{(-3.7).(-5, -8), (-6, -1). (-9, -1), (0, -3) }
zhenek [66]

Answer:

The domain is the set of all the values of x, so it would be -3, -5, -6, -9, 0. The range would be every set of y, so it would be 7, -8, -1, -3. Finally, this relation is indeed a function.

Domain: -3, -5, -6, -9, 0

Range: 7, -8, -1, -3

Is it a function? Yes

4 questions! Write an equation in slope-intercept form for each of the following:
AysviL [449]
1) y= -4x+c

2) y= 3x+c replace x and y to find c , 5=3(2)+c
C= -1
Y=3x-1

3) find slope first m=y2-y1/x2-x1 = 0-(-1)/-2-1 = 1/-3 and now you have y= -1/3x+c to find c just replace any of the given points , 0= -1/3(-2)+c
C= -2/3 and so y= -1/3x-2/3

4) DO THE SAME STEP AS NUMBER 3 and enjoy!

1. K is the midpoint of HN. HK = 4x + 5 and<br> HN = 11x – 11. Solve for x and find KN.
galben [10]

Answer:

see explanation

Step-by-step explanation:

Since K is at the midpoint of HN then HK = KN = 4x + 5, thus

HN = HK + KN ← substitute values

11x - 11 = 4x + 5 + 4x + 5, that is

11x - 11 = 8x + 10 ( subtract 8x from both sides )

3x - 11 = 10 ( add 11 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Hence

KN = 4x + 5 = (4 × 7) + 5 = 28 + 5 = 33

How to do factor each expression 63 + 81
Katyanochek1 [597]

Answer:

9(7 + 9)

Step-by-step explanation:

To factor an expression you have to first find the highest common factor (HCF) of the numbers in the expression. You divide them by their HCF, bracket it and place the HCF outside the bracket.

63 + 81 =  \\  9(\frac{63}{9}  +  \frac{81}{9})  =  \\ 9(7 + 9)

To check if it is factored properly you can do the opposite of what you just did by clearing the bracket.

9 (7 + 9)

(9 x 7) + (9 x 9)

= 63 + 81
