Answer:
x=-6 and y=-3
mrk me brainliest plz
Step-by-step explanation:
Step: Solve−3x+y=15 for y:
−3x+y=15
−3x+y+3x=15+3x (Add 3x to both sides)
y=3x+15
Substitute 3x+15 for y in−3x+7y=−3:
−3x+7y=−3
−3x+7(3x+15)=−3
18x+105=−3(Simplify both sides of the equation)
18x+105+−105=−3+−105 (Add -105 to both sides)
18x=−108 divide both side by 18
x=-6
Answer:
C
Step-by-step explanation:
C
Y - y1 = m(x - x1)
m = -2 (1, -5)
y - (-5) = -2(x - (-5)
y + 5 = -2(x + 5)
y + 5 = -2x - 10
y = -2x - 15 <<< answer
hope this helps, God bless!
Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units
