C is false. 9 multiplied by 7 equals 63.
Answer:
y intercept equals 1
Step-by-step explanation:
y= -1/2x+1
the slope is -1/2
the y intercept is 1
Answer:
Tan B = 12/5
Sin B = 12/13
Cos B = 5/13
Step-by-step explanation:
sine B = opposite (12)/hypotenuse (13)
= 12/13
Cosine B = adjacent/hypotenuse
= 5/13
Tangent B = opposite/adjacent
= 12/5
Here is a picture that can always help you with the three trig ratios.
Answer:
the x is the independent variable so the guests the y is the dependent variable so the cost.
Step-by-step explanation:
because so when there are 100 people there is 4,200 +750 and the cost is 4,950
Answer:
y = - 5/2x + 24
Step-by-step explanation:
2x - 5y = - 12. (10, -1)
- 5y = - 2x - 12
y = -2/-5x -12/-5
y = 2/5x + 12/5
Slope: 2/5 (slope of the perpendicular line: - 5/2)
y - - 1) = - 5/2(x - 10)
y + 1 = - 5/2x + 25
y = - 5/2x + 24
