Answer:
The first term should be positive, the second term should be positive, the last term should be -1 1/2 rather than -1 1/4
Step-by-step explanation:
A negative multiplied by a negative results in a positive. The first two terms were negatives multiplied by a negative, yet Daniel still wrote them as negative. This is an error.
Additionally, there is a multiplication error in the third term. 2 times 3/4ths does not equal 1 1/4.
Answer:
Solution given:
Centre(h,k)=(-5,-9)
radius (r)=7
we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
Substituting value;
(x+5)²+(y+9)²=7²
<u>(x+5)²+(y-9)²=49 is a required equation of a circle</u>.
The answer to your question would be D.
there is no way to tell if any of the other options are true or not so the only possible choice would be D.
Hope this helps! :)
I believe that the scale factor is 7. Hope I helped!
$ 10
250 * 2 =300
5*2=10
So the answer is $ 10
