What is the solution to the system of equations? you must show all work to recieve full credit!

Use the substitution method:
2x - 6y = -12
x - 2y = -8
Then x = 2y - 8
Substitute in the first equation:
2(2y - 8) - 6y = -12
4y - 16 - 6y = -12
-2y = 4
y = -2
Now substitute y in one of the two equations given you prefer:
For example x-2*(-2) = -8
x + 4 = -8
x = -12
The solutions are x = -12 and y = -2

Can someone help and explain ? thank you !

$\sf Hello!$

$\sf y = 2x^{2} + 4x - 3$

$\sf Discriminant$ :

= $\sf b^{2} - 4ac$

= $\sf (4)^{2} - 4.(2).(-3)$

= $\sf 16 - (-24)$

= $\sf 16 + 24$ = $\sf 40$

$\sf Since,$
$\sf D \:is\:Greater\: than\: 0.$

$\sf Roots\: are\: Real\: and\: Distinct$

$\sf Hence,$

$\sf y = 2x^{2} + 4x - 3\: have\: A.\: Two\: real\: roots$

Evaluate and match each expression.

avanturin [10]

Answer:

12+x=12+4=16

3x+y=3*4+7=12+7=19

4y-10=4*7-10=28-10=18

1/2xy=1/2*4*7=28/2=14

Ben thinks that the slope ratio for this triangle is 7/10. Carlissa thinks the ratio is 10/7 Who is correct? Explain your thinki

Alekssandra [29.7K]

Answer:

Both answers are correct, depending on the angle taken as reference

Step-by-step explanation:

we know that

In a right triangle

The slope ratio of the triangle is equal to the function tangent

The function tangent in a right triangle is equal to the opposite side to the angle divided by the adjacent side to the angle

$tan(35)=\frac{7}{10}$ -----> Ben's ratio

and

$tan(55)=\frac{10}{7}$ ------> Carlissa's ratio

therefore

The slope will depend on the angle taken as a reference

Both answers are correct, depending on the angle taken as reference.
