Twelve is added to the product of a number and 5. The result is -3. Find the number. And write an equation for this. SHOW FULL W

Free_Kalibri [48]

Let the number be x

Equation:

12 + 5x = -3

Answer: The equation is 12 + 5x = -3

Solve it:

5x = -3 - 12

5x = -15

x = -15 ÷ 5

x = -3

Answer: The number is -3.

Teresa graphs the following 33 equations: y=2xy=2x, y=x2+2y=x2+2, and y=2x2y=2x2. She says that the graph of y=2xy=2x will event

Neko [114]

The correct question is
<span>Teresa graphs the following 3 equations: y=2x, y=x2+2, and y=2x2. She says that the graph of y=2x will eventually surpass both of the other graphs. Is Teresa correct? Why or why not?

we have that
y=2x
y=x</span>²+2
y=2x²

using a graph tool
see the attached figure

<span>We can affirm the following
</span>the three graphs present the same domain-----> the interval (-∞,∞)

The range of the graph y=2x is the interval (-∞,∞)

The range of the graphs y=x²+2 and y=2x² is the interval [0,∞)

therefore
<span>Teresa is not correct because the graph of y = 2x will not surpass the other two graphs since in the interval of [0, infinite) the three graphs present the same range</span>

Given: If x, then not y, if not y, then z.<br> Y is true. So:

Fed [463]

If x, then not y, if not y, then z. Y is true. So: X is true, Z is True

<h3>How to Interpret Conditional Statements?</h3>

A conditional statement is a type of structure to express the relationship between two dependent variables. Its structure is as follows:

If P, then Q...

Now, from the question we are told that;

If x, then not y, if not y, then z.

Y is true. So:

Now, when looking at conditional statements in depth, and comparing to this question we can easily see that since Y is true, then it means that if X is true, then Z is also true.

Thus,

If x, then not y, if not y, then z.

Y is true. So: X is true, Z is True

When x=3, y=16 and when x=6, y=8. Which inverse variation equation can be used to model this function

MakcuM [25]

Inverse variation equations take the following form:

y = a/x, where a is some constant

We know x=3, y=16 and x=6, y=8 satisfy the equation.

Let's find the value of a.

16=a/3

Multiply both sides by 3

16*3 = a

48 = a

Thus, the equation is:

y = 48/x

You can use the other values of x and y to test, but I'm sure this is the correct equation. :)

Solve for x in both!!!!!

zvonat [6]

Answer:

$- 2(x - 2) - 4x = 3(x + 1) - 9x \\ - 2x + 4 - 4x = 3x + 3 - 9x \\ 9x - 3x - 2x - 4x = 3 - 4 \\ 9x - 9x = - 1 \\ 0x = - 1 \\ 0 = - 1$

So ; No solution

___o___o____

$5(x + 2) - 3 = 3x - 8x + 7 \\ 5x + 10 - 3 = - 5x + 7 \\ 5x + 7 = - 5x + 7 \\ 5x + 5x = 7 - 7 \\ 10x = 0 \\ \\ x = \frac{0}{10} \\ \\ x = 0$

I hope I helped you^_^
