Which of the following lines is perpendicular to y = -5x - 2?

kykrilka [37]

Answer: c is perpendicular to y = -5x - 2

Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.)

You can take a look at my notes for further clarification. Hope this helps!

Select the three ratios that represent the number of red cars to blue cars.

Lorico [155]

Three ratios that represent the number of red cars to blue cars are

2 : 3

6 : 9

8 : 12

$\texttt{ }$

<h3>Further explanation</h3>

<u>Given:</u>

Number of Red Cars = 4

Number of Blue Cars = 6

<u>Asked:</u>

Ratio = ?

<u>Solution:</u>

<em>Let:</em>

<em>Number of Red Cars = R</em>

<em>Number of Blue Cars = B</em>

The ratio that represent the number of red cars to blue cars is :

$R : B = 4 : 6$

We can find other ratio by dividing or multiplying the above comparison with the same number :

$R : B = (4/2) : (6/2) = 2 : 3$

$R : B = (4 \times 2) : (6 \times 2) = 8 : 12$

$R : B = (4 \times \frac{3}{2}) : (6 \times \frac{3}{2}) = 6 : 9$

$\texttt{ }$

<h3>Conclusion:</h3>

Three ratios that represent the number of red cars to blue cars are:

2 : 3

6 : 9

8 : 12

A1 = 10 and an =an -1 +2

Vesna [10]

I assume you're asking to solve for the n-th term in the sequence, $a_n$ .

From the given recursive rule,

$a_n = a_{n-1} + 2 \implies a_{n-1} = a_{n-2} + 2$

and by substitution,

$\implies a_n = a_{n-2} + 2\times2$

Similarly,

$a_n = a_{n-1} + 2 \implies a_{n-2} = a_{n-3} + 2$

$\implies a_n = a_{n-3} + 3\times2$

The pattern continues, so that we can write the n-th term in terms of the 1st one:

$a_n = a_1 + (n-1)\times2 \implies a_n = 10 + 2(n-1) = \boxed{2n+8}$

So the first few terms of the sequence are

{10, 12, 14, 16, 18, 20, …}
