-3x^2-168 solve the quadratic equation

Answers

Answer 1

Answer:

[tex]x=+2i\sqrt{14}\ \ \,x=-2i\sqrt{14}[/tex]

Step-by-step explanation:

[tex]-3x^2-168[/tex]

The first step in solving this equation is the factor, remove a factor that both the quadratic and constant term have in common. In this case, such a term would be (-3),

[tex]-3(x^2+56)[/tex]

Now set the equation equal to zero so that one can use the zero product property. The zero product property states that any number times zero equals zero.

[tex]-3(x^2+56)=0[/tex]

Solve, use inverse operations,

[tex]x^2+56=0[/tex]

[tex]x^2=-56[/tex]

One cannot take the square root of a negative number and get a real result, thus the result is an imaginary number.

[tex]x=\sqrt{-56}[/tex]

Simplify, remove whole factors from under the radical,

[tex]x=+-2i\sqrt{14}[/tex]

solve and graph: 7x-6>22
(pls explain your answer, im confused on this)​

Answers

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

This table goes through the pairs(51,-65) and (68,-78).What is the yintercept of the line?​

Answers

Answer:

I think the y intercept is (0,-26)

Step-by-step explanation:

Answer:

(0, -26)

Step-by-step explanation:

Find the slope:

m = (-78 + 65)/(68 - 51) = -13 / 17

Use point-slope form to find the equation of the line:

y - (-65) = -13/17(x - 51)y = -13/17x + 39 - 65y = -13/17x - 26

The y-intercept is - 26

Answer: 74/9 or 8.2

Step-by-step explanation:

first add 4/9 and 1/3 since it's in parenthesis

4/9+1/3

they need to have the same denominator, use the LCM (which is 9)

multiply 1/3 by 3 to achieve the LCM

4/9+3/9

add together numerators

7/9

subtract 7/9 from 9

9/1-7/9

get 9 to achieve the LCM (which is 9 again)

multiply 9/1 by 9

81/9 minus 7/9= 74/9
