Δ FCD is a right triangle ( 3² + 4² + 5² ).
10 : EB = 5 : 3
5 EB = 30
EB = 6
With Pythagorean theorem:
CE² = 10² - 6² = 10 - 36 = 64
CE = 8
ED = 5
AB = 2 · 5 = 10
Answer: The length of the side AB is 10.

the stairway to a cellar has a slope of -4/3, and the cellar is 2m below the ground. the equation y=-4/3x-2 models the stairway.
8_murik_8 [283]

Shown below

<h2>Explanation:</h2>

The stairway to a cellar has a slope of -4/3, that is:

m=-\frac{4}{3}

On the other hand, the cellar is 2m below the ground. In other words:

y-intercept: \\ \\ b=-2

So this can be modeled by the equation of the line:

y=-\frac{4}{3}x-2

The line has a y-intercept at point (0, -2) and as x increases 3 units y decreases 4 units. So:

x=3 \\ \\ y=-\frac{4}{3}(3)-2=-6 \\ \\ (3,-6) \ is \ also \ a \ point \ on \ the \ line

Finally, let's draw a line that passes through:

(0,-2) \ and \ (3,-6)

By using graphing tool, we get the line shown below.

Given the original statement "If a number is negative, the additive inverse is positive,” which are true? Select three options.
Sergeu [11.5K]

Answer:

The three options are;

1) If p = a number is negative and q = the additive inverse is positive, the original statement is p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement the inverse of the original statement is ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q

Step-by-step explanation:

Given a statement if p then q, we have, p → q. The converse of the original statement is then, if q, then p while the inverse of the original statement is then if not p then not q, and the contrapositive statement is then if not q then not p

Mathematically, we have;

The given conditional statement;

If a number is negative, the additive inverse is positive which can be expressed as follows;

The conditional statement is p → q

The converse statement is q → p

The inverse statement is ~p → ~q

The contrapositive statement is ~q → ~p

Therefore, we have;

1) The conditional statement, if p = a number is negative and q = the additive inverse is positive, the original statement which is a conditional statement is therefore p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement, which is a conditional statement is p → q, the inverse of the original conditional statement is therefore, ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the original statement, which is a conditional statement is therefore, q → p, the contrapositive of the original conditional statement  is therefore ~p → ~q.
