Answer:

$2x^3+17x^2+2x-3$

Step-by-step explanation:

$\left(2x+1\right)\left(x^2+8x-3\right)\\=2xx^2+2x\cdot \:8x+2x\left(-3\right)+1\cdot \:x^2+1\cdot \:8x+1\cdot \left(-3\right)\\=2x^3+17x^2+2x-3$

In this equation, the variables were isolated to simplify the problem, following the order of operations. Negative-three either became an exponent or positive integer, 3, subtracted by a byproduct of the previous equation.

Answer:

8.−2x^2+6x

9.y-1

Step-by-step explanation:

8.(−2x)(x−3)

=(−2x)(x+−3)

=(−2x)(x)+(−2x)(−3)

=−2x^2+6x

9. y^2−y

= y^2−y

=y−1

The function A=A_oe^{-0.01155x} A = A o e − 0.01155 x models the amount in pounds of a particular radioactive material stored in

vivado [14]

They are essentially asking us to solve:

$357=900e^{-0.01155x} \implies\\ \frac{357}{900}=e^{-0.01155x} \implies\\ \ln{\frac{357}{900}}=-0.01155x \implies \\ x\approx 80.1$

Solving this equation for x tells us that it will take around 80.1 years for the materials in the vault to reduce to 357 pounds.

What are the solutions

Lapatulllka [165]

A and F are the only set of ordered pairs that work in both of the equations above. In order to find these you must place them into each equation and check for truth. Below is the work for A and F.

Ordered Pair A : (0,6)

y > 6x + 5
6 > 0 + 5
6 > 5 (TRUE)

y < -6x + 7
6 < 0 + 7
6 < 7 (TRUE)

Ordered Pair F : (-2, 18)

y > 6x + 5
18 > - 12 + 5
18 > -7 (TRUE)

y < -6x + 7
18 < 12 + 7
18 < 19 (TRUE)
