Answer:
(-2, -6)
Step-by-step explanation:
Slope: 1
1. Write the equation:
d(-3 + x) = kx + 9
2. "Open" the parenthesizes:
-3d + dx = kx + 9
3. Take kx to the left side, -3d to the right, everything with different sign (+ replace with - when transferring, - replace with +):
dx - kx = 9 + 3d
4. Factor x in the left side:
x(d - k) = 9 + 3d
5. Finally, divide the whole equation by (d - k):
x = (9 + 3d)/(d - k)
That's the final answer. Good luck!
Hi there!
The formula for the area of a triangle is A = 1/2(b x h). Using the information provided, all we have to do is plug in what we know and solve!
WORK:
74 = 1/2(b x 9.14)
148 = b x 9.14
b = 16.2 inches (approximately)
Hope this helps!! :)
Answer:
-7 degrees
Step-by-step explanation:
The temperature is predicted to be ...
5 +3(-4) = 5 -12 = -7 . . . . degrees
__
To find the change, multiply the rate of change by the time period. To find the new temperature, add the change to the starting temperature.
Answer: 
Step-by-step explanation:
Given
Vertex of the parabola 
Focus of the parabola 
As the x coordinate of vertex and focus is same and focus lie below the vertex, therefore the parabola is the type of
distance between Vertex and focus is 1 unit
Parabola becomes
