Answer:
0.05
Step-by-step explanation:
divide 100 by 20
Answer:
which is none of the choices provided.
Are you sure the question is right or even the choices?
You can even write it as:
but this is still not a choice.
Step-by-step explanation:
The vertex form of a quadratic is .
This is called vertex form because it gives you the vertex is .
We are given that which makes our equation:
.
We can find the value of by plugging in the x-intercept (7,0) for into:
Subtract 25 on both sides:
Divide both sides by 25:
.
So the equation for the quadratic is:
Let's put this into factored form since all the choices are in factored form.
This will require us to multiply the (x-2)(x-2) out:
Factor out -1:
WE need to find two numbers that multiply to be -21 and add to be -4:
There was a time that a friend of mine got to a decision because the leader of the group said so (it was a group project). Although it was clear that he did not want to comply to the decision, he made it because it was what the leader said so.
Answer:
x = 14
y = 4
Explanation:
Ok so, just from looking at the two triangles i can tell they're congruent right triangles. I used different colors to show which sides of the triangle correspond and are equal to each other in my attatched photo.
So the side thats equal to x is the same length as the side that's equal to y+10 on the other triangle.
So we can write the equation x = y + 10.
Using this same method, the side that's equal to x + 2 is the same length as the side that's equal to 4y on the other triangle.
So, we can write the equation 4y = x + 2.
Now we have the equations you could rewrite to be in slope- intercept form so they're easier to graph. But a graphing calculator online would plot it just fine.
If you graph these two equations they'll intersect at the solution ( 14, 4 ). I'll include the graph in my images as well.
To check your answer, you can plug in x and y and see if the triangle sides end up being the same length. I did and it was correct.
Okay what you need I’ll help you with whatever
