Y = x2 + 4x – 117 i need to know the roots and vertex

Mathematics
1 answer:
velikii [3]3 years ago
4 0

Answer:

Vertex : (-2,-121)

Roots : x=9,-13

Step-by-step explanation: Rewrite the vertex form and use this form to fine the vertex (h,k).

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with zero and solve for x.

I hope this helps you out.

GaryK [48]

Answer:

-9/20

Step-by-step explanation:

For the first two terms, all you have to do is multiply the numerators and the denominators, and cancel out the negative, but because there is a -1 after that, the negative sign comes back, although the -1 doesn't really change the number.

The lines are parallel.

In order to figure this out, let's start off by simplifying both equations as much as we can:
2y = 16 + 4x
Divide by 2
y = 2x + 8

Remember that the slope of that equation is '2' since 'm' in the equation y = mx + b represents slope.

Simplify the next equation:
6y - 30 = 12 x
6y = 12x + 30
Divide by 6:
y = 2x + 5

As you can tell, this line also has a slope of 2.
Parallel lines is defined as two lines that have the same slope. Knowing this, we can infer that these two lines are parallel.

As part of a new fitness plan, Sabir walks on a treadmill at the same speed for 15 minuets every morning. The table shows the ca
Reil [10]
The relationship between Sabir and calories he burns can be modeled using a linear function given by:
y=ax+b
where
a=slope
b=y-intercept
from the graph, the slope will be given as follows:
taking points (3,15) and (12,60)
a=(60-15)/(12-3)=5 calories/minute
thus using the slope and a point (3,15) the equation will be:
a(x1-x)=(y1-y)
plugging the values we obtain:
5(x-3)=y-15
5x-15=y-15
thus
y=5x
thus the equation is:
y=5x

Which set of ordered pairs could be generated by an exponential function?
olasank [31]

Answer:

The correct option is  (1,2), (0, 1), (1, 2), (2, 4).

Step-by-step explanation:

Consider the provided ordered pairs.

The exponential function is in the form of f(x)=ab^x

Where,  a is the initial amount a\neq 0 and  b is the rate of change b>0, b\neq 1

The graph of each exponential function passes through the point (0, a),

f(0)=a\cdot b^0 = a and a\neq 0  

Therefore, Option 1 and 2 and 4 are false.

Hence, the correct option is  (1,2), (0, 1), (1, 2), (2, 4).
