Yes, Leonard did make an error
It should look like this:
-20x + 35 + 8 = 3x
Hope this helps!
Answer:
You are correct.
Step-by-step explanation:
The x-intercept could be written the way you have or also it can be written as a point (-1, 0).
The y-intercept could also be written as a point (0, -2) But they are commonly written the way you have also.
So, the slope is -2. But just to be clear. That slope of -2 has nothing to do with the y-intercept of -2.
If you mark all the points on the line, to get from one point to the next point, you go down 2 and over (positive direction) 1. The down 2 in math is -2 and the over 1 is just 1. The slope is that ratio of -2/1.
Slope tells us if the line is going up or down, steep or flat, even horizontal. It was coincidence only that the y-intercept and slope were the same number.
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft

Answer:
896
Step-by-step explanation:
.There are 128 pens in 1 full box. Multiply 128 with 7 (as you are trying to find the total for 7 boxes).
128 x 7 = 896
There is a total of 896 pens in 7 box's
