What would the vaule of y be when x=-2

Mathematics

Bond [772]3 years ago

Answer:

Step-by-step explanation:

Formula for direct variation is y=kx, where k represents the constant. So, we solve for "k" first given the "x" and "y" variables.

 

Read "y varies directly as x" when y=2, x=10:

 

2 = k(10)

 

2  = k(10)

10      10

 

1

5  = k  

 

Now that you found "k" you can substitute that into equation with the other given variables:

y = (1/5)(-25)= -5

The function. In the graph is f(x) =
Tanya [424]

Answer:

x^3-2x^2-5x+6

Step-by-step explanation:

We have been given a graph of the function f(x).

Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:

x^4-2x^2+5x+6

x^3-2x^2-5x+6

x^3-2x^2+5x+6

-x^4-2x^2+5x+6

We see that graph has end points in opposite direction then the degree of polynomial must be ODD.

Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.

Only x^3-2x^2-5x+6 satisfies the given points from graph.

Hence correct choice is x^3-2x^2-5x+6.

Y is directly proportional to X^2<br> If y = 45 when x = 3 find<br> y when x = 5
postnew [5]

Answer:

Y = 125

Step-by-step explanation:

Y is directly proportional to X^2

Mathematically,

Y ∝ X²

Y = kX²

Where k = Constant of Proportionality

Step 1

If y = 45 when x = 3

We solve for k

Y = kX²

k = Y/X²

k = 45/3²

k = 45/9

k = 5

Step 2

find y when x = 5

Y = kX²

k = 5, X = 5

Hence,

Y = 5 × 5²

Y = 125

Find the value of y 74 77 89 96
Morgarella [4.7K]
The external angle (53°) is half the difference of the intercepted arcs (y°, 180°), so we have
  53 = (180 - y)/2
  106 = 180 - y
  y = 180 - 106
  y = 74

The appropriate choice for the value of y is ...
  74
