Answer:

x^2

Step-by-step explanation:

A better word than "solve" would be "simplify." The word "equation" does not apply here, since there is no = sign and thus no equation.

The applicable rule here is

x^a / x^b = x^(a-b), so x^4/x^2 = x^(4-2) = x^2 (answer in simplest form)

Which table best represents the system of equations below. y=x-4 y=(2x-17)

vekshin1

Answer:

To make a table u need to have coordinates, (x, y).

Solve for them using substitution:

y = x - 4 ↔ x = y + 4

y = (2x - 17)

PLUG IN TO y = (2x - 17).

y = (2(y+4) - 17)

Solve for y:

y = 2y + 8 - 17

y = 2y - 9

-1y = -9

y = 9

Solve for x:

x = (9) + 4

x = 13

Keep solving for x and y to have your coordinates for your table.

Question 13 options:

Answer:

The jar has 32 dimes and 18 quarters

Step-by-step explanation:

To solve this problem we can create a system of linear equations in terms of two-variables (say $x$ and $y$ ) and solve it. To begin let us analyze the problem further. We know that the values of each coin type are:

Dimes ( $x$ ) = $0.10

Quarters( $y$ ) = $0.25

Total Value = $7.70

Total Coins = 50

Now let us set up our system of equations as:

$0.10x+0.25y=7.70$ Eqn.(1)

$x+y=50$ Eqn.(2)

Lets take Eqn.(2) and rerrange it to solve for $x$ as:

$x=50-y$ Eqn.(3)

Now lets plug this, in Eqn.(1) so we get the value of $y$ as:

$0.10(50-y)+0.25y=7.70\\\\5-0.10y+0.25y=7.70\\\\-0.10y+0.25y=7.70-5\\\\0.15y=2.7\\\\$

$y=\frac{2.70}{0.15} \\\\y=18$

Plugging in $y=18$ back in Eqn.(3) we finally have:

$x=50-18\\x=32$

Thus we conclude that in the jar the coins are:

Dimes ( $x$ ) $=32$

Quarters( $y$ ) $=18$
