The equation represents two equivalent expressions [ similar sides ]
Hope this helps!
3-4=-1. To use mental math, imagine that there is a number line in your head. Start at three, and since we're subtracting, move to the left 4 units. This will land you at -1. I hope this gets easier for you in the future!
Answer:
Step-by-step explanation:
Let n represent the number
Twice the number =2n
4 times the number = 4n
Given that twice the number is atleast 3 less than four times the number
Algebraically this can be written as
2n≤4n-3
We can add 3 to both sides
So n should be atleast 1.5
If n is natural number or integer then least value of n is 2.
Step-by-step explanation:
the line passes through (0,-2) and perpendicular to the graph of y=5x+7.
solution :
the slope = -1/5
the equation :
y+2 = -1/5 (x-0)
y = -1/5x - 2
Respuesta:
(segundo + 3) (segundo + 2) = 0
Explicación paso a paso:
Dada la expresión cuadrática b² + 5b + 6, debemos factorizarla;
b² + 5b + 6 = 0
b² + 2b + 3b + 6 = 0
b (segundo + 2) +3 (segundo + 2) = 0
(segundo + 3) (segundo + 2) = 0
Por tanto, el factor requerido es (b + 3) (b + 2) = 0
