Y = x
when x < -1
not equal to (≤) so no solid circle.
plot points
x | y
-1, -1
-2, -2
-3, -3
Next one is...
y = -x
when x ≥ -1
solid circle for equal to
look at points
x | y
-1, 1
0, 0
1, -1
2, -2
As you can see it's the last graph in bottom right corner.
Step-by-step explanation:
1. if to evaluate the given experssion, then
7⁶(7²-7+1)=7⁶*43.
2. if to divide this evaluated expression by 43, then
7⁶*43/43=7⁶.
Answer:
2B / (mx) = y
Step-by-step explanation:
B = 1/2 mxy
Multiply each side by 2
2B = 2* 1/2 mxy
2B = mxy
Divide each side by mx
2B / (mx) = mxy / (mx)
2B / (mx) = y
Answer:
51 = A
Step-by-step explanation:
Using the law of sines
sin 95 sin A
------------- = -----------
9 7
Using cross products
7 sin 95 = 9 sin A
Divide each side by 9
7/9 sin 95 = sin A
Take the inverse sin of each side
sin ^-1 ( 7/9 sin 95) = A
50.78854367= A
To the nearest degree
51 = A
