the axis of symmetry of a quadratic equation is x = –3. if one of the zeroes of the equation is 4, what is the other zero?
FinnZ [79.3K]
ANSWER

The other zero is

x =  - 10

EXPLANATION

The axis of symmetry serves as the midpoint of the two zeroes.


We were given that the axis of symmetry of the quadratic equation is
x =  - 3


We were also given that, one of the zeroes of the quadratic equation is
x = 4


Let the other zero of the quadratic equation be
x = p

,then, we apply the midpoint formula to find the value of
p

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,




\frac{x_1 + x_2}{2}  = axis \: of \: symmetry

We substitute to obtain,

\frac{p + 4}{2}  =  - 3



We multiply through by 2 to get,

p + 4 =  - 6



This implies that,

p =  - 6 - 4

p =  - 10

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Helen [10]

Answer:

y=7x+1

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

In this problem we have

m=7

point(1,8)

substitute and solve for b

8=7(1)+b

8=7+b

b=8-7=1

The equation of the line is equal to

y=7x+1

Write in descending order.420t + 201 to the 3rd power -210t to the 2nd power
nexus9112 [7]

To answer this, we need to see the polynomial. Descending order is in a way that the first term of the polynomial will be three, the second (in descending order, two....and so on).

420t+20t3-210t2

In descending order is:

20t^3 - 210t^2 + 420t

So, the option is number two.
