Answer:(a=5,b=3)
7a-3b = 26--------(1)
a + 2b =11---------(2)
on mutlplying by7 in eq 2
= 7a+14b=77-------(3)
from eq(1) and (3) (on substracting)
7a+14b=77
7a-3b=26
________
=-17b=51
b=51/17
b=3
on putting value of b in eq 1
7a-3b = 26
=7a-9=26
7a=35
a=5

Answer:
The area of the circle is 1988.1 cm.
Step-by-step explanation:
You basically have all of the instructions on how to do this in the question.
- Multiply 3.14 by the radius. 3.14 x 14.2 = 44.588
- Now you just have to square it. 44.588^2 = 1988.0897.
- And lastly we have to just round it to the nearest tenth. Rounded = 1988.1.
I hope I helped.

No, it is not, a parabola, (from this equation, which is x^2, disregarding the +8 or y-intercept) cannot be a one-to-one function, it is a many-to-one.
I believe that would be 38/55
Positive because it does not go less than 0.
