Answer:
The factors are 9, y, 2, 2, y and 2.
Step-by-step explanation:
when you combine a number with another number, then that means you need to multiply. The 2 numbers that are multiplied are the factors.
5+4×(8-6) to the 2nd 9×2 to the 2nd equals 9×4 which then equals 36.
Exact form:-25/2
decimal form: -12.5
mixed number form:-12 1/2
The temperature increased by 14.
You can use a number line to think about this problem.
Answer:
y=x2 + 5
Step-by-step explanation:
A quadratic function is where the graph is in the shape of a "U" or parabola.
An example of a quadratic function if the form: y= ax^2+bx+c
What all formulas have in common is that at the end of the equation there will be a variable with no x paired with it( aka the y-intercept; the 'c' equivalent in the example formula i gave ), this letter is what tells the graph to move up or down the y-axis.
So in the answers given, ask yourself, " is there any y-intercept? And if so, is it plus 5?"
** plus 5 is the graph moving up 5 units on the y-axis
And you'd find the first answer is the only equation with a y-inter.
** side note: In y = (x + 5)^2, the 5 isn't a y-inter. bc it's inside the parenthesis. Numbers in the para. (like 5) tells the graph to move left or right ( if it is a "-" it's right and "+" is left)
