Differentiat each
dy/dx 5x-6=5
dy/dx x^2-2=2x
dy/dx 4x=4
domain will be all real numbers because the derivitives won't make any wierd values like divisiono by 0 or square roots of negatives
so ya, it is the last one
Answer:
Step-by-step explanation:
They are equivalent. Use the distributive property.
3(x+3)
the 3 on the outside of the parenthesis is multiplied by the variable(the letter) and thenthe constant(number) inside the parenthesis.
makes and equivalent equation 3x+9
One way is subsitute
I like solving
so
what you do is this
add the equaitons to gether to eliminate x
2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5
sub back
2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x
the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)
I think they wanted you to read the garph you should have attached and guess the answer
the closes one is
hmm, x=-3
and y=1
so then D is the answer
Answer:
f(2) = (-2)
Step-by-step explanation:
f (x) = 5x -12
f(2) = 5 * 2 - 12
= 10 - 12
= (-2)
