Answer:

It is a rectangle.

LENGTH = 5 X+2   IF X = 5        L = 5×5+2 =25+2=27

L=27

BREADTH = X+8 IF X=5     B =5+8= 13

B= 13

Area of the rectangle = L× B

                                       =27×13

                                    = 351

Perimeter of the rectangle=2(l+b)

                                        =2(27+13)

                                     =2×40

                                    =80

Solve the linear equation.<br> 7x+10= 1/3(12x-3)+14x
pychu [463]
7x+10=1/3×(12x-3)+14x

7x+10=1/3×3(4x-1)+14x

7x+10=(4x-1)+14x

7x+10=4x-1+14x

7x+10=18x-1

7x-18x=-1-10

-11x=-11

x=1

If the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola, find an equation for the parabola. Write
STALIN [3.7K]

Answer:

y=-1(x-2)^2+3

Step-by-step explanation:

W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form y=(x-h)^2+k.  

We know that vertex form of parabola in form y=a(x-h)^2+k, where (h,k) in vertex of parabola.  

Upon substituting coordinates of vertex, we will get:

y=a(x-2)^2+3

To find the value of a, we will substitute coordinates of point (0, -1) as:

-1=a(0-2)^2+3

-1=a(4)+3

-1=4a+3

-1-3=4a+3-3

-4=4a

\frac{-4}{4}=\frac{4a}{4}

-1=a

Therefore, our required equation would be y=-1(x-2)^2+3.
