HELP asap plz Solve 2y^2 – 3y = 2

Mathematics

Veseljchak [2.6K]3 years ago

Your answer is y = -1/2 and y = 2

To solve this quadratic we first need to subtract 2 from both sides to set it equal to 0, which gives us 2y² - 3y - 2 = 0

Then we just need to factorise it:

2y² - 3y - 2 = 0
(2y + 1)(y - 2) = 0

Now we can set each bracket equal to 0 and solve for y:
2y + 1 = 0
2y = -1
y = -1/2

y - 2 = 0
y = 2

I hope this helps! Let me know if you have any questions :)

Write the equation of the ellipse graphed below.
Lana71 [14]

Answer:

Step-by-step explanation:

This is a horizontally stretched ellipse.  That means that the horizontal line which is represented by the x-axis is the longer one.  The equation for this type of ellipse is

\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1

In an ellipse, the a value is ALWAYS bigger than the b value, and since the x-axis represents the longer axis, the a goes under the x-squared term.  

To solve for the h, the k, the a, and the b, we simply have to do some counting.  The center of the ellipse, the (h, k) our of equation, is sitting at (4, 6).  Put them where they belong in the equation.  The a axis (the horizontal one) is 8 units long, and the b axis (the vertical one) is 4 units long.  Square both of them and put them where they belong in the equation:

\frac{(x-4)^2}{64}+\frac{(y-6)^2}{16}  =1

There you go!

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve
AfilCa [17]

Answer:

The original length of each side of the equilateral triangle = x =15 inches

Step-by-step explanation:

Let Original length of side of equilateral triangle = x

If it is increased by 5 inches, the length will become = x+5

Since in equilateral triangle all the ides have same length so,

New Length of side 1 = x+5

New of side 2 = x+5

New Length of side 3 = x+5

Perimeter of triangle = 60 inches

We need to find the value of x

The formula used is: Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3

Putting values in formula and finding x

Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3\\60=x+5+x+5+x+5\\60=3x+15\\60-15=3x\\45=3x\\x=\frac{45}{3}\\x=15

So, the original length of each side of the equilateral triangle = x =15 inches

What is the value of f(-16) if f(x)= 2x-16?
Elza [17]
F (x) = f (-16)
So you should plug -16 in for x 

f (-16) = 2(-16) -16

f(x) = -32 -16

f(x) = -48
