Answer:
2 and 4
Step-by-step explanation:
the number of years after 2000 cannot be negative, nut it can be 0 since you can say that it is the year 2000
so an inequality would be t is greater than or equal to 0, and you can write this as t 
0
4 is just saying what t 0 in word form: t is greater than or equal to 0
The pythagorean theorem holds for every right triangle: given the legs 
and the hypothenuse 
, the triangle is right if and only if
So, you have to check:
So the first triangle can't be a right triangle.
So the second triangle is a right triangle.
The third triangle can't be right, because it has the same legs but a different hypothenuse
Finally, we have
So the last triangle can't be a right triangle.
Answer:
A) 1.5
B) x^2-23x+42 = (x-2)(x-21)
C) x=2, x=21
Step-by-step explanation:
a) 15 -2x / 3 = 4
15-2x = 12 (Times by three on both sides)
-2x = -3
x = -3/-2 = 3/2 = 1.5
b) x^2-23x+42
x^2-23x+42 = (x-2)(x-21)
c) x^2 -23x +42 = 0
x=2, x=21
(x-2) = 0 ⇒ x = 2
(x-21) = 0 ⇒ x = 21
Answer:
(-5, -1)
Step-by-step explanation:
Moving towards the right makes a number more positive for x and moving down makes numbers more negative for y
