DanielleElmas [232]3 years ago
7 0

Answer:

x = ±sqrt(7)

Step-by-step explanation:

x^2 - 8 = -1

Add 8 to each side

x^2 - 8+8 = -1+8

x^2 = 7

Take the square root of each side

sqrt(x^2) = ±sqrt(7)

x = ±sqrt(7)

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.
SCORPION-xisa [38]

The equation of line is:

y = \frac{-3}{2}x+1

Further explanation:

The standard form of equation in point-slope form is:

y = mx+b

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

y = \frac{-3}{2}x+b

To find the value of b, putting the given point (4,-5) in equation

-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1
