Answer:
C)
Step-by-step explanation:
Note that one of the lines is simply y=-1 for any x, so we can dismiss the only answer without y=-1. That rejected answer is A)
Now let's notice, that the other line is decreasing y when increasing x. That tells us that in the equation y = ax + b, a has to be negative. This brings us to reject option D).
What is the y of that line for x = 0? Because y = ax + b, for x = 0 we will get the value of b. This is called the intercept. The line is at y=4 for x=0, so we know that the b in the equation must be positive 4. This fits answer C, but rejects answer B). And so, we have found that C) is the only possible answer.
B, the first differences are not the same , that proves it is not linear. The second set of differences are the same this shows it is a quadratic function.
Answer:
x = 8 is the answer :)
Step-by-step explanation:
Slope(m) = -2/5
slope is passing through the points: (x,1) and (3,3)
-2(3 - x) = 2 × 5
-6 + 2x = 10
2x = 10 + 6
2x = 16
x = 8
Hopefully, this answer helped :)
Answer:
AC = 12 units.
Step-by-step explanation:
Δ ACD is right-angled. ( as CD ⊥ AB).
cos 45° = CD / AC = 6√2 / AC
AC = 6√2 / cos 45°
AC = 6√2 / 1 /√2
= 6√2 *√2
= 6 * 2
= 12 (answer)
