Answer:
See the attached for a graph.
Step-by-step explanation:
The edge of the solution space is marked by the line ...
... y = 4 - 2x
This is in slope-intercept form. It has a y-intercept of 4 and a slope of -2. Because the relation symbol is "less than" (with no "or equal to"), the line itself is not part of the solution space. It is graphed as a dashed line for that reason.
The values of y in the solution space are those <em>less than</em> the ones that make up the line, so the shading is of the half-plane <em>below</em> the line.
Answer:
Mean of a grouped data is
Sum of F x/ sum of frequency F
Sum of F = 5 + 15 + 13 + 10 + 7 = 50
to find x find the average of the two classes
That's
0 + 10/2 = 10/2 = 5
10+20/2 = 15
20 + 30 / 2 = 25
30+40 /2 = 35
40+ 50 / 2 = 45
Therefore sum of Fx = 5(5) + 15(15) + 13(25) + 10(35) + 7(45)
= 1240
Therefore
Mean = 1240/50
= 24.8cm

Answer:
Step-by-step explanation:
.25 mile in 2 mins
.25(5) miles in 10 min
1.25 mins in 10 mins
There is 5-2 mins in 10 mins. So times by the 5.
Answer:
x=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−x=2−3x+6
Step 1: Simplify both sides of the equation.
−x=2−3x+6
−x=2+−3x+6
−x=(−3x)+(2+6)(Combine Like Terms)
−x=−3x+8
−x=−3x+8
Step 2: Add 3x to both sides.
−x+3x=−3x+8+3x
2x=8
Step 3: Divide both sides by 2.
2x/2 = 8/2
x=4
Answer:
A) y = 6x + 8
