Step-by-step explanation:
We are given:
This can be rewritten as
Next, we can bring the x's and y's to their respective sides by dividing by coty and x and then multiplying the dx to the other side. We can then change into . This gives us the differential
Now we can integrate each side
To integrate tan(y), we need to manipulate it
Now we can use u-substitution where
This gives us
Now, lets integrate both sides
Next, we can substitute our u value back in
Now we can add to the other side and subtract c from each side. This gives us
Next, we can apply a property of logarithms to combine this sum of two logs into one log.
Lastly, we can add a base e to each side to remove the ln
And here is our answer.
<span><span>A) Sally’s statement is sometimes true. The equations students write to support their answers will vary. Sample pairs of equations that support the answer “sometimes true” are as follows:
Sample addition equation:–6.2 + 5.71 = –0.49Sample subtraction equation:–3.96 – 2.84 = –6.8
</span></span><span><span>B) You can always change the order of positive and negative decimals when adding and you’ll get the same answer. When you change the order of positive and negative decimals when subtracting, you will get opposite answers.
C) Sally’s statement is true for addition of three positive and negative decimals but not true for subtraction. The equations students write to support their answers will vary. Sample pairs of equations that support the answer that Sally’s statement is true for addition but not subtraction are as follows:
Sample addition equation:
–6.2 + 5.71 + (–3.96) = –4.45Sample subtraction equation:2.84 – (–3.96) – (–6.2) = 13</span></span>

Answer:
i think this is the answer Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2).
