Answer:

3

Step-by-step explanation:

Okay, since we know what <em>n</em> equals to, all we have to do is insert 6 where <em>n</em> was:

5(6+3)-7(6)

Now we just need to simplify, so:

30 + 15 - 42

45-42

And we get our answer

= 3

Answer:

3

Step-by-step explanation:

because if N = 6, then you will have to substitute the n to n and then do the order of operation. first it will be 6+3=9 and then 9*5=45. then you will do 7*6=42 and then subtract 45-42=3

PLEASE HELP ASAP!!! Fill in a two-column proof for the following conjecture. Use the reasons in the bank below, you will not use
notsponge [240]

Answer:

2. Given

3. Definition of supplementary angles

4. Substitution Property

5 Subtraction Property

Step-by-step explanation:

2. Given

We are given in the statement that m<1 = 112°

3. Definition of supplementary angles

Supplementary angles definition: Two angles are supplementary if there sum is equal to 180°. That statement states:

m<1 + m<2 = 180°

4. Substitution Property

We put the value of m<1 = 112° in the equation. This is substitution property.

5. Subtraction Property

To find the value of m<2 we subtract 112 from both sides of the equation.

This is subtraction property.

Determine the end behavior for function f(x)=-x^4+5x^3-3
Gnesinka [82]

Answer:

Step-by-step explanation:

The dominant term of this function is x^4.  The graph of x^4 starts in Quadrant II and continues in Quadrant I.

If we have y = -x^4, the graph starts in Quadrant III and continues in Quadrant IV.  This is the end behavior for f(x)=-x^4+5x^3-3.

For how many integer values of n will the value of the expression 4n + 7 be an integer greater than 1 and less than 200?
Morgarella [4.7K]

Answer:

48

Step-by-step explanation:

We are asked that the value of (4n + 7) will be an integer > 1 and < 200, for how many integer values of n.

So, equating (4n + 7) with 200 we can get the value.

4n + 7 = 200

⇒ 4n = 193

⇒ n = 48.25

Hence, the value of n will be the largest integer less than 48.25.

Therefore, the number of integer values of n will be 48. (Answer)
