For the second question answer -10 and -4
The second one factor two numbers that add to 14 and when you multiply the numbers you get 40. Are 10 and 4
(X+10)(X+4)
X+10=0
Subtract 10 on both sides
X=-10. Answer
X+4=0 subtract 4
X=-4
3rd question X= 2 and X= -9

Two numbers that add to -7 and multiply to -18 are -2+9=-7. -2 times 9=-18
(X-2)(X+9)=0
X-2=0 X= 2. X+9=0 X=-9

miskamm [114]

Linear equation are the equation which has the power of the unknown variable is 1. The Emily have total 2 number of dimes coin and total 6 number of nickels coin.

<h3>Given information-</h3>

Emily has 8 coins in her purse totaling 50 cents

The only kinds of coins she has are nickels and dimes.

<h3>Nickel</h3>

A nickel is a coin which has the value equal to the 5 cents.

<h3>Dimes</h3>

A dimes is a coin which has the value equal to the 10 cents.

Suppose the number of nickel coin is <em>x </em>and the number of dimes coin is <em>y.</em>

As total coins are 8 . Thus,

x+y=8      

x=8-y                  ......equation 1

As the total value of the cents is 50 and nickel is equal to the 5 cents whereas the dimes is equal to the 10 cents. Thus,

5x+10y=50        

Put the value of the <em>x</em> from the equation 1 in the above equation.

\begin{aligned}5(8-y)+10y &=50\\40-5y+10y &=50\\5y &=50-40\\y&=\dfrac{10}{5} \\y&=2\end

Thus Emily have total 2 number of dimes coin.

Put this value of y in equation 1 we get,

x=8-2\\x=6

Thus  Emily have total 6 number of nickels coin.

Hence the Emily have total 2 number of dimes coin and total 6 number of nickels coin.
