How do you solve this: 2y^2=x+4

1 answer:

5 0

To solve this for an equation that you can graph, you need to isolate the y variable. In order to do this, follow the order of operations for solving equation to get the equation.

2y^2 = x + 4 ----> divide both sides by 2

y^2 = $\frac{x + 4}{2}$ ----> take the square root of both sides

y = $\sqrt{\frac{x+ 4}{2}}$

Now you have the equation solved for the y variable and can graph it.

pav-90 [236]

Answer:

Step-by-step explanation:

The first week, she worked

$3 \times 2\frac{1}{2} = 3 \times \frac{5}{2} = \frac{15}{2}$

The second week, she worked

$3 \times 2 \frac{1}{4} = 3 \times \frac{9}{4} = \frac{27}{4}$

Total number of hours she worked over these 6 days

$\frac{15}{2} + \frac{27}{4} = \frac{57}{4} = 14\frac{1}{4}$

I don't understand number 8

Norma-Jean [14]

Let's try plugging in some negative numbers. Let's do x=-1. 5+-1=4. So we know that if we put in a negative number for x, then n will be positive. But what if we do a number greater than -5, because 5+-5=0. So let's try x=-6. So 5+(-6)=-1. Hmm. So here it is. We know that any number under -5 will be positive and any number above -5 will be negative.

Stacie is choosing between two careers. Working for company A, Stacie will make $45,000 the first year and will receive an addit

fomenos

The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is

$S=\frac{n}{2}(2a +(n-1)d)$

Where a is the first term, n is the nth term, d is the common difference

On substituting there values,we will get

$S =\frac{30}{2}(2*42000+(30-1)1800)$

= 15(84000+52200) = 15*136200 =2043000

And for company A, it is

$S= \frac{30}{2}(2*45000+(30-1)1500 ) = 15(90000+43500)=2002500$

Difference between them =2043000-2002500= 40500

So the correct option is the second option .
