3 0

Answer:

In three years, cost (Value) = 47.70

Step-by-step explanation:

When the decrease is relative to the last value, it is exponential.

Depreciations are usually exponential.

In three years,

Value = 70*(1-0.12)^3

= 47.70

Fill in the blank with a constant, so that the resulting expression can be factored as the product of two linear expressions: 2a
sdas [7]

Answer:

-15

Step-by-step explanation:

We proceed as follows;

In this question, we want to fill in the blank so that we can have the resulting expression expressed as the product of two different linear expressions.

Now, what to do here is that, when we factor the first two expressions, we need the same kind of expression to be present in the second bracket.

Thus, we have;

2a(b-3) + 5b + _

Now, putting -15 will give us the same expression in the first bracket and this gives us the following;

2a(b-3) + 5b-15

2a(b-3) + 5(b-3)

So we can have ; (2a+5)(b-3)

Hence the constant used is -15

I need help with this ^
Gelneren [198K]

Answer:

15=a

Step-by-step explanation:

how I got this is because a triangle is equal to 180 so you have to add all of the things together then you get 12a=180 the reason why I got this is because if you add it so 6x+3a-1+3a+1 so you add common terms then you will equal to 12a then you divide it on both sides so then you equal to 15

Anna35 [415]

Answer:

y = 3x + 6

Step-by-step explanation:

Since the line is parallel, it has the same slope -- 3

y = 3x + b, sub point (1, 9)

9 = 3(1) + b

9 = 3 + b

b = 9 - 3

b = 6

y = 3x + b -- y = 3x + 6
