Convert the following into slope-intercept form. 3x+4y=-16
Eva8 [605]

Answer:

y = -3/4x -4

Step-by-step explanation:

3x+4y=-16

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

Subtract 3x from each side

3x -3x+4y=-3x-16

4y = -3x-16

Divide each side by 4

4y/4 = -3x/4 - 16/4

y = -3/4x -4

inysia [295]

Answer:

x = -2

Step-by-step explanation:

What is 5 1/2 of 60%
EleoNora [17]
You mean 60%of 5 1/2? that makes more sense...


i would do it like this:

\frac{60}{100}* 5\frac{1}{2}

(60% is the same as \frac{60}{100}

5\frac{1}{2}=\frac{11}{2}

(so that there is no confusion, i've put it into an improper fraction

now we can multiply:
\frac{60}{100}* \frac{11}{2}=

\frac{6}{10}* \frac{11}{2}=

\frac{3}{5}* \frac{1}{2}=



\frac{3*11}{10}=

\frac{33}{10}=

which is 3.3.

so 60% of 5 and a half is 3.3.
