tankabanditka [31]

All you have to do is x times 42 plus y times 42 and then you have to add the first day on which is 89.This is how it should look (x*42)+(y*42)+89.

M(x)=1/x f(x)=2x-10 find the domain restriction of m(R(x))

AlexFokin [52]

Answer:

x ≠ 5

Step-by-step explanation:

Given

m(x) = 1/x
f(x) = 2x - 10

Composite function

m(f(x)) = 1/ (2x - 10)

The denominator can't be zero

2x - 10 ≠ 0
2x ≠ 10
x ≠ 5

( x − 3 ) ( x − 1 ) (x−3)(x−1)

galina1969 [7]

Answer:

x² - 4x + 3

Step-by-step explanation:

When multiplying binomials (two terms in an expression), use FOIL. It stands for the first, outside, inside, and last terms in each bracket.

(x−3)(x−1) Expand with FOIL

= x² - x - 3x + 3 Collect like terms

= x² - 4x + 3

In a genetic experiment involving flower color in phlox, a ratio of 3 blue-flowered plants to 1 whiteflowered plant was expected

aliya0001 [1]

Answer: The observed ratio is different from the expected ratio.

Step-by-step explanation:

Since we have given that

Expected ratio :

Ratio of blue flowered plants to white flowered plant = 3:1

Observed results:

Number of blue flowered plants = 35

Number of white flowered plants = 14

So, Ratio of blue flowered plants : white flowered plants

$35:14\\\\=5:2$

So, 5:2 ≠ 3:1

Hence, the observed ratio is different from the expected ratio.
