The function rule for the equation y = -5x - 1 is
(x,y) ⇒ (0,-1) , (-1,4) , (3,-16)
<h3>What is dependent variable and independent variable ?</h3>
In a mathematical equation independent variable is set by us to examine the give equation or function how it is behaving or it's value for a specific value being set by us.We can also think of independent variable as the input to a function and dependent variable as the output.
According to the given question
y = -5x -1 the table is illustrated below
x -2 -1 0 1 2 3
y 9 4 -1 -6 -11 -16

The answer is (-2, -1.5, 0, 2/5, 3/4)
Answer:
Step-by-step explanation:
-x + 2y = 8
-2x + y = -5
2x - 4y = -16
-2x + y = -5
-3y = -21
y = 7
-x + 14 = 8
-x = -6
x = 6

Answer: 336 cm²
Step-by-step explanation:
A trapezoid looks like a rectangle with 2 traingles attached to the side, yeah? So imagine cutting off those 2 triangles. In the middle you have a rectangle with the dimensions of 14 cm by 16 cm. The area of that rectagle is 224 cm². By subtracting the top base length from the bottom base length, you get the length of the two triangles. So, it would be 28 cm - 14 cm, giving you 14 cm. There were 2 triangles, so cut that length in half and you get 7 cm for the base of one traingle. To find the area of 1 traingle, you would do 1/2 multiplied by 7 multiplied by 16. But you have 2 triangles. so the 1/2 step isn't needed because if you put the two triangles together, you get a new rectangle. Thus, when you add the area of this new rectangle, you get 112 cm². Add this to the original rectangle, and your final area is 336 cm².
X/4 +5/8 = 3/8
X/4 = 3/8-5/8
X/4 = (3-5)/8
X/4 = -2/8
Multiply both sides by 4 we get
4x/4 = -8/8
X = -1
