Answer:

y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)

Step-by-step explanation:

There are 4 x-intercepts: -3, -2, 1, 3

So y(x) = C(x+3)(x+2)(x-1)(x-3)

At x = 0, y-intercept is -1

so -1 = C*3*2*(-1)*(-3) = 18C,

C = -1/18

Then y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)

Slope -8 and y intercept 7

max2010maxim [7]

Answer:

The equation of Line is y = - 8x + 7

Step-by-step explanation:

Given as :

The slop of line is - 8

And The y intercept is 7

As the equation of line is y = mx + c

For y intercept , x = 0

So, With y intercept and slop ,

7 = (-8)× (0)+ c

Or, c = 7

So the equation of line is

y = mx + c

I.e y = ( - 8 ) x + 7

Hence The equation of Line is y = - 8x + 7 Answer

The amount of the first alloy is 450 grams and the amount of the second alloy is 30 grams.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

A chemist has two alloys, one of which is 5% gold and 20% lead and the other which is 30% gold and 50% lead.

Let's suppose the x is the amount of the first alloy and y is the amount of the second alloy:

We can make two linear equation in two variables:

0.05x + 0.3y = 31.5 ...(1)

0.2x + 0.5y = 105 ...(2)

After solving the above two linear equations by substitution method, we get:

x = 450 grams

y = 30 grams

Thus, the amount of the first alloy is 450 grams and the amount of the second alloy is 30 grams.
