What is the final answer for 6x-6-7x=-13/2

Mathematics
1 answer:
olya-2409 [2.1K]3 years ago
6 0
6x - 6 - 7x = -13/2

Multiply both sides by 2:
12x - 12 - 14x = -13

Simplify:
-2x - 12 = -13

Add 12 to both sides:
-2x = -1

Divide both sides by 2:
-x = -1

Change to a positive value of x:
x = 1

I really don’t get this , it’s graphing linear inequalities
ElenaW [278]

The first step in graphing a linear inequality is to graph the linear equality. The equation -x + 4y = -8 is equivalent to 4y = x - 8, which is equivalent to y = \frac{1}{4}x - 2. This is the equation for the line in slope-intercept form, so the line will have a slope of 1/4 and a y-intercept of -2 (see the first image). Notice that the line is solid, rather than dotted. This represents that points on the line are included in the solution, because the inequality sign is ≥, which is not a strict equality (< or >).

Next, we need to figure out which side to shade. To do so, simply pick any point (I like to use the point (0,0) because it makes the calculations easy) and see whether it satisfies the inequality. If it does, shade the side with that point, and if not, shade the opposite side of the graph.

Here we see that the point (0,0) does satisfy the inequality, since -(0) + 4(0) is 0, and 0 ≥ -8, so the top half of the graph should be shaded (see the second image).

What’s the answer for this question
Zinaida [17]

Answer:

It's app. 50.24

Step-by-step explanation:

The area of a circle is A = pi * r ^2

So the area is

= pi * 16

in the question it says to use 3.14 for pi instead

so multiply 16 * 3.14 = 50.24
