Using proportions, it is found that the percent of decrease in Darnel's daily water consumption was of 0%.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.

One example of application of proportions is for percentage problems, and for the case in this problem, the percent decrease is given by the change divided by the initial amount and multiplied by 100%.

For this problem, we have that:

Hence the percent decrease is found applying the following proportion:

0/100 x 100% = 0%.

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.

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

σ = 8

μ + 1.5σ = 91

μ + 1.5(8) = 91

μ + 12 = 91

μ = 91-12

μ = 79

Therefore, the mean score is 79.

The given expression 1500 x 830 + 321 can be solved as 12,45,321 using arithmetic operations.

Multiplication is the repeated addition of a number. If we multiply m by n, that means m is repeatedly added to itself for n times. The symbol for multiplication is ‘×’.

Addition is the process of combining two or more items (or numbers) to create a new sum.

Given the expression: 1500 x 830 + 321

Using BODMAS, first we do the multiplication.

So, 1500x 830 = 12,45,000

Now, continuing with the addition, we get

12,45,000 + 321 = 12,45,321

Therefore, the given expression can be solved as 12,45,321.

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 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)

   = 9/3

   = 3

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

The number of cloves of garlic you will plant is 288

Given,

There are two groups of garlic bulbs.

Ratio of garlic bulbs = Planting : Cooking = 6 : 1

The number of garlic bulbs used for cooking = 6

The number of cloves in a garlic bulb = 8

We have to find the number of cloves of garlic used for planting:

Here,

Ratio = 6 : 1

1 in ratio represents 6 bulbs of garlic

So, 6 will be, 6 × 6 = 36

That is, the number of garlic bulbs used for planting is 36.

Now,

Number of cloves of garlic used for cooking = 6 × 8 = 48 cloves

Number of cloves of garlic used for planting = 36 × 8 = 288 cloves.

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.

Answer:

for my question u commented on u can just talk about u or anyone for a reference

Step-by-step explanation:

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.
