Well 2.5 + 2.5 is 5 so 5 - 2.5 is 2.5
Answer:
5x^2 -6x +1
Step-by-step explanation:
(3х^2 – 2) + (2х^2 – бх + 3).
Combine like terms
(3х^2 + 2х^2 – бх + 3-2)
5x^2 -6x +1
Answer:
648
Step-by-step explanation:
You can use a calculator or break it into smaller problems, then add them together
What do you mean by solve?
Put in slope-intercept form would be: y<(3/4)x+1
Answer:
see below
Step-by-step explanation:
Consider the rule y = 5x + 7.
a. How many tiles are in Figure 0?
In figure 0, we let x=0
y = 5*0+7 = 0+7 = 7
b. Which figure has 37 tiles?
This means y = 37
37 = 5x+7
Subtract 7 from each side
37-7 = 5x+7-7
30 = 5x
Divide by 5
30/5 = 5x/5
6 =x
Figure 6 has 37 tiles
c. In the equation y = mx + b, what do the letters m and b represent?
m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0
