Answer:
B
Step-by-step explanation:
A(-7,4) and B(0,6);
A(x₁,y₁) and B(x₂,y₂)
Equation form : y =mx+b
1st Calculate the slope m:
m=(y₂-y₁)/(x₂-x₁) = (6-4)/(0+7), m = 2/7
the equation becomes: y= 2/7.x +b
2nd Calculate b. to that end you plug any coordinates (either A or B) in the equation y=2/7.x + b:
Let's say I selected B(0,6)
6=2/7(0) +b and b =6
The final equation : y =(2/7).x + 6

<u>System Of Equations
</u>
We know the scale shows a false reading for the weights by a constant value. Let's call e the weight it adds or subtracts from the real weight it measures.
When the box is put on the scale, the real weight is b, but the scale shows
When the bag is weighted, the real value is g, but the scale shows
Finally, when both are measures, the real weight is b+g and the scale shows
We have formed a system of equations. It's easy to find the value of b, we just need to subtract the last two equations
Hey there! :)
Answer:
First option: As x⇒ ∞ f(x) ⇒ -∞. As x⇒ -∞ f(x) ⇒ ∞.
Step-by-step explanation:
Rearrange the equation:
f(x) = -x³ - 2x² + 1
This is a negative cubic function. The function decreases over the interval
(-∞, ∞). Therefore:
As x⇒ ∞ f(x) ⇒ -∞.
As x⇒ -∞ f(x) ⇒ ∞.
This is the first option.
Answer:
Step-by-step explanation:
Take the given data set and arrange it in ascending order from smallest to largest value. The smallest value (the first number i this set) is the 'minimum value,' and the largest value (the last number) is the maximum.
The minimum and the maximum of a data set are "extreme values."
