Answer:
9) slope of AC = slope of FH
Equation of the line is y = - x + 5
10) Area = 320
Step-by-step explanation:
For 9, the only thing similar IS the slope of the hypotenuse because the triangles are along the same line. Unless they're asking for the equation of the line, then that's just using the point slope equation which is:
y = - x + 5
For 10, just multiply 4 and 5 by 4 to get 16 and 20. Then multiply 16 and 20 to get 320.
start with distributive property
5 - 6 + 2x = 4x + 10
Combine like terms:
-1 + 2x = 4x + 10
move the 2x over by subtraction
-1 = 2x + 10
move the 10 over by subtraction
-11 = 2x
divide by 2
x = -11/2
Answer: Down
If on the other hand a > 0, then the parabola would open upward.
Answer:
10^5 = 100.000
Step-by-step explanation:
We know that 10^5 = 10 * 10* 10 * 10 * 10 = 100.000.
So, we have that 10^5 = 100.000
