Hence find the value of x that satisfies the two equations y =
sammy [17]

Answer:

x=6

Step-by-step explanation:

since y=5x/2-7, and y=4x/3

         so 5x/2-7=4x/3

              5x/2-4x/3= 7

              15x-8x/6=7

               7x/6=7

               x= 7*6/7= 6

SOLUTION

TO DETERMINE

The degree of the polynomial

CONCEPT TO BE IMPLEMENTED

POLYNOMIAL

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

DEGREE OF A POLYNOMIAL

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.

EVALUATION

Here the given polynomial is

In the above polynomial variable is z

The highest power of its variable ( z ) that appears with nonzero coefficient is 5

Hence the degree of the polynomial is 5

FINAL ANSWER

The degree of the polynomial is 5

Write an equation that is parallel to the line 2x - 3y = 9 and passes through the point (4, -1).
insens350 [35]

Answer: y = \frac{2x}{3} - \frac{11}{3}

Step-by-step explanation:

Equation of the line given ;

2x - 3y = 9

To find the slope of the line we will make y the subject of formula , that is

3y = 2x - 9

y = \frac{2x}{3}-3

Therefore ; the slope = \frac{2}{3}

Two lines are said to be parallel if they have the same slope

This means that the slope of the second line = \frac{2}{3}

Using the formula y-y_{1}= m ( x - x_{1} ) to find the equation of the line , we have

y - (-1 ) = \frac{2}{3} (x - 4 )

y + 1 = \frac{2x}{3} -\frac{2}{3}(4)

y + 1 = \frac{2x}{3} - \frac{8}{3}

y = \frac{2x}{3}-  \frac{8}{3}  - 1

y = \frac{2x}{3} - \frac{11}{3}
