Part 1: Create your own quadratic equation that cannot be solved by factoring, but can be solved using the quadratic formula. Id
eimsori [14]
when you use all prime, non-one numbers for b and c, it cannot be factored most of the time


example
1x^2+7x+5
a=1
b=7
c=5
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-7+/- \sqrt{7^2-4(1)(5)} }{2(1)}
x=\frac{-7+/- \sqrt{49-20} }{2}
x=\frac{-7+/- \sqrt{29} }{2}
x=\frac{-7+ \sqrt{29} }{2} or \frac{-7- \sqrt{29} }{2}

Write an equation of the line that passes through (-5, -2) and is parallel to y = 2/3x+1
rewona [7]

Answer:

Step-by-step explanation:

Ok, so the slope has to be the same because it’s parallel.

y=2/3x+1

slope=2/3

y=-2

x=-5

y=2/3x+ what

-2=-3 1/3 + what

1 1/3

hence, y=2/3x+4/3

What is the length of the side a ?<br><br> A=
vodka [1.7K]

Answer:

a = 5

Step-by-step explanation:

Notice that \triangle CDB is a right triangle where its hypotenuse is \overline{CB}. We can also see that a = CB. For this we must use the Pythagorean Theorem.

Recall:

The Pythagorean Theorem states that if you have a right triangle, the principal square root of the sum of the squares of each leg is the length the hypotenuse.

We can see that CD = 3 and DB = 4

a = \sqrt{CD^2 +DB^2} \\ a = \sqrt{3^2 +4^2} \\ a = \sqrt{9 +16} \\ a = \sqrt{25} \\ a = 5
