Answer:
Please use " ^ " for exponentiation: x^2 + 2x + 8 ≤ 0.
Let's solve this by completing the square:
x^2 + 2x + 8 ≤ 0 => x^2 + 2x + 1^2 - 1^2 + 8 ≤ 0. Continuing this rewrite:
(x + 1)^2 + 7 ≤ 0
Taking the sqrt of both sides: (x + 1)^2 = i*sqrt(7)
Then the solutions are x = -1 + i√7 and x = -1 - i√7
There's something really wrong here. I've graphed your function, x^2 + 2x + 8, and can see from the graph that there are no real roots, but only complex roots. Please double-check to ensure that you've copied down this problem correctly.
Answer:
<h2>The answer is - 2</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3, −7) and (−1, 1)
The slope is
We have the final answer as
<h3>- 2</h3>
Hope this helps you
Answer:
C: Mintu should have chosen a material with a lower specific heather lower the specific heat the faster it will heat up and transfer the heat on to the new metal he wants to shape allowing it to be molded faster.
CHOICES
A:Mintu should have decreased the size of the metal iron
B:Mintu should have decreased the time he touches the two metals
C:Mintu should have chosen a material with a lower specific heat
D:Mintu should have chosen a material the same temperature as the iron.

When we are multiplying the two numbers, we should notice that they share the same base. Because of this, we can add the exponents when we multiply them.
