Given the equation y=-2x+4, we can easily find the slope of the perpendicular line by calculating the inverse negative of the slope. This is:
Now that we have the slope, we can ouse the equation slope-intercept to find the intercept b using the point (-3,-2):
Therefore, the equation in slope-intercept form is:
Answer:
I think it's all of them :)
Answer:
Option D. 37¼ ft
Step-by-step explanation:
The perimeter of the figure above can be obtained by adding all the lengths of each sides together. This can be obtained as follow:
The lengths of each sides are given below:
Top = 6¼ ft
Left = 9⅛ ft
Bottom = 9½ ft
Right = 7¾ ft
Top horizontal = 9½ – 6¼
= 19/2 – 25/4
= 13/4 ft
Top height = 9⅛ – 7¾
= 73/8 – 31/4
= 11/8 ft
Perimeter = 6¼ + 9⅛ + 9½ + 7¾ + 13/4 + 11/8
= 25/4 + 73/8 + 19/2 + 31/4 + 13/4 + 11/8
= 149/4
= 37¼ ft
Thus, the perimeter of figure is 37¼ ft
3/4÷ 2/3= 3/4*3/2= 9/8= mixed fraction 1 1/8 pounds.
Three teachers are needed for 70 children, that is:
3 = 70.............. equation 1.
For 14,700 children, Y number of teachers are needed, thus, we have
Y = 14,700...........equation 2.
3 = 70
Y = 14, 700.
Cross multiplying we give us,
3 * 14, 700/70 * Y.
44,100/70Y
Y = 630.
Thus, 630 teachers are needed to teach 14,700 children.
The district already have 612 teachers, so they need 630 - 612 = 18.
So, the district needs 18 more teachers.
