Answer:

Step-by-step explanation:

no but you are very close

you forgot to put the x next to the -4

because if you left it like that than it would be a horizontal line going through the y-axis at -4

the x is very important since it is the input value while y is the output

so y depends on the x

Answer:

\displaystyle YES

Step-by-step explanation:

The equation you modeled here is \displaystyle y = -4x,where the y-intercept and x-intercept are both located at the origin. This is what is called direct variation.

I am joyous to assist you anytime.

*Just attach the <em>x</em><em> </em>to the equation because leaving it out would form a <em>horizontal</em><em> </em><em>line</em><em> </em>[<em>zero</em> <em>rate</em><em> </em><em>of</em><em> </em><em>change</em> (<em>slope</em>)].

David goes into a candy store with $5.00. He buys 9 peppermints for $0.15 each and some sour candies. Each sour candy costs $0.2
Agata [3.3K]

Answer:

5 ≥ 9*.15 + x*.25

He can buy up to 14 candies

Step-by-step explanation:

Total money ≥number of peppermints * cost per peppermint + number of sour candies * cost per sour candy

We know he has 5 dollars.  He bought 5 peppermints at $.15 cents each and x sour candies at $.25 each

Substituting in

5 ≥ 9*.15 + x*.25

5≥1.35 + .25x

Subtract 1.35 on each side

5-1.35 ≥ 1.35-1.35+.25x

3.65≥.25x

Divide by .25 on each side

3.65/.25 ≥ .25x/.25

14.6 ≥ x

He can buy up to 14 candies.  You can't buy part of a candy

Cylinder E has the following dimensions: h = 30 cm and r = 4 cm. Cylinder F has the same radius, but has a height of 5 cm . What
Anarel [89]

Answer:

1759.52cm^3

Step-by-step explanation:

Given data

Cylinder E

h = 30 cm and

r = 4 cm

The expression for the volume is

V= πr^2h

V= 3.142*4^2*30

V= 3.142*16*30

V=1508.16 cm^3

Cylinder F

h=5 cm

r = 4 cm

The expression for the volume is

V= πr^2h

V= 3.142*4^2*5

V= 3.142*16*5

V=251.36 cm^3

Hence the total volume is

=251.36+1508.16

= 1759.52cm^3
