Seven times a number increased by three is 38

Answers

Answer 1

Answer: $n-the\ number\n\n7* n+3=38\n7n+3=38\ \ \ \ |subtract\ 3\ from\ both\ sides\n7n=35\ \ \ \ |divide\ both\ sides\ by\ 7\n\n\boxed{n=5}$

Answer 2

Answer: So,

If we translate this into mathematical form, we get
7n + 3 = 38

Subtract 3 from both sides
7n = 35

Divide both sides by 7
n = 5

Answer: 2b + -6

Step-by-step explanation: To simplify, we will use the distributive property.

Before distributing, I would change the -3 to plus a negative 3.

So we have 2(b + -3).

Now, distributing the 2 through the parenthses, we have 2(b) + 2(-3).

2(b) is 2b and 2(-3) is -6.

So we have 2b + -6 as our final answer.

Answer:

2b - 6

Step-by-step explanation:

2(b-3)=

Distribute

2*b - 2*3

2b - 6

When you graph an inequality, you used a closed dot when you use which
symbols?

Answers

You should only use a closed dot for the symbols ≤ and ≥.

When you should use a closed dot?

There are two types of dots used when graphing inequalities, closed and open.

We use closed dots when the value where the dot is, is a solution.
We use open dots when the velue where the dot is, is not a solution.

So, for exampe in:

x > 3.

We would put an open dot at 3, because the value x = 3 is not a solution, but all the values at the right of the 3 are solutions.

In the other hand, for:

x ≥ 3

Now 3 is in fact a solution, so here we should use a closed dot.

Then, answering the question.

"When you graph an inequality, you used a closed dot when you use which symbols?"

The ≤ and ≥ symbols.

If you want to learn more about inequalities, you can read:

You use a closed dot with the greater than or less than with the line under the symbol or the greater than or equal to or the less than or equal to symbols. The line indicates a closed dot.

What are the x-intercepts of the graph of the function f(x) = x2 + 4x – 12?(–6, 0), (2,0)
(–2, –16), (0, –12)
(–6, 0), (–2, –16), (2, 0)
(0, –12), (–6, 0), (2, 0)

Answers

Answer:

Coordinates are (–6, 0), (2,0).

Step-by-step explanation:

Given the function $f(x) = x2+4x-12$

we have to find the x-intercepts of the graph of the function f(x).

$y = x2+4x-12$

As the value of y coordinate is 0 on x-axis which gives the x-intercepts of the function.

Put y=0 in above function we get the x-intercepts.

$x^2+4x-12=0$

⇒ $x^2+6x-2x-12=0$

⇒ $x(x+6)-2(x+6)=0$

⇒ $(x-2)(x+6)=0$

⇒ x=2 and x=-6

Hence, x-intercepts are 2 and -6

⇒ Coordinates (–6, 0), (2,0).
