Answer:
The point of intersection is (2, -1).
Step-by-step explanation:
At the point of intersection both equations have same value of x and y.
y = x - 3
y = 1 - x
Since the 2 right sides are both = y:
x - 3 = 1 - x
x + x = 1 + 3
2x = 4
x = 2.
Substituting for x in equation 1:
y = 2 - 3 = -1.

The total number of people is 5 people if each person gets a ticket a popcorn, each price should be multiplied by 5 or the prices could be added then multiplied by 5.
So, the correct answers are:
5(5.50) + 5(3.25)
5(5.50 + 3.25)
5(5+3) + 5(0.50 + 0.25)
A concert is $250 per ticket and the cost of parking is free. This is expressed
as p(x) = 250x. If the profit is $6,000 how many tickets were sold?
Answer:
24
Step-by-step explanation:
p(x) = 250x
6000 = 250x
x = 24
Answer:
24 tickets
Step-by-step explanation:
p(x) = 250x
Substitute 6,000 for p(x)
6,000 = 250x
Divide each side of the equation by 250
24 = x

A car travels a distance of 330 km at an average speed of 110
km/h. How long does it take the car to travel this distance?
4.3
Calculate the amount that will be in the bank after 4 years if
R2000 was invested at 9% p.a. simple interest
Answer:
4.1 -
300/22= 13.65
so the answer is 13.63
4.2
distance/speed
330/110= 3
So it'll take 3 hours
4.3
sorry not sure for this one :(
4.1
Cost of 22ltrs of petrol = Rs300
Cost of 1ltr of petrol = 300/22
= 150/11
= Rs13.63
4.2
distance = 330km = d
speed = 110km/hr = s
time = d/s
= 330/110
= 33/11
= 3hrs
4.3
SI = principal amount × rate of interest × time
[tex] = 2000 \times \frac{9}{100} \times 4[/tex]
[tex] = 20 \times 9 \times 4[/tex]
[tex] = 720[/tex]
Amount = Principal + SI
= 2000 + 720
= Rs2720

What is the equation of a line perpendicular to y=-2/5X-1 that passes through (2,-8)
Answer:
[tex]y=\frac{5}{2}x-13[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-\frac{2}{5}x-1[/tex]
comparing the equation with the slope-intercept form[tex]y=mx+b[/tex]
Here,
m is the slope b is the interceptso the slope of the line is m = -2/5
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,
so the slope of the perpendicular line will be: 5/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-8\right)=\frac{5}{2}\left(x-2\right)[/tex]
[tex]y+8=\frac{5}{2}\left(x-2\right)[/tex]
subtract 8 from both sides
[tex]y+8-8=\frac{5}{2}\left(x-2\right)-8[/tex]
[tex]y=\frac{5}{2}x-13[/tex]

A rectangular prism has the following dimensions. The base has sides that are 3 cm. and 5 cm. and the height is 9 cm. How many squares with 1 cm edges can cover the entire surface area of the prism completely with no overlaps?
Answer:
174 squares
Step-by-step explanation:
I would start by finding the surface area of the rectangular prism. You can use 2(wl+hl+hw).
2(wl+hl+hw)
2(3*5+9*5+9*3)
2(15+45+27)
2(87)
174 cm^2
The area of squares 1 cm edges would be 1 because 1*1=1, so you could find how many of them would fit on the surface area by dividing 174 by 1, which equals 174.
.Solve for x.
3x = -39
Answer:
x= (-13)
Step-by-step explanation:
You need to get x alone so you have to divide by 3 and -39/3 equals -13
Answer:
x = -13
Step-by-step explanation:
Divide both numbers by 3
3÷3 cancels each other out, leaving x
-39÷3= -13
