Solve for the following equation <br> 1/2(2 – 4x) + 2x = 13
mart [117]

Answer:

no solution

Step-by-step explanation:

1/2(2-4x)+2x=13

We simplify the equation to the form, which is simple to understand

1/2(2-4x)+2x=13

Simplifying:

+ 0.5*(2-4x)+2x=13

Reorder the terms in parentheses

+(+1-2x)+2x=13

Remove unnecessary parentheses

+1-2x+2x=+13

We move all terms containing x to the left and all other terms to the right.

-2x+2x=+13-1

We simplify left and right side of the equation.

0x=+12

0=12

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

PLEASE HELP! IM A MONTH BEHIND IN MATH AND FREAKING OUT T^T PLZZZZ
ANTONII [103]
A) Let x stand for time, y stand for velocity.
We are given the points (2,50), (6, 54). We can make a line using the slope intercept form
y = mx + b.
slope is (54 - 50)/(6-2)  = 4/4 = 1
y = 1x + b
plug in point (2,50) to find b
50 = 1(2) + b
50-2 = b
48 = b
the equation is  y = 1x + 48
Make standard form.
<span>x - y = -48
</span><span>b) make a table and plot points for the first 7 hours
Table Is attached.
Good Luck!
