The question is asking 15+2*9=? so to do this first multiply 2*9 which = 18 and then add 15, 18+15= 33
Answer:
1. Absolute value
: d. | - 7| = 7
2. All real numbers
: b. 3x = 3x
3. x = -5 : c. 5x = -25
4. No solution
: a. |2x| = -10
5. Adding the opposite to both sides of the equation.
: e. Canceling
Step-by-step explanation:
1. Absolute value
: d. | - 7| = 7
The absolute value is considered the distance to 0... so if there's a negative sign in the value, the negative sign disappears.
2. All real numbers
: b. 3x = 3x
If we divide both sides by 3, we have x = x, which will always be true.
3. x = -5 : c. 5x = -25
If we multiply each side by 5, we have 5(x) = 5(-5) thus 5x = -25
4. No solution
: a. |2x| = -10
The result of an absolute value cannot be a negative number. So, that has no solution since there's no value of x that would make this true.
5. Adding the opposite to both sides of the equation.
: e. Canceling
If you have for example (x = -5) and you add 5 on both sides, you cancel the value on the right side... (becomes x + 5 = 0).
Answer:
B. The company hires 10 employees every year.
Step-by-step explanation:
One way to look at this is to look at the units on the number 10. Working strictly with units, we get ...
f(x) = 10x . . . . . . f(x) is employees, x is years
employees = 10·years
Dividing by years, we find the meaning of "10":
employees/year = 10
The division symbol (/) is read as "per", so this means the number 10 in the equation is the number of employees per year that are hired.
10 employees are hired every year.
The property you use to get from 4(x + 3) to 4x + 12 is the distributive property.
