Answer:

Notice the line in between the 61 degrees and b

Step-by-step explanation:

I can't remember what this kind of angle is called, but when you have a straight line with another line coming out of it like this, then the sum of both angles has to equal 180 so what would you add to 61 to get to 180?

Answer:

b=119

Step-by-step explanation:

For the straight line with 61 degrees and b would be a total of 180 degrees when added.

180-61=b

119=b

Solve 3x + k = cfor x.

Ghella [55]

First, subtract k from both sides. That means c - k is in the left side and 3x is on the right. Then, divide by 3 on both sides. So, the answer is x = (c - k) / 3.

Complete the equation of the line through ( 4 , -8 ) and ( 8 , 5 )

irinina [24]

Answer:

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

Step-by-step explanation:

Given:

Let,

point A( x₁ , y₁) ≡ ( 4 ,-8)

point B( x₂ , y₂) ≡ (8 , 5)

To Find:

Equation of Line AB =?

Solution:

Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula

$(y - y_{1} )=(\frac{y_{2}-y_{1} }{x_{2}-x_{1} })\times(x-x_{1}) \\$

Substituting the given values in a above equation we get

$(y-(-8))=(\frac{5-(8)}{8-4})\times (x-4)\\ \\(y+8)=\frac{13}{4}(x-4)\\\\4(y+8)=13(x-4)\\4y+32=13x-52\\13x-4y=84...............\textrm{which is the required equation of the line AB}$

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

How do u estimate 92×68?<br> Add the finished product <br> Too.

disa [49]

You round 92 to 90. Then you round 68 to 70. Now you know that 9x7 = 63. You add to zeros to that answer and get 6300. So 92x68 is about 6300. The actual answer of the problem 6256 that will round up to 6300
