Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

-x + 5y = -4

4x + 3y = 16

Step 2: Rewrite systems

x = 5y + 4

4x + 3y = 16

Step 3: Solve for y

Substitute in x:                              4(5y + 4) + 3y = 16Distribute 4:                                   20y + 16 + 3y = 16Combine like terms:                     23y + 16 = 16Subtract 16 on both sides:           23y = 0Divide 23 on both sides:              y = 0

Step 4: Solve for x

Define:                              4x + 3y = 16Substitute in y:                 4x + 3(0) = 16Multiply:                            4x = 16Isolate x:                            x = 4

And we have our final answer!

-
A. arithmetic
B. geometric
C. neither
D. not enough information

Answers

the answer is arithmetic

It is a geometric series.

The ratio of the second to first term is= [tex]\frac{4}{10}=\frac{2}{5}[/tex]

The ratio of the third to second term is= [tex]\frac{\left(\frac{8}{5}\right)}{4}=\frac{2}{5}[/tex]

The ratio of the fourth to third term is=[tex]\frac{\left(\frac{16}{25}\right)}{\left(\frac{8}{5}\right)}=\frac{2}{5}[/tex]

Since the common ratios are same so it is a geometric series.

Which point could be removed in order to make the relation a function?
{(-4,3), (-5, 6), (1, 0),(-4,5), (9,5), (0, -7)}

Answers

Answer:

Either (-4, 3) or (-4, 5).

Step-by-step explanation:

A function is a relation when each input has exactly one output. The inputs must not repeat in a function.

In the relation given, the input '-4' repeats.

{(-4,3), (-5, 6), (1, 0),(-4,5), (9,5), (0, -7)}

If we remove either (-4, 3) or (-4, 5), it would make the relation a function.

List the first 4 terms of a geometric sequence with a first term of 2 and a common ratio of 5.
I have no clue even where to start. The question after that is the same, except the first term is 4 and the common ratio is 4.

Answers

Answer:

pohujnkmhugyfdtr

Step-by-step explanation:

The first 4 terms of the geometric sequence with a first term of 2 and a common ratio of 5 are 2, 10, 50, 250

using the geometric sequence formula,

aₙ = arⁿ⁻¹

where

a = first term = 2

r = common ratio  = 5

let find the remaining 3 terms

The 2nd term can be found below

a₂ = 2 × 5²⁻¹ = 2 × 5 = 10

The 3rd term can be found below

a₃ = 2 × 5³⁻¹ = 2 × 25 = 50

The 4th term can be found as follows

aₙ = 2 × 5⁴⁻¹ = 2 × 125 = 250

Therefore, the first 4 terms are 2, 10, 50, 250.

Step: Solve6x+y=−21for y:

6x+y=−21

6x+y+−6x=−21+−6x(Add -6x to both sides)

y=−6x−21

Step: Substitute−6x−21foryin8x−3y=36:

8x−3y=36

8x−3(−6x−21)=36

26x+63=36(Simplify both sides of the equation)

Find the sine of J. Write your answer in rationalized form

Answers

Answer:

[tex]sin\:(J)\:=\:\frac{4\sqrt{5}}{7\sqrt{2}}[/tex]          

Step-by-step explanation:

As we know that

sinФ = opposite ÷ hypotenuse

Given the triangle with

Ф = JThe opposite of j is [tex]4\sqrt{5}[/tex]

The length of the hypotenuse of a right triangle can be calculated as:

[tex]c=\sqrt{a^2+b^2}[/tex]

[tex]c=\sqrt{\left(3\sqrt{2}\right)^2+\left(4\sqrt{5}\right)^2}[/tex]

[tex]c=\sqrt{3^2\cdot \:2+4^2\cdot \:5}[/tex]

[tex]c=\sqrt{18+80}[/tex]

[tex]c=\sqrt{98}[/tex]

[tex]c=\sqrt{7^2\cdot \:2}[/tex]

[tex]c=\sqrt{2}\sqrt{7^2}[/tex]

[tex]c=7\sqrt{2}[/tex]

so

sinФ = opposite ÷ hypotenuse

substituting the values Ф = J, opposite = [tex]\sqrt{5}[/tex], hypotenuse = [tex]c=7\sqrt{2}[/tex]

[tex]sin\:(J)\:=\:\frac{4\sqrt{5}}{7\sqrt{2}}[/tex]          

Therefore,

[tex]sin\:(J)\:=\:\frac{4\sqrt{5}}{7\sqrt{2}}[/tex]
