Hello!
Since the angles are same side alternate angles they are equal to each other
60 - 2x = 70 - 4x
We solve this algebraically
Add 4x to both sides
60 + 2x = 70
Subtract 60 from both sides
2x = 10
divide both sides by 2
x = 5
Hope this helps!
The correct answer is D, since if you simplify the equation 11 + 4 < -8 you get x < -2. Since -2 is greater than x, the arrow would need to point to the left signifying that it is a lesser value.
Answer:
Area of polygon = 42.63 mm²
Step-by-step explanation:
Given:
To find the area of the polygon (rectangle), multiply the length with the width.
⇒ Area of polygon = LW
<u>Substitute the values into the area:</u>
⇒ Area of polygon = (8.7)(4.9) [L = 8.7 mm; W = 4.9 mm]
⇒ Area of polygon = 42.63 mm²
Function 1: f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 + 1
Vertex = (4, 1)
function 2: f(x) = -x^2 + 2x - 15 = -(x^2 - 2x + 15) = -(x^2 - 2x + 1 + 15 - 1) = -(x - 1)^2 - 14
vertex = (1, -14)
Larger maximum is f(x) = -x^2 + 8x - 15
