Answer:

y = -3/2x + 13

Step-by-step explanation:

    In order for a line to be perpendicular, it must have an opposite reciprocal slope to the given line. In this instance, the opposite reciprocal of 2/3 would be -3/2. Insert the information given into the point-slope formula.

y-7=-\frac{3}{2}(x-4)\\\\y-7=-\frac{3}{2}x+6\\\\y=-\frac{3}{2}x+13

Answer: y=-3/2x+13

Step-by-step explanation:

(4,7)   m=2/3

x,y     m⊥=-3/2

7=-3/2(4)+b

7=-6+b

13=b

y=-3/2x+13

Solve the given system of equations <br> 2x+8y=5<br> 24x-4y=-15
oee [108]

The value of x and y is y= 3/4 and x= -1/2

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given equations:

2x+8y=5........(1)

24x-4y=-15...........(2)

Multiply equation (1) by 12, we get

24x + 96y = 60.....(3)

From (2) and (3), we get

-4y-96y= -15-60

-100 y= -75

y= -75/-100

y= 3/4

and 2x+8y=5

2x + 8 (3/4) =5

2x + 6 = 5

2x= -1

x= -1/2

If f(x) = [x] – 5, what is f(8.6)?<br> 3<br> 4<br> 8<br> 9
shutvik [7]

Answer:

Step-by-step explanation:

The strange thing about the greatest integer function is that the number you are evaluating the function at is not actually the number unless its an integer.  The rule is to round down, ALWAYS, if you are dealing with a value of x that is not an integer.  In other words, you are NOT evaluating the function at 8.6, you have to round down to 8 and evaluate it there.  8 - 5 = 3
