Step-by-step explanation:
3y +4 =5y -10
2y = 14
y = 7
DEF = (3Y+4)× 2 OR (5Y-10) ×2 OR (5Y-10+ 3Y+4)
Def= (3 ×7+4)×2
=50 degree
Answer:
because it is a decimal so it multiplies 100 by the decimal which is a smaller number, almost like how when you divide it becomes a smaller number.

hope this helps:)
Answer:
Subtract 5x from both sides of the equation.
7y=1−5x
x+4y=−5
Divide each term by 7 and simplify.
y=17−5x/7
x+4y=−5
Subtract x from both sides of the equation.
y=1/7−5x/7
4y=−5−x
y=1/7−5x/7
Divide each term by 4 and simplify.
y=1/7−5x/7
y=−5/4−x/4
y=1/7−5x/7
Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution. (3,−2)

Answer:
C) -1 +21i
Step-by-step explanation:
For many purposes, "i" can be treated as though it is a variable. Collect terms in the usual way.
(-2 +12i) -(-1 -9i) . . . . given
= -2 +12i +1 +9i . . . . use the distributive property to eliminate parentheses
= (-2+1) +(12i +9i) . . . group like terms
= -1 +21i
