Answer:

  x = 40 1/2

Step-by-step explanation:

The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the  larger one. Then x is half the length of the corresponding segment marked 81.

  x = 81/2

  x = 40 1/2

___

You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.

Answer:

y=\cfrac{1}{2}\;x-4

x   |  y

10    1    = 1/2 (10) -4=5-5= 1

-2    -5  = 1/2(-2)-4=-1-4= -5

4     -2   = 1/2(4)-4=2-4= -2

-8    -8  = 1/2(-8)-4=-4-4= -8

The first step in determining the solution to the system of equations, y = -x2 - 4x - 3 and y = 2x + 5, algebraically is to set
sweet-ann [11.9K]

Answer:

Combine like terms onto one side of the equation

Step-by-step explanation:

You have

-x^2  -4x  - 3  = 2x + 5

It seems that we should combine like terms to make this equations smaller.

-x^2 - 4x - 3  - 2x  - 5 = 0

-x^2  -6x  - 8 = 0

- (x + 2)(x + 4) = 0

x = -2  or  x  = -4

This equation is telling you to subtract the value of f(x) from the value of g(x).


f(x)= x + 2
g(x) = 3x + 5

so x + 2 - 3x -5 = -2x-3
