The answer would be -7.

7 - (-4) - 18 (Simplify 3 * (-6) to -18)

7 + 4 - 18 ( Simplify brackets )

-7 (Simplify).

That is true because the square root of 32 is about 5.66, so 4.65 IS less than it.

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
NeTakaya

Answer:

y = -x - 4

Step-by-step explanation:

First find the slope

y - 4 = (x - 6)

y - 4 = x - 6

y = x - 6 + 4

y = x - 2 (y = mx + C)

Slope m = 1

It is said that the line is perpendicular to a point ( -2, -2)

If two lines are perpendicular, their slope will be negative reciprocal

The negative reciprocal of slope = 1 is -1

Using a slope intercept form as requested by the question

y = mx + C

Inserting the values given

(-2, -2)

We are using point slope form

y - y_1 = m ( x - x_1)

x_1 = -2

y_1 = -2

m = -1

Insert the values

y - ( -2)) = -1( x - (-2))

y + 2 = -1 ( x + 2)---- point slope form

But we are requested to give the answer in slope intercept form

y = mx + C

We have to open the bracket

y + 2 = -1(x + 2)

y + 2 = -x - 2

y = -x - 2 - 2

y = -x - 4 ( slope - intercept form)

Consider the following system of equations:
Mashutka [201]

Answer:

Liney=-2x+3 intersects line y=x-5

Step-by-step explanation:

We are given that

y=-2x+3

y=x-5

Subtract one equation from other then we get

-3x+8=0

3x=8

x=\frac{8}{3}

Substitute the value of x in first equation then we get

y=-2(\frac{8}{3})+3=-\frac{16}{3}+3=-\frac{-7}{3}

Hence, the solution (\frac{8}{3},-\frac{7}{3}) is the intersection point of two line  equations .

Answer:Liney=-2x+3 intersects line y=x-5
