Which number is a rational, an integer, and a real number?

I did everything but I got confused on finding m

Kobotan [32]

m before the angle symbol stands for angle

angle acb = 180 - 108 = 72 degrees

180 = a+b+ angle acb

180 = a + 32 +72

180 = a + 110

A = 70

Which set of ordered pairs represents a function? {(−1,−3),(0,−7),(3,3),(3,−4)} {(7,9),(−5,7),(−5,8),(4,−4)} {(−6,−1),(−8,4),(−5

Jlenok [28]

Ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.

As given in the question,

Given set of ordered pairs following is the one which represents the function :

{(−1,−3),(0,−7),(3,3),(3,−4)}

In the given set of ordered pair for input value 3 there are two outputs 3 and -4 , therefore it is not a function.

{(7,9),(−5,7),(−5,8),(4,−4)}

In the given set of ordered pair for input value -5 there are two outputs 7 and 8 , therefore it is not a function.

{(−6,−1),(−8,4),(−5,4),(3,−9)}

In the given set of ordered pair each input has unique single output. Therefore it is a function.

{(−1,0),(−1,−4),(8,−3),(−4,−6)}

In the given set of ordered pair for input value -1 there are two outputs 0 and -4 , therefore it is not a function.

Therefore, ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.

A line with a slope -2 passes through the point (-1,4). Which equation represents this line in point-slope form?

sesenic [268]

9514 1404 393

Answer:

y-4 = -2(x+1)

Step-by-step explanation:

The point-slope equation of a line is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

You have m = -2 and (h, k) = (-1, 4). Putting these numbers into the above form gives ...

y -4 = -2(x +1)

The weight of an object on the moon varies directly with its weight on the earth. If an object weighing 95 lbs on the moon weigh

Luda [366]

ANSWER

450lb

EXPLANATION

If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.
$m \propto \: e$
We introduce the constant of proportionality to obtain,

$m = ke$

When, m=95, e=570,

This implies that,

$95 = 570k$
$k = \frac{95}{570}$

$k = \frac{1}{6}$

The equation now becomes,

$m = \frac{1}{6} e$

We want to find e, when m=2700,

$m = \frac{1}{6} \times 2700$

$m =450lb$
