The sum of a number is the answer to an equation of a number plus a number you are correct.
Answer:
N0 solution.
Step-by-step explanation:
x=-2y+1....(1)
x+2y=9....(2)
put equation (2) to equation (1)
-2y+1 + 2y=9
combine
-2y + 2y=9-1
0=8
No solution.
Answer:
G
Step-by-step explanation:
-3
substitute the value of g into f, evaluate the result function by replacing x with 4 in the function.
Answer:
X=18.5
Y=37
Step-by-step explanation:
DOB=16° because it's a vertical pair. Because COF is 90°, that means 4x+16 is also 90.
4x+16=90, subtract 16
4x=74, divide by 4
x=18.5
Because EOA is 90°, and you know DOB is 16°, you can set 2y+16 equal to 90 as well.
2y+16=90, subtract 16
2y=74, divide by 2
y=37
