Solution :
Let, equation of line is y = mx + c .
Here, m is the slope( or gradient ) of the line and c is the y-intercept .
Putting point ( -6, -10 ) in above equation, we get :
-10 = -6m + c ...1)
Also, putting point ( -3, -8 ) in above equation, we get :
-8 = -3m + c ...2)
Solving equation, 1) and 2) we get :
[tex]m = \dfrac{2}{3}\ and \ y = - 6[/tex]
Therefore, the gradient for the given x-y table is [tex]\dfrac{2}{3}[/tex] .
How would you graph the solution set of x/6 ≤ -18
Multiply both sides by 6 and you'll end up with x ≤ -108
The graph will involve a closed circle at -108 and shading to the left
See below.
We use a closed circle to include the endpoint -108 itself. If we didn't have the "or equal to" part, then we'd be using an open hole at the endpoint instead.
The shading to the left is to describe values smaller than -108. Overall, the entire thing consists of stuff smaller than -108 or -108 itself.

the area of a circle is 100 square miles. What is the diameter?
Answer:
The diameter of a circle with an area of 100 square miles is 20/√π miles.
Step-by-step explanation:
Area =100 = πr^2.
diameter = d = 2r.
100 = πr^2.
100/π = r^2.
√(100/π) = r.
10/√π = r.
d = 2r.
d = 2 * 10/√π.
d = 20/√π

i. How many American dollar can be exchanged withNRs.57, 376
Answer:
Purchase rate = 553.18 U.S dollar
Selling rate = 547.90 U.S dollars
Step-by-step explanation:
Purchase rate
1 U.S. dollar = NRs.103.72
Selling rate
1 U.S. dollar = NRs.104.32
How many American dollar can be exchanged withNRs.57, 376
Purchase rate
1 U.S. dollar = NRs.103.72
Amount of U.S. dollar = NRs.57, 376 / NRs.103.72
= 553.18164288468
Approximately
553.18 U.S dollar
Purchase rate = 553.18 U.S dollar
Selling rate
1 U.S. dollar = NRs.104.32
Amount of U.S. dollar = NRs.57, 376 / NRs. 104.32
= 547.89915966386
Approximately,
547.90 U.S dollars
Selling rate = 547.90 U.S dollars

Find each indicated measure for circle O
Answer:
Angle A = 41, Arc CE = 42, Angle C = 41, Angle D = 40, Angle ABE = 61
Step-by-step explanation:
Angle A = Arc BD/2 (Inscribed Angle)
Angle A = 82/2
Angle A = 41
Arc CE = 2 x Angle CEB (Inscribed Angle)
Arc CE = 2 x 21
Arc CE = 42
Angle C = Arc BD/2 (Inscribed Angle)
Angle C = 82/2
Angle C = 41
Angle D = Arc AC/2 (Inscribed Angle)
Angle D = 80/2
Angle D = 40
Angle ABE = Arc AE/2
Angle ABE = Arc AC + Arc CE/2
Angle ABE = 122/2
Angle ABE = 61
m < A = [tex]39^{0}[/tex] , mCE = [tex]40^{0}[/tex], m < c = [tex]39^{0}[/tex], m < D = [tex]37^{0}[/tex] m < ABE = [tex]57^{0}[/tex]
What are angles in a circle ?A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around.
a. m < A = [tex]\frac{1}{2}[/tex] mBD
= [tex]\frac{1}{2}[/tex] × [tex]78^{0}[/tex]
= [tex]39^{0}[/tex]
b. mCE = 2m < CBE
= 2 × [tex]20^{0}[/tex]
= [tex]40^{0}[/tex]
c. m < c = m < A = [tex]39^{0}[/tex]
d. m < D = [tex]\frac{1}{2}[/tex] mAC
= [tex]\frac{1}{2}[/tex] × [tex]74^{0}[/tex]
= [tex]37^{0}[/tex]
e. m < ABE = [tex]\frac{1}{2}[/tex] mAC + [tex]\frac{1}{2}[/tex] mCE
= [tex]37^{0}[/tex] + [tex]20^{0}[/tex]
= [tex]57^{0}[/tex]
Hence, m < A = [tex]39^{0}[/tex] , mCE = [tex]40^{0}[/tex], m < c = [tex]39^{0}[/tex], m < D = [tex]37^{0}[/tex] m < ABE = [tex]57^{0}[/tex]

