Step-by-step explanation:
If two lines have the same slope and the same y-intercept, there are infinite solutions.
If two lines have the same slope and different y-intercepts, there are zero solutions.
Otherwise, if the two lines have different slopes, then there is one solution.
The slope of the first line is 3/8. The slope of the second line is 16/32 = 1/2. The slopes are different, so there is only one solution.
The solution of the given system of equations is (x, y) = (8.75, 2).
What is a Linear equation of two variables?These are the system of equations with two variables having a no solution, unique solution or infinitely many solutions.The highest order of the equation for this systems is one.Given: System of equations
3x - 8y = 10 …(1)
16x - 32y = 75 …(2)
Consider equation (2).
⇒ 16x - 32y = 75
Dividing both sides by 16, we get:
⇒ x - 2y = 75/16
⇒ x = 2y + 75/16 …(3)
Now, substitute the value of x = 2y + 75/16 in equation (1), we get:
⇒ 3(2y + 75/16) - 8y = 10
⇒ 6y + 225/16 - 8y = 10
⇒ 2y = 225/16 - 10
⇒ 2y = (225 - 160)/16
⇒ 2y = 65/16
⇒ y = 65/32
⇒ y ≈ 2
Now, put the value of y = 65/32 in equation (3), we get:
⇒ x = 2(65/32) + 75/16
⇒ x = (65/16) + (75/16)
⇒ x = 140/16
⇒ x = 8.75
Therefore, the solution for the given simultaneous equation is;
(x, y) = (8.75, 2)

A surf instructor has an initial fee of $12 and charges $8 per hour for lessons,
explain how to determine what the y-intercept is and where it would be located on a graph.
Please help me, i'm stupid and i don't know where, or how to find this.
Answer:
I am stuck on that question tooo
Step-by-step explanation:
Step-by-step explanation:
First, let's write an equation.
h= numbers of hours, the instructor will charge $8 per hour.
s= amount of $
"12" is the initial fee.
From this information the equation will look like:
s=8h
However, on our graph, we will have to start on 12 since this was the initial fee. (so on the y, put a dot on 12.)
I think that (0, 12) is the y-intercept but I'm not entirely sure. In reality, your graph can't have any negative h(x) or y(s) values so the graph would be shaped like an "L".

(a) Olivia deposits $8600 in a bank. The interest rate is 2.6% per annum.
Find the total interest she will earn in 4 years.
Answer:
Below in bold.
Step-by-step explanation:
You do not say if the interest is simple or compound.
Simple Interest: I = PRT/100
= (8600* 2.6 * 4)/ 100
= $894.40.
Compound Interest:- amount after 4 years
= 8600(1 + 0.026)^4
= $9529.89
So the compound interest
= 9529.89 - 8600
= $929.89.

for a rs 4444. At what price
sold to gain
should it be
rs 444?
Answer:
Hence, the watcg must be bought at rupees 4888
Step-by-step explanation:
Let the desired selling price of the watch be x
Cost Price of the watch = 4444
We know that if Cost Price < Selling Price,
Selling Price - Cost Price = gain
When we substitute we get,
x-4444=444

Explain how you can write an equation for the given situation in standard form. One number is 5 more than a second number. The product of the two numbers is 891.
A) Let x be the smaller number, and then x+5 is the larger number. This means that x(x+5)=891, which can be rewritten as x^2+5x-891=0
B) Let x be the smaller number, and then x+5 is the larger number. This means that x+(x+5)=891, which can be rewritten as 2x-886=0
C) Let x be the smaller number, and then x+5 is the larger number. This means that x(x+5)=891, which can be rewritten as x^2+5x+891=0
D) Let x be the smaller number, and then x+5 is the larger number, This means that x+5/x=891, which can be rewritten as 890x-5=0
Answer:

The length of a rectangular room is 8 feet more than twice the width. If takes perimeter of the room is 124 feet, what are its dimensions?
Hey there! I'm happy to help!
Let's call the length and width L and W respectively.
L=2W+8
2W+2L=124
We plug our value of L into the second equation and solve for W.
2W+2(2W+8)=124
We undo the parentheses with the distributive property.
2W+4W+16=124
Combine like terms.
6W+16=124
Subtract 16 from both sides.
6W=108
Divide both sides by 6.
W=18
We plug this W value into the first equation to solve for L.
L=2(18)+8
L=36+8
L=44
So, the length is 44 feet and the width is 18 feet.

