SUPER URGENT!!!!!!!! I NEED HELP!!!!!1 PLSSSS!!!!!Use the linear combination method to solve the system of equations. Explain ea

Vedmedyk [2.9K]

Answer:

x=-3,y=-2

Step-by-step explanation:

Given 2 expressions

S1: $3x-8y=7$

S2: $x+2y=-7$

Write one equation in terms of any variable (x or y)

Here I am writing S1 in terms of y

$3x-8y=7\\3x-7=8y\\y=\frac{3x-7}{8}$

Substitute this value of y as the value of y in S2

⇒ $x+2y=-7\\x+(\frac{3x-7}{8} )\times2=-7\\8x+6x-14=-56\\14x=-42\\x=-3$

Therefore $x=-3$

Substitute this value of x in any of the expressions S1 or S2

Here i am substituting in S2

⇒ $x+2y=-7\\-3+2y=-7\\2y=(-7+3)\\2y=-4\\y=-2$

Therefore x=-3 and y=-2

If the volume of the cylinder is represented by 5x2 + 15x + 2 and the height is 5x, which expression represents the area of the

Gwar [14]

Given:
V = 5x² + 15x + 2, the volume
h = 5x, the height

Let A = the area of the base.
Because V = Ah, therefore
A*(5x) = 5x² + 15x + 2
$A = \frac{5x^{2}+15x+2}{5x}$

Answer:
$A=x+3+ \frac{2}{5x}$

2b−15>21? How do I do this and what is the answer???

Mashcka [7]

2b - 15 > 21

add 15 to both sides:

2b-15+15 > 21 + 15

2b > 36

Divide both sides by 2 :

2b/2 > 36/2

2b = 36

b = 36 / 2

b > 18

hope this helps!
