This is the function
Then factor 2 out
Divide both side by two and use the quadratic formula to get the following
X=3 And x=-2 and don't forget to Chek them
If I'm right it could be C. IF I'M RIGHT, I'm not totally sure but I hope this helps.
7.846 decomposed is:
7 + 0.8 + 0.04 + 0.006
or, to see it more clearly:
7.000 + 0.800 + 0.040 + 0.006
Rounded to the nearest tenth: 7.8
Rounded to the nearest hundredth: 7.85
I hope that's what you meant :)
I think the answer would be C
As it is basically a straight line so there wouldn't be necessary for there to be a scatter diagram for it.
I may be wrong so take it with a grain of salt
Answer:
Step-by-step explanation:
I'm going to assume you mean passes through the point (-2,5) since -2 and 5 could mean a lot of different things
To find the perpendicular line's gradient, you would know that m1*m2 = -1
In this case m1 = 7, so m2 must be -1/7
Now we substitute the gradient into the equation
y = -1/7x + b
To find b, we substitute (-2,5) into the equation above
5 = -1/7*-2+b
5 = 2/7 + b
b = 33/7
Therefore the equation of the line is
y = -1/7x+33/7
