Write the equation of a line in slope intercept
form that has a slope of
-2/3 and has a y-intercept of 7.

The equation of line is [tex]y+3=2(x+2)[/tex]

Option A is correct.

Step-by-step explanation:

We need to find the equation of the line.

Looking at the graph the two points are: (2,5) and (-2,-3)

We will first find the slope of these points using formula:

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

Here x₁ = -2, y₁=-3, x₂=2 and y₂=5

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5-(-3)}{2-(-2)}\\Slope=\frac{8}{4}\\Slope=2[/tex]

So, slope of the line is 2.

Considering that both lines are parallel (as not given in question). both lines will have same slope.

Now using Point slope form to find the equation.

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

Using point (-2,-3) and slope m= 2

[tex]y-y_1=m(x-x_1)\\y-(-3)=2(x-(-2))\\y+3=2(x+2)[/tex]

So, the equation of line is [tex]y+3=2(x+2)[/tex]

Option A is correct.

Answer:

Ten added to the difference of six and four. Or, the difference of six and four added to ten.

Step-by-step explanation:

The word phrase for the mathematical expression 10+(6-4) is 'Ten plus the difference of six and four'. It is the representation of the arithmetic operation in a sentence format.

The word phrase for the mathematical expression 10+(6-4) is 'Ten plus the difference of six and four'. In this phrase, 'Ten plus' corresponds to the 10+ part of the expression. 'The difference of six and four' means you subtract 4 from 6, which corresponds to the (6-4) part of the expression.

The expression 10+(6-4) can be simplified using the order of operations. First, we need to subtract 4 from 6, which equals 2. Then, we add the result 2 to 10, which equals 12. Therefore, the word phrase for the expression 10+(6-4) is "Ten plus the difference of six and four."

Option D: [tex](-1.6,0.8)[/tex] are the coordinates of the point P

Explanation:

It is given that "A coordinate grid shown from negative 2 to positive 2 on x-axis and negative 2 to positive 2 on y-axis. There are 4 grid lines between a whole unit of the grid".

Thus, the value of each grid is [tex]0.2[/tex]

It is also given that, "A point labeled P is shown at the intersection of 8 grid lines to the left of the y-axis and 4 grid lines above the x-axis".

Since the point P lies on the left of the y-axis and above the x-axis, the x-value will be negative and y-value will be positive.

Thus, the value of x-axis is given by

[tex]8\times0.2=-1.6[/tex]

And the value of y-axis is given by

[tex]4\times0.2=0.8[/tex]

Thus, the coordinates of the point P is [tex](-1.6,0.8)[/tex]

Hence, Option D is the correct answer.

Step-by-step explanation:

Multiplying two algebraic fractions produces a new algebraic fraction. Multiply the two numerators to get the new numerator and multiply the two denominators to get the new denominator. Then simplify by reducing the new fraction to lowest terms.

for example:

[tex]\frac{x}{y} \\[/tex]×[tex]\frac{a}{b}[/tex] = [tex]\frac{xa}{yb}[/tex]

Division of algebraic fractions

The procedure for dividing algebraic fractions is the same as the procedure for dividing common fractions.  Replace the division by a fraction by the multiplication by the reciprocal of that fraction, like this. Then carry out the multiplication of the two fractions as described above.

for example:

[tex]\frac{\frac{a}{b} }{\frac{x}{y} }[/tex]

can be written as

Answer:

The information you'll include is the amount of spaces moved from ABC to form A'B'C' which will be based on the opposite side.

To describe a translation of triangle ABC, you need to identify the direction and distance of the translation. The triangle's shape, size, and orientation remain the same after translation.

In describing a translation of triangle ABC, you would include the direction and distance of the translation. The direction could be up, down, left, or right. The distance would determine how far the triangle moves from its original position.

For instance, you may describe a translation as moving the triangle ABC 3 units to the right and 2 units down. It's important to note that under a translation, the shape of the triangle does not change. The size, shape, and orientation of triangle ABC remain consistent in the translated image.

