MATH HELPERS PLEASE HELP!!!!

1 answer:

8 0

2x + 3 < 19
2x < 16
x < 8 (inequality 1)

2x - 3 ≤ -7
2x ≤ -4
x ≤ -2

Since both inequalities have a less than sign, the domain will go down to negative infinity. Since they have a common solution from x ≤ -2, the interval notation becomes (- infinity, -2]

Which equation is equivalent to 4s=t+ 2?S= 1-2S=4/t+2S =t+2/4 S=t+6

Marina CMI [18]

SOLUTION:

We are to make S the subject of the formula;

$\begin{gathered} 4S\text{ = t + 2} \\ \text{Divide both sides by 4} \\ \frac{4S}{4}\text{ = }\frac{t\text{ + 2}}{4} \\ S\text{ = }\frac{t\text{ + 2}}{4} \\ \\ \end{gathered}$

The correct option is the third one.
