A scuba diving resort hotel offers divers two plans. Plan A gives 3 nights’ lodging and 4 dives. Plan B gives 5 nights’ lodging and 8 dives. How much does it cost for each night and each dive?
Answer:
x = 35 and y = 100
Step-by-step explanation:
Let x = dollar cost per dive and y = dollar cost per night.
ATQ,
4x+3y = 440 .....(1)
and
8x + 5y = 780 .....(2)
Multiply equation (1) by 2.
8x+6y = 880......(3)
Subtract equation (3) from (2).
8x + 5y -(8x+6y)= 780-880
-y = -100
y = 100
Put the value of y in equation (1).
4x+3(100) = 440
4x = 440-300
4x = 140
x = 35
Hence, the value of x is 35 and that of y is 100.

the profit equation for a manufactioring company is p=x^2-2500 where p is profit, and x is number of units sold. For what number of units sold does the company break even? (p=0)
Answer:
For the company to break even, the number of units sold is 500 units
Step-by-step explanation:
To get this number of units, we simply substitute the value of 0 for p
we have this as;
0 =x^2 -2500
x^2 = 2500
x = √2500
x = 500 (we do not consider the other root of x = -500 since the number of quantities cannot be negative)

Answer:
2.95 cans of soup
Step-by-step explanation:
A large can of soup contains 19 fl oz A serving is about eight Oz How many Canz should you buy if you want to serve How many Cans should you buy if you want to serve 7 people
Step 1
From the above question:
1 serving = 1 Person
1 person = 8oz
7 persons = x
Cross Multiply
x = 7 × 8oz
x = 56 oz
Step 2
56 oz will serve 7 people
M
From the question also, we are told that:
19 oz = 1 can of soup
56 oz = x
Cross Multiply
19x = 56 × 1
x = 56 /19
x =2.9473684211 cans of soup
Approximately
2.95 cans of soup will serve 7 peop

Circle A is located at (6, 5) and has a radius of 4 units. What is the equation of a line that is tangent to circle A from point C (2, 8)?
x = 2
y = −0.75x + 9.5
y = 1.33x + 1.66
x = 8
Answer:
x=2
Step-by-step explanation:
got it right on the test i promise
The equation of the line that is tangent to circle A from point C (2, 8) is x = 2 option (A) x = 2 is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
Circle A is located at (6, 5) and has a radius of 4 units.
First, find the slope of the radius
As we know, the ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The line passes through (2, 8) and (2, 5)
y - 5 = (-3/0)(x -2)
-x + 2 = 0
x = 2
Thus, the equation of the line that is tangent to circle A from point C (2, 8) is x = 2 option (A) x = 2 is correct.

Stefan sells Jin a bicycle for $125 and a helmet for $18. The total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
Answer:
Stefan originally spent $ 110 on the bike and helmet, with which he is making a profit of $ 33.
Step-by-step explanation:
Since Stefan sells Jin a bicycle for $ 125 and a helmet for $ 18, and the total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet, to determine how much did Stefan spend originally and how much money did he make by selling the bicycle and helmet to Jin, the following calculations must be performed:
130 = 125 + 18
100 = X
100 x (125 + 18) / 130 = X
100 x 143/130 = X
14,300 / 130 = X
110 = X
143 - 110 = 33
Therefore, Stefan originally spent $ 110 on the bike and helmet, with which he is making a profit of $ 33.

If you apply the changes below to the linear parent function, fx) = x, what is
the equation of the new function?
• Vertically stretch by a factor of 4.
• Flip over the x-axis.
O A g(x) = - 1/4 x
B. g(x) = -1/4x-1
O C. g(x) = -4x
O D. g(x) = 1/4x
Answer:
C
Step-by-step explanation:
A vertical stretch is accomplished by multiplying the parent by the stretch factor (given as 4 in this problem). At that point, the function is
h(x) = 4x
To flip over the x-axis, change the sign of the function's rule.
g(x) = -4x
In the attached image, f(x) = x is purple, h(x) = 4x is black, g(x) = -4x is red.

Step-by-step explanation:
In graph 1, there is no x-y correlation
In graph 2, there is, when x=1, y=6
when x=2, y=12. Therefore, when x=3 y would equal 18.

What is the equation of a line with a slope of 4 and a y-intercept of 2?
Answer:

Step-by-step explanation:
This is because the equation format for a line is y=mx+b, the slope is m and the y-intercept is b. So all you have to do is fill it out to get y=4x+2. Or the other way I listed the equation is right too. Hope this helps!
