Answer:
7*x + y + 0.1*z
Step-by-step explanation:
An expression that satisfy what Ava said she wrote is the following:
7*x + y + 0.1*z
because
- it has 3 terms (each summand);
- the coefficient (the number that multiplies the variable) of the first term is 7, of the second term is 1 (it is omitted because 1*y = y) and of the third term is 0.1;
- each term involves a different variable: x, y and z.
I can tell you about the 'ac' method of factoring trinomials by way of an example:-
Factor 3x^2 - 4x - 15
first multiply the first number by the last That is 3 * -15 = -45
Now we need to find 2 factors of -45 which will when added give - 4 ( the coefficient of x)
-9 and = 5 look like the ones so we write
3x^2 - 9x + 5x - 15
Now factor this by grouping:-
= 3x(x - 3) + 5(x - 3)
x - 3 is common to the 2 parts so we have:-
(3x + 5)(x - 3) <-------- These are your factors
Any trinomial can be factored in this way.
Answer:
Step-by-step explanation:
(x + 6)/2 = -3
x + 6 = -6
x = -12
(y - 2)/2 = 0
y - 2 = 0
y = 2
(-12, 2)
Range. Range is the difference between the largest and smallest number in a set of numbers.
