Answer: x=14
Explanation: the angle needs to equal the other angle, which is 63. To figure this out, we subtract 21 from 63. We get 42. 42 divided by 3 is 14. We are basically doing the equation in reverse.
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Vertical compression
Answer:
∴ x= 17
Step-by-step explanation:
the total of angel in 90°
∴ 2x+3+3x+2 =90
∴ 5x +5 =90
5x=90-5
5x = 85 (divide both side by 5)
∴ x= 17
Answer:
negative correlation
Step-by-step explanation:
If you were to draw a line of best fit (a line that best expresses the relationship between a group of points), it would have a negative slope.
Answer:
(2x^2+7)
Step-by-step explanation:
5x^3 * 2x^2 = 10x^5
5x^3 * 7 = 35x^3
