Answer:

f(0)=2

Given the function f(x)=-x+2, to find f(0), simply substitute x=0 into the function.

Solving, we get:

f(0)=-(0)+2=\boxed{2}

Step-by-step explanation:

\sqrt{3}  \times  \sqrt{3}  = 3 \:  \: (rationalize)

\sqrt{3}  \times ( -  \sqrt{3} ) =  - 3

The rationalizing factor of \sqrt{ 3}

is \boxed{\green{\sqrt{3}  \:  \: or \:  \:  -  \sqrt{3}}}

Can someone please help me please !
TEA [102]

Answer:

Step-by-step explanation:

GH : √(8-4)^2 + (2-5)^2 = √16+9 = √25 = 5

HI : √(-6-2)^2 + (2-8)^2 = √64+36 = √100 = 10

IJ : √(-2-2)^2 + (-3+6)^2 = √16 + 9 = √25 = 5

JH : √(-2-4)^2 + (-3-5)^2 = √36 + 64 = √100 = 10

Slope of the line that contains GH

(2-5)/(8-4) = -3/4

Slope of the line that contains HI

(-6-2) / (2-8) = 8/6 = 4/3

I calculated the distance between points. Thanks to that I noticed that the opposite sides are congruent, so the quadrilateral can be a rectangle or a parallelogram. So I found the slope of the lines that contain two consecutive sides and I discovered that are perpendicular. So the quadrilateral is a rectangle because its angles are all of 90 degrees

A line has a slope of -3 and includes the point (-5,4) and (-7,q). What is the value of q​
serious [3.7K]

Answer:

q = 10

Step-by-step explanation:

\text{slope} =-3=\frac{q-4}{-7-(-5)} =\frac{q-4}{-2} \\\Longrightarrow -3=\frac{q-4}{-2} \\\Longrightarrow \left( -3\right)  \times \left( -2\right)  =q-4\\\Longrightarrow 6=q-4\\\Longrightarrow q=6+4\\\Longrightarrow q=10
