Answer:
20x - 4
Step-by-step explanation:
4 less than 20 times some number
Let's break it up.
4 less than = -4
20 times some number = 20x (x is representing "some number")
So, let's put that together.
4 less than 20 times some number
20x - 4
The quadratic function when graphed out should look like either a 'U' or an 'n' (parabola). Quadratic functions have formulas which are typically in the form of: A(x^2)+Bx+C where A, B, C are numbers and if you plot them then as mentioned before you should get a parabola.
Answer: slope is 1; y intercept is -5
=========================================================
The equation y = x-5 is the exact same as y = 1x-5. The 1 in front of the x does not change it because 1*x = x. It's the idea of 1 times any number is itself (eg: 1 times 7 = 7)
We can rewrite y = 1x - 5 into y = 1x + (-5). Adding a negative is the same as subtracting.
The equation y = 1x + (-5) is in the form y = mx+b where m = 1 and b = -5
So the slope is m = 1 and the y intercept is b = -5. The graph crosses the y axis at the point (0,-5)
Answer:
x = -5
Step-by-step explanation:
Multiply 3 by (6x - 4x) = 18x - 12x
18x - 12x = -30
6x = -30
x = -30 /6
x = -5
