Slope is rise over run. So you "rise" 6 spaces from -1 to 5 and then you "run" 5 spaces to the right i believe it will be 6/5.

b²=225
b=15
Answer:
If alex took the same route walking 4.5 km/h at a rate of 3.6 km/h it would take him 0.9 hours
5x+10y=1750
x+y=100
Multiply the second equation by -5 and add
5y=1250, so y=250
Plugging that back in, we get that x=-150, but that doesn't make sense, so it's either that they sold negative short sleeved shirts or didn't reach their goal of 1750 dollars
Answer:
m∠CEA = 90°
∠CEF is a straight angle
∠AEF is a right angle
Step-by-step explanation:
we know that
BE bisects ∠CEA -----> given problem
so
m∠CEB=m∠BEA
m∠CEA=m∠CEB+m∠BEA
The measure of angle CEA is a right angle -----> m∠CEA=90°
The measure of angle CEF is a straight angle -----> m∠CEF=180°
m∠CEF=m∠CEA+m∠AEF
The measure of angle AEF is a right angle -----> m∠AEF=90°
therefore
The statements that must be true are
m∠CEA = 90°
∠CEF is a straight angle.
∠AEF is a right angle
