Step-by-step explanation: You just subtract the 2 from the 5 because the denominators are the same. You subtract because there is one subtraction sign and one addition sign.

The slope-intercept form of the equation of the line described is y = -6x/5 + 7/5.

Given the following data:

Points on x-axis = (-3, 2).

Points on y-axis = (5, -1).

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope, m = (-1 - 5)/2 + 3)

Slope, m = -6/5

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

At point (2, -1), we have:

-1 = -6/5(2) + c

-1 = -12/5 + c

c = 12/5 - 1

c = 7/5

In conclusion, we can reasonably and logically deduce that the slope-intercept form of the equation of the line described is y = -6x/5 + 7/5.

The change received by Chloe after paying a $20 bill for ribbons is $3.2.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given is the table that represents the cost per yards of the ribbons.

From the question, we can write -

Ribbon       Cost per Yard ($)

Chiffon                 5.88

Satin                     1.50

Lace                     3.29

Tulle                     2.25

Cost of one yard of satin ribbon → $1.50.

Then, the cost of 5.5 yards of satin ribbon [A1] → 5.5 x 1.50 = $8.25.

Cost of one yard of tulle ribbon → $2.25.

Then, the cost of 3.8 yards of tulle ribbon [A2] → 3.8 x 2.25 = $8.55.

Total cost of both the Ribbons → A1 + A2 = 8.25 + 8.55 = $16.8.

Money paid by Chloe → $20

Change received by Chloe → 20 - 16.8 = $3.2

Therefore, the change received by Chloe after paying a $20 bill for ribbons is $3.2.

Answer:

  (x +3)² +(y -4)² = 9

Step-by-step explanation:

You want the equation of a circle with center (-3, 4) and radius 3.

The equation of a circle with center (h, k) and radius r is ...

  (x -h)² +(y -k)² = r²

You have a circle with center (h, k) = (-3, 4) and radius r = 3. Using these values in the above equation, we find the circle equation to be ...

  (x -(-3))² +(y -4)² = 3²

  (x +3)² +(y -4)² = 9

In linear equation, there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds.

What are a definition and an example of a linear equation?

Let the number of 250g=0.25  kg jars be x and that of 500g=0.5 kg jams be y;

therefore:

total number of jars was

x+y=511

x=511-y..........i

total amount kg was:

0.25x+0.5y=186.5....ii

substituting i in ii

0.25(511-y)+0.5y=186.5

127.75-0.25y+0.5y=186.5

solving for y we get:

0.25y=186.5-127.75

0.25y=58.75

y=58.75/0.25

y=235 jars

and

x=511-x

=511-235

=276

hence , there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds.

The value of logarithmic expression log s√7/t² is log (7/t²)^1/s.

By considering the given  logarithmic expression

log s√7/t²

=log (7/t²)^1/s

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

[tex] C_{1} V_{1} + C_{2} V_{2} = C_{final}V_{final}[/tex]

Let the [tex] V_{2}[/tex] be x. So, final volume will be (18 + x).

Keep the values in formula to find the value of volume of solution required for dilution -

8%×18 + 4.5%×x = 6%×(18 + x)

Rewriting the equation -

0.08×18 + 0.045×x = 0.06(18 + x)

Performing multiplication to find the value of x -

1.44 + 0.045x = 1.08 + 0.06x

Rewriting the equation -

1.44 - 1.08 = 0.06x - 0.045x

Performing subtraction on both sides of the equation -

0.37 = 0.015x

Shifting 0.015 to other side fo equation and performing division

50 would be the largest count of fishes that would be in the tanker.

This is because of divide rule.

If the owner wants to keep the equal number of fishes in the tanker, he have to divide the total number of fishes by total number of tankers.

so,

= [tex]\frac{1423}{29}[/tex]

= 49.

It implies that 27 tankers would have 49 fishes in each of them and rest 2 tankers will adjust the remaining extra 2 fishes in themselves , so they would accommodate 50 fishes in each of them.

As the name implies, division rules in mathematics allow one to determine if a number may be divided by another number without using the actual division procedure. When two numbers can be divided evenly, the quotient is always a whole number and the remainder is always zero.

In accordance with the rule of seven divisibility, if a number is divisible by seven, then "the difference between twice the unit digit of the provided number and the remaining portion of the given number should be a multiple of seven or it should be equal to zero." 798, for instance, may be divided by 7.

(-2.5 , 0.5)

Step-by-step explanation:

You can use the midpoint formula.

x(sub1) + x(sub2) / 2  ,  y(sub1) + y(sub2) / 2

For example:

-5 + 0 / 2  ,  -2 + 3 / 2

-5 / 2  ,  1 / 2

-2.5 , 0.5

midpoint = (-2.5 , 0.5)

The x-intercept of the function are (√2-1,0) and(-√2-1,0). and the y-intercept of the function is  (0,-1) and the inverse of the function is f⁻¹(x)=±√(x+2)-1.

The x and y intercepts of a function is defined as the points on the cartesian plane where the graph of the function intersects  the co-ordinate axes.

The intercepts are calculated by substituting the value of x and y to zero to calculate the corresponding variable.

The inverse of a function y=g(x) is calculated by finding the value of x from the equation.

At x=0 , we get the y intercept.

f(0)=(0+1)²-2

or, f(0)=-1

So the y-intercept is at (0,-1) .

At y=0 we get the x-intercept.

f(x)=0

or,(x+1)²-2=0

or,(x+1)²=2

or, x+1= ±√2

or, x=±√2-1

Therefore the x-intercepts are (√2-1,0) and(-√2-1,0).

Now let us calculate the inverse of the function.

y=(x+1)²-2

or,y+2=(x+1)²

or, x+1=±√(y+2)

or, x=±√(y+2)-1

Hence the inverse of the function is written as

f⁻¹(x)=±√(x+2)-1
