Answer:16x-4. You add all the numbers with common terms first, such as all the xs together. Then you add all the numbers without an x in front and tada!
Step-by-step explanation:Above
Answer:
y = -2x -5
Step-by-step explanation:
The line crosses the y-axis at -5. So, b = -5.
It goes down 2 units for each 1 unit to the right, so has a slope of ...
m = rise/run = -2/1 = -2
__
The slope-intercept form of the equation of a line is ...
y = mx +b where m is the slope and b is the y-intercept
For the slope and y-intercept shown, the equation is ...
y = -2x -5
Answer: 55

Answer:
Here:
Step-by-step explanation:
x is how much she spends, y is how much she saves.
for c, you can write:
y = 300, x = 0
y = 200, x = 100
y = 100, x = 200
y = 50, x = 250
y = 1, x = 299
x and y are variables because they can vary depending on one or the other.
The formula is just a relation between x and y. For example, another way can be that I give you $10 and you buy me 5 bottles of water. But if I give you $20, you will buy 10. The amount I give you and the number of bottles you buy me are both dependent and they have a relationship no matter what value they are. And the relationship is described by the function in the question.
