Answer:

39 and 14

Step-by-step explanation:

A + B = 53

A - B = 25

(Add the two equations together)

2A = 78

A = 78/2 = 39

B = 53 - 39 = 14

In what form can a linear equation in x and y be written in?
Sati [7]

Answer:

Slope-Intercept Form of a Line (y = mx + b)

Step-by-step explanation:

The slope-intercept is the most “popular” form of a straight line. Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.

Someone can help me with this please​

Answer:

x = -1 and x = 7

Step-by-step explanation:

2x^2 + 2x - 14x - 14

2x^2 - 12x -14

Divide through by 2 to simplify the expression

x^2 - 6x - 7

x^2 - 6x -7

Now, let's think of two numbers that when added up gives -6 and when multiplied gives -7

Yes! It's -7 and +1

-7 + 1 = -6 , and -7* 1 = -7

Now, lets substitute these numbers in the expression

x^2 -7x + x - 7

factorize

x(x - 7) + 1(x - 7)

(x + 1) (x - 7)

Now equate to zero

(x + 1) (x - 7) = 0

x + 1 = 0

subtract 1 from both sides

x +1 - 1 = 0 -1

x = -1

Also,

x - 7 = 0

Add 7 to both sides

x -7 + 7 = 0 + 7

x = 7

Hence, x = -1 and x =7

Use a form of the distributive property to rewrite the given algebraic expression without parentheses. 2(3x-3)
guajiro [1.7K]

Answer:

6x-6

Step-by-step explanation:

The Distributive property says that a(b+c) = ab+ac

In my example you distribute the value on the outside to the things on the inside

In your problem you have a two on the outside that needs to be distributed to a 3x and a -3

1) 2 multiplied by 3x equals 6x giving you the first part of your answer!

2) 2 multiplied by -3 equals -6 giving you the second part of your answer!

Don't forget that there is a - sign between the 3x and 3, don't drop it!

Put the two values together to get 6x-6

Let me know if you have any further questions :)
