a = 9y + 3yx

Reorder the terms:
a = 3xy + 9y

Solving
a = 3xy + 9y

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Simplifying
a = 3xy + 9y

the volume V of a gas at a constant temperature varies inversely with the pressure P. when the volume is 100 cubic inches the pr

fiasKO [112]

Answer:

The pressure is $20\ psi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem we have

$V*P=k$

where

V is the volume of a gas at a constant temperature

P is the pressure

we have

For $V=100\ in^{3}$ , $P=25\ psi$

step 1

Find the value of k

substitute the values of V and P

$100*25=k$

$k=2,500$

The equation is equal to $V*P=2,500$

step 2

Find the pressure when the volume is 125 cubic inches

For $V=125\ in^{3}$

substitute in the equation and solve for P

$125*P=2,500$

$P=2,500/125=20\ psi$

Dana is buying Grandparents' Day gifts at the mall. She spends $13.75 on a teacup for her grandmother. She spends 4/5 of that on

marysya [2.9K]

The total money Dana spent in all is $24.75

<h3>Ratio and proportions</h3>

Ratio are written as fractions of two integers. For instance a/b.

Amount spent for grandmother = $13.75

Amount spent on grand father = 4/5 * 13.75

Amount spent on grand father = $11

Take the sum

Total money spent = $13.75 + $11

Total money spent = $24.75

Hence the total money Dana spent in all is $24.75

Graph the function.

disa [49]

Answer:

Line passing through $(0,2),(1,-21)$ .

Step-by-step explanation:

$y=-23x+2\\at\ y\ axis\ x=0\\y=-23\times0+2\\y=2$

hence this line passes through $(0,2)$ .

When $x=1$

$y=-23\times1+2\\y=-21$

Hence this line passes through $(1,-21)$ .

Graph is attached.
