Step-by-step explanation:
<u>Equation Plan A</u>
<u>Equation Plan B</u>
<u>Equating them</u>
- 40x + 860 = 100x + 200
- 60x = 660
- x = 11
- The plans will pay the same at 11 correct questions.
<u>Solving for y using x = 11</u>
- y = 100(11) + 200
- y = 1100 + 200
- y = 2300
- The amount they'll pay at that number of questions is $2,300
<u>Comparing both plans when x = 13</u>
- Plan A : 40(13) + 860 = 520 + 860 = $1,380
- Plan B : 100(13) + 200 = 1300 + 200 = $1,500
- As Plan B pays more, that is the plan you should choose

Step-by-step explanation:
There needs to be the source of which this question is coming from.
Both angles added together equal 180 degrees.
B = 180 - 45 = 135 degrees.
Answer:
g(x)=x+6
Step-by-step explanation:
we have
f(x)=x+8
If f(x) is shifted 2 units to the right
then
The rule of the translation is
g(x)=f(x-2)
so
g(x)=(x-2)+8
g(x)=x+6
Answer:
This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8). The previously unknown x-coordinate is 16.
Step-by-step explanation:
A line with slope m = -1/5 passes through the points (x, 7) and (11, 8). Find the value of x.
The slope of the line through these two points is found from the slope formula and is:
8 - 7
m = ----------- and the value of m is given as -1/5. Therefore,
11 - x
1
m = ----------- = -1/5
11 - x
Cross-multiplying, we get (1)(5) = -(11 - x), or 5 = -11 + x. Then x = 16
This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8). The previously unknown x-coordinate is 16.
