The interval over which the given quadratic equation decreases is: x ∈ (5, ∞).
<h3>How to find the interval of quadratic functions?</h3>
Usually a quadratic graph function decreases either when moving from left to right or moving downwards.
In the given graph, we can see that the coordinate of the vertex is (5, 4) after which the curve goes in the downward direction.
Thus, for the values of x greater than 5, the function decreases and so we conclude that the interval in which the quadratic equation decreases is: (5, ∞).

95°.
Since the angle inside of a triangle equal 180° we need to find the angles inside of the triangle. The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°.
Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
Hope this helps :)
Answer:
slope is 4/3 y intercept is -3
Step-by-step explanation:
there is no calculations needed
The greatest number of 1/3 meter long ribbons she will get is the quotient of dividing 3/4 by 1/3 while the remaining ribbon will be the remainder.
3/4 ÷ 1/3 = 3/4 x 3/1 = 9/4 = 2 1/4
Therefore, she will cut two 1/3 meter long ribbons and 1/4 meter long ribbon will remain from the original ribbon.
