-1(7+4b) - distribute the -1 to the expression
(-1 * 7) + (-1 * 4b) — ( + and - = - )when it is multiplied
= -7 - 4b — there is no like term to added to subtracted so it will stay as like
x(x^2 - 2xy+y^2) distribute x to all
= x(x^2) - x(2xy) + x(y^2)
= x^3 - 2x^2y + xy^2 in multiplication exponent add to similar variable
No like term to connect
-5x(-3+x)
= -5x(-3) -5x(+x). (- and - is +)
= 15x -5x. similar variable x so connect the like connect like term by subtracting them
= 10x
Answer:
x=-3/11
Step-by-step explanation:
(x+3)/5 +2x=0
Multiply both sides by 5 to get rid of the fraction
5*( x+3)/5 +5*2x=0*5
x+3 + 10x =0
Combine like terms
11x +3 = 0
Subtract 3 from both sides
11x+3-3 =0-3
11x = -3
Divide by 11
11x/11 = -3/11
x = -3/11
Answer:
The graph in the attached figure
Step-by-step explanation:
we have the equation of the line in point slope form

where
the point is (5,5)
the slope is m=1/5
Remember that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
so
<em>To graph the line</em>
1. Plot the point (5,5).
2. From that point, count right 5 units and up 1 unit and plot a second point.
3. Draw a line through the two points
so
The new point is (5+5,5+1) ----> (10,6)
Plot the points (5,5) and (10,6) and draw a line through the two points
