Answer:
O f(x) = -x-1
Step-by-step explanation:
We want to isolate the 'y' variable, so we will subtract 7 from both sides.
y = x + 6 - 7
y = x -1
Answer:
D
Step-by-step explanation:
If he travels 230 miles on 10gallons of fuel, then he will travel 23 miles on 1 gallon of fuel. So it is 230 gallons to one mile.
Answer:
Step-by-step explanation:
Simply plug each x value into the equation
1.
-3, 0, 3, 6, 8, yes it is linear, it doesn't have any exponents
2.
Same thing
5,2,1,2,5, it has exponenets and is not linear
opposite sides and diagonals of a parallelogram are equal
+ diagonals of a parallelogram meet eachother in the middle so:
10x+14=x+77
10x-x=77-14
9x=63
x=63÷9
x= 7
y+8=4y-19
y-4y=-19-8
-3y=-27
y=-27÷-3
y=9
2z+3=37
2z=37-3
2z=34
z=34÷2
z=17
31.25/5=50/8. Divide 31.25 by 5 you get 6.25. Divide 50 by 8 you get 6.25. The constant ratio is: 6.25=6.25 :)
