Answer:
A simplified/equivalent expression your equation would be - 8x + 10
Step-by-step explanation:
6(2x + 3) - 4(5x + 2)
Distribute:
= (6)(2x) + (6)(3) + (- 4)(5x) + (- 4)(2)
= 12x + 18 + - 20x + - 8
Combine Like Terms:
= 12x + 18 + - 20x + - 8
= (12x + - 20x) + (18 + - 8)
= - 8x + 10
Hope this helps!
This equation models exponential decay.
We know this because the exponent in the equation is negative, showing us that the growth is “negative”, meaning it represents decay.
Hope this helps!
Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!
