Answer:
3/1, or 3
Step-by-step explanation:
When you have a perpendicular line, if it is a negative, you take away the negative, and if it is a fraction, you turn it upside down. 1/3 becomes 3/1.
We are given with the mathematical expression <span>sinx=cos(48) and is asked in the porblem to determine the value of variable x. In this case, we solve first cos 48 which is equal to -0.64. to determine x, we use inverse sin, that is sin-1 (-0.64) = x; x= 42 degrees. x is equal also to 90-48 according to complementary postulate.</span>
Answer:
2(x^2)-1
Step-by-step explanation:
The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.
Hope this helps! :D

The equation to find the slope of a line is "y2 - y1 / x2 - x1"
Our second y coordinate is 5 and our first y coordinate is 2.
5 - 2 = 3.
Our second x coordinate is -7, and our first x coordinate is 12.
-7 - 12 = -19.
We now have 3 / -19
3 / -19 = ~-0.158
Therefore, the slope of the line is ~-0.158
