To factor this notable trinomial, you have to find two numbers that summes give -5 and multiplied give 6*(-25) = -150
Then let's call n1 and n2 the two numbers and a the number before x^2 (6)
ax^2+sx+fn = (ax + n1)(x + n2/a)
Numbers are -15 and +10
-15+10 = -5
-15*10 = -150
So
(6x-15)(x + 10/6)
Or write it as a sum
6x^2 + 10x - 15x - 25
And factor
6x^2 + 10x = 2x(3x+5)
-15x-25 = -5(3x+5)
(2x-5)(3x+5)
Answer:
x and y are the input and output of the function. The graph attached is all the values of x and y. For a specific value, more information is needed.
Step-by-step explanation:
56x+34y=4376 is a linear function with two variables. It represents the rule between inputs (x) and outputs (y). To find all its values of x and y, graph the equation.
Answer:
165
Step-by-step explanation:
since the ticket cost $5.50 per child
so $5.50*30=165
Answer:
-8
Step-by-step explanation:
3x4= 12, 7+3=10x2=20
12-20= -8
The definition of sin is the opposite/hypotnuse and since the hypotnuse has to be greater or equal to the other sides, the maximum possible value of sine is 1.
