x + 2y = -4 in graph

Answer:

Domain: (-∞, ∞)

 Range: (0,∞)

Step-by-step explanation:

Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis unless a value has been added to it. If it has, the curve shifts. This function has addition on the exponent but not to the whole function so it does not change the asymptote. Its y - values remain between 0 and ∞. This is the range, the set of y values.

However, the range of exponentials can change based on the leading coefficient. If it is negative the graph flips upside down and its range goes to -∞. This doesn't have it either.

The addition to 1 on the exponent shifts the function to the left but doesn't change the range.

In exponential functions, the x values are usually not affected and all are included in the function. Even though it shifts, the domain doesn't change either. Its domain is (-∞, ∞).

Domain: (-∞, ∞)

 Range: (0,∞)

Answer:

m = 8

Step-by-step explanation:

-8 = -16 + m

Switch sides.

-16 + m = -8

Add 16 to both sides.

Because that give you something like this [tex]\frac{a}{0}[/tex] who is undefined.

Step-by-step explanation:

When you raise something to a negative exponent give you:

[tex]a^{-b} = \frac{1}{a^b}[/tex]

Then if [tex]a[/tex] is equal to 0 is considerate undefined because whatever number raising 0 is equal to 0.

Answer:

A unit rate means a rate for one of something.

Step-by-step explanation:

We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Step-by-step explanation:

[tex] = \frac{ |15 - 12| }{4} - | \frac{ - 21 + 9}{8} | [/tex]

[tex] = \frac{ |3| }{4} - \frac{ | - 12| }{ |8| } [/tex]

[tex] = \frac{3}{4} - \frac{12}{8} [/tex]

[tex] = \frac{3}{4} - \frac{6}{4} [/tex]

[tex] = - \frac{3}{4} [/tex]

Option → B

The simplified value of the Expression [tex]\(\left| \frac{(15 - 12)}{4} \right| \times \left| \frac{(-21 + 9)}{8} \right|\)[/tex] in fractional form is 9/8.

To simplify the expression: [tex]\(\left| \frac{(15 - 12)}{4} \right| \times \left| \frac{(-21 + 9)}{8} \right|\)[/tex]

Step 1: Perform the calculations inside the absolute value signs:

[tex]\(\left| \frac{3}{4} \right| \times \left| \frac{-12}{8} \right|\)[/tex]

Step 2: Simplify the fractions inside the absolute value signs:

[tex]\(\left| \dfrac{3}{4} \right| \times \left| \dfrac{-3}{2} \right|\)[/tex]

Step 3: Evaluate the absolute values of the fractions:

[tex]\(\left| \dfrac{3}{4} \right| = \dfrac{3}{4}\)[/tex]

This is because the absolute value of any positive number is itself

[tex]\(\left| \dfrac{-3}{2} \right| = \dfrac{3}{2}[/tex]

and, the absolute value of a negative number is the positive version of that number.

Step 4: Multiply the absolute values:

= 3/4 x 3/2

Step 5: Multiply the fractions:

= 9/8

So, the simplified expression is 9/8.

Answer:

Step-by-step explanation:

12C4=495

10C2-5=40

40*6=240

240/495=48/79

The probability that there is exactly 1 matching pair of socks among these 4 socks is 48/79

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Give:

Dragomir has 6 pairs of socks in a drawer.

So, [tex]^{12}C_4[/tex]

= 12! / 8! 4!

= 12 x 11 x 10 x 9 x 8! / 8! x 4x 3x 2

=495

again,

[tex]^{10}C_2[/tex]-5

= 10! / 8! 2! - 5

=45 - 5

=40

Thus, for 6 pairs of socks

= 40*6

=240

Hence, probability that there is exactly 1 matching pair of socks among these 4 socks  = 240/495=48/79.

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Use the Pythagorean Theorem to determine if these sides are sides of a right triangle.

[tex]a^{2}+b^{2}=c^{2}[/tex]

Plug in your length sides. Have the longest side represent your c variable.

a= 24

b= 45

c= 49

Solve for the equation.

[tex]24^{2}+45^{2}=49^{2}[/tex]

576+2025= 2401

2601=2401

These side lengths in a triangle are not a right triangle because 2601 does not equal 2401.
