From 1985 to 2007, the number B B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 B(t)=-329.4t+1

3747 where t is the year and t=0 corresponds to 1985. How many federally insured banks were there in 1990?

Answer:

12100

Step-by-step explanation:

If the number B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 from 1985 to 2007 where t = 0 correspond to year 1985

In order to determine the amount of federally insured banks that were there in 1990, we will first calculate the year range from initial time 1985 till 1990

The amount of time during this period is 5years. Substituting t = 5 into the modeled equation will give;

B ( t ) = − 329.4 t + 13747

B(5) = -329.4(5) + 13747

B(5) = -1647+13747

B(5) = 12100

This shows that there will be 12100 federally insured banks are there in the year 1990.

Whats the GCF of 49 and 4
Irina18 [472]
The greatest common factor is 1 because there is not a number that goes into or will multiply and get 49 and 4. 49 is an odd number and 4 is an even number so the GCF is 1.

Select the inequality that corresponds to the figure:
vivado [14]

Answer:

C. 2x-y>-7

Step-by-step explanation:

The Line is not part of the region since is drawn in the graph using a dotted line, but we still need to find its equation.

The equation of a line is y=mx+b, where 'm' is the slope.

'm' can be obtained using the following formula.

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

To find the slope, as well 'b' we need points from the line, those will be (-6,-5), (0,7) as (x2,y2) and (x1,y1) respectively

Evaluating those point in the formula we have 'm' =2

Using now the above result and the point (0,7) in the equation y=mx+b, we obtain the value for 'b'.

7=2*0+b7

b=7

Hence our line is y=2x+7, and if we write it in standard form we obtain the following> y-2x=7.

Now, since our line is not part of the region, and the region is below that line, there is the < sign.

Hence the inequality that corresponds to the figure is y-2x<7 or, if we multiply by -1 (changin orientation of signs)   2x-y>-7

Write equivalent expressions of 18m+42n​
serious [3.7K]

Answer:

See explanation

Step-by-step explanation:

Given:

18m + 42n

These two variables are not the same, so we can't add the two terms. However, we can factor out a number out of this expression.

The GCF of 18 and 42 is 6.

We can draw 6 out of this expression to get 6(3m + 7n).

This is an equivalent expression.

We can also draw 2 out to get 2(9m + 21n).

We can also draw 3 out to get 3(6m + 14n).

We can also draw 1/2 out to get (1/2)(36m + 84n).

There are endless possibilities, but these are a few. You get the idea!
