Madelyn went to the hardware store and bought 7 identical wooden boards. when madelyn placed all the boards end-to-end, the line was 1.9 meters long. to the nearest tenth of a meter, how long was each board?

The equation for the proportional relationship is 16x-y=0 .

The equation of the line passing through the two points (a,b) and (c,d) is given by

(y-b) = m(x-a), where m is the slope .

In the question ,

Given in the graph that

x represents the number of cups of flour and y represents the number of cookies made .

From the graph we can see that

when 6 cups of flower is used , 96 cookies are made

So, the point on the line is (6,96),

when 12 cups of flower is used , 192 cookies are made

So, the point on the line is (12,192)

hence the line passes through the two points (6,96) and (12,192).

So the slope of the line is

m=(192-96)/(12-6)

m= 96/6

m=16

Substituting the values of a,b, c,d and m in the equation of line formula ,we get

y-96=16(x-6)

y-96 = 16x - 96

16x-y=96-96

16x-y=0

Therefore , The equation for the proportional relationship is 16x-y=0.

Division is the process of dividing a bunch of items into equal portions. It is one of the four fundamental operations in mathematics and results in a just distribution of resources. The division of two numbers can be calculated using the following formula: Dividend Divisor = Quotient + Remainder. The number that is being divided in this case is known as the dividend. The number that divides the number (dividend) into equal parts is known as the divisor. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each. The division sign, "÷" or occasionally "/," is used in computer code.

Given Data

The dimensions of the garden are l=20 ft and w=15 ft.

Given, the rectangular garden is 5 ft longer than it's width.

The area of the garden is 300 ft.

dimensions of the garden are = ?

let the width be represented by x.

therefore, length = 5+x

area of the rectangle = l×w

substitute the values.

x(5+x) = 300

5x + x² = 300

x² + 5x - 300 = 0

x²+20x-15x-300 = 0

x(x+20)-15(x+20)=0

(x+20)-(x-15)=0

x=-20 or x=15

hence the dimension cannot be negative.

hence x=15.

substitute x=15 in l=x+5

l=15+5

l=20

Therefore, length and width of the rectangle garden are 20 ft and 15 ft, respectively.

The standard deviation for the test is 8, the mean score is 79.

The standard deviation is a measurement of how much a group of values vary or are dispersed. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Given that,

On a science test, a score of 91 falls exactly 1.5 standard deviations above the mean.

μ + 1.5σ = 91

If the standard deviation for the test is 8

The slope of the line passing through  (4,7) and (7, 16) is 3

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run". It is denoted by "m".

Formula, m = rise / run = (y2 - y1) / (x2 - x1)

Given,

(x1, y1) = (4, 7)

(x2, y2) = (7, 16)

Now, put these values in slope (m) formula,

m = (y2 - y1) / (x2 - x1)

   = (16 -7) / (7 - 4)

Answer:

y = -7

Step-by-step explanation:

If y = 10 when x = 20, then we can find the difference when we do y + 1 = x + 1, which is 11 = 21. Therefore, the difference between x and y is 10. So, we need to do 3-10, which gives us -7.

The value of c would be -32 to get the slope of 8.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given equation is cx + 4y = 12. Convert the equation into the general form of the equation.

cx + 4y = 12

4y = -cx + 12

y = (-c / 4)x + ( 12 / 4 )

y = ( -c / 4) x + 3

The slope of the equation is ( -c / 4 ) which is to be equal to 8.

( -c / 4 ) = 8

c = -32

Therefore, the value of c would be -32 to get the slope of 8.

Is the orange curve.

Here we want to see which one of the graphed curves matches the graph of the quadratic equation:

y = 2x^2 + x

To check that, we can evaluate this curve in some values of x and find some points.

For example, if x = 0 then:

y = 2*0^2 + 0 = 0

So we have the point (0, 0).

Now, if x = 1 then:

y = 2*1^2 + 1 = 2 + 1 = 3

In  quadratic equation  (-11)2 = 121, the solution is actually both x = 11 and x = -11.

What in mathematics is a quadratic equation?

x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:

√x² = √121

x = √121

You might believe that x = 11, but keep in mind that x might also be negative because negative numbers can be squared.

In essence, each real number has both a positive and a negative square root.

Because (-11)2 = 121, the solution is actually both x = 11 and x = -11.

The rule of signs in binomial factors given a trinomial in the form :

Note that b and c can be positive or negative.

And the factor may be :

First thing to do is to check the sign of c.

If it is positive, the signs of m and n can be both positive or both negative.

Since positive multiplied by positive is positive and

negative multiplied by negative is also positive.

If the sign of c is negative, one of the factors must be negative and the other must be positive, because negative multiplied by positive is negative.

After considering the sign of c, next to check is the sign of b.

Case 1 :

If b and c are both positive, we know that the factors can be both negative or both positive.

And since the sign of b is positive, we must follow the sign of it which is positive.

So both m and n are positive

For example :

The factor will be :

which are both positive.

Case 2 :

If b is negative and c is positive, we will follow the sign of b. m and n will be both negative.

For example :

The factors are :

which are both negative

Case 3 :

Now the third case is tricky.

If c is negative, we know that one of m and n is negative and the other one is positive.

The sign of the larger number between m and n will follow the sign of b.

For example :

c is negative, so one factor must be negative and the other must be positive. The sign of b is negative, so the larger factor must be negative also.

The factor will be :

3 is larger than 2, so the negative sign of b will proceed to the factor 3.

Answer:

y=-5x-15

Step-by-step explanation:

Considering the definition of perpendicular line, the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=3/4x-3 is y= -4/3x -1.

A linear equation o line can be expressed in the form y = mx + b

where

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

The line is y= 3/4x - 3. The line has a slope of  3/4.

If you multiply the slopes of two perpendicular lines, you get –1, you get:

3/4× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (3/4)

slope perpendicular line= -4/3

The perpendicular line has a form of: y= -4/3x + b

The line passes through the point (0, -1). Replacing in the expression for perpendicular line:

-1= -4/3×0 + b

-1= 0 + b

-1= b

Finally, the equation of the perpendicular line is y= -4/3x -1 .
