Use point (-3,2):

2 = 4*(-3) + b

b = 2 +12

b = 14

The equation is y = 4x + 14

-x^2+4x-8 <br>axis of symmerty​
V125BC [204]

Answer:

\boxed {\boxed {\sf x=2}}

Step-by-step explanation:

The axis of symmetry can be calculated using the formula:

x=\frac{-b}{2a}

First we must determine a and b from the quadratic: -x^2+4x-8. This is in standard form, with the highest power first in descending order.

Standard form is also: ax^2+bx+c

If we compare this to the quadratic given, we can conclude that:

a= -1 \\b= 4 \\c= -8

Substitute the values for a and b into the formula.

x= \frac{-(4)}{2(-1)}

Multiply in the denominator.

x=\frac {-4}{-2}

Divide.

x=2

This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.

Can anyone explain how you graph things for example, like y=x-4 how would you graph that
Savatey [412]

Answer:

In basicallity if a question such as this pops up, the correct way to go would first be to graph this. y=x-4 would be equivalent to x=4.

My paper work is below:

y = x - 4

0 = x - 4

-x = -4

x = 4

Hope this helped..

Can 18 feet and 5 yards be expressed as a ratio in simplest form
Nuetrik [128]
1 yard is 3 feet.
18/3 = 6
Therefore, the actual ratio is 6 yards to 5 yards. Getting rid of like terms, we find that the simplest form ratio is 6:5
