Answer:
An irrational number between -2 and -1 would be 
A rational number between -2 and -1 would be -1.5
Step-by-step explanation:
= -1.570796... This number does not have repeating decimals, patterns, and it isn't a terminating decimal. It is irrational.
-1.5 is a terminating decimal, therefore it is rational, as well as between -2 and -1.
Answer:
x=-1
Step-by-step explanation:
-8x+32=40
-8x=8
x=-1
Exterior angle c = the sun of the two opposite interior angles a and b.
10x -23 = 5x -17 + 7x -26
Combine the right side:
10x -23 = 12x -43
Add 43 to both sides:
10x +20 = 12x
Subtract 10x from both sides:
20 = 2x
Divide both sides by 2
X = 10
Now you have x replace it in the equation for A:
A = 5x -27 = 5(10) -27 = 50-27 = 23
Angle A = 23 degrees.
Answer:
x-intercepts: (2, 0) and (−5, 0)
y-intercept: (0, −10)
Step-by-step explanation:
y = x^2 + 3x − 10
y-intercept when x = 0 so y = -10, so y-intercept : (0, -10))
x-intercept when y = 0 so
x^2 + 3x − 10 = 0
(x +5)(x - 2) = 0
x + 5 = 0; x = -5
x - 2 = 0; x = 2
So x-intercepts: (-5, 0) and (2,0)
