How do you solve 4x squared - 12x = 7 (ALGEBRAICALLY)
amm1812
4x^2-12x=7 \\
4x^2-12x-7=0 \\ \\
a=4 \\ b=-12 \\ c=-7 \\ b^2-4ac=(-12)^2-4 \times 4 \times (-7)=144+112=256 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-(-12) \pm \sqrt{256}}{2 \times 4}=\frac{12 \pm 16}{2 \times 4}=\frac{4(3 \pm 4)}{2 \times 4}=\frac{3 \pm 4}{2} \\
x=\frac{3-4}{2} \ \lor \ x=\frac{3+4}{2} \\
x=-\frac{1}{2} \ \lor \ x=\frac{7}{2} \\ \\
\boxed{x=-\frac{1}{2} \hbox{ or } x=\frac{7}{2}}

In a survey , rajveer asked 110 people whether they were employed or unemployed.
storchak [24]

Answer:

7

Step-by-step explanation:

Create a two-way table with the given information:

\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & & 59 \\\cline{1-4} \sf Women & & &  \\\cline{1-4} \sf Total & 84 & & 110 \\\cline{1-4} \end{array}

Fill in the blanks in the table using <u>mathematical operations</u>:

⇒ Men unemployed = 59 - 40 = 19

⇒ Women employed = 84 - 40 = 44

⇒ Total women = 110 - 59 = 51

⇒ Total unemployed = 110 - 84 = 26

⇒ Women unemployed = 51 - 44 = 7

\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & 19 & 59 \\\cline{1-4} \sf Women &44 & 7& 51  \\\cline{1-4} \sf Total & 84 &26 & 110 \\\cline{1-4} \end{array}

Reading from the table, 7 women responded that they were unemployed.
