Answer:

Greater ; Greater

Smaller ; Greater

Step-by-step explanation:

Slopes

First row

A: 15/2

B: (25-12.5)/(4-2) = 12.5/2

A has a greater slope than B

-4x + 2y = 8

2y = 4x + 8

y = 2x + 4

A: 2

B: 3/2

A has a greater slope than B

Second Row

A: (2.6-2)/(3-0) = 0.6/3 = 0.1

B: (5-4)/(4-0) = 1/4 = 0.25

A has a smaller slope than B

A: 60

B: (325-50)/5-0) = 275/5 = 55

A has a greater slope than B

Which equation has the same soultions as x^2+6×-7=0
blagie [28]
x^2+6x-7=0 \\   a=1 \\ b= 6 \\ c=-7 \\ \\  \boxed{\boxed{\Delta=b^2-4ac}} \\ \\ \Delta=6^2-4*1*(-7) \\ \Delta=36-(-28) \\ \Delta=64 \\ \Delta\ \textgreater \ 0 \Rightarrow \text{we have 2 solutions :} X_1 \ and X_2 \\ \\ \boxed{X_1= \frac{-b- \sqrt{\Delta} }{2a} } \Rightarrow X_1= \frac{-6-8}{2}=-7 \\ \\ \boxed{X_2= \frac{-b+ \sqrt{\Delta} }{2a} } \Rightarrow X_2= \frac{-6+8}{2} =1
