The answer is 7n-1.3. Use the distributive property to multiply 7 by n-3.4. Subtract like terms and it's simplified
At the time 4 PM will it be after they each have worked 4 shifts. Option E is correct.
<h3>What exactly is simplification?</h3>
Simplifying means making something easier to do or comprehend, as well as making something less difficult.
Mashud and Iqbal are security guards at a top-secret federal vault. They each work 8-hour shifts, If Mashud begins his shift at 8 PM,
The time will it be after they each have worked 4 shifts;
8 PM + 8 hour =4 AM
4 AM + 8 hour = 12 PM
12 PM+ 8 hour =8 PM
8 PM + 8 hour = 4 PM
Hence, option E is correct.
They will each have worked four shifts by the time it is 8 PM.

Answer:
the third one
Step-by-step explanation:
Answer:

Step-by-step explanation:

This is written in the standard form of a quadratic function:

where:
- ax² → quadratic term
- bx → linear term
- c → constant
You need to convert this to vertex form:

where:
To find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:

Using your original equation, identify the a, b, and c terms:

Insert the known values into the equation:

Simplify. Two negatives make a positive:

X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:

Simplify using PEMDAS:

The value of y is -6 (3,-6). Insert these values into the vertex form:

Insert the value of a and simplify:
