Answer:
-9
Step-by-step explanation:
-30 + 16 is -14 then -14 - 7 is -21 then -21 +3 is -18 then -18 + 9 is -9
<h3><u>The function used to find the perimeter of a square, represented by y, given the length of a side, represented by x is: y = 4x</u></h3>
<em><u>Solution:</u></em>
Let "y" be the perimeter of square
Let the length of side be "x"
From given,
The perimeter of a square is the product of four and the length of a side
Which means,
Substituting the given variables,
Thus perimeter of square is y = 4x
The equation which can be used to find the length of EF is option A which is EF=.
Given the length of base of right angled triangle is 12 and the hypotenuse be 24.
We are to find the length of EF and tell which equation can be used to find the length of EF.
We know that pythagoras theorem applies in a right angled triangle.
Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.
In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.
EF=
=--1
=
=
Hence the equation which can be used to find the length of Ef is option A which is EF=.
Question is incomplete as it should include the figure also.

Answer:
(1,5) is not a solution to the system of equations
Step-by-step explanation:
To find the point (1, 5) is a solution to the system of equations.
We look at the intersection of both graphs given
Both graphs intersects at (0,2)
Intersection of two graphs is the solution of system of equations
Two graphs intersects at (0,2). so (0,2) is the solution of system of equations
(1,5) is not a solution to the system of equations
