How do I solve the equation (x+3)^1/2-1=x

konstantin123 [22]

Answer:

Step-by-step explanation:

$(x+3)^{\frac{1}{2} } -1=x\\(x+3)^{\frac{1}{2} } =x+1\\squaring\\x+3=x^2+2x+1\\\\x^{2} +2x-x+1-3=0\\x^2+x-2=0\\x^2+2x-x-2=0\\x(x+2)-1(x+2)=0\\(x+2)(x-1)=0\\x=-2,1$

Answer:

10,542,719

Step-by-step explanation:

The circle chart shows you that an estimated 49% of Australia's population has type O blood. Then the number expected to have type O blood is ...

0.49 × 21,515,754 ≈ 10,542,719

_____

You can choose the correct answer by recognizing that 49% is very slightly less than 1/2, so the number with type O blood will be very slightly less than half of 21 million -- about 10.5 million.

What is the equation to (-3,1) and (0,-8)

puteri [66]

The change in x between the two is 3 and the change in y is -9.
Divide -9 by 3 to get -3 using the rise over run slope formula.
The equation is y = -8 + -3x because the -8 in the second set of coordinates is the y-intercept of the equation.
Hope this helps!

You purchased a vehicle for $11,578 with a down payment of $4,100. You had 36 monthly payments of $251.34. Calculate the finance

Leona [35]

Finance charge is a fee that represents the cost of borrowing or credit.
In this equation, it shows the total amount paid through credit subtracted by the cost of vehicle.
let x be the finance charge

x = $4,100 + 36 months ($251.34/month) - <span>$11,578
</span>x = $4,100 + $9,048.24 - <span>$11,578 </span>
x = ($4,100 + $9,048.24) - $11,578
x = $13,148.24 - $11,578
x = $1,570.24.
The finance charge is $1,570.24
