slega [8]

Answer:

250= 1.50x + 20

Step-by-step explanation:

here 250 is the goal. 1.50 is how much she makes for a cup and x is the number of times to get x much. with how much her parents gave is 20. so we add the money her parents give and 1.50 times x to know the money shegets from all the lemonade selling. graphing the equation but I cant do it on here

How do you factor 2n^2+3n-9

mario62 [17]

Find the factors that multiply to give 2n^2 and -9 but add to give 3n.
2n and n give 2n^2
-3 and 3 give -9
2n*3=6n ... (1)
n*(-3)=-3n ... (2)
(1)+(2)=3n
Group the factors that do not have an effect/interaction to each other from the above.
That is, 2n and -3, and n and 3

2n^2+3n-9=(2n-3)(n+3)

Which of the following equations has the same solutions as the equation 3x+2y=-12? Check all that apply.

grigory [225]

ANSWER

$B,C,E \: and \: F$

EXPLANATION

The given equation is
$3x + 2y = - 12$

The solution to this equation can be found by making y the subject.

$\Rightarrow \: 2y = - 3x - 12$

$\Rightarrow \: y = - \frac{3}{2} x - 6$
This equation has infinitely many solution. Any real value we choose for x, there is a corresponding y-value.

To find which of the given options also has the same solution, we make y the subject.

A

$3x - 2y = 12$

$\Rightarrow \: - 2y = - 3x + 12$

$\Rightarrow \: y = \frac{3}{2} x - 6$

This is not the same as the given equation.

B

$- 3x - 2y = 12$

$\Rightarrow \: - 2y = 3x + 12$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This solution is the same as the one given.

C.
$15x + 10y = - 60$

$\Rightarrow \: 10y = - 15x - 60$

$\Rightarrow \: y = - \frac{15}{10} x - \frac{60}{10}$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This is the same as the above solution.

D.
$6x + 2y = - 12$

$\Rightarrow \: 2y = - 6x - 12$

$\Rightarrow \: y = - 3 x - 6$

This is not the same as the one given.

E.

$6x + 4y = - 24$

$\Rightarrow \: 4y = - 6x - 24$

$\Rightarrow \: y = - \frac{6}{4} x - \frac{24}{4}$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

This is the same as the one given.

F.

$1.5x + y = - 6$

$\Rightarrow \: y = - 1.5x - 6$

$\Rightarrow \: y = - \frac{3}{2} x - 6$

Thus is the same as the one given.

G.
$x + \frac{2}{3} y = - 12$

$\Rightarrow \: \frac{2}{3} y = - x - 12$

$\Rightarrow \: y = - \frac{3}{2} x - 12 \times \frac{3}{2}$

$\Rightarrow \: y = - \frac{3}{2} x - 18$

This is not the same as the one given.
