A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36

B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B

distance between 2 points x and y is |x-y|

so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68

Norma made quilts and sold them at a craft show. The cost of fabric for each quilt was $13.55. She sold each quilt for $35. The

CaHeK987 [17]

Answer:

least number of quilts is gonna be 10

Step-by-step explanation:

ok...so profit = revenue - expenses

n = # of quilts

revenue : (the money made from the quilts)

she sold each quilt for 35 bucks......35n

expense : (the money Norma spent on the materials)

the cost of fabric is 13.55 per quilt......13.55n

so ur expression is :

revenue - expenses

35n - 13.55n <==== this is part A

==========================

she wants to make a profit of 200...

P = revenue - expenses

200 = 35n - 13.55n

200 = 21.45n

200 / 21.45 = n

9.32 = n.......gonna have to round up to 10 <==== part B

ok...so 9 quilts is not gonna be quite enough...so shes gonna have to make 10.

I don’t know how to solve this

Colt1911 [192]

Answer:

x=0, -3/4

Step-by-step explanation:

We can solve by factoring. We will factor by GCF the greatest common factor. $8x^2$ and $6x$ share several factors in common:

they both share an x
they both share 2

I pull out 2x and I get $2x(4x+3)=0$ . I now set each factor equal to 0 and solve for x.

2x=0

x=0

4x+3=0

4x=-3

x=-3/4

Select the correct answer. If the zeros of a quadratic function are 3 and 8, what are the factors of the function? A. (x + 8) an

almond37 [142]

Answer:

C. (x-8) and (x-3)

Step-by-step explanation:

When we calculate the zeros of a function, we are calculating the points where that function crosses the x axis, and to do so we have to equal the function to zero and isolate X.

$(x - 3) . (x-8) = 0$

The only way a multiplication can have a result of 0, is that any of it's factors were equal to zero. So we can take both factors and equal them to zero and isolate x to know the function's zeros.

$(x - 3) = 0\\x = 3$
