The first step would be to divide both sides by 2...because u want to get the absolute value on one side, and everything else on the other side
2 | x + 5 | = 16...divide both sides by 2
| x + 5 | = 16/2
| x + 5 | = 8
u would then solve x + 5 = 8 and x + 5 = -8 for ur answers
Hey! Great to see you again.
Based on what we learned last time, we can apply it to this equation!
Solve 3x+y =−5 for y:
3x+y=−5
3x+y+−3x=−5+−3x Let us add -3x to both sides.
y=−3x−5.
Substitute −3x−5 for y in −2x+3y=18:
−2x+3y=18
−2x+3(−3x−5)=18
−11x−15=18 Simplify both sides :)
−11x−15+15=18+15 Add 15 to each side.
−11x=33
x = -3
Now solve for y.
−3 for x in y=−3x−5:
y=(−3)(−3)−5
Can you solve this equation? Let me know if you need help, tell me what you get! :) That will be your y answer. :D
Have a great one!
The answer is b; quadrant 2. starting in right corner and going counterclockwise
Answer:
Breadth = 8 cm
Length = 17 cm
Step-by-step explanation:
Given rectangle:
Breadth = x cm
Length = x + 9 cm
Area = length * breadth
= x * (x + 9)
= x² + 9x
Rectangle with length and breadth increased:
Breadth = x + 3 cm
Length = x + 9 + 3 = x + 12 cm
Area = 84 + (x² + 9x) cm²
(x +3) * (x +12) = 84 + x² + 9x
Use FOIL method
x*x + x*12 + 3*x + 3*12 = 84 + x² + 9x
x² + 12x + 3x + 36 = 84 + x² + 9x {add the like terms}
x² + 15x + 36 = 84 + x² + 9x
x² + 15x + 36 - 84 - x² - 9x = 0
6x - 48 = 0
6x = 48
x = 48/6
x = 8
Breadth = x = 8 cm
Length = x + 9 = 8 +9 = 17 cm
Answer:
14 =x
Step-by-step explanation:
We can use ratios to solve
5 loaves x loaves
------------- = ---------------
2.5 hours 7 hours
5 * 7 = 2.5 x
Divide by 2.5
35/2.5 = 2.5x/2.5
14 =x
