Find the solutions to the system of equations. Select all that apply. Y=x^2-1 y=2x-2
Sliva [168]

Answer:

Option C (1, 0)

Step-by-step explanation:

We have a system with the following equations:

y = x ^ 2-1\\\\y = 2x-2

The first equation is a parabola.

The second equation is a straight line

To solve the system, substitute the second equation in the first and solve for x.

2x-2 = x ^ 2 -1

Simplify

x ^ 2-2x + 1 = 0

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.

These numbers are -1 and -1

Therefore

x ^ 2-2x + 1= (x-1)(x-1)\\\\x ^ 2-2x + 1= (x-1)^2=0

Finally the solutions are

x = 1\\y =0

If I want to buy a pair of sunglasses and the original price is $120, how much will I pay if they are 50% off? What if they were
gogolik [260]

100 pts help me please.
Natalija [7]

<u>Answer:</u>

  • Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.

<u>Step-by-step explanation:</u>

We know that:

  • 48 + 8(b) = Carly's expenditure
  • 10(b) = Carly's expenditure
  • 48 + 8b = 10b
  • B = Boxes of cards

<u>Work:</u>

  • 48 + 8b = 10b
  • => 48 + 8b - 8b = 10b - 8b
  • => 48 = 2b
  • => b = 24

<u>Now, let's substitute the value of b into any equation.</u>

  • 10(24)
  • => 240

<u>Hence, Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.</u>

Hoped this helped.

Rewrite the rational exponent as a radical by extending the properties of integer exponents.
Aloiza [94]

\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^{-n} \qquad \qquad  a^n\implies \cfrac{1}{a^{-n}} \\\\\\ \textit{also recall that }a^{\frac{ n}{ m}} \implies  \sqrt[ m]{a^ n}  \qquad \qquad \sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}} \\\\ -------------------------------


\bf \cfrac{11^{\frac{2}{5}}}{11^{\frac{1}{4}}}\implies 11^{\frac{2}{5}}\cdot 11^{-\frac{1}{4}}\implies 11^{\frac{2}{5}-\frac{1}{4}}\implies 11^{\frac{8-5}{20}}\implies 11^{\frac{3}{20}} \\\\\\ \sqrt[20]{11^3}\implies \sqrt[20]{1331}
