Answer:

y = (-3/5)x - (31/5)

Step-by-step explanation:

3x + 5y = 11

-3x              -3x

------------------------------

5y = -3x + 11

÷5    ÷5    ÷5

-----------------------

y = (-3/5)x + (11/5)

y - y₁ = m(x - x₁)

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

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

y + 5 = (-3/5)x - (6/5)

    -5                 -5

-----------------------------------

y = (-3/5)x - (31/5)

The east distance from town to house is 6.464 miles.

STEP - BY - STEP EXPLANATION

What to find? The east distance from town to house.

To solve;

Let us first make a sketch to get the clearer picture of the problem.

Attach below is the sketch.

Observe that the house is far east of the center of the town= 3miles + x

We need to find the value of x.

Using Pythagoras theorem;

hypotenuse²= adjacent² + opposite²

From the diagram above,

hypotenuse = 4

adjacent=x

opposite=2

Substitute the values into the formula and solve for x.

4² =x² + 2²

16 = x²+4

Subtract 4 from both-side of the equation.

x²=16 - 4

x²=12

Take the square root of both-side of the equation.

x = 3.464

But recall that, the east distance from town to house = 3+ x

Substitute the value of x.

Hence, the east distance from town to house = 3+ 3.464 = 6.464 miles

The simplified expression of (4⁴)⁻¹  is one over four raised to the fourth power

The expression can be simplified as follows:

(4⁴)⁻¹

Therefore, the expression can be simplified using laws of indices.

[tex](a^{c} )^{b} = a^{cb}[/tex]

and

[tex](a^{-b} )^{c} = \frac{1}{a^{bc} }[/tex]

Therefore, using the laws of indices, the expression can be simplified below:

(4⁴)⁻¹  = 4⁻⁴

Hence,

4⁻⁴ = 1 / 4⁴ = (1 / 4)⁴

Hence,

(4⁴)⁻¹  = 1 / 4⁴ = (1 / 4)⁴

Answer:

C. y = −x + 8

Step-by-step explanation:

Use point-slope form:    y − b = m(x − a) where (a,b) is a point on the line

To do this, first identify the slope of the line from the given equation because having the same slope as the given equation is what makes the constructed line parallel to it.

m = −1

Then use the point (3,5) to construct an equation using point-slope form.

y − 5 = −1(x − 3)

Distribute:

y − 5 = −x + 3

and isolate y.

y = −x + 8

So the answer is C, y = −x + 8.

Answer:

Four Students have failing grades, with a remainder of 4.

28:4 R:4

Step-by-step explanation:

With 32 students in the class. A 7:1 ratio doesn't work perfectly. 7*4=28. 28:4.

32 students - 28 possible students to fail = 4 Remainder since 7:1 ratio doesn't fulfill 32 students.

Since line YZ is parallel to chord line WX and the length of WX is 50, then the length of XZ must be half of WX, which is  A) 25.

Parallel refers to the concept of running multiple processes at the same time. It is often used in computing and engineering to describe the process of running multiple operations simultaneously. It is also used to refer to multiple paths of data or information travelling in the same direction, such as in a computer network. Parallel computing is a form of computation in which multiple processes are run concurrently, either on the same computer or across multiple computers. This allows for faster execution of tasks and better utilization of resources, such as processors and memory.

Since diameter line YZ is parallel to chord line WX, we can use the property of parallel lines that the opposite angles are equal. Thus, we have:

angle ZWX = angle ZYX (corresponding angles)

angle ZYX = 90 degrees (as YZ is a diameter)

angle ZWX = 90 degrees (as WZ is a chord of the circle)

Therefore, triangle WZX is a right triangle with right angle at Z. Using the Pythagorean theorem, we can find the length of XZ as:

[tex]XZ^2 = WX^2 - WZ^2[/tex]

[tex]XZ^2 = 50^2 - (YZ/2)^2[/tex] (as YZ is the diameter and WZ = YZ/2)

[tex]XZ^2 = 2500 - YZ^2/4[/tex]

[tex]XZ^2 = 2500 - (XZ^2/4)[/tex](as YZ = 2XZ)

[tex]5XZ^2/4[/tex] [tex]= 2500[/tex]

[tex]XZ^2 = 2000[/tex]

[tex]XZ = (2000) = 20(5)[/tex]

Therefore, the length of XZ is approximately 44.72 units, which is not one of the answer choices. However, if we assume that the diameter YZ is 100 units (so that WZ = 50 units), then [tex]XZ^2 = 50^2 - 25^2 = 1875[/tex], and [tex]XZ = (1875) = 25(3)[/tex]. This value is approximately 43.30 units, which is closest to answer choice (A) 25. Therefore, the answer is (A) 25.

all the statements prove that a line is parallel to b.

