Problem 3
Murljashka [212]

Answer:

-\frac{2}{5}

Step-by-step explanation:

Given expression:

           2x + 5y = -10

The equation of a straight line is;

            y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

 Now;

          let us write the given expression in slope intercept format;

            2x + 5y  = -10

                    5y = -2x - 10

                     y = -\frac{2x}{5}  - 2

So, the slope of the line is -\frac{2}{5}

What is the explict formula for the arithmetic sequence -7.5,-9,-10.5,-12
elena-14-01-66 [18.8K]

Answer:

<u>x = -7.5 - 1.5(n−1) </u>

Step-by-step explanation:

the explicit formula for the arithmetic sequence has the form

x = a + d(n−1)

a is the first term and d is the common difference

The given arithmetic sequence is

-7.5,-9,-10.5,-12

The first term is -7.5

d = common difference = -9 - (-7.5) = -1.5

∴ x = -7.5 - 1.5(n−1)

Two functions, f and g, are represented by these function machines.
Gennadij [26K]

Answer:

x = -2

Step-by-step explanation:

Since we know they will have the same output, we can set them equal to each other in an equation. We'll use x to represent the input.

3x + 6 = 8(x + 2) (Given)

3x + 6 = 8x + 16 (Distributed the 8)

6 = 5x + 16 (Subtracted 3x on both sides)

-10 = 5x (Subtracted 16 on both sides)

-2 = x (Divided 5 on both sides)
