Answer:

3x means you have three x's. Then 3x - x means you have three x's and you take away (subtract) one x. This would leave you with two x's.

7. Write the equation of a line which passes through the points (-3,5) and (6,23)
faust18 [17]

Answer:

answer to the equation is

y = 2x + 11

Step-by-step explanation:

y = mx + b

first find the slope of the line using the two points

slope \: m =  \frac{y2 - y1}{x2 - x1}  =  \frac{23 - 5}{6 - ( - 3)}   \\ =  \frac{18}{9}  \\ slope \: m = 2

substitute 2 for m and use one of the points for x and y and solve for b

5 = 2( - 3) + b \\ 5 =  - 6 + b \\ 5 + 6 = b \\ b = 11

Now that you found b, the y-intercept, you can substitute that into the equation for your line

y = 2x + 11

Find the values of x and y ​
icang [17]

Answer:

x=15\\y=38

Step-by-step explanation:

By definition, the sum of the interior angles of a triangle is 180 degrees.

You can observe that the  given triangle has an angle that measures 90 degrees and it also has two equal sides.This means that  the other two angles are equal.

Knowing this, you can conclude that the triangle  is an Isosceles Right Triangle and the other angles measure 45 degrees each.

Therefore, now you know that:

3x=45

Solving for "x", you get that its value is:

x=\frac{45}{3}\\\\x=15

And for the other angle:

y+7=45

Solving for "y", you get that its value is the following:

y=45-7\\\\y=38
