Find the x-intercept(s) of y = 2x2 - 3x - 5.<br> A) -5 <br> B) 2 1/2, -1<br> C) 3, -5 <br> D) 5, -1

Alexus [3.1K]

Answer:

$\large\boxed{B)\ 2\frac{1}{2},\ -1}$

Step-by-step explanation:

x-intercepts are for y = 0.

We have the equation:

$y=2x^2-3x-5$

Therefore

$2x^2-3x-5=0\\\\2x^2+2x-5x-5=0\\\\2x(x+1)-5(x+1)=0\\\\(x+1)(2x-5)+0\iff x+1=0\ \vee\ 2x-5=0\\\\x+1=0\qquad\text{subtract 1 from both sides}\\\boxed{x=-1}\\\\2x-5=0\qquad\text{add 5 to both sides}\\2x=5\qquad\text{divide both sides by 2}\\\boxed{x=2\frac{1}{2}}$

Solve y In terms of x

miss Akunina [59]

the answer is $y=3x-6$

subtract 6x on both sides → $-2y=-6x+12$

divide both sides by -2y → $y=3x-6$

9.2 million was calculated as a percentage of 132 million. likewise 13.4 million was determined as a percentage of 142 million.

lora16 [44]

I assume you need the difference between the percentages,

if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%

142 mil...........................100%
13.4 mil..........................y

y=(13.4 *100)/142= 9.43%

the difference is
9.43-6.96=2.47 %
