Answer:
x=1
Step-by-step explanation:
Use the distributive property on 2(4x - 4), which makes the equation 3x+8x-8=3
Simplify, which makes the equation 11x-8=3
Add 8 to both sides, which makes the equation 11x=11
Divide both sides by 11, which makes the equation x=1
Answer:
1st picture: (0,4)
The lines intersect at point (0,4).
2nd picture: Graph D
2x ≥ y - 1
2x - 5y ≤ 10
Set these inequalities up in standard form.
y ≤ 2x + 1
-5y ≤ 10 - 2x → y ≥ -2 + 2/5x → y ≥ 2/5x - 2
When you divide by a negative number, you switch the inequality sign.
Now you have:
y ≤ 2x + 1
y ≥ 2/5x - 2
Looking at the graphs, you first want to find the lines that intersect the y-axis at (0, 1) and (0, -2).
In this case, it is all of them.
Next, you would look at the shaded regions.
The first inequality says the values are less than or equal to. So you look for a shaded region below a line. The second inequality says the values are greater than or equal to. So you look for a shaded region above a line.
That would mean Graph B or D.
Then you look at the specific lines. You can see that the lower line is y ≥ 2/5x - 2. You need a shaded region above this line. You can see the above line is y ≤ 2x + 1. You need a shaded region below this line. That is Graph D.
Answer:
C. 14 inches
Step-by-step explanation:
The perimeter is double the sum of length and width:
P = 2((4a +3) +(6b -2) = 8a +12b +2
For the given values, this is ...
P = 8(0.75) +12(0.50) +2 = 6 + 6 + 2 = 14
The perimeter is 14 inches.
Answer:
31
Step-by-step explanation:
Lets say Friday papers are x
Saturday papers are 2x
Total cost of Friday papers are .75x
Total cost of Saturday papers are 3x
.75x+3x=116.25
3.75x=116.25
X=31
C = 0.25r
this is becasue quarters have a value of 0.25 and c is the total cents
hope this helps and have a great day! :)
