X = 0, y = 4, z = -3

You can solve this by using the two equations with the z to create a fourth equation. Get the z's to equal each other my multiplying the whole equation by factors that would do so. Then subtract them from each other to get it to cancel out. Then you can use that equation along with the middle equation to solve for either x or y in the same way. Once you have one answer, you can use the middle equation to find the second one and any equation to find z.

Using the Distance Formula, find the distance between points (-1, -7) and (-3,-5) to the nearest tenth.
MrMuchimi

Answer:

The answer is

<h2>2.8</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-1, -7) and (-3,-5)

The distance between them is

d =  \sqrt{ ({ - 1 + 3})^{2}  +  ({ - 7 + 5})^{2} }  \\  =  \sqrt{ {  2}^{2}  + ( { - 2})^{2} }  \\  =  \sqrt{4 + 4}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  =  \sqrt{8}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\   = 2 \sqrt{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 2.8284271247

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you

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.
