Answer:
-2,-1,0,1
Step-by-step explanation:
-5 ≤x≤1 and 1 ≤x+3<8
For the first statement
-5 ≤x≤1
The integers are -5,-4,-3,-2,-1,0,1
For the second
1 ≤x+3<8
Subtract 3 from all sides
1-3 ≤x+3-3<8-3
-2 ≤x<5
The integers are
-2,-1,0,1,2,3,4 ( does not include 5 since there is no equal)
There is an and between the statements so it has to be in both
-5,-4,-3,-2,-1,0,1
-2,-1,0,1,2,3,4
The numbers in both are
-2,-1,0,1
Answer:
1. 5 hours
2. 4 hours
Reason:
Formula for speed is speed = 
, if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.
Answer:
15
Step-by-step explanation:
Hello Mate!
Factor theorum states that p( x ) = 0
x = 1, 2
p( x ) = x^3 -10x^2+ax+ b
0 = 1 - 10 + a + b
0 = - 9 + a + b ------(1)
0 = 2^3 - 10(2)^2 + a(2) + b
0 = 8 - 40 + 2a + b
0 = - 32 + 2a + b ------(2)
(1) - (2)
-9 + a + b
-( - 32 + 2a - b )
23 - a = 0
a = 23
keeping value of a in eq. 1
0 = - 9 + 23 + b
-14 = b
Hope it helps☺!✌
Answer:
66° by adding up 75° and 39°, we get 114°.
since all triangles equal 180°, 180° minus 114° is 66°
