Answer:

y=[-2]x[+][5]

Step-by-step explanation:

$\frac{-1-3}{3-1}=\frac{-4}{2} =-2$ m= -2

Using the point (1,3) Find the value of b

3= -2(1)+b

3= -2+b

+2 +2

---------

5=b

2. Find the length of a side of a square if its area is:

Anna007 [38]

Answer:

9 inches ; 0.7 units ; m units

Step-by-step explanation:

The area of a square is give as :

The square of the side length of the square ; that is ;

Area of square = s² ;

Where s =! Side length of the square

Hence ;

A square with area = 81 in²

Length of its side = sqrt(81) = 9 inches

Area of square = 0.49 unit²

Length of its side = sqrt(0.49) = 0.7 units

Area of square = m² unit²

Length of its side = sqrt(m²) = m units

F(x)=x^2-3x+7 and g(x)=x+3 solve f(x)=g(x)

grandymaker [24]

For this case we have the following functions:

$f (x) = x ^ 2-3x + 7\\g (x) = x + 3$

Equalizing we have:

$x ^ 2-3x + 7 = x + 3\\x ^ 2-3x-x + 7-3 = 0\\x ^ 2-4x + 4 = 0$

To solve we factorize, that is, we look for two numbers that when multiplied give a result of 4 and when added together give a result of -4. These numbers are -2 and -2.

$-2-2 = -4\\(-2) * (- 2) = 4$

Thus, we have:

$(x-2) (x-2) = 0\\(x-2) ^ 2 = 0$

So, the solution is $x = 2$

Answer:

$x=2$
