W=28
Answer:
-8
Step-by-step explanation:
Given that x and y are two variables. they are related by the function
y =8-2x
Since x and y are related, given one value we can find the other using this equation.
In our question, given that x =8
Substitute x value in the equation
y = 8-2x
y =8-2(8) = -8
Hence answer is -8:
Verify: We verify by putting -8 for y and check whether x =8
-8=8-2x
Or 2x = 16
x =8

Volume liquid = volume of the cone = 1/3 * pi * r^2 * h = 1/3 *3.14 * 1^2 * 9
= 9.42 in^3
so total value = 2 * 9.42 = $18.84
Find the unit rate. He drove 168 miles in 4 hours.
168/4= 42
He drives 42 Mph.
Multiply that by 7.
42*7= 294
He drives 294 in 7 hours.
I hope this helps!

Answer:
Solution set = (-5, -2)
Step-by-step explanation:
Given equations;
-7x + 8y = 19 ------------- eq1
7x – 9y=-17 --------------- eq2
Adding both equations:
-y = 2
OR
y = 2
Put value of y in eq2:
7x - 9(-2) = -17
7x + 18 = -17
7x = -17 -18
7x = -35
x = -5
Solution set = (-5, -2)
i hope it will help you!
