Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
The decimal for 8/18 is 0.44, you simplify 8/18 to 4/9, divide 4 by 9 for the decimal.
249863.73/216.06
=115.6471
Answer:
66000
Step-by-step explanation:
since the graph represents a proprtional relationship the equation of the graph must be written this way :
y = ax where a is the slope
you can notice that 2 goes with 24000
so 24000 = 2a then x = 24000/2= 12000
so a = 12000
now replace x with 5.5
y= 5.5*12000=66000
Answer:
1/36
Step-by-step explanation:
When the coefficient is 1, the function has zeros at -3 and -5, one horizontal unit from the vertex. You want to move the zero to (2, 0), which is 6 units from the vertex. To achieve a horizontal stretch by a factor of 6, the value of x in the function must be replaced by x/6. That would make the coefficient of x^2 be (1/6)^2 = 1/36.
The coefficient of the squared term is 1/36.
