Step-by-step explanation:

it goes up by 2 each time for x and adds 4 for the y

you do y/x to find the constant of proportionality.

y = 4 and x = 2

4/2 = 2

answer = B

The height of a triangle is 8 centimeters greater than half its base. The area of the triangle is 48 square centimeters what is
emmainna [20.7K]

Answer:

base = 8 cm

height = 12 cm

Step-by-step explanation:

We will need the formula for area of a trianlge, which is

A = (1/2)bh    where b is the base, and h is the height

We are given two formulas...

"The height of a triangle is 8 centimeters greater than half its base" becomes

  h = (1/2)b + 8

"The area of the triangle is 48 square centimeters" becomes

48 = (1/2)bh

Plug the first formula into the second to solve for h

48 = (1/2)b[(1/2) + 8]             (h becomes (1/2)b + 8)

Now solve for b

48 = (1/4)b² + 4b

**This is a quadratic euquation.  Solve using factoring...

(1/4)b² + 4b - 48 = 0       (subtract 48 from both sides)

b² + 16b - 192  =  0       (multiply by 4 so b² is by itself, it's easier to factor this way)

Now factor...

(b + 24)(b - 8) = 0       (you need two numbers that add to 16 and multiply to -192)

Set each binomial equal to zero and solve for b

b + 24 = 0          

    b = -24    

**this anwser is not valid because b is a length, and you can't have negative length

b - 8 = 0

  b = 8        

Since the other solution is invalid, the base is b

If the base is b, then the height is...

h = (1/2)b + 8

 

   h = (1/2)(8) + 8

     h = 4 + 8

 

         h = 12

16 question Write a rule for the linear function in the table
Ira Lisetskai [31]
To write the rule or equation of the linear function we need to find the slope of the function first. Using any two points we can find the slope.

Using the first two points (-3, -1) and (0, 2).

Slope (m) of the function would be:

m= \frac{-1-2}{-3-0}= \frac{-3}{-3} =1

Using slope and the point (0,2) we can write the equation of the line as:

y - 2 = 1(x-0)
y = x + 2

Thus, the correct rule for the given linear function is x+2
