Answer:

25. Not a solution

26. Yes a solution

27. y= 2/3 x

28. y=3x+16

Step-by-step explanation:

25. The solution to a linear equation is the point (x,y). To find if an (x,y) is a solution, substitute it into the equation and see if it works.

y=4x-4 and (8,3)

3=4(8)-4

3=32-4

3=28

False

Not a solution.

26. Repeat 25 to solve 26 with y=5x-5 and (0,-5)

y=5x-5 and (0,-5)

-5=5(0)-5

-5=0-5

-5=-5

True

Yes a solution.

27. This line crosses through the origin is proportional and therefore has the form y=mx. It also has a gentle slant meaning that is less than 1/2 and goes in a positive direction. This means it is y=2/3 x.

28. Use inverse operations to rearrange the equation.

y-3x=16

y=16+3x

y=3x+16

What is the area of a triangle with a base of 4v^3 and a height of vu^2?
IgorLugansk [536]
Answer:  The area of the triangle is:     " 2v⁴u² square units" ;
                                            or, write as:  " 2v⁴u² units² " .
______________________________________________________
<u>Note</u>:  The formula/equation for the area, "A", of a triangle is:

             A = (1/2) * b * h  ;   or:  A = (b * h) / 2 ; 
______________________________________________________
  in which:   "A" = "area" ; 
                   "b" = "base length" ;
                   "h" = "[perpendicular] height" ; 
______________________________________________________
We are asked to solve for the area, "A" .

We are given:  "b = 4v³ " ;  "h = vu² " ;

So;  to find the area, "A", of the triangle, we plug these given values into the formula; and solve/ simplify:
____________________________________________________
     A = (1/2) * b * h ; 

     A = (1/2) * (4v³) * (vu²) ; 

     A = 2v³ * vu² ;

     A = 2v⁴u²  square units.

Answer:  The area of the triangle is:     " 2v⁴u² square units" ;
                                            or, write as:  " 2v⁴u² units² " .
