Answer:

4 apples are $2.40

That means that 2 apples will be $1.20

And that one apple will be $0.60

$0.60*9= $5.40

She buys 5 more apples each week so she will buy 14 apples this week

$0.60*14= $8.40

Final answer : She will buy 14 apples next week for $8.40

Hope it helped! : )

Your friend is 1.2 times taller than you. Your friend is 64.5 inches tall. How tall are you?
krok68 [10]
You have to divide your friends weigh by 1.2 to get  the result. : if you were 1.2 times taller than they, you would multiply, so the oppisite is dividing!

so  it will be 64.5/1.2=53.75.

What's an equivalent equation for -5(3-2x)
kobusy [5.1K]

Answer:

-15 + 10x

or

10x - 15

(either one works)

Step-by-step explanation:

You mean you just want me to expand it?

Ok.

Multiply -5 by 3 and -2x.

(-5)(3) = -15

(-5)(-2x) = +10x

Add those together:

-15 + 10x

or

10x - 15

A parabola can be represented by the equation x2 = -20y.
aliya0001 [1]

Answer:

\mathrm{Parabola\:focus\:given}\:x^2=-20y:\quad \left(0,\:-5\right)

Step-by-step explanation:

Given the equation

x2 = -20y

A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.

4p\left(y-k\right)=\left(x-h\right)^2 is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.

so

x^2=-20y

\mathrm{Switch\:sides}

-20y=x^2

\mathrm{Factor\:}4

4\cdot \frac{-20}{4}y=x^2

4\left(-5\right)y=x^2

\mathrm{Rewrite\:as}

4\left(-5\right)\left(y-0\right)=\left(x-0\right)^2

\left(h,\:k\right)=\left(0,\:0\right),\:p=-5

Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.

\left(0,\:0+p\right)

=\left(0,\:0+\left(-5\right)\right)

\mathrm{Refine}

\left(0,\:-5\right)

Therefore,

\mathrm{Parabola\:focus\:given}\:x^2=-20y:\quad \left(0,\:-5\right)

Please check the attached figure too.
