Answer:

5x-(-4x-6) = 10

Step-by-step explanation:

Given the expression

y=−4x−6 ..... 1

5x−y=10... 2

To get the required equation we will substitute equation 1 into 2

5x-y = 10

5x-(-4x-6) = 10

5x+4x+6 = 10

9x+6 = 10

9x = 4

x = 4/9the required equation is 5x-(-4x-6) = 10

Answer:

5x - (-4x - 6) = 6

Step-by-step explanation:

Sandy has 15 roses, 5 daises and 10 tulips

She wants to arrange the flower in such a way that each bouquet will have the same flower in it

Therefore the greatest number of flowers that will be in each bouquet is 5 flowers this is so inorder to make each bouquet contain equal number of flowers, this means that one bouquet must not be greater than the other.

Answer:

For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.

Step-by-step explanation:

We all know, the Pythagorean theorem can be stated as follows:

The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.

i.e.

[tex]a^2+b^2=c^2[/tex]

Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.

Given that:

[tex]a[/tex] and [tex]b[/tex] are rational numbers.

To find:

Situation for which [tex]c[/tex] is irrational.

Square of a rational number is always rational.

So, [tex]a^{2} , b^{2}[/tex] both will be rational.

And sum of squares of two rational numbers will also be rational.

Therefore, [tex]a^2+b^2[/tex] will also be rational.

and

[tex]c = \sqrt{a^2+b^2}[/tex]

For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.

Step-by-step explanation:

The word together symbolizes that we are adding.

We add the numerators but keep the denominator the same since it is already the same.

1+3 is 4, so that is our new numerator.

Answer:

The domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].

Step-by-step explanation:

Let [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex], which is rearranged by algebraic means:

1) [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex]  Given

2) [tex]f(5\cdot x) = \frac{x\cdot 1 - 5}{5\cdot x -1}[/tex] Modulative property

3) [tex]f(5\cdot x) = \frac{5^{-1}\cdot (5\cdot x)-5}{5\cdot x -1}[/tex] Existence of multiplicative inverse/Associative and commutative properties.

4) [tex]f(x) = \frac{5^{-1}\cdot x - 5}{x-1}[/tex] Composition of functions.

5) [tex]f(x) = \frac{(5^{-1}\cdot x-5)\cdot (5\cdot 5^{-1})}{x-1}[/tex] Existence of multiplicative inverse/Associative property.

6) [tex]f(x) = \frac{(x-25)\cdot 5^{-1}}{x-1}[/tex]  Commutative, associative and distributive properties/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction

7) [tex]f(x) = (x-25)\cdot [5^{-1}\cdot (x-1)^{-1}][/tex] Definition of division/Associative property

8) [tex]f(x) = (x-25)\cdot (5\cdot x -5)^{-1}[/tex]  [tex]a^{c}\cdot b^{c} = (a\cdot b)^{c}[/tex]/Distributive property/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction

9) [tex]f(x) = \frac{x-25}{5\cdot x - 5}[/tex] Definition of division/Result

The domain of a polynomial-based rational function consists in all values of the real set except values where denominator equals zero. The value of [tex]x[/tex] such that rational function becomes undefined is:

1) [tex]5\cdot x - 5 = 0[/tex]  Given

2) [tex]5\cdot (x-1) = 0[/tex] Distributive property

3) [tex][5\cdot (x-1)]\cdot 5^{-1} = 0\cdot 5^{-1}[/tex] Compatibility with multiplication

4) [tex](x-1)\cdot (5\cdot 5^{-1}) = 0[/tex] Commutative and associative properties/[tex]a\cdot 0 = 0[/tex]

5) [tex]x-1 = 0[/tex] Existence of multiplicative inverse/Modulative property

6) [tex]x+[1+(-1)] = 1+0[/tex] Compatibility with addition/Commutative and associative properties

7) [tex]x = 1[/tex] Existence of additive inverse/Modulative property/Result

Hence, the domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].

He will have gone 3 miles after 120 minutes

Step-by-step explanation: 120/20=6        1/2 times 6 is 3.

Answer:

3 miles

Step-by-step explanation:

Divide 20 by 1/2, which would be 40. Then divide 40 by 120, and that would lead to your answer, which is 3 miles.

Answer:

When x = 2, y = 6

Step-by-step explanation:

Constant of Proportionality:  y = kx      

   (24) = k(8)

       k = 3

     y = kx       ===>        y = 3x

When x = 2:

  y = 3x

  y = 3(2)

  y = 6

Answer:

x= -7

Step-by-step explanation:

hope this helps you!

The value of x in the expressed scientific notation is;

x = -7

We are given the number 0.000000675.

Now, when writing decimals like this, it means a number has been divided by an exponent of 10.

For example; 0.01 is 1/100.

This means we start counting from the the decimal point of the whole number we want to use to the left. The number of counts we make till the end will be the exponent of 10.

Now, in our question, counting to the left from between 6 and 7 gives us 7.

Thus; we have;

6.75/10⁷

But in our question, multiplication is used and not division.

Thus, we have;

6.75 × 1/10⁷

⇒ 6.75 × 10⁻⁷

Comparing with the question gives;

x = -7

Answer:

Triangle ADB is congruent to triangle DBC

Step-by-step explanation:

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.

Answer:

a = (n + p)/m
