Answer:
The third box, the fourth box, and the second box
Step-by-step explanation:
The first segment that describes Part A is the one that is increasing because based on the information, the airplane <em>climbs</em>, meaning it's going up.
The second segment that describes Part B is the one that is a straight horizontal line, and this is because the airplane is flying at a <em>constant</em> rate, so it will be straight.
The third segment that describes Part C is the one that is decreasing (going down) slowly. This is because the airplane is down <em>descending</em>, which is also means going down.
Answer:the length of the rectangle is 36 feet
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The length of a rectangle is equal to three times its width. This means that
L = 3W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter is equal to 96
feet, it means that
2(L + W) = 96
L + W = 96/2 = 48
Substituting L = 3W into L + W = 48, it becomes
3W + W = 48,
4W = 48
W = 48/4 = 12
L = 3W = 3 × 12 = 36
Answer:
7
Step-by-step explanation:
Answer:
8x - 7y = 56
Step-by-step explanation:
in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7
so 8x - 7y = 56
-7y = 56 - 8x
y = 56/-7 -8x/-7
y = -8 + 8/7 x
When we add or subtract polynomials, the addition or subtraction is applied to the coefficients of the terms of equal powers.
For the given polynomials, we are required to do subtraction as follows:
(-4.1 x^2 + 0.9 x - 9.8) - (1.7 x^2 - 2.4 x - 1.6)
= -4.1 x^2 + 0.9 x - 9.8 - 1.7 x^2 + 2.4 x + 1.6
= (-4.1-1.7) x^2 + (0.9+2.4) x + (-9.8+1.6)
= -5.8 x^2 + 3.3 x - 8.2
The final expression (solution) is:
-5.8 x^2 + 3.3 x - 8.2
