You question by using your brain I don’t know answers but please give me brainliest I’m trying to rank up. Y = mix+b
Answer:26 first class stamps and 28 additional.
Step-by-step explanation:
From information given,we can formulate the following equation: 47n +25(54-n ) = 1922
Now we solve for n .
47 + 1350+ 25n =1922
47n -25n =1922- 1350
22n=572
n= 26 .
Therefore 26 first class stamps and 28 additional. 54 total
slope intercept form:
y = mx + b
m = slope
b = y-intercept
the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.
y = mx + 4
the slope is technically the rate of change (rise over run) bewteen points.
If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1
y = 1x +4
this could also be:
y = x + 4
(because the 1 is invisible but still there)
Answer:
.5 < x < 16.5
Step-by-step explanation:
The smallest x can be is greater than the difference of the other two sides
8.5 -8 = .5
The largest x can be the less than the sum of the two sides
8.5+8 = 16.5
.5 < x < 16.5
Answer:
it would be b or 8 in
