Answer:
y=3
Step-by-step explanation:
Answer:+3i or -3i
Step-by-step explanation:
±√(-36)=+√(-36) or -√(-36)
+√(-1)×√(36) or -√(-1)×√(36) √(-1)=i
+i×6 or -i×6=+6i or -6i
Dividing by 2 we get
+6i/2 or -6i/2=+3i or -3i
Answer:
1) x≥6
--------------------------------------
--------------------------------------
2) h > 20
Mark worked more than 20 hours.
Step-by-step explanation:
1) -20x+18≥-102
-20x≥-102-18
-20x≥-120
Dividing -20 both side
≥
x≥6
--------------------------------------
--------------------------------------
2) 14h + 25 > 305
14h > 305-25
14h > 280
Dividing 14 both side

h > 20
Mark worked more than 20 hours.
Answer:
slope = -2
Step-by-step explanation:
To find the slope, you can use the slope formula,
.
and
represent the x and y values of one point the line passes through, and
and
represent the x and y values of another point the line also passes through.
So, in order to answer the question, we need two points from the line. To find these points, look at the x and y values of the table - they form points. Thus, (-2, 0) and (-1,-2) would be two points the line passes through. Use those x and y values and substitute them into the formula. Then, solve:

Thus, the slope is -2.
