The answer is: " x ≤ - 20 " .
______________________________________
"x " is LESS THAN OR EQUAL TO " -20 " ;
______________________________________
→ in which:

"x" refer to the number of points;
"-20" refers to the maximum number of points" ;

The fact that the maximum number of points is a "negative number"—as given in this very question/problem—indicates a "point deficit" .

Which of the following lines is perpendicular to the line Y = 3x -4

andriy [413]

Answer:

D.

Step-by-step explanation:

When a line is perpendicular to another, their slopes will be opposite reciprocal. For example, 1 would be -1, -3 would be $\frac{1}{3}$ , and $\frac{5}{1}$ would be -5. The equation is written in slope-intercept form:

$y=mx+b$

m is the slope, so find the equation with the opposite reciprocal of 3, $-\frac{1}{3}$ :

$y=-\frac{1}{3} x+4$ is the only option with the correct slope, so the answer is D.

Find cot theta if 180° < theta < 270° and cos theta = - sqrt 3/2

avanturin [10]

Answer:

cot theta = -√3

Step-by-step explanation:

we are given that cos theta = - √3/2 within the range 180° < theta < 270° and

since cos theta = adj/hyp

adj = - √3

hyp = 2

Get the opposite using the pythagoras theorem

hyp^2 = opp^2 + adj^2

2² = opp² + (-√3)²

4 = opp² + 3

opp² = 4-3

opp² = 1

opp = 1

tan theta = opp/adj

tan theta = - 1/√3

Recall that cot theta = 1/tan theta

cot theta = 1/(-1/√3)

cot theta = -√3

C an you simplify 5^-8 x 5^4

EastWind [94]

Answer:

1/625

Step-by-step explanation:

Exponent Rule: $(b^m)(b^n) = b^{m+n}$

Exponent Rule: $b^{-m}=\frac{1}{b^m}$

5⁻⁸ · 5⁴ = -8 + 4 = -4

5⁻⁴

1/5⁴

Mark signed an appointment to receive internet service on his mobile phone for the service he pays a monthly fee plus a charge f

FinnZ [79.3K]

Answer:

<em>Mark used 6.43 megabytes of data.</em>

Step-by-step explanation:

The given equation is: $5.25+0.3m=7.18$ , where $m$ is amount of data used in megabyte.

For finding the amount of data Mark used, <u>we need to solve the above equation for $m$ </u>.

First subtracting 5.25 from both sides, we will get.....

$5.25+0.3m-5.25= 7.18-5.25\\ \\ 0.3m=1.93$

Now, dividing both sides by 0.3 ...........

$m=\frac{1.93}{0.3}=6.4333... \approx 6.43$

<em>(Rounded to the nearest hundredth)</em>

Thus, Mark used 6.43 megabytes of data.
