The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
loris [4]3 years ago

Answer:

<em>(D). Opens up with vertex at (- 3, - 4) </em>

Step-by-step explanation:

Vertex form of quadratic equation is f(x) = a(x - h)² + k

If a > 0 the parabola is facing up , or down if a < 0 .

<em>(D). Opens up with vertex at (- 3, - 4)</em>

Write the equation of the line that is parallel to y=1/4x+5 and passes through (2,-9)
Tamiku [17]

Answer:

The answer is

<h2>y =  \frac{1}{4} x -  \frac{19}{2}</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y=1/4x+5

Comparing with the general equation above

Slope = 1/4

Since the lines are parallel their slope are also the same

Slope of parallel line = 1/4

So the equation of the line using point

(2,-9) and slope 1/4 is

<h3>y + 9  =  \frac{1}{4} (x - 2) \\ y + 9 =  \frac{1}{4} x -  \frac{1}{2}  \\ y =  \frac{1}{4} x -  \frac{1}{2}  - 9</h3>

We have the final answer as

<h3>y =  \frac{1}{4} x -  \frac{19}{2}</h3>

Hope this helps you

Rectangle with a width of 36 centimeters and a perimeter of 80 centimeters
olga2289 [7]

Answer: Height = 4 centimeters

Area = 144 cm^2

Step-by-step explanation:

So we know that on a rectangle opposite sides are equal in distance.

If one side of the rectangle is 36 centimeters then that means the opposite side is also 36 centimeters.

36 + 36 = 72 centimeters

The perimeter is the sum of all sides, so two out of the four of our sides total to 72 centimeters. So the remaining length of both sides is as follows:

80 - 72 = 8

The sum of the remaining sides is 8 so divide it between the two and that is the height.

8/2 = 4

I'm not sure what the question wants so here is pretty much everything:

Height: 4 cm

Area: 144 cm^2

What would be the slope for (-4,-7) (-6,4)​
Sliva [168]

Answer:\frac{11}{-2}

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

\frac{y2-y1}{x2-x1} = m

so when using that formula with the cords, you get

\frac{4-(-7)}{-6-(-4)}

and then subtract everything and you'll get

\frac{11}{-2}
