Answer:

1) 2x+7

2) -3x+11

3) 0.75x-2

4) -2x+0

5) -1.5x+2

6) -4x+16

Step-by-step explanation:

1) y = mx + c

m = 2 when x=1 , y=9

9 = 2(1)+c

c = 7

y = 2x + 7

2) m = -3

When x=4, y= -1

-1 = -3(4) + c

c = -1+12 = 11

y = -3x + 11

3) m = 0.75

When x= -4, y= -5

-5 = 0.75(-4) + c

-5 = -3 + c

c = -2

y = 0.75x - 2

4) m = (y2-y1)/(x2-x1)

m = (2-(-6))/(-1-3) = 8/-4 = -2

y = -2x + c

When x= -1, y= 2

2 = -2(-1) + c

2 = 2 + c

c = 0

y = -2x + 0

5) m = (-10-(-4))/(8-4)

m = (-10+4)/4 = -6/4 = -1.5

y = -1.5x + c

When x= 4, y= -4

-4 = -1.5(4) + c

-4 = -6 + c

c = 2

y = -1.5x + 2

6) m = (-4-4)/(5-3) = -8/2 = -4

When x= 3, y= 4

4 = -4(3) + c

4 = -12 + c

c = 16

y = -4x + 16

Determine which of the following situations requires the distributive property in order to simplify the expression. Select all s
ipn [44]

Answers

9(x + y)

(7 - a)(b)

 

The Distributive Property is used in algebraic expressions to multiply a single term and two or more terms which are inside a set of parentheses.

 

In the case of x(2y), there is only one term inside the parenthesis

In the case of 9(x ∙ y), the distributive property is not used because (x ∙ y) = xy which means only one term will be multiplied by the term outside the parenthesis (9)

 

In the case of 9(x + y), the distributive property is used because the two terms in the parenthesis (x and y) will be multiplied by the term outside the parenthesis (9)

9(x + y) = 9*x + 9*y (by applying the distributive property)

 

In the case of (7 ∙ a)(b), the distributive property is not used because (7 ∙ a) = 7a which means only one term will be multiplied by the term outside the parenthesis (b)

 

In the case of (7 - a)(b), the distributive property is used because the two terms in the parenthesis (7 and -a) will be multiplied by the term outside the parenthesis (b)

(7 - a)(b) = 7*b - a*b (by applying the distributive property)

 

In the case of (2 ∙ x) ∙ y, the distributive property is not used because (2 ∙ x) = 2x which means only one term will be multiplied by the term outside the parenthesis (y)

Which dot plot has the largest range?
romanna [79]

Answer:

Calico Crayfish has the largest range ⇒ The range = 9

Step-by-step explanation:

∵ The rang is the difference between the largest value

   and the smallest value

In the Calico Crayfish the largest value is 10 and the smallest value is 1

∴ The range = 10 - 1 = 9

In the Zebra Mussel the largest value is 10 and the smallest value is 2

∴ The range = 10 - 2 = 8

In the Blue-back Herring the largest value is 10 and the smallest value is 4

∴ The range = 10 - 4 = 6

In the Shield Darter the largest value is 9 and the smallest value is 2

∴ The range = 9 - 2 = 7

∴ The largest range is 9 in Calico Crayfish
