Answer:
15
Step-by-step explanation:
The line 1 has equation 5x + 6y + 30 = 0. Given
that P is the point (3, -1), find
(i) the coordinates of the point where l crosses the
x-axis,
(ii) the coordinates of the point of intersection
of l with the line x = 2,
(iii) the equation of the line passing through P
and having the same gradient as I,
(iv) the equation of the line passing through P
and having a gradient of 0.
w through the points ACO 3).
Answer:
Step-by-step explanation:
i) the x-intercept is when y=0
5x+6(0)+30=0
5x=-30
x=-6
hence the point is (-6,0)
ii)5(2)+6y+30=0
10+6y+30=0
6y=-40
y=-20/3
hence the point of intersection is (2,-20/3)
iii) y+1=-5/6(x-3)
6y+6=-5x+15
6y+5x=9
iv) y+1=0(x-3)
y=-1

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388

PLEASE ANSWER COMPLETE QUESTION. WILL MARK BRAINLIEST FOR BEST ANSWER. QUESTION IS ATTACHED.
9514 1404 393
Explanation:
A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.
Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.
y = 3x +1y -7 = 3(x -2)If we subtract the first equation from the second, we get ...
(y -7) -(y) = (3(x -2)) -(3x +1)
-7 = 3x -6 -3x -1 . . . . . eliminates y
-7 = -7 . . . . . . . . . true for all values of x
There are an infinite number of solutions.

The graphs below have the same shape. What is the equation of the blue graph? (apologies for bad quality)
Answer:
The blue graph is translated 3 units to the left and two down, so the new equation would be g(x)=(x-3)^2-2
A cylindrical container has a diameter of 5 inches and a height of 12 inches. The container will be wrapped and delivered as a gift. What measurement is closest to the amount of wrapping paper needed to cover the container without overlap?
Answer:
Step-by-step explanation:
1. Write your formula
2. Plug it in
3. Solve
these steps will help you out with all of your surface area problems.
Like this
Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...
V = Bh (Pie is also known as 3.14)
your big (B) is (pie times r squared) Then you add your height.
so your formula will look like this...
V = pie times r squared...
the full formula will be...
V = (3.14) times (2.5 squared) times the height which in this case is (12)
everything together will be...
V = (3.14) (2.5^2) (12)
all you have to do is multiply all of that and you will get your answer.
The answer is...
V = 236 inches ^2 (Just a tip, the ^ sign means to the power of)
At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 12 m. The inner edge of the sidewalk is a circle with a radius of 8 m.
Write and simplify an expression for the exact area of the sidewalk.
Find the approximate area of the sidewalk. Use 3.14 to approximate π.
Answer:
The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m
The equation would be:
144 x 3.14 - 64 x 3.14 = 251.2
Step-by-step explanation:
First, you need to find out what the whole circle is:
The whole circle is 452.16
Then, find the inner circle :
8 x 8 x 3.14
200.96
Last, subtract the whole by the inner:
452.16 - 200.96 = 251.2

(4m+3)(m+2)
expand each of the following algebraic expression
Answer:
4m² + 11m + 6
Step-by-step explanation:
Use foil to expand this value.
(4m+3)(m+2)
Multiply the first terms in the two brackets.
Then multiply the two outer terms.
Followed by multiplying the inner terms.
Finally multiply the last terms
= (4m+3)(m+2)
4m² + 8m + 3m + 6
4m² + 11m + 6
