5 0

Answer:

(f - g)(x) = 3^{x} + 8x + 4

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3^{x} + 10x - (2x - 4) ← distribute parenthesis by - 1

= 3^{x} + 10x - 2x + 4 ← collect like terms

= 3^{x} + 8x + 4

Answer:

R1:   Given

R2:   Subtraction Property of Equality

R3:   Distribute Property

R4:   Addition Property of Equality

R5:   Division Property of Equality

Write a paragraph proof for the following conjecture: m∠1 + m∠2 = m∠4

Prove: m∠3 + m∠1 + m∠2 = 180°

Given: ∠1 + ∠2 = ∠ 4

∠4 + ∠3 must be 180° because they are supplementary

If ∠4 + ∠3 is 180, and ∠1 + ∠2 = ∠4, you can substitute ∠4 in the first equation for ∠1 + ∠2.

Hence, we arrive at the answer ∠1 + ∠2 + ∠3 = 180.

What is the solution of
Artemon [7]

Yo sup??

we can simply try option verification for this problem.

when x=0 we get,

1 and 1≠5 therefore x=0 is not a solution.

when x=1 we get

√6-1≠5 therefore x=1 is not a solution.

when x=16 we get

9-4=5 therefore x=16 is a solution

Hence the correct answer is option C

Hope this helps.
