Math Question plz help

Answer: y = 4/5 - 6.2

y = mx + b

first get the 2 points and plug it in to the equation

y - y1 = m (x -x1)

y - 3 = 4/5 (x - 4)

y - 3 = 4/5x - 3.2

add 3 on both sides

y = 4/5 - 6.2

Are these two expressions equal? (q-r)^2 and q^2-r^2?????

Nataly_w [17]

Answer:

$\boxed{\sf No}$

Step-by-step explanation:

$(q-r)^2$

Expand brackets.

$(q-r)(q-r)$

$q^2 -rq -rq+r^2$

Combine like terms.

$q^2 -2rq+r^2$

The expression is not equal to $q^2 -r^2$ .

SOLVE USING THE QUADRATIC FORMULA <br><br> 1) y=3x^2-x-6<br><br> 2) y=-5x^2+7x+3

kondor19780726 [428]

1) $x=\frac{1+\sqrt{73}}{6}\,\,and\,\,x=\frac{1-\sqrt{73}}{6}$

2) $x=\frac{-7+\sqrt{109}}{-10}\,\,and\,\,x=\frac{-7-\sqrt{109}}{-10}$

Step-by-step explanation:

Solving the equations using quadratic formula.

1) $y=3x^2-x-6$

The quadratic formula is:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

where a =3, b = -1 and c= -6

Putting values:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-1)\pm\sqrt{(-1)^2-4(3)(-6)}}{2(3)}\\x=\frac{1\pm\sqrt{1+72}}{6}\\x=\frac{1\pm\sqrt{73}}{6}\\so, x=\frac{1+\sqrt{73}}{6}\,\,and\,\,x=\frac{1-\sqrt{73}}{6}$

2) $y=-5x^2+7x+3$

The quadratic formula is:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

where a =-5, b = 7 and c= 3

Putting values:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(7)\pm\sqrt{(7)^2-4(-5)(3)}}{2(-5)}\\x=\frac{-7\pm\sqrt{49+60}}{-10}\\x=\frac{-7\pm\sqrt{109}}{-10}\\So, x=\frac{-7+\sqrt{109}}{-10}\,\,and\,\,x=\frac{-7-\sqrt{109}}{-10}$

Hi, there!

I'm not sure what you want to solve in these equations. Please provide me with more details. I am sorry if you were looking for answers to the question, but I simply do not know what you are asking for.

Thanks!
