Find the slope and y-intercept of -x + 2y = 3. I need help on working this problem out

natita [175]

Answer:

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$

Step-by-step explanation:

A first order function has the following format:

$y = ax + b$

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.

We have the following equation:

$-x + 2y = 3$

We just have to rewrite this equation

$2y = x + 3$

$y = \frac{x+3}{2}$

$y = \frac{x}{2} + \frac{3}{2}$

Which means that

$a = \frac{1}{2}, b = \frac{3}{2}$

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$

Part A

vlabodo [156]

Answer:

Part A Option B
Part B 5.71 l and 4.29 l

Step-by-step explanation:

Let x be the volume of 5% solution

<u>Then the volume of 40% solution is </u>

10 - x

<u>Amount of acid is 10*0.20 for resultant solution, x*0.05 for 5% solution and (10- x)*0.40 is for 40% solution:</u>

10*0.20 = x*0.05 + (10 - x)*0.40

Correct equation is B.

<u>Solving</u>

2 = 0.05x + 4 - 0.4x
0.35x = 2
x = 2/0.35
x = 5.71 l of 5% solution

and

10 - x = 10 - 5.71 = 4.29 l of 40% solution
