What is the slope of 6x+10y=8<br> (choice A)<br> A -3/4<br><br> B -5/4<br><br> C -3/5<br><br> D -4/5
kvv77 [185]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 6x + 10y = 8 into this form by subtracting 6x from both sides

10y = - 6x + 8 ( divide all terms by 10 )

y = - \frac{3}{5} x + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C

If 23/8, 11/2, 9/6, and 15/7 are placed in order from least to greatest, which would be first?
yarga [219]

Answer:

\frac{9}{6}

Step-by-step explanation:

The given fractions are;

\frac{23}{8},\frac{11}{2},\frac{9}{6},\frac{15}{7}

The least common denominator is 168.


We express all the fractions in equivalent form with the LCD as the denominator.


\frac{23}{8}=\frac{21\times23}{21\times8}=\frac{483}{168}


\frac{11}{2}=\frac{84\times11}{84\times2}=\frac{924}{168}


\frac{9}{6}=\frac{28\times9}{28\times6}=\frac{252}{168}


\frac{15}{7}=\frac{24\times15}{24\times7}=\frac{360}{168}


We now compare the equivalent forms and arrange from the least to the greatest.

\frac{252}{168}\:

This implies that,

\frac{9}{6}\:

Therefore the first would be \frac{9}{6}.
