This is true. An arithmetic sequence is one that either goes up or goes down by the same number every time. This equation that they gave you is linear, therefore, it will always go up or down by the same amount every time. Not so with other types of functions, but always with linear.

Write the quadratic equation in factored form. x2 + x - 12 = 0

lapo4ka [179]

Answer:

(x + 4)(x - 3)

Step-by-step explanation:

x^2 + x - 12 = 0

In order to factorise an equation, one must take into consideration the factors of the values in given equation.

In the factored form, the above equation becomes

(x + 4)(x- 3)

Factors of x^2 = x times x

Factors of -12 = +4 x -3

As shown in the factored form above

Place values for 249.673

irakobra [83]

Hi!

This question is worded a little funny, but i think in understand what it's asking. Forgive me if i'm wrong.

Place values in math are pretty self-explanatory. It's just asking you what place each number is in.

For example:

If you were to write the number 12, the 1 would be in the tens place and the 2 would be in the ones place.

When speaking about decimals, you pretty much just have to add the letters 'th' to the end of the place value, but instead of decreasing as the numbers grow smaller, you increase and the ones place doesn't exist.

So in this case:

With 249.637, 2 is in the hundreds place. 4 is in the tens place. 9 is in the ones place. 6 is in the tenths place. 7 is in the hundreths place. 3 is in the thousandths place.

Hope this helps :)

20% of Aussies have blue

notsponge [240]

Answer:

Step-by-step explanation:

Step 1: 4 = 20% × Y

Step 2: 4 = 20/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:

Step 3: Y = 4 × 100/20

Step 4:Y = 4 × 100 ÷ 20

Step 5: Y = 20
