Hey there!

GUIDE #1

• 2 Negatives = POSITIVE

• 2 Positives = POSITIVE

• 1 Negative & 1 Positive = NEGATIVE

• 1 Positive & 1 Negative = NEGATIVE

• NEGATIVES are on the LEFT SIDE of the number line

• POSITIVES are on the RIGHT SIDE of the number line

GUIDE #2

• DIFFERENCE means SUBTRACT/SUBTRACTION

• SUM means ADDITION/ADD

• PRODUCT means MULTIPLY/MULTIPLICATION

• QUOTIENT means DIVISION/DIVIDE

-30 - (-10)

= -30 + 10

YOU START AT -30 and go up 10 spaces to the RIGHT

= -20

Therefore, your answer is: -20

If AB=BC,AB=4=4x-2,andBC=3x+3,fine the length of AB
laila [671]

Answer:

18

Step-by-step explanation:

First, I'm assuming AB=4=4x-2 was a typo and it's supposed to be AB = 4x - 2

AB=BC

AB = 4x - 2 BC = 3x + 3

4x - 2 = 3x + 3

Solve for x Add 2 to each side

4x - 2 = 3x + 3

4x - 2 + 2 = 3x + 3 + 2

4x = 3x + 5 Subtract 3x from each side.

4x - 3x = 3x- 3x + 5

4x - 3x = 5

x = 5

Now plug back in to the original equations

AB = 4x - 2                  BC = 3x + 3

AB = 4 (5) - 2               BC = 3(5) + 3

AB = 20 - 2                  BC = 15 + 3

AB = 18                        BC = 18

So AB is 18

Jenna knits scarves and then sells them on Etsy, an online marketplace. Let C(x) = 4x + 20 represent the cost C in
Alex Ar [27]

Answer:

Step-by-step explanation:

We are given that Jenna knits scarves and sells them on Etsy an online market place.

C(x)=4x+20

Where C=Represents the cost in dollars

x=Number of scarves

We have to create a table to show the relationship between the number of scarves x and the cost C

Substitute x=1

C(1)=4(1)+20=$24

Substitute x=2

C(2)=4(2)+20=$28

C(3)=4(3)+20=$32

C(4)=4(4)+20=$36

C(5)=4(5)+20=$40

C(6)=4(6)+20=$44

If line AD is a tangent to circle B at point C, and m∠ABC = 55º, what is the measure of ∠BAD?
alexandr1967 [171]
None of those.  ∠BAD = 180º - 90º - 55º = 35º, because ABC is a right triangle.