Step-by-step explanation:

(convert the mixed fraction into proper fraction)

Ratio of the amount of juice to the amount of ginger ale = (5/2) / (20/3)

⇒ (5/2)[tex]\times[/tex](3/20)

⇒ (1/2)[tex]\times[/tex](3/4)

⇒(3/8)

∴ The ratio of juice to ginger ale is 3 : 8

Answer:

Yes.

Step-by-step explanation:

You can use the triangle inequality theorem: the sum of any two sides must be greater than the third side. You can also just check the two smallest sides.

9+12=21

21>16   --> yes it is a triangle.

hope this helped!

If the sum of the lengths of any two sides of a triangle is less than or equal to the  length of the third side, then the triangle is not possible.

If a triangle has sides with lengths of 9, 12, and 16, notice that 9 + 12 or 21 is greater than 16. So the sum of the lengths of two sides of the triangle is greater than the length of the third side.

This means that the triangle with sides of lengths

9, 12, and 16 is possible.

Final answer:

The librarian receives a total of 214 books, with the first box containing 136 books and the second box containing 78 books (58 fewer than the first).

Explanation:

To find the total number of books the librarian receives, we first need to determine how many books are in the second box. We are told that the second box has 58 fewer books than the first box, which contains 136 books. Therefore, we can calculate the number of books in the second box by subtracting 58 from 136.

The calculation for the second box will be: 136 books - 58 books = 78 books.

To find the total number of books, we then add the number of books in the first box to the number of books in the second box:

Total books = 136 books + 78 books = 214 books.

Thus, the librarian receives a total of 214 books.

Final answer:

Subtract 58 from 136 to find the number of books in the second box (78 books), then add the number of books from both the first and the second box to get the total (214 books).

Explanation:

The student has asked how to calculate the total number of books a librarian receives if the first box contains 136 books and the second box contains 58 fewer books than the first. To find the number of books in the second box, we subtract 58 from 136, which gives us 78 books. To find the total number of books received, we then add the number of books in both boxes together: 136 books from the first box plus 78 books from the second box equals 214 books in total.

Answer:

975,462.00000

Step-by-step explanation:

975,462 rounded to hundred thousand

The number 975,462 rounded to the nearest hundred thousand is 1,000,000 because the ten thousand digit (7) is more than 5.

To round the number 975,462 to the nearest hundred thousand, you have to look at the ten thousand digit. In this case, that's 7. If this digit is 5 or more, you round up the hundred thousand digits. If it is less than 5, you leave the hundred thousand digits as it is. In our number, the ten thousand digit is 7, so we round up the hundred thousand digit which is 9 to 10. Since there is no '10' in the digit system, it overflows to the next digit, making it 1,000,000. So, 975,462 rounded to the nearest hundred thousand is 1,000,000.

x = –6

Solution:

Given expression is [tex]\sqrt[3]{x-2}+5=3[/tex].

Step 1: Isolate the radical by subtracting 5 from both sides of the equation.

[tex]\Rightarrow\sqrt[3]{x-2}+5-5=3-5[/tex]

[tex]\Rightarrow\sqrt[3]{x-2}=-2[/tex]

Step 2: Cube both sides of the equation to remove the cube root.

[tex]\Rightarrow(\sqrt[3]{x-2})^3=(-2)^3[/tex]

Cube and cube root get canceled in left side of the equation.

[tex]\Rightarrow\ x-2=-8[/tex]

Step 3: To solve for x.

Add 2 on both sides of the equation.

[tex]\Rightarrow\ x-2+2=-8+2[/tex]

[tex]\Rightarrow\ x=-6[/tex]

Hence the solution is x = –6.

Answer: They are 37 feet apart each other

Step-by-step explanation:

We are told that two divers are at a certain distance between them. The first diver is at a depth of 122 ft and the second diver is at a depth of 159 feet.

Note we are talking about depth, since both divers are below sea level.

Now, if we want to know the distance that separates them, we only have to take the difference between both depths:

[tex]159 ft-122 ft=37 ft[/tex] This is the distance beweent both divers.

This means they have to reduce their distance by 2 feet in order to accomplish the safety rules.
