Solve the following problem using the elimination method:
-3x + 7y = 12
x - 2y = -3

Answers

Answer:

(3, 3)

Step-by-step explanation:

do you need to show your work or just the answer?

-3x+7y=12 mulitply both sides by 3 of the bottom.

x-2y=-3

-3x+7y=12

3x-6y=-9 < which turns into this

Then you have to sum the equations (vertically) to eliminate one variable.

y=3

Then substitute the given value of "y" into the equation

x-2 * 3=-3 then solve the equation for x (x=3)

y=3 x=3 (3, 3)

*Check your answers.

-3*3+7*3=12

3-2*3=-3

12=12

-3=-3

How to find angles when parallel lines are cut by a transversal?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate exterior angle, alternate interior angles, linear angles, vertically opposite angles, same side interior angles etc.

According to the diagram the parallel lines are cut by the transversal and formed the angles.

Hence, the angles are alternate exterior angles.

Alternate exterior angles are congruent. Hence, the angles are as follows:

10x - 20 = 7x + 4

10x - 7x = 4 + 20

3x = 24

x = 24 / 3

x = 8

Therefore, the angles are as follows:

10x - 20 = 10(8) - 20 = 80 - 20 = 60 degrees

7x + 4 = 7(8) + 4 = 56 + 4 = 60 degrees.

What is the coefficient of XY in the expression *?

Answers

The numerical coefficient of xy in the given expression -7xy is -7.

The numerical coefficient of an expression is a number that is multiplied by a variable or a product of variables. The coefficient is the number that appears in front of a variable or a product of variables. In the case of a constant term, the coefficient is the constant itself.

For example, in the expression 3[tex]x^2[/tex] + 4x - 5, the numerical coefficient of [tex]x^2[/tex] is 3, the numerical coefficient of x is 4, and the numerical coefficient of the constant term -5 is -5.

a). 5 divided by 3/10
b.) 5 divided by 9/10

Answers

Answer:

a) 5 divided by 3/10

To solve this problem, we need to perform the division first, followed by the division. Dividing 5 by 3/10, we have:

5 / (3/10) = (5*10)/3 = 50/3

Simplifying, we have:

50/3 = 16 2/3

Therefore, the result of 5 divided by 3/10 is 16 2/3.

b) 5 divided by 9/10

To solve this problem, we need to perform the division first, followed by the division. Dividing 5 by 9/10, we have:

5 / (9/10) = (5*10)/9 = 50/9

Simplifying, we have:

50/9 = 5 5/9

Therefore, the result of 5 divided by 9/10 is 5 5/9.
