Answer:

The zeros are the points where the parabola intercepts the x-axis.

\sf x = 7 \implies x - 7 = 0

\sf x = 1 \implies x - 1 = 0

\sf \implies y = a(x - 7)(x - 1)  where a is some constant

If the parabola passes through point (3, 4) then:

\sf \implies a(3 - 7)(3 - 1) = 4

\sf \implies a(-4)(2) = 4

\sf \implies -8a = 4

\sf \implies a = -\dfrac12

So the equation of the parabola is:

\sf y = -\dfrac12(x - 7)(x - 1)

Or in standard form:

\sf y = -\dfrac12x^2+4x-\dfrac72

(3) The difference between two numbers is 8. If the larger is
Alecsey [184]

Answer:

x= 62

y= 54

Step-by-step explanation:

Step one:

given data

let the numbers be x and y and the larger be x the smaller be y

The difference between two numbers is 8

x-y= 8-----------1

If the larger is  subtracted from three times the smaller, the difference is 100

3y-x=100------------2

from eqn 1, x= 8+y

put this in eqn 2

3y-(8+y)=100

3y-8-y=100

collect liker terms

3y-y-8=100

2y=108

y= 54

put y= 54 in eqn 1

x-y=8

x-54= 8

x= 8+54

x=62
