Answer:
1/-21
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

x+
−1
12
=6x
Step 2: Subtract 6x from both sides.

=0
Step 3: Add 1/12 to both sides.

I don’t wanna give the exact answer, i want to help you and lead you in the right place so you know the concept and process if a similar question is on an assessment. basically, the set of equations is set up for substitution method. we can agree that y equals 3x-3. so in the second equation, instead of writing “2y” you would SUBSTITUTE the y for 3x-3. so the equation would be 2(3x-3)-x=4. do the distributive property. once you get the equation after doing the distributive property, you solve for x using your algebra skills from previous units (cancel out x’s, for instance). your answer is your x coordinate. in order to find your y, you substitute whatever number you got for x and plug it in to one of the equations, doesn’t matter which. you will then solve for Y using your algebra skills you learned from previous units. after solving, you should get what y=. now you put the number in coordinate pair form which is (x,y)

Answer:
F
Step-by-step explanation:
If the circle is tangent to the x-axis at 4, the center lies on the line x=4.
If the circle is tangent to the y-axis at 4, the center lies on the line y=4.
If the center of the circle is (x, y) = (4, 4) and it is tangent to the axes, then the radius is 4.
The standard-form equation of the circle centered at (h, k) with radius r is ...
(x -h)² +(y -k)² = r²
For the values (h, k) = (4, 4) and r = 4, the equation is ...
(x -4)² +(y -4)² = 16 . . . . . . matches choice F
Answer:
How much is the discount?
=$70
What is the final sale price?=$210
Step-by-step explanation:
$280 =100%
$x =25%
$280 x 25%=7000/100=<u>70</u>
<u>280-70=210</u>
