When the polynomial is written in standard form, what are the values of the leading coefficient and the constant? 5x + 2 - 3x^2

1 answer:

7 0

Leading coefficient = -3
Constant = 2

When you order them in standard form, you need to put them in ascending order of the exponents. Therefore the -3x^2 would come first, which makes the number attached (-3) the lead coefficient.

Also, since the number (2) without an x attached would be last (due to the power of x technically being 0), than that is the constant.

3x + y = -2<br> x = 2 - y

andrezito [222]

Answer:

$y = 4 \\ x = - 2$

Step-by-step explanation:

$3(2 - y) + y = - 2 \\ 6 - 2y = - 2 \\ 2y = 8 \\ y = 4 \\ \\ x = 2 - 4 \\ x = - 2$

Eliza is at least twice as old as her friend's younger sister, Wendy.

satela [25.4K]

Answer:

e ≥ 2w

Step-by-step explanation:

To make this easier, let us consider the case of Eliza being exactly twice as old as wendy

that would mean that twice the age of Wendy is the age of Eliza

e = 2w

but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy

Hence, the symbol '=' will be replaced by '≥'

Hence, the correct relation is

e ≥ 2w

After observing this pattern, Guido made a conjecture for the next shape in the pattern.

Valentin [98]

Answer:

Correct answer is upper right rectangle (with 3rd strip shaded)

Step-by-step explanation:

Observe the pattern carefully. This pattern consists of 5 rectangles. Each rectangle is divided into 4 vertical strips.

The 1st rectangle has one shaded strip - the 4th strip, the 2nd rectangle has shaded strip - the 3th strip, the 3rd rectangle has one shaded strip - the 2nd strip, the 4th rectangle has shaded the 1st strip

and so on

the 5th rectangle has shaded the 4th strip, the 6th rectangle has shaded the 3rd strip, ...

Thus, correct answer is upper right rectangle (with 3rd strip shaded)
