Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1
Answer:
Step-by-step explanation:
Question: 
1) Add 10 to both sides:
2) Multiply both sides by the reciprocal of 2/3: (3/2)
3) Simplify the fraction:
Answer:
1 yard
Step-by-step explanation:
1yard = 3 feet and there is only 2
Answer:
1. 20 cm^2
2. 40 cm^2
3. 14 cm^2
4 49 cm^2
Step-by-step explanation:
Area of triangle= 1/2(base)*(height)
Area of rectangle= (base)*(height)
1. 1/2(10)(4)=20
2. (8)(5)=40
3.1/2(4)(7)=14
4. (7)(7)=49
