Answer: y=1/2(x)
step by step solution: you are give two points (-1,-2) and (1,2) so we can go ahead and set up our equation in slope-intercept form which is y=mx+b. m is equal to slope so we are going to find the slope first in order to do this we take both of the points given and see how much the rise over run is. (-1,-2) and (1,2) so to go from the first point to the second point you have to rise 2 units and you have to go over 4 units, this means that our rise over run or (slope) is equal to 2/4 but we are gonna simplify this down to 1/2. now we will plug this in to the equation we have set up the outline for. slope is (m) so plug in 1/2 for (m). y=1/2(x)+b. the next step is to find the y-intercept which (b) represents in this equation. in order to find the y-intercept you simply plug in (0) for (x) and solve to find (b). y=1/2(0)+b after you work this out you see that you are left with 0=b so this means that the y-intercept is 0 this means that you don't have to have the +(0) where (b) would be located. therefore your left with the equation y=1/2x. this is your final answer. hope I helped. have a great day!

Answer:

base = 18.89

legs = 16.89

Step-by-step explanation:

x + x + 68 = 180

2x + 68 = 180

2x = 112

x = 56

The altitude = 14

Tan(56) = opposite / adjacent

adjacent = base

opposite = altitude

Tan(56) = opposite / base                Multiply both sides by the base

base * Tan(56) = opposite                Divide by Tan(56)

base = opposite / Tan(56)

base = 14/tan(56)

base = 9.443

The base is actually twice this length because the altitude lands on the midpoint of the opposite side and is perpendicular to the third side (base).

base = 18.886  

Legs are the hypotenuse formed by 1/2 the base and the attitude.

Sin(56) = opposite / hypotenuse

Sin(56) = altitude / hypotenuse

hypotenuse = altitude / Sin(56)

hypotenuse = 14 / sin(56)

hypotenuse = 16.887

Rounded

base = 18.89

legs = 16.89

Jason has two bags with 6 tiles each.
dimaraw [331]

Answer:

1/4.

Step-by-step explanation:

I am assuming that there are 3 even and 3 odd tiles in each bag.

Probability( drawing an even tile form one bag) = 3/6 = 1/2.

The probability  of drawing  an even from the first and an even from the second = 1/2 * 1/2 = 1/4 (answer).

The individual probabilities  are multiplied because the 2 events are independent.

graph the parabola y equals negative x squared + 3 to graph a parabola plot the vertex and four additional points two on each si
Nataliya [291]

You don't have the graph icon here, so we'll have to graph this parabola without it.


Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).


Plot (0,3). Besides being the vertex, this point is also the max. of the function.


Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.

What times what equals 19?
Triss [41]
Since 19 is a prime number it is not divisible by 2. So its only divisible numbers are 1 and 19 itself. So 19 multiplied by 1 equals 1