Points P, Q, R, and S are collinear. Point Q is between P and R, R is between Q and S, and PQ =RS. If PS = 21 and PR = 16, what is the value of QR? QR = (Simplify your answer.)
Greetings from Brasil...
→ Collinear points = points belonging to the same line
→ PQ is said to be equal to RS. Let’s call this distance X
→ let's call QR Y
With this information and the figure in the annex we can conclude that:
refer to attached
PQ = X
QR = Y
RS = PQ = X
then
PR = PQ + QR
16 = X + Y i
PS = PR + RS
21 = 16 + X
X = 5 putting in i
16 = X + Y
16 = 5 + Y
Y = 11
So,
PQ = 5QR = 11RS = 5Collinear points are points on the same line.
The value of QR is 11
From the question, we have:'
Q between P and RR between Q and SThis means that:
[tex]\mathbf{PR = PQ + QR}[/tex]
[tex]\mathbf{QS = QR + RS}[/tex]
[tex]\mathbf{PS = PR + RS}[/tex]
The given parameters are:
[tex]\mathbf{PS = 21}[/tex]
[tex]\mathbf{PR = 16}[/tex]
[tex]\mathbf{PQ = RS}[/tex]
Substitute the above values in [tex]\mathbf{PS = PR + RS}[/tex]
[tex]\mathbf{21= 16 + RS}[/tex]
Solve for RS
[tex]\mathbf{RS = 21- 16}[/tex]
[tex]\mathbf{RS = 5}[/tex]
This means that:
[tex]\mathbf{PQ = RS = 5}[/tex]
Substitute 5 for PQ in [tex]\mathbf{PR = PQ + QR}[/tex]
[tex]\mathbf{PR = 5+ QR}[/tex]
Substitute [tex]\mathbf{PR = 16}[/tex] in [tex]\mathbf{PR = 5+ QR}[/tex]
[tex]\mathbf{16 = 5+ QR}[/tex]
Solve for QR
[tex]\mathbf{QR = 16 - 5 }[/tex]
[tex]\mathbf{QR = 11}[/tex]
Hence, the value of QR is 11

what will be number of zeros in the square of the number 100? pls answer fasttttttttttt
Answer:
4
Step-by-step explanation:
The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000
Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.
So, the number 10,000 which is the square of 100 has 4 zeros.

40. A pendulum in a museum swings through
an angle of 60° in 17.3 s. The linear velocity
of the pendulum is 1.32 ft/s. Determine the
length of the pendulum.
Answer:
21.81 ft
Step-by-step explanation:
For an arc of measure α and radius r, the arc length is ...
s = r·α . . . . . . where α is in radians
Then the linear speed is ...
s' = r·α'
Here the rate of change of arc angle is (π/3)/(17.3) rad/s, so the radius can be found to be ...
r = s'/α/ = (1.32 ft/s)/((π/3)/17.3 rad/s) = 1.32·3·17.3/π ft
r ≈ 21.81 ft
The length of the pendulum is about 21.81 feet.

Julie and her family go to the movies. They buy 2 adult tickets and 3 child tickets. An adult ticket costs $3.50 more than a child ticket. Julie's family spends $35.75. What is the cost of the adult ticket?
HELP PLS
Answer:
$9.25
Step-by-step explanation:
let x = the cost of a child ticket
3(x)+2(x+3.50)=35.75
3x+2x+7=35.75
5x=28.75
x=5.75 cost of child ticket
5.75+3.50= 9.25
Answer:
$9.25
Step-by-step explanation:
Start by multiplying 2 by 3.5. This will give you 7. Then subtract 7 from 35.75, which gives you 28.75. This is the full amount for five child tickets. Then you want to divide 28.75 by 5, giving you 5.75. This is the amount for a single child ticket, and because we know that an adult ticket is 3.50 more than a child ticket, you add 3.50 and 5.75, which gives you your final answer of 9.25.
