What is the value of x in the solution to this system of equations? у + 2x = — 1 у = х +4

1 answer:

8 0

I believe the answer is -5/3

Y+2x=-1 could become y=-2x-1 and then set that and x+4 equal to each other -2x-1=x+4 and add 2x to both sides to get -1=3x+4 and subtract by 4 on both sides to get -5=3x then divide by 3 and get -5/3=x

Answer:

$\dfrac{1}{12}$

Step-by-step explanation:

Rewrite the denominators as products of factors, then cancel the common factors.

$\begin{aligned}\dfrac{5}{14} \times \dfrac{7}{30} & =\dfrac{5}{2 \cdot 7} \times \dfrac{7}{6 \cdot5}\\\\ & = \dfrac{5 \cdot 7}{2 \cdot 7 \cdot 6 \cdot 5}\\\\ & = \dfrac{1}{2 \cdot 6}\\\\ & = \dfrac{1}{12}{\end{aligned}$

Calculate the gradient of the line using rise/run method.

Lapatulllka [165]

Given:

The graph of line.

To find:

The gradient of the line using rise/run method.

Solution:

We know that the gradient of a line is also known as slope.

$Slope=\dfrac{Rise}{Run}$

Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.

$Rise=-3$

$Run=2$

Now,

$Slope=\dfrac{Rise}{Run}$

$Slope=\dfrac{-3}{2}$

The gradient of the line is $-\dfrac{3}{2}$ .

Therefore, the correct option is C.
