Here is a system of linear equations: y= x+4 y= -3x-8

ipn [44]

Answer:

A) (-3,1)

Step-by-step explanation:

<u>Given system of linear equations: </u>

y= x+4
y= -3x-8

---

x + 4 = -3x - 8
x + 3x = - 8 - 4
4x = -12
x = -3

Then

y =-3 + 4 = 1

Solution is (-3, 1)

Correct option is A

what is a number of 3 digits and multiple of 5 but less than 600 and can be formed from 1,3,5,7 and 9?

Murljashka [212]

Any multipule of 5 ends with either a 0 or a 5

so we see that ther are no 0's in the list so it must end with 5

so the other 2 digits can be any number
wait, less than 600
so the first digit can be 1 or 3

some possible numbers are

135
175
195
315
375
395

those are the possible numbers

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 4 and 3−

Neko [114]

Answer:

$P(x) = x^3 - 10x^2+ 34x-40$

Step-by-step explanation:

Given

$p =1$ -- Leading coefficient

$Zeros: 4\ and\ 3 - i$

Required

Determine the polynomial

Represent the zeros with a and b

Such that

$a = 4$

$b = 3 - i$

The polynomial is:

$P(x) = p * (x - a) * (x - b)$

$P(x) = 1 * (x - 4) * (x - (3 - i))$

However, to solve further: We need to symmetrise over 3-i and its conjugate

$P(x) = 1 * (x - 4) * (x - (3 - i))* (x - (3 + i))$

$P(x) = (x - 4) * (x - (3 - i))* (x - (3 + i))\\\\$

To define a suitable function, the expression becomes

$P(x) = (x - 4) * ((x - 3)^2+1)$

$P(x) = (x - 4) * ((x - 3)(x - 3)+1)$

$P(x) = (x - 4) * (x^2 - 6x + 9+1)$

$P(x) = (x - 4) * (x^2 - 6x +10)$

Open bracket

$P(x) = x^3 - 6x^2 +10x - 4x^2 + 24x-40$

$P(x) = x^3 - 6x^2 - 4x^2+10x + 24x-40$

$P(x) = x^3 - 10x^2+ 34x-40$

Jada has 126 blue marbles and 135 yellow marbles. She packages them in bags of 8 marbles each. She divides the total number of m

FrozenT [24]

Answer:

Jada has 5 marbles left after filling 32 bags.

Step-by-step explanation:

Jada has 126 blue marbles and 135 yellow marbles

Total Marbles=126+135=261

She divides by 8: 261/8= $32\frac{5}{8}$ i.e. 32 Remainder 5 marbles.

The correct interpretation is Jada has 5 marbles left after filling 32 bags.
