Write an equation of a line that goes through the point (-9, 3), and is perpendicular to the line 3x + y = 5
Vlad [161]
To find the slope of the line, first find the slope of 3x + y = 5, and then its opposite reciprocal.

3x + y = 5
y = -3x + 5
the slope of 3x + y = 5 is -3.

the slope is -3, so the opposite reciprocal slope is 1/3.

the equation of any line is y = ax + b
to find this line, y = 3, x = -9, and the slope is 1/3.

3 = -9a + b
3 = -9 (1/3) + b
3 = -3 +b
b = 6

substitute a and b into the equation
y = ax + b
y = 1/3x + 6

the equation of the line is y = 1/3x + 6.

Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equ
butalik [34]

Answer: The required point = (1.857,8.643)

Step-by-step explanation:

Equation of circle with center (h,k) and radius r: (x-h)^2+(y-k)^2=r^2

Given: Radius = 5 , center = (0,4)

Eqation of circle: (x-0)^2+(y-4)^2=5^2

x^2+(y-4)^2=25

x^2+(2.5x+4-4)^2=25  [Using equation y = 2.5 x + 4  ]

x^2+(2.5x)^2=25

x^2+6.25x^2=25

7.25x^2=25

x^2=3.44827586207

x=1.857

y= 2.5(1.857)+4

=8.6425

Hence, the required point = (1.857,8.643)

Is {(3,4),(3,5),(4,4), (4,5)} a function
Sholpan [36]

Answer:

<u>No, it's not a function.</u>

Step-by-step explanation:

This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. <u>Therefore, this is not a function.</u>
