How do I solve: 3(x+4)=3

2 answers:

8 0

In order to solve this, start by distributing the 3.

Essentially, we multiplying each value inside the parenthesis by 3, to get:

3x + 12 = 3

Next, subtract 12 on both sides:

3x + 12 - 12 = 3 - 12

12 - 12 = 0
3 - 12 = -9

So:

3x = -9

The last step here is to divide both sides by 3:

3x ÷ 3 = -9 ÷ 3

3 • X ÷ 3 = X
-9 ÷ 3 = -3

So, long story short, X = -3

3x + 12 = 3

(multiply 3 by the variables in the parentheses)

3x + 12 = 3

add 12 to each side

3x = 15

divide each side by 3

X=5

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = ln x, [1,7] choose one letter t

inn [45]

ANSWER

B.Yes, f is continuous on [1, 7] and differentiable on (1, 7).

$c\approx 3.08$

EXPLANATION

The given

$f(x) = ln(x)$

The hypotheses are

1. The function is continuous on [1, 7].

2. The function is differentiable on (1, 7).

3. There is a c, such that:

$f'(c) = \frac{f(7) - f(1)}{7 - 1}$

$f'(x) = \frac{1}{x}$

This implies that;

$\frac{1}{c} = \frac{ ln(7) - 0}{6}$

$\frac{1}{c} = \frac{ ln(7)}{6}$

$c = \frac{6}{ ln(7) }$

$c\approx 3.08$

Since the function is continuous on [1, 7] and differentiable on (1, 7) it satisfies the mean value theorem.

The table shows the number of championships won by the baseball and softball leagues of three youth baseball divisions organized

castortr0y [4]

Answer:

Step-by-step explanation:

heyq

The correct answer is:

7/10

Explanation:

Finding the totals of each column and row, we find:

There are 3+2+1 = 6 children in the baseball league.

There are 7+2+1 = 10 children in the softball league.

There are 3+7 = 10 children in the 7-9 division.

There are 2+2 = 4 children in the 10-12 division.

There are 1+1 = 2 children in the 13-15 division.

There are a total of 10+6 = 16 children.

We start with the information that the team is a member of the softball league. There are 10 children in this league; this is the denominator of the probability.

There are 7 children in the 7-9 division that are in the softball league. This gives us the probability 7/10.

please you are a student study well especially graph is easy thing to do.

Given: ABCD is a trapezoid, AC ⊥ CD , AB = CD, AC= square root of 75 , AB = 5 Find: Area of ABCD

Karolina [17]

How can its diagonal be perpendicular to one of its sides? Since this can be read out of your details! You know point A and C are not adjacent but C and D are. So, AC must be the diagonal which is never perp. to any of the sides (CD)
