It is stated that their are closed circles on -4 and 3. This means, both -4 and 3 are also included in the interval.
The following regions are included in the range:
a) -4
b) Numbers between -4 and 3
c) 3
d) Numbers greater than 3
So, the number line represents:
x greater than or equal to -4 and x less than or greater to 3.
Therefore, the first option gives the correct combined inequality.
Answer:
i believe the answer is 0,2
#2
2x - 4y = -2
2x + 3y = -16
------------------subtract
-7y = 14
y = 14/-7
y = -2
2x - 4y = -2
2x - 4(-2) = -2
2x + 8 = -2
2x = -2 -8
2x = -10
x = -10/2
x = -5
answer x = -2 and y = -5
check:
2(-5)- 4(-2) = -2
-10 +8 = -2
-2 = -2.....true
2x + 3y = -16
2(-5)+3(-2) = -16
-10 + (-6) = -16
-16 = -16...true
40 x 10 = 400
400 / 100 = 4
Mai has 4 hundreds.
The initial velocity is 19 ft/s.
This is in the form f(t) = -16t²+v₀t+h₀, where v₀ is the initial velocity. 19 is in the place of v₀, so it is the initial velocity.
