Answer 1

Answer:

y = 4x - 1

Step-by-step explanation:

y = mx + b

Here m is slope and b is y-intercept

What is the solution to this system of equations? Show your work. 46 points

Answers

y - x = 9
12 = 1/3x

The first thing you want to do when solving a system of equations is isolating one of the variables.
Since the second equation only contains x, we can isolate x in the first equation.

y - x = 9
y = x + 9
x = y - 9

You can also solve the second equation without any previous solving.
12 = 1/3x
Multiple both sides by 3/1 or 3
x = 36

Now we can set them equal to each other

36 = y - 9
y = 45

Answer: x = 36 and y = 45

Answer:

The solutions to systems of equations are the variable mappings such that all component equations are satisfied—in other words, the locations at which all of these equations intersect. To solve a system is to find all such common solutions or points of intersection.

Step-by-step explanation:

Isolate x for 12=1/3x: x=36

[y - 36=9]

the solutions to the system of equation is:

y=45 x=36

In AXYZ, ZX=13° and XY=63º. ZXWZ=90° and XY=690. Find the length of XW to
the nearest 10th.

Answers

We want to find WZ, so we focus on right triangle YWZ. Side WY is half the length of XY because WZ is a line bisector of XY. Therefore, YW is 4.25

Now, we have a right triangle with a known angle and a known side. With this type of triangle, we can use basic trigonometry applications.

The side opposite to the 90 degree angle is the hypotenuse. The hypotenuse is YZ. The two legs are WZ and YW.

We can use cosine function to find tangent because the YZ is not known.

tangent is side opposite of angle divided by side adjacent to angle.

tan(72) = WZ / 4.25

4.25tan(72) = WZ

0.3 = WZ

If comparing x^2 to x^3, which value of x gives the greatest difference:x=6,x=8,x=10?

Answers

Answer:

the value of x that gives the greatest difference is 10.

Step-by-step explanation:

Given;

x² and x³

values of x = 6, 8 and 10

When x = 6

6³ - 6² = 216 - 36 = 180

When x = 8

8³ - 8² = 512 - 64 = 448

When x = 10

10³ - 10² = 1000 - 100 = 900

Therefore, the value of x that gives the greatest difference is 10.

Answers

Answer:

[tex]\dfrac{1}{24}[/tex]

Step-by-step explanation:

We need to find the value of 1/4÷6.

It can be done as follows :

[tex]\dfrac{\dfrac{1}{4}}{6}[/tex]

We know that, [tex]\dfrac{\dfrac{1}{x}}{y}=\dfrac{1}{xy}[/tex]

We have, x = 4 and y = 6

So,

[tex]\dfrac{\dfrac{1}{4}}{6}=\dfrac{1}{4\times 6}\\\\=\dfrac{1}{24}[/tex]

So, the final answer is equal to [tex]\dfrac{1}{24}[/tex].

decide if the two statements are logically equivalent statements, negations or neither ​

Answers

Answer:

Negations.

Step-by-step explanation:

The first statement is:

p ∧ q

(p and q)

This statement is only true when:

p = true

and

q = true.

And is false in all the other cases.

The other statement is:

¬q ∨ ¬p

(not q or not p)

This statement is only true if at least one of the elements is true, this happens if:

q =false (then ¬q = true)

or

p = false (then ¬p = true)

Then the first statement needs p and q to be true.

The second statement needs at least one of these to be false.

This means that when the first statement is true, the second statement is false.

When the first statement is false, the second one is true.

Then the statements are negations.

Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

Answers

Answer:

I = $ 6.00

Step-by-step explanation:

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 60 × 0.1 × 1 = 6

I = $ 6.00

The simple interest accumulated

on a principal of $ 60.00

at a rate of 10% per year

for 1 years is $ 6.00.

What is the quotient when (x+ 2) is divided into the polynomial 2x2 - 2x - 12?
O A. 2x-5 with no remainder
O B. X+ 3 with a remainder of -2
O C. 2x-3 with a remainder of 5
O D. 2x-6 with no remainder

Answers

Answer:

2x² - 2x - 12 ÷ (x+2)

= 2x - 6

D. 2x-6 with no remainder

The quotient when (x + 2) is divided into the polynomial 2x² - 2x - 12 is, (2x - 6) with no remainder.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

To find the quotient when (x + 2) is divided into the polynomial

2x² - 2x - 12.

Now,

The polynomial is,

⇒ 2x² - 2x - 12

⇒ 2 (x² - x - 6)

⇒ 2 (x² - 3x + 2x - 6)

⇒ 2 [ x (x - 3) + 2(x - 3) ]

⇒ 2 [ (x + 2) (x - 3) ]

Hence, We can divide polynomial by (x + 2) as;

⇒ 2 [ (x + 2) (x - 3) ] ÷ (x + 2)

⇒ 2 (x - 3)

⇒ 2x - 6

Therefore, the quotient when (x + 2) is divided into the polynomial

2x² - 2x - 12 is, (2x - 6) with no remainder.

A line that includes the points (9,j) and (10,4) has a slope of 1. What is the value of j?

Answers

Answer:

soln

A=(9,j)

x1=9,y1=j

B=(10,4)

x2=10,y2=4

slope=1

by using the fomulaof slope,

slope=y2-y1/x2-x1

1 =4-j/10-9

1 = 4-j/1

1=4-j

j=4-1

j=3

Answer:

j = 3

Step-by-step explanation:

(9 , j) ; [tex]x_{1}= 9[/tex]   and [tex]y_{1} = j[/tex]

(10, 4) ; [tex]x_{2} = 10[/tex]   and [tex]y_{2} = 4\\\\[/tex]

[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\ \frac{4 - j}{10-9} = 1\\\\\frac{4 - j}{1}=1[/tex]

4 - j = 1   {Subtract 4 from both sides}

-j = 1 -4

-j = -3 {Multiply both sides by (-1) }

j = 3
