Solution: x ≥ -5

Domain Definition: The domain of a function is the set of input or argument values for which the function is real and defined

squareroot 2x + 10  ⇒  2x + 10 ≥ 0

Solve 2x + 10 ≥ 0:

Subtract 10 from both sides

2x + 10 - 10 ≥ 0 - 10

Simplify

2x ≥ -10

Divide both sides by 2

2x / 2  ≥  -10 / 2

Simplify

2x / 2

Divide the numbers: 2 / 2 = 1

= x

Note: x has the same value as 1

Divide the numbers: -10 / 2 = -5

= -5

The function domain is

x ≥ -5

Answer:

[tex]\boxed{\text{C. }x \geq -5}}[/tex]

Step-by-step explanation:

The domain is the set of all possible x-values that will make the function work.

The definition automatically eliminate options B and D.

Your function is

[tex]y = \sqrt{2x + 10}[/tex]

The number under the radical cannot be negative, because the square root of a negative number is imaginary.

Thus, we must have

[tex]\begin{array}{rcr}2x+ 10 & \geq & 0\\2x & \geq & -10\\x & \geq & -5\\\end{array}\\\\\text{The domain is }\boxed{\mathbf{x \geq -5}}[/tex]

The graph of your function shows that the range is x ≥ -5.

Answer:

Slope: 7

y-intercept:-6

Step-by-step explanation:

The equation of the line in Slope-intercept form is the following:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

You have the equation of the given line:

[tex]y=7x-6[/tex]

You can observe that it is written in Slope-intercept form, therefore, you can identify that the slope and the y-intercept are the following:

[tex]m=7\\b=-6[/tex]

A. The slope is 7.

B. The line rises steeply right 7 units for every 1 unit increase in x.

Here's how to find the slope and y-intercept directly from the equation:

Understanding the Slope-Intercept Form:

The equation of a line can be written in *slope-intercept form* as `y = mx + b`, where:

`m` represents the slope of the line.

`b` represents the y-intercept, which is the point where the line crosses the y-axis.

Identifying Slope and Y-Intercept:

In the given equation, `y = 7x - 6`, we can directly identify the values:

The slope `m` is the coefficient of `x`, which is 7.

The y-intercept `b` is the constant term, which is -6.

Interpreting the Slope:

A slope of 7 indicates that for every 1 unit increase in `x`, the `y` value increases by 7 units. This means the line rises steeply from left to right.

Question:

Find the slope and y-intercept of the line whose equation is y= 7x-6.

Answer:

k= 2/3 2 over 3.

or 0.60%

Step-by-step explanation:

Answer:

0.04 or 1/25

Step-by-step explanation:

Note that 25^3  = 15625.

Then 15625k = 625.

Solve for k using division:

k =  625 / 15625 = 0.04

Note that we could also do the problem in this manner:

25 = 5^2

625 = 5^4

Therefore, 5^4 * k = 5^2

Dividing both sides by 5^4, we get:

         5^2                                          1

k = ------------ = 5^(2-4) = 5^(-2) or ---------- = 1/25 = 0.04 (same as before)

Here we are going to use the rule which says that

i) equal arc segments subtends equal angles at the circle

ii) The Angle subtended by any arc segment at center is double to that of the angle subtended by the same arc at its circumference.

For more details please refer to the image attached to this problem.

Let us say that the angle subtended by arc mAB at center O = 6∅

Hence , ∠AOB=6∅

Hence ∠ADB = 3∅ ( Rule ii as discussed above )

Also as length of arc mCD = x , the angle subtended by it on the center will be in the same ratio as it was subtended by arc with length 6x

Hence

∠COD=∅

Hence

∠CAD=∅/2

Hence in ΔATD

∠ATD + ∠ADT +∠DAT = 180°

∠ATD + 3∅+∅/2= 180°

∠ATD = 180° - (3∅+∅/2)    ----------(A)

Also

∠ATD + ∠ATB = 180°

From (A)

180° - (3∅+∅/2) +∠ATB =  180°

∠ATB = (3∅+∅/2)

∠ATB = (6∅+∅)/2

∠ATB = (7∅)/2

However , in order to find the exact value of∠ATB  we need to evaluate  ∅, and to find it , we must have some value of x .

Answer:

x = 6.4

Divide by 5 on both sides.

5x divided by 5 leaves x alone.

32 divided by 5 is 6.4.

The required Paola needs to use 18 cups of water.

To determine the number of cups of water Paola needs to use, we need to know the ratio of water to iced tea mix. Typically, a common ratio for making iced tea is 1 tablespoon of iced tea mix per 1 cup of water.

