Answer:
The lines representing these equations intercept at the point (-4,2) on the plane.
Step-by-step explanation:
When we want to find were both lines intercept, we are trying to find a pair of values (x,y) that belongs to both equations, which means that it satisfies both equations at the same time.
Therefore, we can use the second equation that gives us the value of y in terms of x, to substitute for y in the first equation. Then we end up with an equation with a unique unknown, for which we can solve:
Next we use this value we obtained for x (-4) in the same equation we use for substitution in order to find which y value corresponds to this:
Then we have the pair (x,y) that satisfies both equations (-4,2), which is therefore the point on the plane where both lines intercept.
Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8
After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9
So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)
So it's C :The median increases less than the mean increases.
(-0.2,1.2)
substitute 3x+2 for y and set them equal to eachother then plug in x for y
For the first one, find a number in which, when factored, will give you 4.
x² + 4x + 4
x 2
x 2
(x + 2)(x+ 2)
4 is your best answer
2. x² - 10x + ____
Same for this question. Find a number that, when factored, will give you -10
-100
x² - 10x + 25
x - 5
x -5
(x - 5)(x - 5)
25 is your answer
hope this helps
