6x+7=4x+4y complete the missing value (_,4)

Mathematics
1 answer:
hodyreva [135]3 years ago
8 0

Answer:

x = 4.5

Step-by-step explanation:

6x+7=4x+4y

The first step is to simplify the equation by combining the x terms

Subtract 4x from each side

6x-4x +7 = 4x-4x+4y

2x+7 = 4y

We know the y value is 4

Substitute y=4 into the equation

2x+7 = 4(4)

2x+7 =16

Subtract 7 from each side

2x+7-7 =16-7

2x=9

Divide by 2

2x/2 =9/2

x= 4.5

Which expressions are polynomials?
igor_vitrenko [27]

Option A: z + 1

Option B: 6 + w

Option D: 2 x^{4}-y

Solution:

Let us first define the polynomial.

A polynomial can have constants, variables, exponents and fractional coefficients.

A polynomial cannot have negative exponents, fractional exponents and never divided by a variable.

<u>To find which expressions are polynomial:</u>

Option A: z + 1

By the definition, z + 1 is a polynomial.

It is polynomial.

Option B: 6 + w

By the definition, 6 + w is a polynomial.

It is polynomial.

Option C: y^{2}-\sqrt[3]{y}+4

y^{2}-\sqrt[3]{y}+4=y^{2}-{y}^{1/3}+4

Here, y have fractional exponent.

So, it is not a polynomial.

Option D: 2 x^{4}-y

By the definition, 2 x^{4}-y is a polynomial.

It is polynomial.

Hence z + 1, 6 +w and 2 x^{4}-y are polynomials.
