Answer:
A. The graph of the function increases and decreases over its domain.
Step-by-step explanation:
The graph is attached. Some places, it has positive slope (is increasing); other places it has negative slope (is decreasing).
D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.
Answer: the answer is -2 1/3
Step-by-step explanation: it would be -2 1/3 because 5 + 2=7 and then add the 1/3 to make -7 1/3
<span>y = -3.5x - 3.5
y = -3.5x 3.5
I do not see a sign for the constant term (y-intercept) in the second equation.
In any case, since the equation reads y=-3.5x + (y-intercept) in both cases, the lines are parallel to each other.
If the y-intercepts are identical, then the equations are also identical, therefore there are infinitely many solutions.
If the y-intercepts are different (e.g. +3.5 and -3.5), then the two equations form distinct (i.e. not coincident) parallel lines, and therefore has solution.
So it depends on the missing sign, and you will be able to judge when the sign is given.</span>
Answer to the first question is A. X = 10 and y = -2. Plug it into the equation.
-2 + 2 = 3/5(10 - 10)
0 = 0
Answer to the second question is A. It is going up "rise" by 4. And left "run" by -5
Answer to the third question is A. 2x will represent the slope. 5 will represent the y intercept.
Answer to the fourth question is C.
Answer to the last question is B. y = 5(1) y = 5. y = 5(0) y = 0.
Hope that helps
