If you are trying to write this as an equation I believe it goes like this:
3x-6=9
We don’t know the number that is multiplied by 3 so we just use x.
If you solve for x, it’s 5.
3(5)-6=9
15-6=9

Step-by-step explanation:
The sine of an angle is equal to the cosine of that angle minus 90 degrees, and vice versa. Since 65=90-25, the cosine of 25 is equal to the sin of 65. If this is unclear please PM me or comment, and I can help more!
Answer:
The 2nd one
Step-by-step explanation:
It is a compression, because you are multiplying by a whole number greater than 1, therefor the line will look thinner
For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.
