18m
Step-by-step explanation:
5x3=15 +3 =18
For these kinds of expressions use FOIL (first, outside, inside, last).
-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2
Now combine them all:
-18x^2 + 78xy - 24y^2
Answer:
The graph in the attached figure N 2
Step-by-step explanation:
The complete question in the attached figure N 1
we have the ordered pairs
(-4,9),(-1,3),(0,1),(2,-3)
Using a graphing tool
Plot the given ordered pairs in the coordinate plane
Remember that
In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis
see the attached figure
The graph represent a line
<em>Find the equation of the line</em>
<em>Find the slope</em>
take two points

The equation of the line in slope intercept form is equal to

we have

substitute

Answer:
Look it up. it will help you work it out. hope this helped.
Step-by-step explanation:
150 x 5= 750
20 x 5= 100 ... so they should expect 100 cellphones to be defective
