Write a system of linear equations for the graph below.​
sp2606 [1]
<h2>Answer:</h2>

We need to determine the equation of both lines first.

  • Line 1: <em>y = -2x + 3</em>
  • Line 2: <em>y = -1/3x - 2</em>

Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.

Line 1:

y = -2x + 3\\\\2x + y = 3

Line 2:

y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2

<em>Final answer:</em>

2x + y = 3\\\frac{1}{3}x + y = -2

A bag holds 1 blue block and 3 yellow blocks. How many green blocks should be added to the bag to make the probability of random
Drupady [299]
n - the number of green blocks which is equal to the number of favourable events
1+3+n=4n - the number of all blocks, which is equal to the number of all possible outcomes

P(A)=\dfrac{n}{4+n}=\dfrac{1}{2}\\&#10;1\cdot( 4+n)=2\cdot n\\&#10;4+n=2n\\&#10;2n-n=4\\&#10;n=4&#10;

The function h(t) = -16t2 + 48t + 28 models the height (in feet) of a ball where t is the time (in seconds).
Alex17521 [72]

Answer:

64

Step-by-step explanation:

<em>[using calculus] </em>When the function h(t) reaches its maximum value, its first derivative will be equal to zero (the first derivative represents velocity of the ball, which is instantaneously zero). We have h'(t) = -32t + 48, which equals zero when t = 3/2 = 1.5. The ball therefore reaches its maximum height when t = 1.5. To find the maximum height, we need to find h(1.5), which is 64 feet.

<em>[without calculus] </em>This is a quadratic function, so its maximum value will occur at its vertex. The formula for the x-coordinate of the vertex is -b/2a, so the maximum value occurs when t = -48/(2*16), which is 1.5. The maximum height is h(1.5), which is 64 feet.
