Hi, I'm an employer of Brainly. Someone will answer you in the next 10 minutes. Thank you for your patience! Have a great day.
Answer:
B
Step-by-step explanation:
A) x + 4y = -15
B) -2x -8y = 30
Multiplying A) by 2
A) 2x + 8y = -30
This has NO solution because A) and B) are actually the same equation.
Equation B = Equation A times minus 2.
Hi !
I’m sorry I won’t be doing the solving for you because it should be easy but I will give you the logic in case you don’t know how to solve them...
Please look at the picture below
According to the theorem we know that DE is:
DE = 1/2 ( BC)
Solve for X then find the values.
Note: remember that if you want to make your life easy multiply both side by 2 to get rid of the 1/2.

x
Step-by-step explanation:
Step 1 :
t
Simplify —
x
Equation at the end of step 1 :
t
(((6 • (s5)) • —) • s4) • t2
x
Step 2 :
Equation at the end of step 2 :
t
(((2•3s5) • —) • s4) • t2
x
Step 3 :
Multiplying exponential expressions :
3.1 s5 multiplied by s4 = s(5 + 4) = s9
Equation at the end of step 3 :
6s9t
———— • t2
x
Step 4 :
Multiplying exponential expressions :
4.1 t1 multiplied by t2 = t(1 + 2) = t3
