Write an equation of the line in standard form.
Andreyy89

Answer:

Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:

to switch into y=mx+b form do this:

3x-y=5

-y=5-3x

y=-5+3x

y=3x+(-5)

2y-15x=8

2y=8+15x

y=4+7 1/2x

y=7 1/2x+4

THe slope of any line in y=mx+b form is m. Therefore in this equation:

y=3x+(-5)     3 is the slope

The y intercept of any line is the +b:

y=7 1/2x+4 -therefore 4 in this equation is our y intercept.

Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)

since 3 is our slope and 4 is our y intercept the equatuon is :

y=3x+4

NOw all we need to do is move this into standard form:

y=3x+4

-3x+y=4

-3x+y=4 is your final answer

-hope this helped

Answer:

x=111

Step-by-step explanation:

the sum of angles of triangle is 180

find te missing angle in the triangle first :

180-29-82=69

find x now: the measure of straight angle is 180:

x+69=180

x=180-69=111

this one way to find x

another way is that x=82+29=111

Function k is a continuous quadratic function that includes the ordered pairs shown in the table .
I am Lyosha [343]

Complete question is;

Function k is a continuous quadratic function that includes the ordered pairs shown in the table. (-1,5), (0,8); (1,9), (2,8); (3,5) (4,0) Over which interval of the domain is the function Increasing?

A (1, ∞)

B. (-∞,1)

C (-∞, ∞)

D. (-∞,9)​

Answer:

Option B - (-∞ , 1)

Step-by-step explanation:

From the ordered pairs given, we observe the following:

From (-1, 5) to (0, 8);

In this, 8 is more than 5, thus there is an increase.

From (0, 8) to (1, 9);

In this, 9 is more than 8, thus there is an increase.

From (1,9) to (2, 8);

In this, 8 is less than 9, thus there is a decrease.

Looking at all the ordered pairs, we can see that f(0) = 8 and f(2) = 8.

Thus, we can say that; f(0) = f(2)

This means that our maximum value is likely in the middle of 0 and 2.

Now, from all the ordered pairs, f(1) = 9 is the maximum value of the function.

It now means that when x = 1, the direction of the function changes.

We have seen that at points before x = 1 the function was increasing but after that point the function will begin decrease.

Thus, we can conclude that in all the values that fall in the range of x < 1, the quadratic function will be increasing.

So, the correct answer among the given options is: (-∞ , 1)
