What is the x-coordinate of the solution of the following system of equations?

1 answer:

8 0

Plug in the x value from the second equation
3(-y+2)+2y=12
use distributive property.
-3y+6+2y=12
since the y values are in the same side of the = sign, just put them together.
-y+6=12
subtract 6 from 6 and 12.
-y=6
since the equation has a negative y, divide what is left by -1.
y= -6.
that is the y value. now plug that in to the first equation.
3x+2(-6)=12
multiply.
3x-12=12add 12 to both 12s
3x=24
divide.
x=8.

the ordered pair is (8, -6), and the x value is 8.

3^4 × h^5 × g^2 / 3^2 × h^8<br><br> Could you show me the steps so I can understand easier?

hoa [83]

Answer:

$\dfrac{3^{2} \times g^{2}}{h^{3} }$

Step-by-step explanation:

We have to simplify the following mathematical expression.

The expression is $\dfrac{3^{4} \times h^{5} \times g^{2}}{3^{2} \times h^{8} }$

Now, $\dfrac{3^{4} \times h^{5} \times g^{2}}{3^{2} \times h^{8} }$

= $3^{(4 - 2)} \times h^{(5 - 8)} \times g^{2}$

{Since, all the terms are in product form, so, we can treat them separately}

{We know the formula of exponent $\dfrac{x^{a} }{x^{b} } = x^{(a - b)}$ }

= $3^{2} \times h^{- 3} \times g^{2}$

= $\dfrac{3^{2} \times g^{2}}{h^{3} }$ (Answer)

{Since, we know, $x^{- a} = \dfrac{1}{x^{a}}$ }

Sedbober [7]

Answer:the length of line segment AC is 14

Step-by-step explanation:

The diagram is shown in the attached photo

Since Angle A B C and B C A are congruent. It means that they are equal. An isosceles triangle is a triangle that has two equal sides and two equal base angles. Since Angle A B C and B C A are equal, it means that the triangle is an isosceles triangle. It also means that sides AC and AB are equal. The expression becomes

3x - 7 = 2x

3x - 2x = 7

x =7

To determine the length of line segment AC. We will substitute x = 7 into 3x - 7. It becomes

3×7 - 7 = 21 - 7 = 14
