What numbers add up to -5 and multiply to get -90
Molodets [167]
Let
x-------> the first number
y-------> the second number

we know that

x+y=-5 \\ x=-5-y equation 1

x*y=-90 equation 2

substitute the equation 1 in equation 2

[-5-y]*y=-90 \\ -5y- y^{2} =-90 \\ y^{2} +5y-90=0

using a graphical tool to resolve the second order equation
see the attached figure
the numbers are

The points (3, 24) and (7, 56) represent points of a function where y, the number of photographs, varies directly with x, the nu
tester [92]
(3,24)(7,56)
slope = (56 - 24) / (7 - 3) = 32/4 = 8

y = mx + b
slope(m) = 8
(3,24)...x = 3 and y = 24
now we sub
24 = 8(3) + b
24 = 24 + b
24 - 24 = b
0 = b

so ur equation is : y = 8x + 0...or just y = 8x

to find ur answer, take ur answer choices and sub them into y = 8x and whichever one is true is ur answer.
