Answer:
y = 3x - 5

Explanation:
The equation of the line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept

We are given that the slope is 3. Therefore, the equation now is:
y = 3x + c

Now, we need to get the value of c. To do so, we will substitute with the given point (5,10) in the equation and solve for c as follows:
y = 3x + c
10 = 3(5) + c
10 = 15 + c
c = 10 - 15
c = -5

Based on the above, the equation of the line is:
y = 3x - 5

Hope this helps :)

It's easiest to start with the point-slope form of an equation, y-y_1=m(x-x_1), where m is the slope and (x_1, y_1) is the point given.

We have m = 3, x_1 = 5, and y_1 = 10.

We plug in these values to get
y-10=3(x-5).

We now rearrange to get this into slope-intercept form, y=mx+b, by solving for y.

y=3(x-5)+10\\y=3x-15

(4x3+2x+6)+(2x3-x2+2)

Final result :

6x3 - x2 + 2x + 8
Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2". 2 more similar replacement(s).

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(((4•(x3))+2x)+6)+((2x3-x2)+2)
Step 2 :

Equation at the end of step 2 :

((22x3 + 2x) + 6) + (2x3 - x2 + 2)
Step 3 :

Checking for a perfect cube :

3.1 6x3-x2+2x+8 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 6x3-x2+2x+8

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 2x+8
Group 2: 6x3-x2

Pull out from each group separately :

Group 1: (x+4) • (2)
Group 2: (6x-1) • (x2)

What should be added to both sides of this equation to solve for the variable? r + (-12) = 19
Slav-nsk [51]

Answer:

12

Step-by-step explanation:

Then the -12 and +12 will cancel out, so you're left with a clean isolated r on the left:

r -12 +12 = 19 + 12

r = 31
