Answer:
h(g(x))=h(3x^2+1)=2(3x^2+1)=6x^2+2
Answer:
(2,3)
Step-by-step explanation:
I did this by using the equation that was given. y=x+1.
This mean that the starting point would be the coordinate (0,1) and the x is the slope, which means that from coordinate (0,1) I will go up one and one to the right until I intersected with coordinate (2,3).
Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19
