well, x-intercept means for a graphed funciton where the x-axis gets touched/intercepted, Check the picture below, when that occurs, y = 0, so if we want to know what "x" is at that point we can simply set y = 0 and solve for "x".

$-3x-5y=12\implies \stackrel{\textit{setting y = 0}}{-3x-5(0) =12}\implies -3x-0=12 \\\\\\ -3x=12\implies x=\cfrac{12}{-3}\implies x = -4 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{coordinates}}{(-4~~,~~0)}~\hfill$

Answer:

74.72

Step-by-step explanation:

Given

mean $\left ( \mu \right )=70$

Standard deviation $\left ( \sigma \right )=7$

For Top 25%

$P\left ( Z$

and Z value for 75 % is 0.6744

Thus score which separates the Top 25% of students is

$=\mu +\sigma \cdot Z$

$=70+7\cdot 0.6744=74.7208$

Please help me im almost done!

Answer:

if you divide both sides of -5x > 0 you get z > 0. This is incorrect because if you choose a value from the possible solutions such as z=6 and substitute it into the original equation you get -30 > 0, which is not true
