Answer:4
Step-by-step explanation: y=mx+b is the slope intercept form of an equation. m is the slope and b is the y-intercept. just substitute 4 for m and 2 for b and get the original equation y = 4x + 2. since 4 is m, then 4 is the slope.
Answer:
x = x+9
Step-by-step explanation:
well that is the only way you can do it as we do not know about what x is. also, if you meant by x + (x*9), you can represent that as x*10
(33x+99)+1(−44x+88)
(33x+99)(44x+88)
-33x to 44x and get 11x then subtract 88 to 99 and get 11 the answer should be one
5x+2y=20
Substitute 0.3 for x
5(0.3)+2y=20
Multiply 5 by 0.3
1.5+2y=20
Subtract 1.5 from both sides
2y=18.5
Divide 2 on both sides
Final Answer: y= 9.25
