Answer: the right answer is the last one
Step-by-step explanation: x= minutes and minutes there is 8 so the answer in the last one sixth.
Answer:
1:2
Step-by-step explanation:
Answer:
c = 34
Step-by-step explanation:
x²+19x+c=0
(x + a) (x + b) = x² + (a + b) x + ab
a + b = 19
a - b = 15
a = 17
b = 2
c = ab = 34
Answer:
The answer is that x = -20.
Step-by-step explanation:
The equation:
5/2x + 1/2x = 10 + 7/2x
6/2x = 10 + 7/2x
-7/2x + 6/2x = 10
-1/2x = 10
-1/2x * -2 = 10 * -2
x = -20
Proof:
5/2*-20 + 1/2*-20 = 10 + 7/2(-20)
-50 + (-10) = 10 + (-70)
-50 - 10 = 10 - 70
-60 = -60
Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (- 6, - 3)
m =
=
= 2
