3(5y+2)-y=2(y-3)<br><br>please help. I'm desperate

Keith_Richards [23]

Answer:

y = -1

Step-by-step explanation:

((3 • (5y + 2)) - y) - 2 • (y - 3) = 0

Step 2 :

Equation at the end of step 2 :

(3 • (5y + 2) - y) - 2 • (y - 3) = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

12y + 12 = 12 • (y + 1)

Equation at the end of step 4 :

12 • (y + 1) = 0

Step 5 :

Equations which are never true :

5.1 Solve : 12 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2 Solve : y+1 = 0

Subtract 1 from both sides of the equation :

y = -1

One solution was found :

y = -1

Find the standard equation of the circle defined by the equation x^2 + y^2 +8x - 12y + 43 = 0. ANSWERS ATTACHED, due in 2 HOURS,

puteri [66]

Answer:

Solution: Option C

Step-by-step explanation:

Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).

$x^2\:+\:y^2\:+8x\:-\:12y\:+\:43\:=\:0$ (Factor the expression "x² + 8x")

$x^2+8x = x\left(x+8\right)$ (Factor the expression "y² - 12y")

$\:y^2-12y =y\left(y-12\right)$

That leaves us with the expression $\left(x-\left(-4\right)\right)^2+\left(y-6\right)^2=3^2$ , or in other words $(x+4)^2 +(y-6)^2 = 9$ . As you can see our solution is option c.

The equation represents an ellipse. which point is the center of the ellipse? (−9, 5) (−5, 9) (5, −9) (9, −5)

Igoryamba

The point which is the center of the ellipse whose equation is; (y+5)²/121+(x-9)²/49=1 s in the task content is; (-5, 9).

<h3>Which point represents the center of the ellipse whose equation is given as; (y+5)²/121+(x-9)²/49=1?</h3>

It follows from convention that the equation of an ellipse usually takes the form;

(y-h)²/a²+(x-k)²/b²=1 in which case, the center of the ellipse is given by the point; (h, k).

On this note, By comparison of the actual equation and the standard equation, it follows that;

+5 = -h and consequently, h = -5,

-9 = -k and consequently, k = 9.

Ultimately, the point which is the center of the

ellipse is; (-5, 9).

Remark: The equation of the ellipse which is missing in the task content is; (y+5)²/121+(x-9)²/49=1

Jason deposits $5 into his savings account twice a week for 6 weeks. How much money will he have saved after 6 weeks?

gregori [183]

Answer:

$60

The equation is x(5(2))=s or x(10)=s when x = number of weeks

Step-by-step explanation:

For 6 weeks, all you have to do is plug in the 6 where the <em>x</em> is.

6(5(2)) = s

6(10) = s

60 = s

or

6(10) = s

60 = s
