For what values (cases) of the variables the expression does not exist: a/2x−4

Mathematics
1 answer:
lana66690 [7]3 years ago
5 0

Answer:

x=2

Step-by-step explanation:

Given the expression: \dfrac{a}{2x-4}

The expression is undefined or "does not exist" when the value of the denominator equals zero.

Therefore, set the denominator of the function equals to zero to find the values at which it does not exist.

2x-4=0

2x=4

x=2

Therefore, at x=2, the function is undefined.

Let l, t, b represent the numbers of lions, tigers, bears, respectively.

2l +3t +3b = 156 . . . . . . . 156 meals per day are supplied
l +t = 3b . . . . . . . . . . . . . . there are 3 times as many great cats as bears
l +t +b = 68 . . . . . . . . . . . there are a total of 68 animals

_____
The last 2 equations tell you
.. 4b = 68
.. b = 17
Subtracting 3 times the last equation from the first gives
.. -l = -48
There are 48 lions, 3 tigers, and 17 bears.

Can someone help me figure out the answer?
olga_2 [115]

Answer:

y = -2x +15

Step-by-step explanation:

The point-slope form of the equation for a line through (h, k) with slope m is ...

... y - k = m(x - h)

For your point (h, k) = (5, 5) and slope m = -2, the equation in point-slope form is ...

... y - 5 = -2(x - 5)

Simplifying, we get

... y - 5 = -2x +10

Adding 5 puts the equation into slope-intercept form, as you want.

... y = -2x +15
