Answer:
Step-by-step explanation:
First, note that
And using the chain rule in one variable
Now remember that the chain rule in several variables sates that
Therefore the chain rule in several variables would look like this.
5(2x-3)+7
distribute the 5 to the 2x and -3
10x-15+ 7
combine like terms -15+7
10x-8
Answer:
∠1 = 73
∠2 = 107
∠4 = 107
Step-by-step explanation:
∠1 and ∠3 are vertical angles
Vertical angles are congruent
Which means that because ∠3 = 73°, ∠1 also equals 73°
∠2 and ∠3 are supplementary angles
supplementary angles add up to equal 180
Thus, ∠2 + ∠3 = 180
If ∠3 = 73° then ∠2 + 73 = 180
180 - 73 = 107
Hence, ∠2 = 107
∠2 and ∠4 are vertical angles
Like stated previously vertical angles are congruent
Which means that because ∠2 = 107°, ∠4 also equals 107°
I think it's 74 because 3 has the factor :1,3
53 has the factor: 53,1
73 has the factor:1 ,73
74 has the factor:1,74,2,37
Answer:
-108
Step-by-step explanation:
4xy^3
Let x =-1 and y = 3
4*(-1) * 3^3
PEMDAS says exponents first
4 *(-1) * 27
Then multiply
-108
