A quadratic equation is shown below:
lys-0071 [83]
16x^2 − 8x + 1 = 0

<span>Part A: 
</span>b^2 - 4ac for ax^2 + bx + c

16x^2 − 8x + 1 = 0
so in this case,
a = 16,  b = -8, c = 1

b^2 - 4ac
=(-8)^2 - (4 * 16* 1)
= 64 - 64
= 0
because it's equal 0, answer is one solution

Part B:

<span>4x^2 − 8x − 45 = 0
</span><span>solve the equation by factoring </span> 
= (2x - 9)(2x + 5)

set (2x - 9)(2x + 5) equal to 0 to solve for x
so
(2x - 9)(2x + 5) = 0
2x - 9 = 0
  x = 9/2
  x = 4.5

2x + 5 = 0
  x = -5/2
  x = -2.5
answer
x = -2.5 or x = 4.5

Hope it helps

????????????????????

Greetings!

Substitute:
x+y=1000 \\ x=1000-y
Now we can input this into the other equation so, we only have one variable.

Solve for y.
0.05(1000-y)+0.06y=57
Distribute the parenthesis.
50-0.05y+0.06y=57
Combine Like Terms.
50-0.01y=57
Add -50 to both sides.
(50-0.01y)+(-50)=(57)+(-50)
Simplify.
0.01y=7
Divide both sides by 0.01.
(0.01y)/0.01=(7)/0.01
Simplify.
y=700

Input this value into the other equation.
x+700=1000
Add -700 to both sides.
(x+700)+(-700)=(1000)+(-700)
Simplify.
x=300

The answer would be 300,700

Hope this helps.

PLEASE HELP IM DESPERATE I DID THIS KHAN AT LEAST 7 TIMES IM SO DEPRESSED I JUST WANT TO GET THIS DONE WITH!
crimeas [40]

Answer:

y = (-3/2) x + 3

Step-by-step explanation:

The line passes through (0, 3) and (2, 0)

Slope = (0 - 3)/(2 - 0) = -3/2

Let y = (-3/2) x + b

Use (0, 3) to get b:

3 = (-3/2)*0 + b, so b = 3

Then y = (-3/2) x + 3
