Answer:
y= 3x-2
Step-by-step explanation:
standard form
y= mx + c
c represents y intercept
m represents slope or gradient
y= 3x-2
The slope is 3 and the y intercept in -2
Answer:
military defense
Step-by-step explanation:
Promoting Military defense of itself and its allies is the foreign policy goal of United States to participate in the North Atlantic Treaty organisation.
Answer:
x = 
, y = 
<u>Explanation</u>:
2x - y= 2
3y= 4x - 5
<u>Make y the subject:</u>
2x - y= 2
-y = 2 - 2x
y = 2x - 2 <em>.........equation 1 </em>
3y= 4x - 5
y = (4x - 5)/3<em> ........equation 2</em>
From equation 1 and 2 solve them simultaneously:
→ (4x - 5)/3 = 2x - 2
→ 4x - 5= 3(2x - 2)
→ 4x - 5 = 6x - 6
→ 6x - 4x = -5 + 6
→ 2x = 1
→ x = 1/2
- if x is 1/2, then y: 2x - 2
→ 2(1/2)-2
→ -1
Solutions are 2 and 6.
Step-by-step explanation:
- Step 1: Solve for y to find the solutions.
⇒ y²/y² - 6y = 4(3 - 2y)/y(6 - y)
⇒ y²/y² - 6y = 12 - 8y/6y - y²
⇒ y²/y² - 6y = -12 + 8y/y² - 6y (Taking the negative side out from 6y - y²)
⇒ y² = -12 + 8y (Both denominators are cancelled out)
⇒ y² - 8y + 12 = 0
⇒ y² - 6y - 2y + 12 = 0
⇒ y(y - 6) - 2(y - 6) = 0
⇒ (y-6)(y - 2) = 0
⇒ y = 2, 6
Answer:
x=45/2
Step-by-step explanation:
2x-6=39
2x=39+6
2x=45
x=45/2
