Answer:
12.5%
Step-by-step explanation:
4 * 100 / 32 = 12.5
Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8
Answer:
3:5, 4:9, 6:8 those are examples
Step-by-step explanation:
Answer: y= -1/2x + 3.5
Step-by-step explanation:
y=mx+b
Y-3= -1/2(x-1)
y-3= -1/2x+1/2
+3 +3
y= -1/2x + 3.5
Steps:
1. Multiply 4 by 1.5 which equals 6
2. Do 6 times 8
3. Your answer is 48
With volume you have to multiply the length x width x height
