Solve by using Substitution method-
-2x+9y=-9
9x-2y=2
Step by step needed asap
Answer:
(0,-1) I could be wrong
Step-by-step explanation:
Answer:
Step-by-step explanation:
-2x+9y=-9 (solve for x)
-2x= -9y-9
X = - 9y/-2 - - 9/2. X = 9y/2 + 9/2
9(9/2y+9/2)-2y=2
81y/2 + 81/2 - 2y = 2
81y/2 - 2y = 2 - 81/2. 81/2 - 2 = 77/2 and -81/2 +2 = -77/2
77/2 y = - 77/2
y = (-77/2)/(77/2)
y = - 1

X/3 - X/6 = 2
What is the value of x how do I do it?
Answer:
Value of X is 18
Step-by-step explanation:
x/3 - x/6 = 2
multiply first fraction by 3 so u get X by its self then multiply the 2 by 3
x - x/6 = 6
then multiply the fraction by 6 to get X by itself then multiply the 6 by 6 because what u do to one side u have to do to the other
2x/2 = 36/2
x= 18

The perimeter of the school crossing sign is 102 inches. What is the length of each side?
Equation: _ =102
s=_
Question 2
Label the length of each side in inches
Answer:
1) s=15
2) 15, 21, 21, 15, 30 from left to right
Step-by-step explanation:
First you turn this into an equation: s+6+s+6+s+s+2s
Collect like terms: 4s+ 12 + 2s
Simplify: 6s+12
Bring back into a full equation: 6s+12=102
Simplify= 102-12=6s
90= 6s
90/6=s
s=15
Then bring back into sides: Left side and right sides are 15 as s= 15
15+6= 21 so both top sides are 21
2×15=30
So it goes in the order from left to bottom clockwise:
15, 21, 21, 15, 30

Answer:
12-5xy and 5r-7
Step-by-step explanation:
solve: 8+2x-12=58
i need help please asap.
Answer: x=31
Step-by-step explanation:
-4 + 2x=58
2x-4=58
2x-4+4=58+4
2x=62
2x/2=62/2
x=31
Answer:
x = 31
Step-by-step explanation:
- Combine all like terms;
8+2x-12=58
2x -4 = 58
- Add 4 to both sides.
2x = 62
- Divide both sides by 2.
x = 31
Which inequality is true?
C, because π ≈ 3,14 so 9π = 9 · 3,14 = 28,26 > 27
1+sinx+cosx/1+sinx-cosx=1+cosx/sinx help pls by proving
Answer:
Below.
Step-by-step explanation:
I'll write sin x as s and cos x as c so we have:
(1 + s +c)/(1 + s - c) = (1 + c)/s
Cross multiplying:
s + s^2 + cs = 1 + s - c + c + cs - c^2
s + s^2 + cs = 1 + s + cs - c^2
s^2 + c^2 + s - s + cs - cs = 1
s^2 + c^2 = 1.
- that is sin^2 x + cos^2 x = 1 which is a known identity.
Therefore the original identity is proved.
