<h2>Answer with explanation:</h2>

<u>Part--1:</u>

We know that a equation in point-slope form is represented by:

               y-y_1=m(x-x_1)

where m is the slope of the line and (x_,y_1) is a point through which the line passes.  

  Consider a equation in a point-slope form as:

           y-5=2(x-1)

This means that the slope of the line is: 5

and the line  passes through the point (1,5).

<u>Part--2:</u>

Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m

Since,

m\times \text{Slope\ of\ second\ line}=-1\\\\i.e.\\\\\text{Slope\ of\ second\ line}=\dfrac{-1}{m}

Let this perpendicular line passes through (2,6)

Hence, the equation of a line in point slope form is given by:

             y-6=\dfrac{-1}{2}(x-2)

Answer:

\dfrac{18}{5}

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

\dfrac{18}{5}

What is the value of f(7)<br> y=f(x)
Murljashka [212]

Answer:

f(7) = 6

Step-by-step explanation:

f(7) is the y coordinate of the point on the given graph of y = f(x), whose x coordinate is 7.

From the graph of y = f(x), we see that f(7) = 6.
