Answer:

x = 0

Step-by-step explanation:

AB + BC = AC

therefore

2x+8 + 2x+ 12 = 20

combine like terms

4x+ 20 = 20

Subtraction property of equality

4x + 20 - 20 = 20 - 20

4x = 0

Division property of equality

4x/4 = 0/4

x=0

What's the difference between ACT and SAT and when do I take one or the other?
Ilia_Sergeevich [38]
The SAT and ACT <span>generally test the same types of content. Both test scores are used for college admissions and merit-based scholarships. The biggest differences between the tests are that the ACT has a Science Test, and there’s one SAT Math Section for which you cannot use a calculator. 
</span>
The best way to decide if the SAT or ACT is right for you is to take a timed full-length practice test <span>in each. Since the content and style of the SAT and ACT are very similar, factors like how you handle time pressure and what types of questions you find most challenging can help you determine which test is a better fit. For example, the pace of the SAT gives you a tad more time to think through problems, while the ACT can be more of a time crunch. Some students really thrive under the pressure of the clock, while others prefer the extra time to ponder a question.</span>

X= 7 4. Find the equation of a line passing through (5, -6) perpendicular (b) 3x + 5y = (d) 7x - 12y (f) x = 7 (a) 2x + y = 12 (
goldfiish [28.3K]

Given data:

The first set of equations are x+y=4, and x=6.

The second set of equations are 3x-y=12 and y=-6.

The point of intersection of first set of te equations is,

6+y=4

y=-2

The first point is (6, -2).

The point of intersection of second set of te equations is,

3x-(-6)=12

3x+6=12

3x=6

x=2

The second point is (2, -6).

The equation of the line passing through (6, -2) and (2, -6) is,

\begin{gathered} y-(-2)=\frac{-6-(-2)}{2-6}(x-6) \\ y+2=\frac{-6+2}{-4}(x-6) \\ y+2=x-6 \\ y=x-8 \end{gathered}

Thus, the required equation of the line is y=x-8.
