The line y=x+4 is given in slope-intercept form (y=mx+b) where m is slope and b is the y-intercept.

Parallel lines have the same slope, so we know the line will have a slope of 1. To find the equation of the new line we can plug the slope and given point into the point-slope equation defined as y-k = m(x-h) given point (h,k).

y-5 = 1(x-6)

Now solve the equation for y.

The answer is: y = x - 1

None of the choices are correct.

Answer:

C. Midsegment of a Triangle Theorem

Step-by-step explanation:

After you eliminate the nonsense choices, the answer remains.

A - concurrency of medians requires 2 or more medians. There are no medians in this problem

B - there is no indication the triangle is isosceles

C - the applicable choice (segment DE is a "midsegment", hence parallel to BC)

D - has to do with measures of sides, which are not involved in this problem

Answer:

cos^(-1)(12/13) = 22.62°

Step-by-step explanation:

Inverse trig functions are used to find angles. I was taught SOH CAH TOA: sine = opposite/hypotenuse, cosine = adjacent / hypotenuse, tan = opposite / adjacent.

Here, we have an adjacent side length and the hypotenuse. So we use inverse cosine.

If B is the midpoint of AC and the length of AC is 23.8 what is the legength of AB

swat32

Hey there,

So explain and to illustrate (how $B$ is the midpoint of $AC$ and the length of $AC$ is 23.8 what is the length of $AB$

<span> A-----------------B----------------C
</span>
So, $\boxed{AC}$ in the problem here is to be considered the (Whole area of this line). $AC$ is the whole thing.

So, what we do in this problem, we do . . .

23.8 ÷ 2 because we need to find what is $AB$ , so we will find the one half of it, which in this illustration is to be considered $AB$

23.8 ÷ 2 = $\boxed{11.9}$

$\boxed{AB=11.9}$

Hope this helps.

Answer:

Step-by-step explanation:

Okay, so you need to create an equation which shows that twice the sum of a number (n) and 7 is 3 times that number. So you need twice the sum of n + 7 and that will equal 3 times n.

2(n + 7) = 3n

Now, multiply

2n + 14 = 3n

2n + 14 -2n = 3n - 2n

14 = n

So the number is 14. Now you can check your answer

2(14 + 7) = 3(14)

2x21 = 42

42 = 42
