Answer:
<h2>y = -35x + 105</h2>
Step-by-step explanation:
The given graph represents a function between hours and miles.
To determine the equation that belong to this graph, first we need to find the slope using two points from the graph: (0, 105) and (3, 0).
The definition of slope is
Notice that the slope is -35. Remember that the slope is always the coefficient of variable . So, the choice that has this slope is the right answer.
Therefore, the right answer is the last choice: y = -35x + 105
Answer:
B
Step-by-step explanation:
<span>Figure WXYZ is a rectangle that has a semicircle added to its base. The rectangle has a length of sixteen inches and a width of seven inches. The semicircle has a diameter equal to the length of the rectangle.
Given:
Rectangle: Length = 16 inches ; width = 7 inches
Semicirle added to its base, the length of the rectangle. Only one length.
We need to get the circumference of the semi circle and add the length and 2 widths of the rectangle.
Circumference of a circle = 2</span>πr ⇒ 2 * 3.14 * 8 inches = 50.24
Circumference of a semicircle = 50.24/2 = 25.12 inches
Widths of the rectangle = 2 * 7 inches = 14 inches
Perimeter of the figure = 25.12 in + 14 in + 16 in = 55.12 inches.
Answer:
It's B
... because if you evaluate it it'll be 9x - 6xy, and 2xy + 2x^2
-6xy and 2xy are like terms
