P= -25/4 and that would be the answer to your question ( and now I'm sure I passed 20 characters)

I need help with 14 and 16

ArbitrLikvidat [17]

Answer:

14. (0,1)

Step-by-step explanation:

To find the solution set, substitute and evaluate each point into the given equation. If it makes it true then it is part of the solution set.

14. y = 4x + 1

(2,-1)

-1 = 4*2 + 1

-1 = 9 FALSE

(1,5)

5 = 4*-1 + 1

5 = -3 FALSE

(9,2)

2 = 4*9+1

2 = 37 FALSE

(0,1)

1 = 4*0+1

1=1 TRUE

let a,b,c,d be four integers (not necessarily distinct) in the set {1,2,3,4,5}. the no. of polynomials x^4+ax^3+bx^2+cx+d which

Eddi Din [679]

By either long or synthetic division, it's easy to show that

$\dfrac{x^4+ax^3+bx^2+cx+d}{x+1}=x^3+(a-1)x^2+(-a+b+1)x+(a-b+c-1)-\dfrac{a-b+c-d-1}{x+1}$

The quartic will be exactly divisible by $x+1$ when the numerator of the remainder term vanishes, or for those values of $a,b,c,d$ such that

$a-b+c-d-1=0$

I'm not sure how to count the number of solutions (software tells me it should be 80), but hopefully this is a helpful push in the right direction.

Which answer shows 9 x 10 ^ -5 written in standard form ?

coldgirl [10]

Answer:

D 0.00009

Step-by-step explanation:

9 × 10^-5 = 9 × 1/10^5 = 9 × 1/100,000

= 9 × 0.00001

= 0.00009

<em>Comment on place value</em>

The exponent of 10 associated with the place value in a decimal number increases from 0 to the left of the decimal point, and decreases from -1 to the right of the decimal point:

100. = 10²

10. = 10¹

1. = 10⁰

0.1 = 10⁻¹

0.01 = 10⁻²

0.001 = 10⁻³

0.0001 = 10⁻⁴

0.00001 = 10⁻⁵

This simple realization can help you immensely with scientific notation.
