Squaring both sides we get,x^2-2x+1=6x+10,,,x^2-8x-9=0.factoring by middle term breaking, x^2--9x+x-9=0,(x+1)(x-9)=0,x=-1,9
Answer:
4782969
Step-by-step explanation:
the equation for finding a term (IN A GEOMETRIC series) is a1(r)^(n-1)
a1=first term
r=ratio
n=the number you want
you can see that the sequence increases by the eponent of 3 increasing y 1 each time. So for the first time 3^0=1,3^1=3, 3^2=9 and so on. So we can determine that the ratio is 3.
so now we can plug all that information into the equation
1(3)^(15-1)=the 15th term
4782969=15th term
Hope that helps :)
It would probably be 93.5. I hope this helps. have a blessed day.
The answer is d. The reason this is the answer is because to find the area of a triangle you will find half of the base times the height. The formula looks like this: A=1/2bh.
On this picture the base is the length of the bottom part of the triangle (c). It is the distance of the solid line only.
The height is represented as the straight line that is perpendicular to the base (forms a right/90 degree angle). X is the height of the triangle.
Therefore, 1/2cx is the answer.
Answer:
1) y=x-4
2)y=x+2
Step-by-step explanation:
You can see on the first one y is just 4 less than x
You can see that the second one (graph) has a slope. As by the points, if you increase x by 0.5 you increase y by one.
Thus, y=x+2
Hope this helped! I can't see much of the question :)