If two non-vertical lines in the same plane have the same slope, they are said to be parallel. Never will two parallel lines cross. If two non-vertical lines in the same plane cross at a right angle, they are said to be perpendicular.

Lines can either be parallel or intersecting. When two lines meet at a point in a plane, they are known as intersecting lines. If a line intersects two or more lines at distinct points then it is known as a transversal line.

line intersects lines a and b at points P and Q respectively. The line l is the transversal here.

∠1,∠2,∠7 and ∠8 are the exterior angles and ∠3,∠4,∠5 and ∠6 denote the interior angles.

The angle pairs formed due to intersection by a transversal are named as follows:

Corresponding Angles: ∠1 and ∠6; ∠4 and ∠8; ∠2 and ∠5; ∠3 and ∠7 are the corresponding pair of angles.

Alternate Interior Angles: ∠4 and ∠5 ; ∠3 and ∠6 denote the pair of alternate interior angles.

Sandra has 1/4 of a roll of ribbon

To make 3 bows, she will use the amount of ribbon shown below:

line A and line B are showing that object A and B are moving with a different rate.

they both are moving with constant speed but we can see that line A has a large slope as compare to line B, that means object A has more speed than the object B.

so the speed of object A is greater than the object B.

Option C. The way that the change would affect the mean and the median is that The mean will increase and the median will not change.

We will find the mean and the median before the 40 was added and after it was added

Before it was added

Mean = 16 + 18 + 20 + 24 + 24 + 24 + 24 + 31 + 32 / 9

= 213 / 9

= 23.67

The median is 24

After we have added 40 the mean would be

16 + 18 + 20 + 24 + 24 + 24 + 24 + 31 + 32 + 40 / 10

= 253 / 10

= 25.3

The median would be 24 + 24 / 2

= 48 / 2

= 24

Hence we can see that the mean got to be higher while the median still remained as 24.

The solution is C.

She uses 800 mL of solution A; that is, 2% of those 800 mL is alcohol

Alcohol on a:

2% of 800 = 2*800/100 = 16mL

If we use x mL of b, the amount of alcohol is:

5% of x = 5*x/100 = x / 20

Total amount of alcohol: 16 + x/20

Total amount of solution mixture: 800 + x

The ratio:

(16 + x/20) / (800 + x) = 3%

(16 + x/20) / (800 + x) = 3/100

1600 + 5x = 2400 + 3x

Solving for x:

5x - 3x = 2400 - 1600

2x = 800

• The vertices of Figure A' are: (1,-4), (10,-3) and (10,-6)

If Figure A is translated 1 unit to the left, the vertices are:

Next, a rotation of 180° counterclockwise about the origin gives:

These are the vertices of Figure A'.

Thus, the correct transformation is: translated 1 unit to left and then rotated 180° counterclockwise about the origin.

The correct choice is C.

By solving a system of equations we can see that Olivia spent $14 and Camiller spent $37.

Let's define two variables:

We know that " Camille spent $14 less than three times what Olivia spent" so we can write:

y = 3*x - 14

And "In total, they spent $54"

x + y = 54

Then we have a system of equations:

y = 3*x - 14

x + y = 54

Replacing the first equation into the second one, we get:

x + 3x- 14 = 54

4x - 14 = 54

4x = 54 + 14

4x = 68

x = 68/4 = 17

Now that we know the value of x, we can try to find the value of y.

y = 3x - 14 = 3*17 - 14 = 37

So Olivia spent $14 and Camiller spent $37.

The answer is:

The greatest common factor is 1

Answer:

x=4/15

Step-by-step explanation:

first you need to make common denominators for 1/5 and 1/3

the common denominator is 15

5*3=15, 3*5=15. 1*3=3, 1*5=5

new equation:3x-3/15=x+5/15

now subtract x from both sides: 3x-3/15=x+5/15

                                                     -x          -x

                                                     2x-3/15=5/15

now you can add 3/15 to 5/15

2x=8/15

now for the last step, divide by 2 because there are 2 x's

2x/2=x         8/15 /2=4/15

x=4/15

Answer:

4/15

Step-by-step explanation:

3x-1/5 = x+1/3

make a common denominator

3x -3/15 = x + 5/15

next you can take away one x from both sides

2x - 3/15 = 5/15

then we want to have x alone on one side and everything else on the other

2x = 5/15 + 3/15

2x = 8/15

1x = 8/15 ÷ 2

1x = 8/30

simplify that

x = 4/15
