Graph h(x)=0.5(x+2)^2 -4 by following these steps:
Goshia [24]

Answer:

Step 1: Identify a, h, and k.

a=0.5, h= -2, k= -4

Step 3: The axis of symmetry is the line x= -2

Step 4: h(-4)= -2 h(-6)= 4

The graph should have points plotted at (-6, 4), (-4, -2), (-2, -4), (0, -2), and (2, 4)

Step-by-step explanation: The answers were already there, just here to repeat for others who are confused.

Special right triangles, find x and y
egoroff_w [7]

Answer:

The answer to your question is x = 17.32; y = 8.67

Step-by-step explanation:

Process

1.- Use trigonometric functions to find x and y

   a) sin Ф = \frac{opposite side}{hypotenuse}

      Ф = 60°

      opposite side = 15

      hypotenuse = ?

     hypotenuse = \frac{opposite side}{sin \alpha }

     hypotenuse = \frac{15}{sin 60}

     hypotenuse = \frac{15}{0.87}

            hypotenuse = 17.32

     b) cosФ = \frac{y}{hypotenuse}

         y = hypotenuse x cos 60

         y = 17.32 x 0.5

                y = 8.67

vova2212 [387]

Answer:

y=-2x+11

Step-by-step explanation:

equation of a line

y-b=m(x-a)

m=-2

a=3

b=5

sub into the equation

y-5= -2(x-3) multiply out the brackets and a negative multiply by negative equals positive

y-5=-2x+6

y=-2x+11

or

2x+y-11=0

Solve the system equation
den301095 [7]
<h2>Answer:</h2>

We will use substitution to solve this system for x.

x - 2y = 27\\y = 5x\\\\x - 2(5x) = 27\\\\x - 10x = 27\\\\-9x = 27\\\\x = -3

Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.

-3 - 2y = 27\\\\-2y = 30\\\\y = -15\\

We now have our solution.

D. (-3, -15)

We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.

-3 - 2(-15) = 27\\\\-3 + 30 = 27\\\\27 = 27

Since the equation checks out, our solution is correct.

2 divided by -12 what is the answer?
Strike441 [17]

Answer:

-1/6

Step-by-step explanation:

When dividing 2 by -12 you would use 2 as the numerator and -12 as the denominator and then simplify it by dividing both by two to end up with -1/6
