Answer:

slope = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + y = 3 ( subtract x from both sides )

y = - x + 3 ← in slope- intercept form

with slope m = - 1

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-1}$ = 1

Factor the polynomial expression 4x2 +9.

Yanka [14]

Answer:

Step-by-step explanation:

Factor it by first setting it equal to 0:

$4x^2+9=0$ Now subtract 9 from both sides:

$4x^2=-9$ Divide both sides by 4:

$x^2=-\frac{9}{4}$ Then take the square root of both sides:

x = ± $\sqrt{-\frac{9}{4} }$ , which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,

x = ± $\sqrt{-1*\frac{9}{4} }$ is an equivalent radicand, we can now replace -1 with its imaginary counterpart:

x = ± $\sqrt{i^2*\frac{9}{4} }$

Each one of the elements in the radicand are perfect squares, so we simplify as follows:

x = ± $\frac{3}{2}i$

And there you go!

Evaluate.

madreJ [45]

Answer:

Answer is none of these.

Answer is given below with explanations. 

Step-by-step explanation:

Given that x = -2.5

To find the value of x+13

Ob substituting the value in the given equation 

we get 

= -2.5+13

= 13 - 2.5 (we can also write like this)

= 10.5

Therefore value of x +13 is 10.5
