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!
Answer:
327
Step-by-step explanation:
You will plug in the -3 for x. 6 times -3 equals -18. -18 squared equals 324. 324 minus -3 equals 327.
First of all, the answer is x=0. Second, lets go through the steps
First, Simplify both sides of the equation
Second Add 6x to Both Sides
Third, add 4 to both sides
Fourth, Divide both sides by 11.
You get 0/11, so X=0
Hope this helps!
Answer:
The area of the rectangular area is (1400w-w²) square yards.
Step-by-step explanation:
Given that,
David has available 2800 yards of fencing. He wants to enclose a rectangular area.
Assume that, the length and width of the rectangular be l and w respectively.
The perimeter of the rectangular area is
=2(length+ width)
=2(l+w)
So,
2(l+w)= 2800
The area of the rectangular area is = length× width
=l×w
=(1400-w) w
=(1400w-w²) square yards.
