Hello from MrBillDoesMath!
Answer:
Suppose the ordered pair is (x.y). Substitute these values in the linear equality to see if it is true,
Example. Consider the point (7, -4). Is it a solution of the linear inequality
3x < 4y - 9? Let's check to find out.
Check:
Is 3 (7) < 4 (-4) - 9 true ?
Is 21 < -16 -9 = -25 ??
NO!
So (7,-4) is NOT a solution of the linear inequality.
Thank you,
MrB
The answer is 223.75 because you multiply 12.5 and 17.9
Answer: The area is 530 square units
Step-by-step explanation: The diameter of the circle has been given as 26. That makes the radius 13, that is;
Radius = diameter/2
Radius = 26/2
Radius = 13
The area of a circle is derived by the formula;
Area = pi x r^2
Where pi is 3.14 and r is 13,
Area = (3.14) x 13^2
Area = 3.14 x 169
Area = 530.66
Approximately to the nearest hundred of a square unit,
The area of the circle is 530 square units
Answer:
A.
Step-by-step explanation:
Answer:
y = -1/3x + 8
Step-by-step explanation:
If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.
(basically if one is say -2/3, the other is 3/2. just flip it upside down)
So this slope is 3, so the new slope should be -1/3
The equation is now y = -1/3x + b
To find b, substitute (-9,5) in the equation
y = -1/3x + b
5 = -1/3(9) + b
5 = -3 + b
8 = b
So the equation is y = -1/3x + b
