Find the equation of line (use exact numbers)​
maw [93]

Answer:

y=3x+3

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( \frac{rise}{run} ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

y=mx+3

Now find the slope. Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3

The slope is 3. Insert this value:

y=3x+3

3(x - 5) = 30<br> I dont know how to solve this
Anastaziya [24]

Answer:

x=15

Step-by-step explanation:

3(x-5)=30

First, you would distribute the three to the x and the negative five.

3x-15=30

Then you would add 15 to the 15 to cancel it and to the 30 to make it even.

3x-15=30

  +15=+15=

3x=45

Finally, you would divide 3 into both sides, cancelling out the three and fiving you,

x=15

Hope this helped!

The first term of an arithmetic sequence is -2. The eighth term of the sequence is 26. What is the common difference of the arit
andreev551 [17]

Answer:

d = 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₁ = - 2 and a₈ = 26 , then

- 2 + 7d = 26 ( add 2 to both sides (

7d = 28 ( divide both sides by 7 )

d = 4
