2x+3y=-11, and x=2y+12 solve in substition equations

Answers

Answer 1

Answer: The answer would be (2,-5)

Answer 2

Answer: Because you know the equation for what x is, you can substitute (2y+12) for x. Your new equation would look like this;

2(2y+12)+3y=-11

Distribute the 2 into 2y+12

4y+24+3y=-11

Add 4y and 3y

7y+24=-11

Subtract 24 from both sides

7y=-35

y=-5

Now, substitute -5 in for y in the 2nd equation.

x= 2(-5)+12
x=-10+12
x=2

x=-5
y=2

Solve the inequality.

Answers

Answer:

y > 9

Step-by-step explanation:

Given inequality:

$-6 > -(2)/(3)y$

To solve the given inequality, we need to isolate y on one side of the equation.

Begin by multiplying both sides of the inequality by 3 to eliminate the fraction on the right side:

$-6 \cdot 3 > -(2)/(3)y\cdot 3$

$-18 > -2y$

Now, divide both sides of the inequality by -8 to isolate y. Remember to reverse the inequality sign, as we are dividing by a negative number.

$(-18)/(-2) > (-2y)/(-2)$

$9 < y$

Therefore, the solution is:

$\Large\boxed{\boxed{y > 9}}$

Over the 52 weeks in 2000 the price per share of a certain stock ranged in value from a low of $10.69 to a high of 33.54 by how much did the high value differ from the low value?

Answers

33.54 -10.69 = 22.85

correct, the word difference means to subtract so the difference of 33.54 and 10,69 just means 33.54-10.69=22.85

Answer=$22.85
