So, I'd say you are correct.
Answer:
The answer is A
Step-by-step explanation:
By looking at the graph, the y-intercept is -1. So, the answer must be A or C.
Then we can look at the the graph, you can see the line is left up right down. So the equation will be negative, which is A.
Answer:
- 439
Step-by-step explanation:
- s ( x ) = 2 - x²
- t ( x ) = 3x
- s ( t ( -7 ) ) = ?
--------------------------
- t (-7) = 3 * ( -7 ) = -21
- s ( t ( -7 ) ) = s ( -21 ) = 2 - ( -21 )² = 2 - 441 = - 439
- s ( t ( -7 ) ) = -439
Hello :
<span>y = –2x – 1....(1)
y = 3x–1.....(2)
by (1) and (2) : 3x-1 = -2x-1
5x =0
x =0 ....(</span><span>the x-coordinates of the solutions)</span>
