Solve the following equation using distributive property

Mathematics
1 answer:

Hi there!

Here is the step by step solving :

-19 = 5(x + 9)

Distribute the 5 to the entire parentheses

5 × x = 5x

5 × 9 = 45


-19 = 5x + 45

Subtract 45 from each side of the equation


-64 = 5x

Divide each side of the equation by 5


-64/5 = x


So your answer is : A. x = -64/5


There you go! I really hope this helped, if there's aything just let me know! :)

2x+3y=5,x+y=1 using graphical method in simultaneous equation​
kifflom [539]

Answer:

(-2,3)

Step-by-step explanation:

I used Desmos to input these 2 equations and then locate the point(s) at which they intersect.  Since these are both linear, there will be either 1 solution or none at all, but in this case, there is one solution, and it is at the point (-2,3) which is where the 2 graphs intersect.

What is the distance between the points (6,-7) and (1,5)
amid [387]

Answer: The distance is d = 13 .

Step-by-step explanation:

In order to find the distance between the two points, you need the distance formula:

d = \sqrt{(x_{2} - x_{1})^2 +(y_{2} - y_{1})^2} where there is (x_{1}, y_{1}) and (x_{2}, y_{2}) .

-Use the those two points (6,-7) and (1,5) for this formula:

d = \sqrt{(1 -6)^2 +(5 + 7)^2}

-Then, you start solving:

d = \sqrt{(1 -6)^2 +(5 + 7)^2}

d = \sqrt{(-5)^2 +(12)^2}

d = \sqrt{25 +144}

d = \sqrt{169}

d = 13

So, therefore, the result is d = 13 .

Wich graph matches the equation y+3=2(x+3)
never [62]

Answer:

The leftmost graph [with the points (-3,-3) and (0,3)]

Step-by-step explanation:

y+3=2(x+3)

y+3=2x+6

y=2x+3

The y-intercept is 3, meaning that the line passes through the point (0,3), and it's slope is 2, so it travels 2 units up and 1 unit over. Thus the correct graph is the top left graph, with the two points (-3,-3) and (0,3).

Hope this helps! (:

A soccer ball is kicked and travels 25 meters to the north in 2.5 seconds. At what velocity is the ball traveling?
algol [13]
It would be 10m.
If you divide 25 by 2.5 you get 10, and since we’re using velocity, that’s what we would do.
