Raising the stakes.
Creating crucial conflicts.
Making the reader ask questions.
Allowing tension to ebb and flow.

Which of the following are solutions to 2x2 – 8x - 90? Select all that apply.

Bond [772]

Answer:

x=-5, x=9

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$2x^{2} -8x-90$

equate to zero

$2x^{2} -8x-90=0$

so

$2=-1\\b=-8\\c=-90$

substitute in the formula

$x=\frac{-(-8)\pm\sqrt{-8^{2}-4(2)(-90)}} {2(2)}$

$x=\frac{8\pm\sqrt{784}} {4}$

$x=\frac{8\pm28} {4}$

$x=\frac{8+28} {4}=9$

$x=\frac{8-28} {4}=-5$

therefore

The solutions are x=-5, x=9

Answer:

Step-by-step explanation:

$3x^{2} + 5x-12=0$

$-12=-5x-3x^{2}$

$(-12=-5x-3x^{2} ) * -1$

$\sqrt{12=5x+3x^{2}$

Answer:

8. Louis

9. Rose; Raymond

Step-by-step explanation:

8. An exponent represents the number of times the base appears as a factor in the product.

We use a coefficient to signify repeated addition: 3x means x+x+x.

We use an exponent to signify repeated multiplication. x³ means x·x·x.

So, the expression ...

$4^2\cdot 4^5\text{ means }(4\cdot4)\cdot(4\cdot4\cdot4\cdot4\cdot4)$

You can see that the factor 4 appears 7 times in the product, so would be represented in exponential form as ...

$4^2\cdot4^5=\boxed{4^7}$

Louis has correctly observed this fact. In general, we see that multiplying powers of the same base causes those powers to be added.

9.

<u>Part A</u>. Rose is correct for the same reason as in problem 8.

5^5 · 5^2 = 5^(5+2) = 5^7

<u>Part B</u>. Raymond is correct. We know that division cancels similar terms from the numerator, so ...

$\dfrac{7^9}{7^5}=\dfrac{7\cdot7\cdot7\cdot7\cdot7\cdot7\cdot7\cdot7\cdot7}{7\cdot7\cdot7\cdot7\cdot7}=7\cdot7\cdot7\cdot7=7^{9-5}=7^4$

__

The rules of exponents we're using here are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)
