The slope of the line 5y + 3 = (2/5)x is 2 .

The equation of a straight line can be written as follows,

y = mx + c                                         equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is 5y + 3 = (2/5)x .

To get the slope of this given equation we need to convert the given equation in the format of equation of a straight line i.e., equation1.

So, now we will rearrange the given equation as,

 5y + 3 = (2/5)x

⇒ 5y = (2/5)x - 3

Now on dividing this equation by 5 on both sides, we will get

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

On equating equation 1  and equation 2, we will get

Slope of the line = m = 2

Intercept = c = (-3/5)

The given statement exists true. If the measures of the base angles of an isosceles triangle are integers, then the sum of those angles is 2 times that integer, so the sum is an even number. The three angles added together must add to 180.

An isosceles triangle in geometry is one with at least two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

The characteristics of an isosceles triangle are as follows: There is an agreement between two sides. The base of an isosceles triangle refers to the third side of the triangle, which is unequal to the other two sides. The two angles that are opposite the equal sides line up perfectly.

If the measures of the base angles of an isosceles triangle are integers, then the sum of those angles is 2 times that integer, so the sum is an even number. The three angles added together must add to 180.

An even number plus an odd number will be an odd number, and 180 exists always even.

The equation be I = √W/R  

Where I is the current.

W stands for electrical power.

R stands for resistance in ohms then the value of I = 0.5.

A circuit's ability to transport electrical energy is referred to as its electric power. One joule per second, or one watt, is the SI unit of power. Similar to other SI units, watts have standard suffixes that refer to thousands, millions, and billions of watts as kilowatts, megawatts, and gigawatts, respectively.

Let the equation be I = √W/R

Where, I is the current.

W stands for electrical power.

R stands for resistance in ohms.

Simply enter the values of W and R into the equation, i.e.,

When W = 50, R = 200, to solve for the value of I for each set.

I = √50/ 200

The square root of I = √0.25

W = 50, R = 200, I = 0.5.

I = √50/ 200

Answer: Scale factor = 5/4 and this is a fraction number.

Step-by-step explanation:

Given Data,

find the question in the attachment.

Scale factor = (Dimensions of image) / (corresponding dimensions of preimage)

Let us assume,

         Dimensions of image = B

       corresponding dimensions of preimage = A

So,

we can write,

             Length of rectangle B = 45/2

             Length of rectangle A =18

Then,

                Scale factor = B/A

                                     = (45/2) / (18)

                                     =  22.5 / 18

                                     = 5/4

                                     = 1.25

Therefore, image rectangle A is dilated with by a scale factor of  1.25

In order to express 1.25 as a fraction, we will first try to remove the decimal.

As 1.25 has 2 numbers after the decimal point, we will divide it by 100 in order to remove the decimal.

Hence, we get: 1.25 = 125/100

Now, dividing both sides by a common factor of 25, we will get:

125/100 = 5/4

Thus, 1.25 a as a fraction is 5/4.

Therefore,

Scale factor = 5/4 and this is a fraction number.

The property of real numbers illustrated by the equation is commutative property of multiplication.

The basic properties of real numbers are used to determine the sequence of simplifying mathematical expressions.

Commutative property of multiplication states that change order of factors does not change the product. i.e. a*b=b*a.

In the given equation, to determine if the property is applicable, we need to rewrite the equation:

97(7)=100(7)-3(7)

Taking the common factor out on the right side:

97(7)=7(100-3)

Simplifying,

97(7)=7(97)

Both sides of the equation will give the same answer of 679.

Hence, in this form it is evident that commutative property of multiplication is illustrated by the equation 97(7)=100(7)-3(7)

average = [tex]\frac{sum}{count}[/tex]

given her average for 4 subjects is 80 , then

[tex]\frac{sum}{4}[/tex] = 80 ( multiply both sides by 4 to clear the fraction )

sum = 320

let x be the score required to raise average to 84 , then

[tex]\frac{320+x}{5}[/tex] = 84 ( multiply both sides by 5 )

320 + x = 420 ( subtract 320 from both sides )

x = 100

she requires to score 100 in her fifth subject

Answer: she needs score 100 in the fifth subject.

Step-by-step explanation:

Let a subject is nₓ

Hence,

[tex]\displaystyle\\\frac{n_1+n_2+n_3+n_4}{4} =80\\[/tex]

Multiply both parts of the equation by 4:

[tex]n_1+n_2+n_3+n_4=(80)(4)\\n_1+n_2+n_3+n_4=320[/tex]

[tex]\displaystyle\\\frac{n_1+n_2+n_3+n_4+n_5}{5}=84[/tex]

The equation for the vertical translation of y=f(x). 4 units up is y=f(x)+4.

Using equations of the form y=f(x), you may be able to modify the graph in various ways. For example, you can move the chart up, down, left, or right, flip it around the x or y-axis, or stretch or shrink it vertically or horizontally. Understanding these transformations makes it easy to graph different functions. Start with a "basic model" and apply a series of modifications/transformations to change it to the desired function.

A point on the graph of y=f(x) has the shape (x,f(x)).

The points on the graph of y=f(x)+4 are of the form (x,f(x)+4).

So, the graph for y=f(x) +4 is the same as the graph for y=f(x) shifted up by 4 units.

The new equation is:

y=f(x)+4

At 2 % annual interest, the amount invested was $ 7,000 and at 5 % annual interest, the amount invested was $ 3,000.

Total amount invested = $ 10, 000

interest earned = $ 290

Let amount invested for 2 % annual interest = x

Let amount invested for 5 % annual interest = 10,000 - x

so, we get that:

2 % x + 5 % (10,000 - x) = 290

0.02 x + 500 - 0.05 x = 290

500 - 0.03 x = 290