Answer:

Step-by-step explanation:
A= (4-1)^3
simplify A to be 3^3
Which gives us 27
B=(2*3)^2-9
simplify B
first multiply the 2 numbers in paranthesis which gives us 6. raise it to the power of 2 which is 39 and then subtract 9. Gives us 27.
C=15^3*4-12
Simplify the exponent first. 3*4 gives us 12 and 12-12 equals 0. Anything raised to the power of 0=1
If A-B^C is the equation we can write 27-27 raised to the power of 1 which is 0

what is a an expression that contains at least one variable
Answer:
An algebraic expression is a type of expression that contains a variable or variables.
Jim orders prints from a website. The site charges him $6.95 a month and $0.04 for each print he orders.
Enter an equation that can be used to find the number of prints, P, Jim ordered last month if the website charged
him $17.79.
Enter the number of prints Jim ordered last month.
Answer:
271 prints.
Step-by-step explanation:
So to answer the question, we need to first write a formula to find the answer.
We know that the starting price per month is 6.95 dollars.
The full price is 17.79 dollars.
So we can start this off by writing:
17.79=6.95
Now, every time Jim prints, he charges 0.04 dollars. This will add to the orginal cost, which is 6.95. And remember this isnt a single payment, but a payment that varies depending on the amount of paper, p. So we can write this as:
17.79=6.95+0.04p
6.95 wont ever change, hense why it doesnt have a variable. 0.04 however, varies depending on the amount of paper, and thats why we included the variable p.
These two values combined make 17.79, hense why it is on the opposite side of the equals sign.
So, now we need to find how many papers, p, were printed.
To find this, lets just take our equation, and solve for P like an ordinary problem:
17.79=6.95+0.04p
So first off, lets subtract the 6.95 from both sides, because that iscolates the 0.04p, which contains the variable.
Now we have:
10.84=0.04p
Now, we could divide both sides by 0.04.
But remember, the whole point of doing this is to make 0.04p into 1p.
So another way of doing this is multiplying the 0.04 by 25, since 0.04*25=1.
So lets multiply both sides by 25:
10.84*25 is 271.
Since 10*25 is 250
And
.84*25 is 21.
So now we know:
271=1p
So 271 is your answer!
Hope this helps!
The equation that can be used to find the number of prints, p, is $17.79 = $6.95 + $0.04p and Jim ordered 271 prints last month.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We can write an equation to represent the total cost that Jim was charged by the website for last month's prints, p to represent the number of prints he ordered:
Total cost = Monthly fee + Cost per print x Number of prints
Using the values given in the problem:
$17.79 = $6.95 + $0.04p
To solve for p, one side of the equation. First, we can subtract $6.95 from both sides:
$10.84 = $0.04p
Then, we can divide both sides by $0.04:
p = 271

Answer:
The inverse is 5/(2-x)
Step-by-step explanation:
Firstly, let us represent the inverse as y
thus;
y = (2x+ 1)/x-4
y(x-4) = 2x + 1
xy - 4 = 2x + 1
2x - xy = -4-1
2x-xy = -5
x(2-y) = 5
x = 5/2-y
Now, switch the alphabets again

Answer:
Radius
Step-by-step explanation:
Any segment with one endpoint at the center of the circle and the other endpoint on the circle is the radius. This information is very important, because when you want to find the area of a circle you multiply the radius by itself twice then multiply that by pi. The diameter (second option) is a segment where one endpoint is on the circle and the other endpoint is on the other side of the circle. The diameter is twice the radius. Good luck!
Out of 200 students in a school, 30 have brown sandals. What is the probability that a student chosen at random would have brown sandals?
Answer:
There is a 15% chance a student chosen at random would have brown sandals.
Step-by-step explanation:
The required probability will be 0.15 that a student chosen at random would have brown sandals.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
the probability = number of favorable outcomes / total number of outcomes.
We have been given that out of 200 students in a school, 30 have brown sandals.
To determine the probability that a student chosen at random would have brown sandals.
The probability = number of favorable outcomes / total number of outcomes.
The probability = 30 / 200
The probability = 0.15
Thus, the required probability will be 0.15 that a student chosen at random would have brown sandals.
