First change 5y = 10 + 2x into slope intercept form.
Slope-intercept form is y = mx + b.

5y = 2x + 10

y = 2/5x + 2

The slope in the equation is 2/5.
To find the perpendicular slope, find the negative reciprocal of 2/5.

2/5 → - 5/2

- 5/2 is the slope of the line perpendicular to 5y = 10 + 2x

I am not sure but i got y=.4x+2 because the formula for slope is y=mx+b so you solve for y and get the answer.

in recent NBA season Shaquille O'Neal made 60% of his field goals what fraction of his field goals did Shaquille make
KonstantinChe [14]
6/10 or simplified it could be 3/5 shots because 60% is the same a 60/100 so just simplify it down to the lowest common factor

Denise bought a box of 560 pieces of candy.4/5 of the pieces of the candy were fruity and 1/4 of the remaining pieces of candy w
Liula [17]

Answer:

<em>Number of Other flavor candy is 84.</em>

Step-by-step explanation:

Given that

A total of 560 pieces of candy are there in the box.

\frac{4}{5} of the pieces are fruity.

Number of Fruity pieces:

\dfrac{4}{5} \times 560\\\Rightarrow 4 \times 112 =448

Now, remaining pieces = Total pieces - Fruity pieces

remaining pieces = 560 - 448 = 112

Also given that \frac{1}4 of the remaining pieces are mind.

Number of mint pieces:

\dfrac{1}{4}\times 112 = 28

Other flavors remaining = Total pieces - Fruity pieces - Mint pieces

Other flavors remaining = 560 - 448 - 28

Other flavors remaining = 112 - 28 = <em>84</em>

<em>Number of Other flavor candy is 84.</em>
