First, x intercepts are (-1,0) and (-3,0). y intercept is(0,2)
second, left side is a function because there are no x-values paired with two different y-values. right side is not a function because the x-value 3 is paired with two different y-values values
third, slope is ride over run, or the difference in y values divided by difference in x values. slope is 1/2. intercept is at (0,2). the equation is then y=1/2*x + 2
Answer:
44378.496=44,379
Step-by-step explanation:
We can write the equation using a growth equation where:
- P is the starting value
- r is the percent or rate as a decimal
- t is years
We will substitute into the formula P=25,682, r=0.2 and t =3 for 3 years since 2018 is 3 years after 2015.
Answer:
3,125
Step-by-step explanation:
25 out of 200 is 12.5%
and 12.5% of 25,000 is 3,125
(I'm not sure)
Answer:
3√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length.
x = 3√2
_____
All these triangles are similar, so the ratio of hypotenuse to leg is the same for all.
hypotenuse/leg = x/3 = (3+3)/x
x² = 3·6 = 3²·2 . . . . cross multiply (identify square factors)
x = 3√2 . . . . . take the square root
