Answer: The correct option is D: Is alloyed with carbon and chromium to make stainless steel.

Explanation: Because of its physical characteristics, iron is a material that tends to oxidize easily. With the chromium alloy stainless steel is created, which for its quality can be used in the manufacture of structural steels.

This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate

Digiron [165]

This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate

y=8x+9<= y=8x+9 <== 8x+9: m=8

y=x^2+4x+13<= y <==x^2+4x+13: minimum (-2,9)

y=8x+9 and y.No solution

What is the value of discontinuity of x^2+8x+4/x^2-x-6? Choices:

Morgarella [4.7K]

Answer:

-2

Step-by-step explanation:

Hello,

First of all, let's check the denominator.

$x^2-x-6 \ \ \text{ *** How to factorise it ...? ***}\\\\\text{*** The product of the roots is -6=-2*3 and their sum is 1 ***}\\\\x^2-x-6=x^2-3x+2x-6=x(x-3)+2(x-3)=(x+2)(x-3)$

Now, let's see the numerator.

$x^2+8x+4 \ \text{ *** -2 is not a zero as ***}\\\\(-2)^2+8*(-2)+4=4-16+8=-4\\\\\text{*** 3 is not a zero as ***}\\\\3^2+8*3+4=9+24+4=37\\$

So we cannot factorise the numerator with (x+2) or (x-3)

Then, -2 and 3 are the the discontinuities of the expression.

There is only -2 in the list, this is the correct answer.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
