8 because inverse operations indicate that 4x2=8
we have

we know that
this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes
1) <u>Find the y-intercept</u>
the y-intercept is when the value of x is equal to zero
For 
find the value of y


2) <u>Find the x-intercept </u>
the x-intercept is when the value of y is equal to zero
For 
find the value of x


therefore
the answer is the option B ( see the attached figure)
Point, slope, y-intercept, never, no, slope, y-intercept, same, infinite, negative coefficits, 90 degree, one, elimination, substitution, <, >, greater than or equal to sign, less than or equal to sign, greater than, less than, always, shaded area.
Hope this helps!!
Total points : 46
15% of 40 is 6
40 + 6 = 46
To double check:
46/40 = 1.15 = 115%
Answer: 640
Step-by-step explanation:
The scale factor is 20/5=4, so the ratio of the areas is the square of this, or 16.
Thus, the area of ABCD is 40(16)=640.
