: D
Step-by-step explanation:
D is the only one that states the correct slope
Answer:
y = -4x + 10
Step-by-step explanation:
I am going to assume you are trying to write the equation of a line.
4x + y = 10
4x - 4x + y = 10 - 4x
y = -4x + 10

Step-by-step explanation:
Area = perimeter + 132.
Let each side of the city be x miles long, then:-
x^2 = 4x + 132
x^2 - 4x - 132 = 0
x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2
x = 13.66, -9.66 We ignore the negative
So the city has dimension of 13.66 * 13.66
13.7 * 13.7 to nearest 10th
Answer:
252 cm^2
Step-by-step explanation:
Let x be the length
and
y be the width of rectangle
Then, the area will be:
If the length and width are changes by a scale factor 1.5.
Then the area will be:
We already know that xy=112
So the new area will be:
