Factor the following equations to find the zeros of the equation.

irina1246 [14]

The zeroes of the equation are (1,4)

Step-by-step explanation:

Given equation is:

$y = x^2 - 5x + 4$

We have to put y=0 in the equation to find zeroes of the equation

$x^2-5x+4 = 0\\x^2 - 4x- x +4 = 0\\x(x-4)-1(x-4) = 0\\(x-4)(x-1) = 0\\x - 4 =0 => x = 4\\x-1 = 0 => x = 1$

Hence,

The zeroes of the equation are (1,4)

Wilton collected $8.50 in dimes and quarters while cleaning his father's truck. If the number of quarters is 3 times the number

dusya [7]

Answer:

Wilton found 10 dimes while cleaning his father's truck.

Step-by-step explanation:

Given that:

Total amount collected = $8.50 = 8.50*100 = 850 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement,

10x+25y=850 Eqn 1

y = 3x Eqn 2

Putting y=3x in Eqn 1

$10x+25(3x)=850\\10x+75x=850\\85x=850$

Dividing both sides by 85

$\frac{85x}{85}=\frac{850}{85}\\x=10$

As x represents dimes, therefore, number of dimes is 10.

Hence,

Wilton found 10 dimes while cleaning his father's truck.
