The inequality that can be used to find the domain of f(x) is x - 3 ≥ 0.

The correct answer is the second one i.e.x minus three over or equal to zero.

Given:

Function f(x) = √x-3

The fact that a negative number cannot be used as the term in the root square, so

x - 3 ≥ 0  which implies that, x ≥ 3.

From the inequality, we can tell that the domain of the function is the interval [3,∞).

Hence the inequality is x - 3 ≥ 0.

The amount in pounds of water that's been carried by Devin as described by the ratio given in the task content is; 10.5 pounds.

It follows from the task content that the amount of water Devin is carrying is to be determined.

On this note, since the backpack contains food, water, bedding, and emergency supplies are in the ratio; 2 : 3 : 1 : 4.

It therefore follows from proportion that the ratio representation of total of all supplies is; (2 + 3 + 1 + 4) = 10.

Therefore, since the total weight is; 35 pounds, it follows that the amount of water Devin is carrying can be of help as follows;

w/35 = 3/10.

w = (3 × 35)/10

w = 105/10

w = 10.5 pounds.

Ultimately, the total weight of water Devin is carrying is therefore; 10.5 pounds.

     The number that produces zero when multiplied by an is known as the additive inverse of a number, or a, in mathematics. The opposite (number),[1] sign change,[2] and negation are other names for this number. [3] The additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive, when applied to a real number. The additive inverse of zero is zero.

   Subtraction, which can be seen as adding the opposite, is closely related to additive inverse:

   a − b  =  a + (−b).

On the other hand, additive inverse can be compared as subtracting from zero:

−a = 0 − a.

As a result, the unary minus sign can be used to represent subtraction without using the "0" symbol, even though there shouldn't be a space after the unary "-" in proper typography.

 Negation has the following algebraic characteristics in addition to the identities mentioned above:

It is an Involution operation when (a) = a.

−(a + b) = (−a) + (−b)

−(a − b) = b − a

a − (−b) = a + b \s(−a) × b = a × (−b) = −(a × b)

(−a) × (−b) = a × b

Particularly, (a)2 = a2.

The error that the customer made was that he subtracted 3 from 10 instead of dividing 3 by 10.

It is given in the question that at the clothing store T-shirts are on sale, 3 for $10. A customer at the store says that one T-shirt should cost $7 at this rate.

We have to find the error made by the customer while calculating the rate of a T- shirt.

To find the rate of a shirt we will divide the number of shirts by the total amount.

Hence, the rate of a shirt will be $  10/3

But the customer subtracted 3 from 10 to get $ 7 as the rate of a T-shirt.

Hence, the customer subtracted 3 from 10 instead of dividing 3 by 10.

ANSWER:

80°

STEP-BY-STEP EXPLANATION:

Since the sides XZ and YZ are equal, the angle We know that the sum of all the angles is equal to 180 °, therefore:

We want to know which values of m satisfy ≤

5m + 1 4

Substracting 1 both sides:

-1 - 1

+03

5m ≤ 3

Dividing by 5 both sides

/5/5

m ≤ 3/5

m ≤ 0.6

Since 1 and 2 are higher than 0.6 and 0 ≤ 0.6

Then if m=0 it is satisfied

Since the two triangles in the given are similar triangles, we now know that they both have the same angle, but scaled, meaning they have different side lengths.

Base on the given, XA = 15, while XZ = 27

We can now assume that if XA : XZ, BA : YZ

We can rewite this as:

Now, plugging in the values of XA, XZ, and BA, we can now solve for YZ.

We now see that the length of YZ is 36 inches.

Next, to solve for XY, we will use the same method, but this time we will be using XB instead of BA.

Therefore, XY is 18 inches long.

we have the function

h(x)=-3x-1

this is the equation of a line

To graph a line we need at least two points

so

Find out the intercepts

step 1

Find out the x-intercept (value of x when the value of y=0)

For h(x)=0

substitute

0=-3x-1

3x=-1

x=-1/3

the x-intercept is (-1/3,0)

as the value is a fraction, take another point

For x=2

h(x)=-3(2)-1

h(x)=-7

we have the point (2,-7)

step 2

Find out the y-intercept (value of h(x) when the value of x=0)

For x=0

h(x)=-3(0)-1

h(x)=-1

the y-intercept is (0,-1)

step 3

we have the points

Using the exterior angle theorem, the value of x in the triangle is: x = 8.

The exterior angle theorem states that the measure of the angle formed outside a triangle when a side is extended through one of the points of the triangle is equal to the sum of the remote interior angles of the triangle.

Triangle LMN is shown in the diagram attached below, where:

The measure of angle MNO = (5x + 2)°

The measure of angle NLM = (x + 10)°

The measure of angle LMN = (x + 16)°

Therefore:

Measure of angle MNO = measure of angle NLM + measure of angle LMN [based on the exterior angle theorem]

Substitute

(5x + 2)° = (x + 10)° +  (x + 16)°

Solve for x

5x + 2 = x + 10 +  x + 16

Combine like terms

5x + 2 = 2x + 26

5x + 2 - 2x = 2x - 2x + 26 [subtraction property of equality]

3x + 2 = 26

3x + 2 - 2 = 26 - 2  [subtraction property of equality]

3x = 24
