Answer:

$\large\boxed{x=-2}$

Step-by-step explanation:

How to solve equations?

To solve equations we use four mathematical operations: Addition, Subtraction, Multiplication and Division. Most of the time, two or more of these operations will be needed.

The first operation to be used in this equation is Multiplication. What's going to be multiplied is $-5$ by $6x+6$ :

$-5(6x+6)=30$

$-30x-30=30$

→ Add $30$ to both sides.

$-30x=60$

→ Divide $-30$ into both sides.

$-30x=60$

$-x=2$

→ Multiply both sides by $-1$ .

$x=-2$

Graph the equation shown below by transforming the given graph of the parent function.

zheka24 [161]

Answer:

Step-by-step explanation:

The graph shown is f(x)=y=|x|

The required graph is g(x) = |x|-3 = f(x) -3

In general, the graph of f(x)-3 is 3 units below f(x), and has the same shape.

See attached graph. y=f(x)=|x| in blue, f(x)-3 = |x|-3 in red.

Please help badly I cannot answer

Ne4ueva [31]

So, you asked 356 folks if they like drawing, 89 say they do.

now, if we take 356 as the 100%, what is 89 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
356&100\\
89&x
\end{array}\implies \cfrac{356}{89}=\cfrac{100}{x}\implies x=\cfrac{89\cdot 100}{356}$

12 ducks fly overhead. Each of 6 hunters picks one duck at random to aim at and kills it with probability 0.6. What's the expect

nexus9112 [7]

Answer:

The expected number of hunters who hit the duck they aim at is 3.6

Step-by-step explanation:

Given;

number of hunters, n = 6

the probability of killing a duck, p = 0.6

The expected number of hunters who hit the duck they aim at?

In binomial distribution, the expected value is equal to the product of the number of trials and the probability of success.

The expected number of hunters who hit the duck they aim at is calculated as follows;

E = np

E = 0.6 x 6

E = 3.6

Therefore, the expected number of hunters who hit the duck they aim at is 3.6
