grin007 [14]

Answer:

$y\geq -1 + x$

Step-by-step explanation:

$-2y\leq 2-2x\\$ Divide everything by 2

$-y\leq 1-x$ Divide everything by -1 and since y is negative, you flip the sign

$y\geq -1 + x$

X2–6x + 10 is to be written in the form ( x +a)2+ b Find the values of a and b.

vampirchik [111]

Answer:

a = -3 and b = 1

Step-by-step explanation:

x² - 6x + 10

→ Half the second term and place it in the bracket

( x - 3 )²

→ Square -3

- ( 3 )² = -9

→ Place this outside the brackets along with plus 10

( x - 3 ) ² - 9 + 10

→ Simplify

( x - 3 ) ² + 1

Simplify 3m4-2+8 <br>A.8m4 <br>B.9m4 <br>C.3m+244 <br>D.3m+284

stiv31 [10]

Answer:

$3m^4 - 2 + 8 = 3(m^4 + 2)$

Step-by-step explanation:

Given

$3m^4 - 2 + 8$

Required

Simplify

$3m^4 - 2 + 8$

Subtract 2 from 8

$3m^4 - 2 + 8 = 3m^4 + 6$

Factorize

$3m^4 - 2 + 8 = 3(m^4 + 2)$

The expression cannot be further simplified;

Hence;

$3m^4 - 2 + 8 = 3(m^4 + 2)$

Write the sum as a product of two factors 25g+10+5<br><br>

agasfer [191]

Answer:

$5\times(5g+2f+1)$

Step-by-step explanation:

$25g+10f+5$

Writing each term in its factors:

$(5\times5)g+(5\times2)f+5$

We find out that 5 is the GCF of all the terms

Factoring out 5 from the given expression.

$5\times(5g+2f+1)$

Factors: 5 and $(5g+2f+1)$

Thus:

$25g+10f+5 = 5\times(5g+2f+1)$
