Answer:

The solution is 4.

Step-by-step explanation:

Given expression is,

2.6a+18.4=28.8

Subtracting 18.4 on both sides,

2.6a+18.4-18.4=28.8-18.4

2.6a=10.4

Dividing 2.6 on both sides,

a=\frac{10.4}{2.6}=4

Since for a = 4,

2.6a+18.4=28.8 is satisfied.

Hence, the solution of the given expression is 4.

How are the graphs of y = | x + 2 | and y = | x | + 2 the same? How are they different?
ruslelena [56]

Answer:

y = | x + 2 |  graph is going to the left and y = | x | + 2 is going up

Step-by-step explanation:

They are the same because both will have the same shape. However, they differ because y = |x| + 2 will shift two places up and y = | x + 2 | will shift two places to the left

Solve the equation. –x + 8 + 3x = x – 6
saul85 [17]
First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.

Then, since it is a positive number, subtract it from that side and the other side.

On the other side, the x becomes -x.

Add the 6 from the other side to the 8 to make 14.

14 = -x

Divide both sides by -1, to get the answer.

x = -14

The formula V=IR shows the relationship between voltage, current, and resistance. Solve this formula for R
netineya [11]

Answer:

The formula  is R =\frac {V}{I}

Step-by-step explanation:

The formula V = I R shows the relationship between voltage, current, and resistance.

It is given by the Ohm's law.

According to this law, at constant temperature, the current flows in any conductor is directly proportional to the potential difference applied.

V = I R

where, V is the potential difference, I is the current and R is the resistance.

The resistance is given by

R = \frac{V}{I}
