Answer:
m= - 2, b = 4
Step-by-step explanation:
structure of a linear equation
y = mx + c
m = gradient / slope
c = intercept
<em>convert</em><em> </em><em>the </em><em>given </em><em>equation</em><em> </em><em>according </em><em>to</em><em> </em><em>this</em><em> </em><em>structure</em><em> </em><em>of</em><em> </em><em>linear </em><em>equations</em><em> </em>
4x+2y = 8
2y = -4x + 8
y = -2x +4
<em>according</em><em> </em><em>to</em><em> </em><em>this </em><em>intercept</em><em> </em><em>is </em><em>4</em><em> </em><em>and </em><em>slope </em><em>is </em><em>-</em><em>2</em>
The answer would be 1/4 and in decimal form 0.25
1/2 * 3/6 (Reduce 4/8 to 1/2)
1 * 3 over 2 * 6 (Use the butterfly multiplication method)
3 over 2 * 6 (Reduce 1 * 3 to 3)
3/12 (Reduce 2 * 6 to 12)
1/4 (Now lastly reduce once more and u get this)
0.25 decimal form if needed.
Answer:
Step-by-step explanation:
Find the number of possible 5-card hands that contain the cards specified. The cards are taken from a standard 52-card deck.
5 red cards.
Ans: 26C5 = 26!/[21!*5!] = 65780
--------------------------------------------
4 spades and 1 card that is not a spade.
Ans: [13C4*39C1] = 27885
--------------------------------------------
3 face cards (kings, queens, or jacks) and 2 cards that are not face cards.
Ans: 12C3*40C2 = 171,600

Answer:
x = -11
Step-by-step explanation:
Hello There!
create an equation
x + 51 + 60 + 80 = 180
combine like terms
51 + 60 + 80 = 191
x + 191 = 180
subtract 191 from each side
180 - 191 = -11
we're left with
x = -11
