Answer:
1 < x ≤ 4
Step-by-step explanation:
Given
8 ≥ x + 4 > 5 ( subtract 4 from each of the 3 intervals )
4 ≥ x > 1
Hence
1 < x ≤ 4
Answer:
x = 12
Step-by-step explanation:
the two equations shown should add up to 180. so I did this equation: (10x-20)+ (6x+8) = 180 and I solved for x
Answer:
the answer 6.3%
Step-by-step explanation:
Answer:
Rate of change or slope = 
Step-by-step explanation:
It is common that most lines that are graphed are in slope intercept form.
y=mx+b
M represents the slope.
In the question you're asking M = 1/3
The slope of the first equation has a slope of one and a y intercept of -4. The second equation has a y intercept of -2.3333 as seen when plugging in 0 for x, so the same y-intercept and same line are out of the question. This means either they have the same slope and thus are parallel or intersect at some point. A simple way to find out? Plug in 1 for x on the second. If it isn't -1.33333, which is a slope of positive 1 such as in the first equation, they WILL INTERSECT somewhere. When plugging in 1, we get
3y - 1 = -7
3y = -6
y = -2
(1, -2) is the next point after (0, -2.3333)
That means it is most certainly not the same slope, and thus they will intersect at some point. The two slopes are 1/1 and 1/3 if you weren't aware.
