Answer:
The answer to your question is the first option
Step-by-step explanation:
Process
1.- Identify the y-intercepts of the lines
blue line y-intercept = -1
brown line y-intercept = -2
With this information, we can discard the last option because those lines don't have those y-intercepts.
2.- We observe in the graphs that the lines are increasing so the slopes are positive. From this information, we can discard the second option.
3.- Calculate the slopes of the lines of options 1 and 3
Blue line Points (0, -1) (1, 2)
m =
Brown line Points (0, -2) (1, 1)
m =
As the slopes are 3, we conclude that the answer is the first option.
You need to add 2 L of the 75% mixture to get a mixture that is 60% antifreeze.
<h3>What is an antifreeze?</h3>
Anti freeze is a substance that is added in order to prevent a liquid from freezing. An antifreeze is usually an ionic substances that is used during the winter to prevent the freezing of a liquid.
Now;
Forming the equation;
0.75*x+0.5*3=0.6(3+x)
Hence;
0.75*x+1.5=1.8+0.6x
Therefore;
0.75x-0.6x=1.8-1.5
We obtain;
0.15x=0.3
Then;
x=2L

Answer:
Step-by-step explanation:
2n^2 + 6n + 2n + 6
2n^2 + 8n + 6
The answers is d. The right way to notate the yellow region indicated is D.
It looks like you tried to write
e^4^x
which I would interpret as either
(so the exponent on <em>e</em> is 4<em>ˣ </em>)
or
(so the exponent on <em>e</em> is 4<em>x </em>)
as it's shown in the question body.
If you meant the first case,
If you meant the second case,
