Answer:

The equation in point-slope is \mathbf{y+5=3(x-6)}

Step-by-step explanation:

We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line y=-\frac{1}{3}x+4

The general form of point-slope is; y-y_1=m(x-x_1)

where m is slope and (x_1,y_1) is the point

We need to calculate slope.

We are given equation of line y=-\frac{1}{3}x+4 that is perpendicular to the required line.

The equation is given in slope-intercept form y=mx+b where m is slope.

Comparing both equations we get m= -1/3

But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e m=-\frac{1}{m}

<em>So, </em><em>slope of required line is m = 3 </em><em>(opposite reciprocal of -1/3)</em>

Now, the equation in point-slope form having slope m=3 and point (6,-5) is

y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)

So, The equation in point-slope is \mathbf{y+5=3(x-6)}

Can someone solve this please?

2x = 8 - 5y
x = 8/2 - 5y/2
x = 4 - 2.5 y
or
x = 4 - 5/2 y

&lt; B.5 14. Multiply &amp; simplify: (3x + 4)(x + 1)​
kondor19780726 [428]

Answer:

3x^2+7x+4

Step-by-step explanation:

Using FOIL (First, outer, inner, last)

First, we multiply 3x and x to get 3x^2 (First)

We then multiply 3x and 1 to get 3x (outer)

Then 4 and x to get 4x (Inner)

Then multiply 1 and 4 to get 4 (last)

Since the quadratics are all positive, we add all the terms together to get:

3x^2+3x+4x+4. Since 3x and 4x are like terms, we add them together and simplify to get:

3x^2+7x+4

And since we can't simplify any further, that's our answer!

Hope this helps :D
