To equations are equivalent if and only if they have the same solution set.
Solve for both of the equations.
-2x = 10
x = -5 <-- Divide both sides by -2
-5x = 25
x = -5 <-- Divide both sides by -5
Both have the solution -5.
So, yes both are equivalent.
Answer:
B. 80 cm^2
Step-by-step explanation:
A = bh/2
A = (FE)(16 cm)/2
A = (10 cm)(16 cm)/2
A = 80 cm^2
Answer:
A
Step-by-step explanation:
given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the given condition x = 24 and y = 360
k = 
= 
= 15
Hence y = 15x is the equation → A
12:3 3/10 :5.5 is the answer
The answer is D because side 3 is to far from side 1 and side 2 because you cant make a triangle out of those measurements
Here's a tip
if the sum of side 1 and side 2 are greater than side 3 then it forms a triangle
