Start by combining like terms on both sides

-6+3=-3

Now we have:

To isolate g we need to subtract 12 from both sides -18-12= -30

Now we have

Divide both sides by -3 to isolate g, now we have:

When we divide an inequality by a negative we flip the sign so:

becomes:

**Answer:**

**(3.95m) + (8.95b) = 47.65**

**Step-by-step explanation:**

Hugh bought some magazines that cost = $3.95 each

the cost of each books = $8.95

He spent a total on purchase of books and magazines = $47.65

Let m represent the number of magazines and b represent the number of books.

Now the equation will be

**(3.95m) + (8.95b) = 47.65**

Simplifying

3x + -4y = 16

Solving

3x + -4y = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

3x + -4y + 4y = 16 + 4y

Combine like terms: -4y + 4y = 0

3x + 0 = 16 + 4y

3x = 16 + 4y

Divide each side by '3'.

x = 5.333333333 + 1.333333333y

Simplifying

x = 5.333333333 + 1.333333333y

3x + -4y = 16

QUESTION POSTED AT 29/01/2020 - 05:22 PM

To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20

It has to be equated to zero and the values of x are the x-intercepts. So,

4x2 – 24x + 20 = 0

The resulting equation is a quadratic equation which can be solved by different methods. The solution is

x = 5, 1

The average therefore is:

-3(y-5) = 24...distribute through the parenthesis

-3y + 15 = 24....subtract 15 from both sides

-3y = 24 - 15

-3y = 9...divide both sides by -3

y = 9/-3

y = -3

-3y + 15 = 24....subtract 15 from both sides

-3y = 24 - 15

-3y = 9...divide both sides by -3

y = 9/-3

QUESTION POSTED AT 29/01/2020 - 05:17 PM

**Answer:**

The correct answer is **C.**

**Step-by-step explanation:**

Notice that the difference between consecutive values of x is always 1, and the difference between consecutive values of y is always 2. This means that

where and stands for two consecutive values of x, and the same goes to y.

Now, notice that this is the definition of the slope of the equation of a line. Then, a line can be characterized by this condition, and that is why **C ** is the correct answer.

Anyway, you can check that this set of point is generated by a linear function in other way. Suppose that it can be done, and the linear function has the form

.

From the pair (0,7) we deduce that , then . Now, substituting the pair (-3,1) we get and as consequence . Thus, if the points are generated by a linear function, its expression would be .

Now, substitute the different values of x and check that the same values of y are obtained.

QUESTION POSTED AT 29/01/2020 - 05:16 PM

**Answer:**

The correct option is B.

**Step-by-step explanation:**

It is given that the ordered pairs below represent a linear relation between x and y. (-3,0), (-2,4), (-1,8), (0,12), (1,16), (2,20).

At y-intercept the value of x is 0. From the given points we can say that the y-intercept of the function is (0,12).

If a line passing through the two points, then the slope of the function is

The slope of the function is

**Therefore the slope of the line represented by this table is 4 and the y-intercept is 12. Option B is correct.**

**Answer:**

**Step-by-step explanation:**

THe sequence 64,16,4,1 as you can see it´s actually going down or decreasing, so the ratio should be a fraction, in order to find that you just have to pair two terms that are next to eachother in the sequence to find the fraction, let´s try it with the first two: 64 and 16:

So the ratio is 1/4. You can confirm the ratio by using other numbers in the sequence, like the last two:

This is the ratio directly.
