Fynjy0 [20]

Answer:

Step-by-step explanation:

1. Interchange x and y. We get: x = y^2 - 5

2. Solve for y: y^2 = x + 5, so that y = ±√(x + 5)

What is the slope of the line in the graph? answer fast help plzzz

ziro4ka [17]

The slope can be found by using the slope formula.

Slope = y2 - y1 / x2 - x1

First, we need two points on the line.

(-1, 0) and (0, 1)

x1 = -1 and y1 = 0

x2 = 0 and y2 = 1

Let's plug these values into our slope formula.

(1 - 0) / (0 - (-1)) = 1 / 1 = 1

The slope is 1

Does x equal if the problem is negative x -4x - 7 equals 5 negative 2X

Sphinxa [80]

Answer:

X = - 4

Step-by-step explanation:

Given in problem

- x -4x - 7 = 5 -2x

Or, -5x - 7 = 5- 2x

Or, -5x + 2x = 5 + 7

Or, -3x = 12

Or, x = - $\frac{12}{3}$

∴ X = - 4 Answer

Graph the line that represents a proportional relationship between yyy and xxx where the unit rate of change of yyy with respect

My name is Ann [436]

Answer:

$y=\frac{4}{3}x$

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m or unit rate of the line and the line passes through the origin

In this problem we have

$k=\frac{4}{3}$

substitute

$y=\frac{4}{3}x$

using a graphing tool
