Mathematics
1 answer:
lukranit [14]3 years ago
7 0

Answer:

C) 6

Step-by-step explanation:

Given: b(X) = l x + 4 l

Now plug x = -10 in the given function, we get

b(-10) = l -10 + 4 l

b(-10) = l -6 l

The given function is an absolute function, the absolve value is always positive.

The absolute value is nothing but distance from the origin. The distance cannot be negative. Therefore, the absolute value is always positive.

Therefore, b(-10) = 6

Answer: C) 6

Hope you will understand the concept.

Thank you.

A chemist has two alloys, one of which is 5% gold and 20% lead and the other which is 30% gold and 50% lead. How many grams of e
dmitriy555 [2]

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.
