Answer:

a=5/3

Step-by-step explanation:

y=a*x

y+5=a*(x+3)

so 5=3a

a=5/3

The three terms are not like terms, so they cannot be added together.
The expression is simplified.
If you need to factor the expression, then the instructions should be factor the expression, not simplify.

What is the standard form equation of an ellipse that has vertices (18,1) and (−10,1) and co-vertices (4,14) and (4,−12)?
viktelen [127]

Answer: \frac{(x-4)^2}{196} +\frac{(y-1)^1}{169} =1

Step-by-step explanation:

You first need to determine if the ellipse is horizontal or vertical, which can be found by the length of the major axis.

The vertices are at (18,1) and (-10,1). The distance is 28 units.  (horiz)

The co-vertices are at (4,14) and (4,-12) The distance 26 units (vert)

The major axis is horizontal, so the standard form of the ellipse is

\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1 where (h,k) are the coordinates of the center.

To find the center, find the midpoint of the major axis (\frac{x1+x2}{2} ,\frac{y1+y2}{2} )

The center is at (4,1)

Since the major axis is 2a, a would be 28 divided by 2=14 squared : 196

The minor axis is 2b, so b would e 26/2=13 squared: 169

Inserting the center and a,b values into the standard form eq:

\frac{(x-4)^2}{196} +\frac{(y-1)^1}{169} =1

hope this helps.

Is 100 in greater,less, or equal to 3 yd 1 ft
jeka57 [31]
3 ft are in 1 yd
36 in are in 1 yd
36x3=108
108+12=120
So 100 is less than 3 yds 1 ft

Hope this helped!

Answer:

The equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}

Step-by-step explanation:

We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)

First we need to find slope and y-intercept of the line.

The slope is given i.e. m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, y-intercept can be found using:

y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

y=mx+b\\y=-4x-17

Now writing in form of Ax + By = C

y=-4x-17\\4x+y=-17

So, the equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}.
