Answer:

See below.

Step-by-step explanation:

6.)

y - 2 = 3(x - 6)

y - 2 = 3x - 18

y = 3x - 16

4.)

y - (-2) = 3(x - 5)

y + 2 = 3x - 15

y = 3x - 17

3.)

y - 7 = 2(x - 4)

y - 7 = 2x - 8

y = 2x - 1

Answer: Choice C.  (-3.5, -3)

========================================================

Explanation:

Draw a vertical number line. Make sure to plot the points -3 and -4 on this number line. We'll have -4 below -3. In between these values is -3.5

The ceiling function brings the point -3.5 up to -3. Think of an elevator that visits each floor of a skyscraper. Each floor being a positive or negative whole number on this number line. So when x = -3.5, this means f(x) = -3. This points to choice C being the answer.

As another example, if x = 5.7, then f(x) = 6. Yet another example would be x = 2.008 leads to f(x) = 3. We always move up to the closest integer.

Answer:

B:3

Step-by-step explanation:

Answer: (20-0.6P)

Step-by-step explanation:

Given: Elijah buys ​P​ pounds of bananas for ​60 cents per pound​.

Since 1 dollar = 100 cents

Then,  60 cents = [tex]\$\dfrac{60}{100}=\$0.6[/tex]

Cost of P pounds of bananas = Cost per pound x P

= $0.6 P

He ​pays ​the clerk with a twenty-dollar bill​.

Change he will get = $ 20 - Cost of P pounds of bananas

= $ (20-0.6P)

Hence, the expression of the change Elijah will get =  (20-0.6P)

The equation which represents the function is y=-1/3x

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We have to find equation of line passing through points (-9, 3) and (-12, 4)

slope = 4-3/-12+9

=1/-3

=-1/3

Now let us find y intercept

3= -1/3(-9)+b

3=3+b

b=0

Hence, the equation which represents the function is y=-1/3x

Answer: To figure out the answer, you have to find c, c equals 0 because adding anything from 9 + 1 equaling 0 will get you above the answer, 10. so, 9c + 1 = 10, now lets change the equation to 9c(0) + 1 = 10, c equaling zero would make the most sense because if c equals 0 then you will get 10, the answer.

Answer:

Step-by-step explanation:

There will be one unique solution of the equation y = 5x - 1 and y = 3x + 7. The correct option is B.

A finite collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.

A linear equation can only have one unique solution, which is a location at which the LHS and RHS of the equation are equal. There is only ever one solution to a linear equation with one variable.

y = 5x - 1

y = 3x + 7

5x - 1 = 3x + 7

2x = 8

x = 4

y = 19

Therefore, there will be one unique solution of the equation y = 5x - 1 and y = 3x + 7.

Answer:

x-2 is a factor of following polynomials:

Step-by-step explanation:

In order to check that which polynomials might have x-2 as a factor, we will put

x-2 = 0 => x = 2 in each polynomial, if the value of polynomial on 2 is zero then x-2 is a factor otherwise not.

So,

a(x) = 6x² - 7x - 5

Putting x = 2

[tex]a(2) = 6(2)^2-7(2)-5\\= 6(4)-14-5\\=24-14-5\\=24-19\\=5 \neq 0[/tex]

b(x) = 3x² + 15x - 42

[tex]b(2) = 3(2)^2 + 15(2) - 42\\=3(4)+30-42\\=12+30-42\\=42-42 = 0[/tex]

c(x) = 2x³ + 13x² + 16x + 5

[tex]c(2) = 2(2)^3 + 13(2)^2 + 16(2) + 5\\=2(8)+13(4)+32+5\\=16+52+32+5\\=105 \neq 0[/tex]

d(x) = 3x³ - 2x² - 15x + 14

[tex]d(2) = 3(2)^3 - 2(2)^2 - 15(2) + 14\\= 3(8)-2(4)-30+14\\=24-8-30+14\\=38-38 = 0[/tex]

e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70

[tex]e(2) = 8(2)^4 - 41(2)^3 - 18(2)^2 + 101(2) + 70\\= 8(16)-41(8)-18(4)+202+70\\=128-328-72+202+70\\=0[/tex]

[tex]f(2) = (2)^4 + 5(2)^3 - 27(2)^2 - 101(2) - 70\\=16+5(8)-27(4)-202-70\\=16+40-108-202-70\\=-324 \neq 0[/tex]

Hence,

x-2 is a factor of following polynomials:

Answer:

56deg

Step-by-step explanation:

A triangle has 180deg.

180 = 68 + 56 + x       >> add 68 and 56

180 = 124 + x              >> subtract 124 from both sides

56 = x

The missing side is 56deg

Answer:

15 inches.

Step-by-step explanation:

Since we know its a square, we know that the side lengths are all equal. Knowing this, we know that we could find the area by taking a side length and squaring it. So we can take the square root of 219 to find the side length:

√219 = 14.79864859 ≈ 15

Therefore, the side lengths of the sign are about 15 inches.

Answer:

x cubed minus y cubed is equal to 504

Step-by-step explanation:

First we need to know what the values of x and y are.  We can do this pretty easily, by just solving both equations for x, and equating them to each other:

With the first:

x + y = 10

x = 10 - y

And with the other

x - y = 6

x = 6 + y

Now that we have two definitions of x, we can say that the expressions are equal, and solve for y:

10 - y = 6 + y

10 - 6 = y + y

4 = 2y

y = 2

And now that we know what y is, we can find x:

x = 10 - y

x = 10 - 2

x = 8

So x is equal to eight.  We can check our answer by plugging x into the other equation and seeing if we get the same value for y:

x - y = 6

8 - y = 6

-y = 6 - 8

-y = -2

y = 2

So we know we solved that correctly.

Now if we cube each number, eight cubed is equal to 512, and 2 cubed is equal to 8.  If we subtract the latter from the former we get 504.

so x cubed minus y cubed is equal to 504
