100 POINTS!!!! PLEASE HELP ASAP!!! EXPLANATION WOULD BE GREATLY APPRECIATED!

Dmitrij [34]

Answer:

1) B- Substitution

2) C- Elimination

3) A- Graphing

Step-by-step explanation:

x+3y=7

5x+11y=3

x = 7 - 3y

Plug this x into the second equation and solve for y first

5x-3y=3 --> (1)

2x+7y=6 --> (2)

Since making any variable the subject would involve fractions, it's better to go for elimination

7(1) + 3(2)

would eliminate y

While comparing cost and adjusting choices, a graph is a better approach because all the possibilities are right in front

Determine the area of the composite figure to the nearest whole number

Check the picture below.

so, let's notice, is really just a 2x20 rectangle with a quarter of a semicircle with a radius of 11.

$\bf \stackrel{\textit{area of a circle}}{A=\pi r^2}~~ \implies A=\pi 11^2\implies A=121\pi \implies \stackrel{\textit{one quarter of that}}{\boxed{A=\cfrac{121\pi }{4}}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\underline{\textit{area of the figure}}}{\stackrel{\textit{rectangle's area}}{(2\cdot 20)}+\stackrel{\textit{circle's quart's area}}{\cfrac{121\pi }{4}}\qquad \approx \qquad 135.03\implies \stackrel{\textit{rounded up}}{135}}$
