Answer:

y + 5 = -2(x - 7)

Step-by-step explanation:

The slope of the line y = (1/2)x + 4 is 1/2. Any line perpendicular to this one will have a slope which is the negative reciprocal of 1/2: -2.

Using the point-slope form, the desired equation is:

y + 5 = -2(x - 7)

ikadub [295]

Answer:

Esmeralda has enough music left in her playlist for a 30 minute workout

Step-by-step explanation:

we know that

If Esmeralda accidentally deleted 25% of the music, then the percentage of music left in her playlist equals 100%-25%=75%.

$75\%=75/100=0.75$

Find out how many minutes represent 75% of 40 minutes

Multiply 40 by 0.75

$40(0.75)=30\ minutes$

therefore

Esmeralda has enough music left in her playlist for a 30 minute workout
