Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
How am I supposed to know that the government is not a good idea to have a good time to time and money on what will be an important purchase of a new era of the most important things to do in the future and the other is a great way 345
constant term in any function is the term whose value does not change on variation of other parameters or in other case. We can also say constant term is independent of variable parameters.
take example
y = x + 3
here 3 is constant term which will not change either I change x or y . 3 is independent . it's just helps equation to hold information that overall in equation its matter.
so in given problem -4 is the constant
Hello,
f(x)-f(a)= -3x²-5x+1-(-3a²-5a+1)=-3(x²-a²)-5(x-a)=-3(x-a)(x+a)-5(x-a)
=-(x-a)(3(x+a)+5)
=-(x-a)(3x+3a+5)
lim (f(x)-f(a))/(x-a)=- lim (3x+3a+5)=3a+3a+5=-6a-5
if a=1==>-6*1-5=-11
Otherwise
f'(x)=-6x-5
f'(1)=-6-5=-11
