Simplify (5 x + 1) - (-10 x + 6)

tekilochka [14]

Answer:15x+7

Step-by-step explanation:

First you would see that the -(-10x+6) would turn into 10x+6 meaning that the whole equation would turn into 5x+1+10x+6. Then add the x numbers together and the whole numbers separate. So now your answer should be 15x+7

29.

$f(x) = -x^2-7x-6$

As $x \to \pm \infty$ , $y \to - \infty$ .

This can be easily verified by looking at the graph (graph of a quadratic equation).

30.

The growth of a population is not linear, it's exponential.

31.

Exponential growth > polynomial, so $y = 3^x$ .

35.

$V(t) = 30\cdot (25)^{\frac{t}{20}}$

The question is asking V(t) for t = 40.

$V(40) = 30\cdot (25)^{\frac{40}{20}} \\~\\V(40) = 30\cdot 25^2 \\~\\V(40) = 30\cdot 625 \\~\\V(40) = 18750$

36.

The point of symmetry of a quadratic equation $y = ax^2+bx+c$ is at its vertice:

$V_x = \dfrac{-b}{2a}$

$V_x = \dfrac{6}{2}$

$V_x = 3$

The line is x= 3.

1000^m / 100^n can be written in the form of 10^z express z in terms of m and n

Julli [10]

Answer:

z = 3m - 2n

Step-by-step explanation:

$\frac{ {1000}^{m} }{ {100}^{n} } = {10}^{z} \\ \\ \frac{ {10}^{3m} }{ {10}^{2n} } = {10}^{z} \\ \\ {10}^{3m - 2n} = {10}^{z} \\ \\ 3m - 2n = z \\ \\ \huge \red{ \boxed{z = 3m - 2n}}$
