Answer:

y = 3x + 5

Step-by-step explanation:

The slope-intercept form of a line is [tex]y = mx + b[/tex], where m is the slope, and b is the y-intercept.

To solve for m (the slope), use the formula: [tex]m = \frac{y__{2} - y__{1}}{x__{2} - x__{1}}[/tex], where [tex](x_{1} , y_{1} )[/tex] and [tex](x_{2}, y_{2})[/tex] are the points you are given.

. . . . . . . . m = (17 - 11) / (4-2)

. . . . . . . . m = 6/2

. . . . . . . ∴ m = 3

Substitute the slope, m, into the slope-intercept equation.

y = 3x + b

Now we have to solve for b, the y-intercept. To do so, substitute a point that was given to you into the equation.

I chose the point (4,17), but you can also do (2,11).

. . . . . . . . 17 = 3(4) + b

. . . . . . . . . . remember that the x-variable is being multiplied to the m

. . . . . . . .  -12 + 17 = 12 + b - 12

. . . . . . . .  ∴ 5 = b

Substitute the y-intercept, b, into the slope-intercept equation, and you're done!

[tex]y = 3x + 5[/tex]

It is true that Sarah's maximum heart rate over this twenty-year period will have decreased by approximately 8%.

The percentage decrease is determined by ascertaining the reduction or difference in heart rate at the beginning and at forty.

This difference becomes the numerator of the division operation by the heart rate at the beginning and then multiplied by 100.

Sarah's heart rate at twenty years = 193 beats per minute

Sarah's heart rate at forty years = 178 beats per minute

Difference (Decrease) in heart rate = 15 beats per minute (193 - 178)

Percentage decrease = 7.77% (15/193 x 100)

= 8%

Thus, we can conclude that Sarah's heart rate has decreased by about 8%.

58 is the number which would be much more than 23 is 9*9.

Here,

It is asked that how much more we need to add in 23 to get the value 9*9.

Here, 9*9 means we simply have to multiply 9 with 9 and we will get 81.

so, we know that

     9*9 = 81

Now, we have to find how much we need to substract in 81 to get the value as 23

     81-23 =58

when we deduct 23 from 81 then we get 58.

hence, 58 is the answer.

The unit rate of bananas is $2.25 per pound.

What is the meaning of unit rate?

Unit Rate = Ratio between two separate quantities with different units. = a:b. = a/b. This formula can be used to determine the rate of any two given quantities, such as a and b.

Given that the cost of 2/3 pound of bananas is $1.50.

If the number of pound of bananas increase then the cost of bananas will be increase.

So the relation between amount of banana is directly proportion with the cost.

Therefore,

Amount of bananas/ cost of bananas = Amount of bananas/ cost of bananas

(2/3)/1.50 = 1/x

2/4.50 = 1/x

x = 4.50/2

Answer: bro this ez 1.5 for the first one second should be 22 correct me if im wrong.

Step-by-step explanation:

'4 more than a number' implies that there exists a number which is 4 units greater than the original number, using the concept of addition.

Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (that is, "3 plus 2 is equal to 5").

Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces and subgroups.

Now, let us understand the meaning.

Let the original number be x.

'4 more than a number' implies x + 4.

This means that the new number, x + 4, is greater than the original number, x, by 4 units. We also have to keep in mind, [tex]x + 4 > x[/tex].

Hence, the final meaning is 4 units greater than the original number.

The number of cubes of edge length 1/3 is 27 and the volume of the cube is 1 cubic inches

From the question, we have the following parameters that can be used in our computation:

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube 1 = (1/3 inch)³ = 1/27 cubic inches

Volume of cube 2 = (1 inch)³ = 1 cubic inch

The number of cubes is then calculated as

Number of cubes = Volume of cube 2/Volume of cube 1

This gives

Number of cubes = 1/(1/27)

Number of cubes = 27

Here, we have

Edge length of cube = 1 inch

The volume of a cube is the cube of its edge length

The roots of the quadratic equation x² + 2√3 x + 3 = 0 have only one root and it is -√3

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 2√3 x + 3 = 0   be equation (1)

On factorizing the equation , we get

The roots of the quadratic equations are calculated by

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = [ -2√3 ± √ ( ( 2√3 )² - 4 ( 3 ) ) ] / 2

On simplifying the equation , we get

x = [ -2√3 ± √ ( 12 - 12 ) ] / 2

The discriminant is zero we get just one real solution

So ,

x = [ -2√3 ± √0 ] / 2

x = ( -2√3 ) / 2

x = -√3

Therefore , the value of x is -√3

Hence , the root of the quadratic equation is -√3
