This is right because the goal of solving a quadratic equation is to isolate the variable and then solve it. First you multiply - 8/3 to both sides to isolate s and the you solve the equation by multiplying - 8/3 to - 6
Answer:
the graph is in link
Step-by-step explanation:
y ..... means full line and shading above the line
Y< ......means doted line and shading below the line
A) solution is overlapping shaded part
B) (10,5)
plug in point in inequalities and check if it's true; if it's true you showed that solution is correct
1. 5-1/2*10 + 2 1/2
5 -5 + 2 1/2
5 -2 1/2 TRUE
2. 51/5*10 + 6
5< 2 + 6
5< 8 TRUE
(2.1 x 103) x (3.5 x 102)
216.3×357
77219.1
Subtract 15 from both sides.
5x=-15
Divide by 5
x=-5
