Answer:
The answer to your question is because it is a solution of each equation.
Step-by-step explanation:
Data
Point (3,4)
Equation l y = 1/3x + 3
Equation ll y = 2x - 2
Process
1.- To test is a point is solution to a system of equations,
-Substitute the point in both equations
Equation l 4 = 1/3(3) + 3
4 = 1 + 3
4 = 4 The point is a solution because
4 = 4
Equation ll 4 = 2(3) - 2
4 = 6 - 2
4 = 4 This point is a solution for the second
equation but not for the first one.
2.- Conclusion
As the point is a solution of each equation, it is a solution of the system.
Answer:
(2v +7)(v -9)
Step-by-step explanation:
Factors of 2·(-63) = -126 that have a sum of -11 are 7 and -18, so we can rewrite the middle term to -18v+7v. Then we can factor by grouping.
2v^2 -18v +7v -63 = 2v(v -9) +7(v -9)
= (2v +7)(v -9)
Answer:
453.75 sq. feet
Step-by-step explanation:
In this question, we are going to calculate the area of a room given the blue print measurement and the actual measurements with the answer being in the actual measurement.
To correctly do this, it is best if the measurements are converted to the actual.
The measurements we’ll be trying to convert is 5 inches by 3 inches with a scale of 2in to 11ft ( same as 1 in to 5.5 ft)
The 5 inches blueprint measurement will be 5 * 5.5 = 27.5 ft
The 3 inches blueprint measurement will be 3 * 5.5 = 16.5 ft
The area in sq. feet will be length * width = 27.5 * 16.5 = 453.75 sq feet
Answer:
degree of the polynomial is highest power of x in P(x) .
So degree is 5.
Because you know the area and that the shape is a square... if the side length is "s"... to find "s" you would say...
s²=1.69
Take the root of both sides and...
s=1.3 km
