I think the answer is 16.8
Answer:
y=mx+b
so, y=1/4x+6
Step-by-step explanation:
plug in, then simplify the slope.
Answer:

Step-by-step explanation:
For each right-angled triangle:

Because 
we have an equation

multiplying both sides by x, we get 
dividing both sides by 0.4 and 
using calculator, we divide 12 by 0.4
and finally x=30
Answer:
x ≤ 2
Step-by-step explanation:
If you referencing ">=" as greater than or equal to, follow the solution below:
Solve:
3x - 6 + 2 ≥ 5x - 8
Combine like terms.
3x - 4 ≥ 5x - 8
Subtract 5x from both sides.
-2x - 4 ≥ -8
Add 4 to both sides.
-2x ≥ -4
Divide both sides by -2, while flipping the inequality as well since you're dividing by a negative number.
x ≤ 2
Your answer would be x ≤ 2
For the first one we see that the shape is that of a parabola and is translated down a few units, We can eliminate linear, exponential
and looking at the general shapes of quadratic and polynomial functions we can conclude that the graph is from a quadratic equation
So Answer is: (2) quadratic
I hope that helps
