Solve by elimination <br> 3x+2y=19<br> -9x+8y=-29
Alja [10]

Step-by-step explanation:

(3x + 2y =19)(3)

-9x + 8y =-29

9x + 6y = 57 <em><u>NOTE</u></em><em><u>:</u></em> we cross here 9x in first

-9x + 8y = -29 we cross here - 9x in second

Since 9x and - 9x are opposite

___________

6y +8y = 57 - 29

14y = 28

Y=28/14

Y=2

Replace y in second equation of this system:

-9x + 8y = - 29

-9x +8(2)= - 29

-9x + 16 = - 29

-9x = -29 - 16

-9x = - 45

X= -45/-9

X=5

Hope this helps..

Point j (-8 -12) is reflected over the x axis where is j
stiv31 [10]

Answer:

J(0,2)

Step-by-step explanation:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Which expression is equivalent to 1/2x+(−7)−2 1/4x−(−2
Lynna [10]

The equivalent expression to the given expression is \mathbf{=-(\dfrac{7}{4}x+5)}

<h3>What is an algebraic expression?</h3>

Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).

From the given expression, we are to determine an expression that is equivalent to:

=\dfrac{1}{2}x + (-7) -2 \dfrac{1}{4}x -(-2)

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.

By doing so, we have:

=\dfrac{1}{2}x -7 -\dfrac{9}{4}x +2

=\dfrac{1}{2}x -\dfrac{9}{4}x +2 -7

=\dfrac{1}{2}x -\dfrac{9}{4}x -5

=-\dfrac{7}{4}x-5

\mathbf{=-(\dfrac{7}{4}x+5)}
