Answer:

y=-1

x=2

Step-by-step explanation:

5x-4y=14 multiply by 4

4x+7y=1 multiply by 5

20x-16y=56

20x+35y=5 eliminate by subtracting

-51y=51

y=-1

plug back in to get x

4x+7(-1)=1

x= 2

Answer:

x = 5

Step-by-step explanation:

Given

x + 5 = 10 ( isolate x by subtracting 5 from both sides )

x = 5

The required simplified value of the expression is 6.

Given that,
An expression is given 4+(9x2)÷(4-1)-4,
To simplify the given expression.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

In mathematics, it deals with numbers of operations according to the statements.

⇒ simplification
= 4+(9x2)÷(4-1)-4
Step 1 applies to the multiply and subtraction operation in the parenthesis.|
= 4 + (18) ÷ (3) - 4
Step 2 following the PEMDAS rule division of 18 by 3,
= 4 + 6 - 4
Step 3 association of termes,

Answer:

Step-by-step explanation:

The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000

Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.

So, the number 10,000 which is the square of 100 has 4 zeros.

The answer would be -7/12

Step-by-step explanation:

What you would do is

a/b×c/d=ac/bd

this would be the formula

so what you would do is -7 (which is the numerator X the other numerator which equals -7 times 1= -7

then you would do 2 X6= which is 12 so the answer would be 7/12 because you can't simplify it anymore

Answer: f(x) · g(x)=-32x³+104x²-100x+100

Step-by-step explanation:

Since we are given f(x) and g(x), all we have to do is multiply them together.

f(x) · g(x)=(4x-10)(-8x²+6x-10)                              [distribute by FOIL]

f(x) · g(x)=-32x³+24x²-40x+80x²-60x+100         [combine like terms]

f(x) · g(x)=-32x³+104x²-100x+100

Now, we have multiplied them together, we have f(x) · g(x)=-32x³+104x²-100x+100.

Answer:

The area of the square being 81 sq m, each side will be 81^0.5 = 9 m. The perimeter is thus 4 times the side = 4*9 = 36 m. The sides of the square are the square root of the area (81m^2), which is 9m.

Answer:

you figure it out

Step-by-step explanation:

Number one is going to be N1

Number two is going to be N2

Product of the two numbers combined is going to be 891

N1= N2 +5

N1 + N2 = 891

(N2+5) + N2 = 891

N2 +5 +N2 =891

2N2 + 5 =891

Answer:

(A) The mean temperature for the second week is 4.86 degrees Celsius.

(B) The mean absolute deviation for the second week is 4.86 degrees Celsius.

(C) The second week had greater variability in high temperature.

Step-by-step explanation:

We are given that the daily high temperatures, in degrees Celsius, for two weeks were recorded. The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius.

Here is a list of the high temperatures, in degrees Celsius, for the second week;

5, 9, 7, 0, 3, 5, 5

(A) The mean temperature for the second week is given by;

                  Mean = [tex]\frac{\text{Sum of all data values}}{\text{Total number of values}}[/tex]

                             = [tex]\frac{5+9+7+0+3+5+5}{7}[/tex]

                             = [tex]\frac{34}{7}[/tex] = 4.86 degrees Celsius

(B) Mean absolute deviation for the second week is calculated as;

Firstly, subtracting mean from each data value;

| 5 - 4.86 | = 0.14

| 9 - 4.86 | = 4.14

| 7 - 4.86 | = 2.14

| 0 - 4.86 | = 4.86

| 3 - 4.86 | = 1.86

| 5 - 4.86 | = 0.14

| 5 - 4.86 | = 0.14

Now, we will find the mean of these deviations;

Mean absolute deviation = [tex]\frac{0.14+4.14 + 2.14+4.86+1.86+0.14+0.14}{7}[/tex]

                                          = [tex]\frac{13.42}{7}[/tex] = 1.92 degrees Celsius

(C) The second week had greater variability in high temperature because it's mean absolute deviation is greater than that of first week. And also the mean absolute deviation tells us that on average how far the data values are from the mean.

Answer:

Hence, the watcg must be bought at rupees 4888

Step-by-step explanation:

Let the desired selling price of the watch be x

Cost Price of the watch = 4444

We know that if Cost Price < Selling Price,

Selling Price - Cost Price = gain

When we substitute we get,

x-4444=444

x= 4888

Answer:

[tex]2018 \times (|\frac{1}{2017} - \frac{1}{2016} | + |\frac{1}{2018} - \frac{1}{2017}| - |\frac{1}{2018} - \frac{1}{2016}|)[/tex]

1/2017 is smaller than 1/2016. 1/2018 is smaller than 1/2017. And 1/2018 is smaller than 1/2016. So we can rewrite this as:

[tex]2018 \times ((\frac{1}{2016} - \frac{1}{2017} ) + (\frac{1}{2017} - \frac{1}{2018}) - (\frac{1}{2016} - \frac{1}{2018}))[/tex]

Distribute:

[tex]2018 \times (\frac{1}{2016} - \frac{1}{2017} + \frac{1}{2017} - \frac{1}{2018} - \frac{1}{2016} + \frac{1}{2018})[/tex]
