2x+y=1 can be rewritten as y=-2x+1, with the slope as -2 and the y-intercept at 1. The equation you can use for the table would be (x*-2)+1, or you can just use this:
-2=5
0=1
3=-5
(-2, 5)
(0, 1)
(3, -5)
Answer: A phase shift horizontal translation to the right.
Step-by-step explanation:
A periodic function that does not start at the sinusoidal axis or at a maximum or a minimum has been shifted horizontally. This horizontal movement allows for different starting points since a cosine wave does not have a beginning or an end.
In this question, the sinusoidal wave is a cosine function of F(x) = cos x.
So to change the parent cosine function to the cosine function above, A phase shift horizontal translation to the right must have been done.
Answer:
65% as a fraction would be 13/20
Step-by-step explanation:
Answer:
y = 0.1x + 200
Step-by-step explanation:
Independent variable (y-intercept) = $200
Dependent variable (Slope) = 0.1 (10%)
Why?
Since Dave's salary is fixed, the $200 he is earning is an independent variable. The commission <em>depends</em> on his weekly sales. The weekly sales is said to be "x". Since 10% is a dependent variable, it goes together with x.
Hello!
We are given that the measure of one angle is equal to 115 degrees (for convenience, we’ll refer to this angle as ∠W). Looking at the image above, we can see that ∠W and ∠Y are supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees, also known as a straight line. This relationship can be expressed using the following formula:
A1 + A2 = 180
Now insert any known values provided by the image above:
(115) + (∠Y) = 180
Subtract 115 from both sides of the equation:
∠Y = 65
We have now proven that ∠Y has a measure of 65 degrees. Now, looking at the image again, we can see that ∠W and ∠X are vertical angles. Vertical angles are two angles that lie on opposite sides of two intersecting lines. A pair of vertical angles is always equal in measure. This relationship can be expressed using the following formula:
A1 = A2
Now insert any known values provided by the image above:
(∠X) = (115)
We have now proven that ∠X has a measure of 115 degrees.
I hope this helps!
