Answer 1

Answer:

72/149

Step-by-step explanation:

Just to clarify, the curly braces mean the same thing as normal parenthesis.

(12 + 5^2) = (12 + 25) = 37

(-7-15)^2 = (-22)^2 = 484

6^3  = 216

(12 + 5^2) - (-7-15)^2 = 37 - 484 = 447

6^3 / ((12 + 5^2) - (-7 - 15)^2) = 216 / 447 = 72/149

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y​

Answers

Answer:

The value of x is 2.

The value of y is [tex]\frac{7}{6}[/tex]

Step-by-step explanation:

x:

We have that:

[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]

Multiplying everything by 3

[tex]x + 3 = 5[/tex]

[tex]x = 2[/tex]

The value of x is 2.

y:

We have that:

[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]

Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.

[tex]6y - 4 = 3[/tex]

[tex]6y = 7[/tex]

[tex]y = \frac{7}{6}[/tex]

The value of y is [tex]\frac{7}{6}[/tex]

Answer:

x=1, y=-2

Step-by-step explanation:

2x-3y=8 (1)                            

4x+3y=-2 (2)

From (1):

2x=8+3y

x=4+1.5y (3)

Subst (3) into (2)

4(4+1.5y)+3y=-2

16+6y+3y=-2

16+9y=-2

9y=-2-16

9y=-18

y=-2

subst y=2 in to (3)

x=4+(1.5*-2)

x=4-3

x=1

Find the roots/zeroes of the following polynomial

x^2−19=6

Answers

Answer:

x=5 and x=-5

Step-by-step explanation:

1. first you would subtract 6 from both sides to set the equation = to zero.  

2. The equation would then be x^2-25=0.

3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0

4. by the zero product property, the roots are 5 and -5.

Simplify: 14ba2+21ab2−ab2.

Answers

14ba^2+20ab^2 because you subtract one from 21ab^2

The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².

What is simplification?

In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.

The expression is given in the question, as follows:

14ba²+21ab²−ab²

When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².

Thus, the given expression can be simplified to 14ba²+20ab².
