Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation. Point Form: ( 8 , − 3 ) Equation Form: x = 8 , y = − 3

Let G be a connnectde graph with n vertices and m edges. supposed also that m = n. prove that G contains exactly one cycle

ElenaW [278]

Answer:

Contradiction

Step-by-step explanation:

Suppose that G has more than one cycle and let C be one of the cycles of G, if we remove one of the edges of C from G, then by our supposition the new graph G' would have a cycle. However, the number of edges of G' is equal to m-1=n-1 and G' has the same vertices of G, which means that n is the number of vertices of G. Therefore, the number of edges of G' is equal to the number of vertices of G' minus 1, which tells us that G' is a tree (it has no cycles), and so we get a contradiction.

Use the compound interest formula to compute the total amount accumulated and the interest earned.

mezya [45]

A=3,500×(1+0.011÷12)^(12×4)
A=3,657.36

Interest earned
=3657.36-3500=157.36

Can you solve the inequality 2(x-3) is less than or equal to 10 without using the distributive property? Explain.

STatiana [176]

Answer:

Yes, without using the distributive property, we get the value for the given expression 2(x - 3) ≤ 10 as x ≤ 8

Step-by-step explanation:

Here, the given expression is:

2(x - 3) ≤ 10

Yes, the given expression can be solved without using the DISTRIBUTIVE Property

Here, consider the given expression:

2(x - 3) ≤ 10

Now, divide the inequality by 2 on both sides, we get:

$\frac{2(x-3)}{2} \leq \frac{10}{2}\\\implies (x - 3) \leq 5$

Now adding (+3) on both the sides, we get:

(x - 3) ≤ 5 ⇒ (x - 3 + 3 ) ≤ 5 + 3

or, x ≤ 8

Hence, without using the distributive property, we get the value of x ≤ 8 for the given expression 2(x - 3) ≤ 10
