Which equation is equal to 4a+2b=10 A. b=-2a+10 B. 2a+5 C. b=-2a+5 D. b=2a+10

4a + 2b = 10

you are solving for b

isolate the b

subtract 4a from both sides

4a (-4a) + 2b = 10 (-4a)

2b = 10 - 4a

divide 2 from both sides to isolate the b

2b(/2) = (10 - 4a)/2

b = (10 - 4a)/2

b = 5 - 2a

C) b = -2a + 5 is your answer

hope this helps

Match each quadratic equation with its solution set.

Marianna [84]

Answer:

( 8 , - 8) => x² - 55 = 9

( 4 , - 4) => 2x² - 32 = 0

(5 , - 5) => 4x² - 100 = 0

(11 , - 11) => x² - 140 = -19

( 3, - 3) => 2x² - 18 = 0

Step-by-step explanation:

$2x^2 - 32 = 0\\\\2(x^2 - 16 ) = 0 \\\\x^2 - 16 = 0 \\\\x^2 = 16 \\\\x = \sqrt {16 } = \pm 4$

x = ( 4 , - 4)

$4x^2 - 100 = 0 \\\\4(x^2 - 25 ) = 0\\\\x^2 - 25 = 0 \\\\x^2 = 25 \\\\x= \sqrt{25} = \pm 5$

x = ( 5 , - 5 )

$x^2 - 55 = 9 \\\\x^2 = 9 +55\\\\x^2 = 64\\\\x = \sqrt{64} = \pm 8$

x= ( 8 , - 8)

$x^2 - 140 = - 19\\\\x^2 = -19 + 140 \\\\x^2 = 121 \\\\x= \sqrt{121} = \pm 11$

x = ( 11 , -11)

$2x^2 - 18 = 0\\\\2(x^2 - 9) = 0\\\\x^2- 9 = 0 \\\\x^2 = 9 \\\\x = \sqrt9 = \pm 3$

x = ( 3 , - 3)

How do you factor the expression<br> 20k+50

Aliun [14]

Answer is 10(2k+5)

-----------------------------------

Work Shown:

20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)

Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer

Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
