(3,10) and (6,13)Put in slope-intercept form
spayn [35]

ANSWER

y = x + 7

EXPLANATION

We want to use the two points to form a linear equation in slope-intercept form.

That is in the form:

y = mx + c

To do this, we first find the slope by using formula:

m\text{ = }\frac{y_2-y_1}{x_2-x_1}

where (x1, y1) = (3, 10)

(x2, y2) = (6, 13)

So, we have that:

\begin{gathered} m\text{ = }\frac{13\text{ - 10}}{6\text{ - 3}} \\ m\text{ = }\frac{3}{3} \\ m\text{ = 1} \end{gathered}

The slope, m, is 1.

Now, we use the point-slope formula to find the equation. That is:

\begin{gathered} y-y_1=m(x-x_1) \\ \Rightarrow\text{ y - 10 = 1(x - 3)} \\ y\text{ - 10 = x - 3} \\ =>\text{ y = x - 3 + 10} \\ y\text{ = x + 7} \end{gathered}

That is the answer.

Help with #2 it has to do with number 1 that is the polygon you need to find the area of it.
Katena32 [7]
Okay, it's the equation to how find area any other way. A=L×W

This means *picture above*

So then you count over each line meaning 1.
This means L=9 and a 1/2. Since its in between the 2 an 3 on the x-axis.
Now for W or width. It equals 3 since you can count 2 lines and one either ends of the polygon is 1/2 each this creates one when added together.

All you do from there is multiply 9 and 3. This should give you A=area.

Solve the system of equation below x+y+z=2 x-y+5z=6
mamaluj [8]
X + y + z = 2
x - y + 5z = 6

cancelando +y com -y:

x + z = 2*(-5)
x + 5z = 6

-5x -5z = -10
...x +5z = 6
---------------------
-4x = -4 *(-1)
4x = 4
x = 4/4
x = 1

x + z = 2
1 + z = 2
z = 2 - 1
z = 1

x + y + z = 2
1 + y + 1 = 2
2 + y = 2
y = 2 - 2
y = 0 

S: {x, y, z} = {1, 0, 1}

aleksley [76]
This question means the than (8 + 10) x 2 = red markers. She has 32 red markers, 8 blue markers, and 10 green markers. If you add them all up, you get 50 markers.

Find The Value Of x ?
slega [8]

<u>Answer</u>:

1) x  = -1  ||     2) x = 10

<u>Explanation</u>:

1)

→ \log _3\left(\frac{1}{3}\right)=x

→ \frac{1}{3}  = 3^x

→ 3^{-1} = 3^x

→ x  = -1

2)

→ \log _3\left(x-1\right)=2

→ x - 1 = 3^2

→ x -1 = 9

→ x = 9 +1

→ x = 10
