The value of a for system ax + 12y = −6, 2x − 6y = 4 having no solution is a = -4.

Equation: A statement that two variable or integer expressions are equal. In essence, equations are questions, and the motivation for the development of mathematics has been the systematic search for the answers to these questions.

Given:

ax + 12y = −6

2x − 6y = 4

Calculate the value of a by using the condition of no solution of the system given below,

[tex]a_1 / a_2 = b_1 / b_2 \neq c_1/c_2[/tex]

So, a₁ / a₂ = b₁ / b₂

a / 2 = 12 / (-6)

a / 2 =  - 2

a = -4

And -4 / 2 ≠ -6 / 4

Therefore, the value of a for system ax + 12y = −6, 2x − 6y = 4 having no solution is a = -4.

Answer:

122.5

Step-by-step explanation:

first you divide 70/4 =17.5 then you multiply 17.5 by 7 and get 122.5

Based on the given rate, which is  4-ounce serving of applesauce has 70 Calories the Calorie level of 7 ounces of applesauce is 122.5 calories

The number of calories in 7 ounces of applesauce is solved by comparing the how many 4 ounce is in 7 ounce

The amount of 4 ounce in 7 ounce = 7 ounce / 4 ounce

The amount of 4 ounce in 7 ounce = 1.75 ounce

Then the equivalent amount of calories is solved by multiplication

Hello,

The slope-intercept form of a linear equation is:

y = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To write the equation of the line with slope m = -1 that passes through the point (4, 5), you can use the point-slope form of a linear equation, which is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope of the line. Plugging in the values, we get:

y - 5 = -1(x - 4)

This simplifies to:

y - 5 = -x + 4

Finally, we can rearrange the terms to put the equation in slope-intercept form:

y = -x + 9

This is the equation of the line with slope m = -1 that passes through the point (4, 5).

Answer:

Length (L) = 50 m

Step-by-step explanation:

Given information,

→ 400 m long fencing wire is required to surround square flower garden 2 times.

Now the fence taken for 1 time,

→ 400 ÷ 2

→ 200 m

Formula we use,

→ P = 4 × L

[Perimeter of square]

Then the length of the garden is,

→ P = 4 × L

→ 200 = 4L

→ 4L = 200

→ L = 200/4

→ [ L = 50 m ]

Hence, length of garden is 50 m.

One hose can fill a small swimming pool in 75 minutes. Two hoses will fill the pool in 30 minutes when working together.

Given, the volume ( the space occupied by an solid object)  per minute

Smaller hose fills  the pool in 75 minutes. (1/75)

A larger one can fill the pool in 50 minutes. (1/50)

So, together they will fill = (1/ 75 ) + (1/50) , the lcm of 75 and 50 is 150

                                            =  (2/150) + (3/150)  

                                            =  5/150

                                            = 1/30 or 30 minutes

The following complex number (1-i)³ in a+ bi form is -2+4i

In mathematics, a complex number is a part of a number system that includes an element with the symbol I often known as the imaginary unit, and extends the real numbers. Complex numbers satisfy the equation that any complex number can be represented as a + bi, where a and b are real numbers. Rene Descartes referred to me as an imaginary number because no real number can satisfy the aforementioned equation. A and b are referred to as the real and imaginary parts, respectively, of the complex number a+bi. Complex numbers are accepted in the mathematical sciences as being just as "real" as real numbers despite the historical appellation "imaginary."

(1-i)³

=1³-i³-3(1)(i)(1-i)

=1+i-3(1-i)

WXYZ to JKLM

JM is equal to 9, ZW is 13.5, JK is 12, and WX is 18.

To obtain the coordinates of the other shape, multiply the original shape by the scale factor

What is the scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.

13.5 / 9 = 1.5

9 * 1.5 = 13.5 \s12 * 1.5 = 18

You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)

JKLM ~ WXYZ

So  JK ~  WX

So the scale factor  =  WX / JK

Scale Factor   =  18 / 12 =   3 / 2    =   1.5

The confidence interval gets broader as the confidence level rises because the error bound rises as well. The confidence interval gets narrower as the confidence level is reduced since the error bound is also reduced.

This can be the reason why  you might want to increase the confidence level, even though it means that precision is lost and the interval widens.

We must widen the distance in order to obtain greater trust. The multiplier, which rises with confidence level, shows this clearly. The width of confidence intervals will rise when sample size is increased.

An unknown population parameter's likely range of values is known as a confidence interval. A certain proportion of the confidence intervals will include the population mean if you repeatedly take random samples. The confidence level is expressed as this percentage.

Answer: No

A correlation is a relationship between two variables that tend to move in the same direction. Therefore, a positive correlation will describe two variables that increase together. However, correlation does not always equal causation, and in this case, this conclusion cannot be made. A more probable explanation is that there is some third variable causing an increase in population, so more people are buying more cars, not the other way around.

A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16, RT= 32  and UV ≈ 8.2.

A diagram is provided, on which R S T U's perimeter is 72 and R V's is 16.

Finding R T and U V is our goal.

First, let's assume that the figure RSTU is a rhombus since its perimeter and one-half of a diagonal's length are both provided. RT is the result of adding the segments RV and VT.

RT=RV + VT

We are informed that the RV is sixteen. If RV and VT are congruent, then V T equals 16. So:

R T = 16 + 16 = 32

In order to determine the UV length, we must first determine the RU length. Since a rhombus's sides are the same length, we can divide its perimeter by four to determine

RU= Perimeter/ 4

If we simplify and replace Perimeter with 72, we get:

RU = 72 / 4

RU =18

Since UB is a member of the right triangle RUV created by the intersection of the diagonals, we can now use the Pythagorean theorem to determine its length. So:

U V²+ R V² =  RU²

If R V = 16 and R U = 18, we obtain:

U V² + 16 ²= 18²

By way of summary, we have:

U V² + 256 = 324

U V² + 256 − 256 = 324 − 256

√ UV = √ 68

UV = 8.2462

UV ≈ 8.2

Our recommendations are as follows:

RT= 32

UV ≈ 8.2.
