Answer:
- commutative property
- distributive property
Step-by-step explanation:
The expression
4.7x + 10.4 + 15.3x − 8.4x + 15.6
can be simplified in a few stages. First of all, we use the commutative property of addition to swap terms 2 and 3.
4.7x +15.3x +10.4 -8.4x +15.6
Next, we use the distributive property to factor x from the first two terms.
(4.7 +15.3)x +10.4 -8.4x +15.6
Now we perform addition.
20x +10.4 -8.4x +15.6 . . . . . . . . equivalent expression

Answer:
a. m = 2; y intercept = (0, 4); y = 2 x + 4
Step-by-step explanation:
The slope can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (18 -4)/(7 -0) = 14/7
m = 2
The y-intercept is the first given point: (0, 4).
The equation for the line in slope-intercept form is
y = mx + b
Here, we have m=2 and b=4, so the equation is ...
y = 2x +4
