Im confused on #6...help anyone?

Mathematics
1 answer:
nikdorinn [45]3 years ago
6 0

Answer:

Step-by-step explanation:

Using elimination means you either add the two equations together or subtract them. You can first multiply the second equation by 2, so you get 4x - 6y = 24. Then you add the two equations together to get 9x = 42. Then you solve for x and then you can solve for y.

Step by step how to factor:<br> 2y^2+9y+9=0
weeeeeb [17]
Use ac method
for ax²+bx+c=0 when a≠1


multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b


2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that

2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero

y+3=0
y=-3

2y+3=0
2y=-3
y=-3/2


y=-3 and -3/2
it's factored form is (x+3)(2x+3)

Graph the set. in number line<br> (1, ∞) ∩ (−10, ∞)
svlad2 [7]

See attachment for the graph of the set (1, ∞) ∩ (−10, ∞)

<h3>How to graph the set on a number line?</h3>

The set is given as:

(1, ∞) ∩ (−10, ∞)

The above means that the numbers inclusive in the set are numbers between the following set:

  • (1, ∞): All real numbers greater than 1
  • (−10, ∞): All real numbers greater than -10

The intersection of the above set is (1, ∞)

This means that the set (1, ∞) ∩ (−10, ∞) is a set of all real numbers greater than 1

Having done the above illustration, next we plot the set on a number line

See attachment for the graph of the set (1, ∞) ∩ (−10, ∞)
