PLEAS HELPPP Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added together, the x term is eliminated?

One-fifth x + three-fourths y = 9

Two-thirds x minus five-sixths y = 8

a. –10 times the first equation and 3 times the second equation
b. 10 times the first equation and 3 times the second equation
c. –3 times the first equation and 5 times the second equation
d. 3 times the first equation and 5 times the second equation

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

answer: a

step-by-step explanation:

10.2 units

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
