Y - x = 2

y =




please help

Answers

Answer 1
I will solve this equation simultaneously by Substitution.

- x + y = 2
5x + 4y = 17

Solve - x + y = 2 for y:
- x + y + x = 2 + x (here we add x to both sides)
y = x + 2

Substitute x + 2 for y in 5x + 4y = 17
5x + 4y = 17
5x + 4(x + 2) = 17
5x + 4x + 8 = 17
9x + 8 = 17 (simplify both sides of the equation)
9x + 8 + (-8) = 17 + (-8) (add -8 to both sides)
9x = 9
9x/9 = 9/9 (divide both sides by 9)

x = 1

Substitute 1 for x in y = x + 2
y = x + 2
y = 1 + 2
y = 3 ( simplify both sides of the equation)

Therefore x = 1 and y = 3

Answer:

If you're supposed to use elimination to find (x, y) the answer is (6, 1)

Step-by-step explanation:

Add:

2x+3y=15

  x-3y= 3

y cancels out and left with...

2x=15

  x=3

that becomes

3x=18

find x

18/3= 6

x=6

Then plug in x (which is 6) to one of the equations to solve for y

6- 3y= 3

-3y= 3-6

-3y= -3

y= 1

(x, y) equals (6, 1)

Solve this inequality for x: -46 − 8x > 22.
A.
x -8.5
D.
x > 8.5

Answers

Answer:

x < - 8.5

Step-by-step explanation:

Given

- 46 - 8x > 22 ( add 46 to both sides )

- 8x > 68

Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity

x < - [tex]\frac{68}{8}[/tex] , that is

x < - 8.5

The vertex of the graph of f(x) = |x - 3| +6 is located at
Done
Intro

Answers

Answer:

The vertex of the graph is located at the point (3,6)

Step-by-step explanation:

Here, we want to know where the vertex of the equation if plotted will be

To get this, what we have to do is to equate the expression that we have in the absolute value to zero

After this, we then proceed to solve for the value of x

We have this as;

x -3 = 0

hence;

x = 0 + 3

x = 3

to get the y-value of the vertex, we look at the value at the side of the absolute value

This value is 6 and thus, the y-value of the vertex point is 6

So the coordinates of the vertex is (3,6)

The volume of a rectangular prism is given by the product of its length, and height. Samantha has a rectangular prism that has a length of b squared units, a width of a units, and a height and ab+c units.

Answers

Answer:

V = a²b³ + acb² units³

Step-by-step explanation:

The volume of a rectangular prism is given by :

V = l×b×h

Here, l = b² units

b = aunits

h = ab+c units

So, the volume of the prism is given by :

V = b² × a × (ab+c)

= ab²(ab+c)

= a²b³ + acb²

Hence, the required volume is a²b³ + acb² units³.

A ribbon is 5 2 5 yards long. Mae needs to cut the ribbon into pieces that are 2 5 of a yard long. How many pieces of ribbon can she cut?

Answers

Answer: The number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards

Step-by-step explanation:

Given: The length of the ribbon = [tex]5\dfrac25[/tex] yards

[tex]= \dfrac{5\times5+2}{5} =\dfrac{27}{5}[/tex] yards

Length of each piece = [tex]\dfrac25[/tex] yards

The number of identical pieces can be cut from the entire ribbon = (Length of the ribbon ) ÷ (Length of each piece )

[tex]=\dfrac{27}{5}\div\dfrac{2}{5}\\\\=\dfrac{27}{5}\times\dfrac{5}{2}\\\\=\dfrac{27}{2}\\\\=13\dfrac12[/tex]

Hence, the number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards

solve for x
350 = 25(x+4)

Answers

X would equal 14
Hope this helps

Answer:

Step-by-step explanation:

I'm just going to reverse the equation because I'm more comfortable with the x being on the left side:

25(x+4) = 350

Do distributive property (I'll explain down below if you don't know what that is):

25x+100=350

Same to both sides

25x = 250

Divide 25 on both sides

x = 10

Distributive property is when there are multiple terms inside the parenthesis and 1 or more term outside of it

To show this works, lets do 6(5+1)

We can either do 6*6 or we can do 30+6 and we get the same answer

The possible range of the length of side LM is 8 < x < 26A

Step-by-step explanation:

In any triangle:

The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sides

In the given figure

LMN is a triangle

∵ LM = x, MN = 9, NL = 17

→ Find the sum of the lengths of MN and NL

The sum of the lengths of MN and NL = 9 + 17 = 26

→ Find the difference between the lengths of MN and NL

The difference between the lengths of MN and NL = 17 - 9 = 8

→ By using the rules above, x should be between 8 and 26

8 < x < 26

The possible range of the length of side LM is 8 < x < 26

There are 4 female and 4 male kittens are sleeping together in a row. Assuming that the arrangement is a random arrangement, what is the probability that all the female kittens are together, and all the male kittens are together?

Answers

Answer:

I beleive the answer is 8

Step-by-step explanation:

4+4=8

The probability that the female kittens are together, and all the male kittens are together is 1/35.

What is Permutation?

Permutation is defined as the calculation of a set such that it defines the number of ways that something can be arranged.

Let A represents the arrangements of 8 kittens which includes 4 male and 4 female.

N(A) = 8P₈ / (4! × 4!) = 8! / (4! × 4!) = 70

Let B represents the arrangement of kittens such that 4 males are together and 4 females are together.

N(B) = 2

Probability of arranging kittens in such a way that all the female kittens are together, and all the male kittens are together = 2/70 = 1/35

Hence the required probability is 1/35.