A ratio is a comparison of two quantities or values, typically expressed in the form of a fraction or with a colon (:). It shows the relative sizes or amounts of two or more things in relation to each other.

Given that Paola uses 18 tablespoons of iced tea mix, she would need an equal amount of cups of water.

Answer:

2x+3y-5=0

Step-by-step explanation:

We have been given two points  (4,-1) and (-2,3). Now we need to find about

what is the equation of the line that passes through (4,-1) and (-2,3).

Slope of the line through the points  (4,-1) and (-2,3)  is given by:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{3-\left(-1\right)}{-2-4}=\frac{3+1}{-6}=\frac{4}{-6}=-\frac{2}{3}[/tex]

Now plug the slope [tex]m=-\frac{2}{3}[/tex] and point (4,-1) into point slope formula

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y--1=-\frac{2}{3}\left(x-4\right)[/tex]

[tex]y=-\frac{2}{3}x+\frac{5}{3}[/tex]

or we can rewrite that as 2x+3y-5=0

Hence final answer is 2x+3y-5=0

The answer is:

The second option

[tex]2x+3y-5=0[/tex]

To know which is the equation of the line, we need to follow the next steps:

Find the slope of the line:

We are given the points:

[tex](-2,3)\\(4,1)[/tex]

Where,

[tex]x_1=4\\y_1=-1\\x_2=-2\\y_2=3[/tex]

Also, we know that we can calculate the slope of a function using the following formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Now, using the slope formula, and substituting the given points, we have:

[tex]m=\frac{3-(-1)}{-2-4}[/tex]

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

[tex]m=-\frac{2}{3}[/tex]

Find the "b" value:

In order to find "b" we need to substitute any of the given points, we know that line pass through both of the given points, so, substituting the point (4,-1), we have:

Writing the slope form of the function,

[tex]y=mx+b[/tex]

[tex]y=-\frac{2}{3}x+b[/tex]

[tex]-1=-\frac{2}{3}*(4)+b\\\\b=-1+\frac{2}{3}*(4)=-1+\frac{8}{3}=\frac{-3+8}{3}=\frac{5}{3}[/tex]

Now that we know the slope and "b", we can write the equation of the line in slope-intercept form:

Writing the equation of the equation, we have:

[tex]y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Then, by multiplying each side of the equation by 3 in order to simplify the fractions, we have:

[tex]3y=(3)*(-\frac{2}{3}x)+(3)*(\frac{5}{3})[/tex]

[tex]3y=-2x+5[/tex]

Rewriting the equation, we have:

[tex]2x+3y-5=0[/tex]

Hence, we have that the correct option is the second option, the equation of the line that passes through the given points is:

[tex]2x+3y-5=0[/tex]

Answer:

She did not buy enough border. She needs 34 ft not 30.

Step-by-step explanation:

Find the perimeter of her room in feet:

12 inches in a foot

96/12=8

3 feet in a yard

3(3)=9

8 ft + 8 ft + 9 ft + 9 ft = 34 ft

She bought 30 ft of border, which is not enough because she needs 34 ft

The given border of 30 feet is not enough.

A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter.

Given:

Two walls are each 96 inches long, and two walls are each 3 yards long.

She pays $30 for border that costs $1 per foot.

First step is to convert inches to feet

1 inch = 1/12 feet

96 / 12 = 8 feet

and,  1 yard = 3 feet

3 x 3 = 9 feet

Now, the perimeter of the room

= 9 + 9 + 8 + 8

= 34 inches

The  feet of border bought

= $30 / $1

= 30

So, 34 > 30 thus the border is not enough

Using the formula for compound interest, the total amount in the account after 10 years, with no further deposits and 3 percent interest compounded weekly, is approximately $1615.65.

This problem involves the concept of compound interest, specifically interest compounded weekly. To calculate the total amount in the account after 10 years, the formula for compound interest is used, which is A = P(1 + r/n)^(nt).

In this case, P, the principal amount, is $1200. The annual interest rate, r, is 3% or 0.03 when converted into decimal form. The number of times interest is compounded per year, n, is 52 weeks since interest is compounded weekly. Lastly, t stands for the number of years the money is invested or borrowed for, which is 10 in this instance. Plug these values into the formula to get the total amount after 10 years.

A = 1200(1 + 0.03/52)^(52*10) = $1615.65

So, if Hans makes no further deposits and the account earns 3 percent interest compounded weekly, the amount in the account after 10 years will be approximately $1615.65.
