Answer:
its commutative property. you just switch the letters and they will still have the same value
Step-by-step explanation:
We have two coordinates here: (2, 225) & (5, 480)
Now, Calculate for the Slope:
m = y2-y1 / x2-x1
m = 480-225 / 5-2
m = 255/3
m = 85
y - y1 = m(x - x1)
y - 225 = 85(x - 2)
y - 225 = 85x - 170
y = 85x + 55
8x - y = -55 [ Final Equation in the standard form ]
B.) F(x) = 85x + 55
C.) For x=1, F(x) = 85(1) + 55 = 140
For x = 2, F(x) = 85(2) + 55 = 225
For x = 3, F(x) = 85(3) + 55 = 310
In short, Your Coordinates for the Graph would be: (1, 140) (2, 225), (3, 310)...
Hope this helps!
If the temp is 12f and changes by -26f
Is 38f
Answer:
43
Step-by-step explanation:
This is an example of difference of two squares, because 49 is a squared number. Thus, you can write it in the form, (a + b)(a - b).
Thus, [(x - 3) + 7][(x - 3) - 7] = 0
(x + 4)(x - 10) = 0
And the zeros are at: x = -4, 10
