Take the second equation and solve for y.

y - 3 = x

y = x + 3

Substitute this back into the first equation and solve for x.

x + 3 = x^2 + 3.

x = 0.

Plug this into either equation to get y.

This will be give a solution of...

x=0, y=3

If you find my answer helpful, please brainliest me!

pentagon [3]

Answer:

Brian has $776 more account in his account than Chris.

Step-by-step explanation:

Compound interest Formula:

$A=P(1+r)^t$

$I$ = A-P

A= Amount after t years

P= Initial amount

r= Rate of interest

t= Time in year

Given that,

Brian invests $10,000 in an account earning 4% interest, compounded annually for 10 years.

Here P = $10,000 , r= 4%=0.04, t=10 years

The amount in his account after 10 years is

$A=10000(1+0.04)^{10}$

=$14802.44

≈$14802

Five years after Brian's investment,Chris invests $10,000 in an account earning 7% interest, compounded annually for 5 years.

Here P = $10,000 , r= 7%=0.07, t=5 years

The amount in his account after 5 years is

$A=10000(1+0.07)^{5}$

=$14025.51

≈$14026

From the it is cleared that Brian has $(14802-14026)=$776 more account in his account than Chris.

AREA ADDITION AND SUBTRACTION URGENT?

Novay_Z [31]

The area of shaded region is

$A_{shaded}=A_{circle}-A_{segment}$ .

Find the area of circle and segment:

$A_{circle}=\pi r^2=\pi (8.35)^2=69.7225\pi=219.0397,\\ A_{segment}=A_{sector}-A_{triangle},\\ \\A_{sector}=\dfrac{r^2 \alpha}{2} =\dfrac{(8.35)^2\cdot \frac{5}{9}\pi}{2}=19.3674\pi=60.8445,\\ \\A_{triangle}=\dfrac{1}{2}r^2\sin \alpha=\dfrac{1}{2}(8.35)^2\sin 100^{\circ}=34.3316,\\ \\A_{segment}=60.8445-34.3316=26.5129$ .

Then $A_{shaded}=A_{circle}-A_{segment} =219.0397-26.5129=192.5268$ .

The area of shaded region rounded to the nearest tenth is 192.5 sq. ft.

Answer: 192.5 sq. ft.
