Answer:

[4 + 1] x [7 - 2] = 25

Step-by-step explanation:

When you have the brackets around [4 + 1], you add them up to get 5. You then do [7 - 2] to get 5. Once you multiply 5x5, you get 25. Hope this helps! :)

Answer:

[4 + 1] *[7-2] =25

Step-by-step explanation:

[4 + 1] *[7-2] =25

We need to get to 25

What makes 25

5*5

4+1 =5

7-2 =5

5*5 =25

So we need brackets around 4+1 and around 7-2

If f(x) is an exponential function where f(4) =17 and f (12.5) = 31, then find the value of f(18.5), to the nearest hundredth.

Svetradugi [14.3K]

Solution: f(18.5)=31.47

Step by step solution:
I started by making an equation in slope intercept form- I found the slope, 28/17, with the points (4, 17) and (12.5, 31). Then I found the y intercept, 1, with the point (4, 17). So the equation is y=28/17x+1. Then I just plugged 18.5 where the x is and solved for y

28/17(18.5)+1=y
28/17(37/2)+1=y
1036/34+1= y
30.47+1=y
y=31.47

Keep in mind that 1036/34 is not exactly 30.47 but that 30.47 was rounded to the nearest hundredth

Hope this helps :)

What is the answer and work to this problem. 4x+2y=14 2x+y=7

Nimfa-mama [501]

The given system of equation has no solution.

Step-by-step explanation:

step 1 :

The given equations are 4x + 2y = 14 and 2x + y = 7.

step 2 :

Let 4x + 2y = 14 be the first equation.

Let 2x + y = 7 be the second equation.

The solution (x,y) can be determined by solving the two equations, if only the given two equations are different.

step 3 :

In first equation taking 2 out as a common factor on both sides, the equation becomes:

2 (2x + y) = 2 (7)

So, the first equation resembles the second one.

step 4 :

Since both the equations are similar, they cannot be solved to get a solution. Therefore, the system of equation has no solution which is also known as inconsistent.
