Answer:
The solution of the system is at point (1,6) and (7,0).
Step-by-step explanation:
Given : System of equation and
To find : Solve the system of equation?
Solution :
We solve the equation graphically as the intersection points give you the solution of the system.
The equation given is one linear and one parabolic.
(1) is a linear equation in red line passes through (0,7) and (7,0).
(2) is a parabolic equation in blue line passes through (-1,0) and (7,0)
The intersection point of the equations are (1,6) and (7,0).
<u>Refer the attached figure below.</u>
Therefore, The solution of the system is at point (1,6) and (7,0).
Answer:
3. C or 18.
4. Perimeter: 10 Area: 6.25
5. 3 and 16
Step-by-step explanation:
3. Because the area of a triangle is 1/2 the base times the height if you double the area you can divide this total area by one side to find the length of the other side. In this problem that is 72*2 which is 144. Then dividing 144/8 you get 18, which is answer choice C.
4. Since a square has 4 sides that are all the same, you only need to know one side length to know them all. Multiplying one side length (2.5) by itself will get you the are of the square as a whole. Doing this (2.5 multiplied by 2.5 gets the area of 6.25.
For the perimeter calculation use the formula for a perimeter of a square which is one side (2.5) multiplied by 4 is 10, which is the perimeter.
5. This is because 3*16 is 48 or the area of the rectangle.
Remark
It is very handy to remember that a line is always equal to itself. In this case, LN = LN will come in very handy.
Givens
LM = PL Given
MN = NP Given
LN = LN Reflexive property. A line is always equal to itself.
These three sides are congruent in one triangle as they are in the second triangle. The triangles are congruent by SSS
Answer:
2xy - 6x +2y
Step-by-step explanation:
12xy - 10xy = 2xy
5y - 3y = 2y
2xy - 6x + 2y
Answer:It
It can be 12, 13, 14 and more up
Step-by-step explanation:
Is that because 12+7= 19 which is bigger than 18
