Answer:
[tex]y=5x+3[/tex]
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
1) Plug the given slope 5 into the equation
[tex]y=mx+b\\y=5x+b[/tex]
2) Find the y-intercept [tex]b[/tex] by plugging in the point (-1,-2)
[tex]y=5x+b\\-2=5(-1)+b\\-2=-5+b[/tex]
Add 5 to both sides
[tex]-2+5=-5+b+5\\3=b[/tex]
3) Plug the y-intercept back into the equation
[tex]y=5x+3[/tex]

What is the exact area of a circle with a radius of 12 feet? 24π Square Feet 36π Square Feet 121π Square Feet 144π Square Feet Question 2. What is the approximate area of the circle? Use π = 3.14 (the circle has 10.4 inside it) 32.7 square centimeters 65.2 square centimeters 108.2 square centimeters 339.6 square centimeters Question 3. What is the approximate area of a circle with a radius of 28 centimeters? Use π = 3.14 87.9 square centimeters 175.8 square centimeters 2461.8 square centimeters 4923.5 square centimeters Question 4. What is the approximate area of a circle with a diameter of 50 centimeters? Use π = 3.14 87.9 square centimeters 379.9 square centimeters 1962.5 square centimeters 4923.5 square centimeters
Answer:
144πfeets² ; 339.6 cm² ; 2461.8 cm² ; 1962.5 square centimeters
Step-by-step explanation:
Area of a circle, A = πr²
1.)
with a Radius of 12 feets
A = π * 12² = 144πfeets²
2.)
Approximate area :
3.14 * 10.4² = 339.6224 feet²
3.)
with a Radius of 28 cm
A = 3.14 * 28² = 2461.76cm²= 2461.8 cm²
4.
Diameter = 50 cm ; Radius = 50/2 = 25
with a Radius of 25 centimeter
A = 3.14 * 25² = 1962.5 cm²
what is the value of x and y?
Answer:
The right answer is x = 8, y = 40.
Step-by-step explanation:
Since this triangle is isosceles we know that...
∠ACB = ∠ABC
40° = (5x)°
40 = 5x
x = 40 / 5
x = 8
We also know that the sum of all angles inside the triangle is equal to 180°, therefore...
∠BAC = 180° - ∠ACB - ∠ABC
(2y + 20)° = 180° - 40° - 40°
2y + 20 = 100
2y = 100 - 20
2y = 80
y = 80 / 2
y = 40
From this, we know that the right answer is x = 8, y = 40.

Answer:
It is answer 3
Step-by-step explanation:
a. What is the circumference of the
largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for T.
b. What percent of the perimeter of the
square is the circumference of the
circle?
Answer:
Step-by-step explanation:
a. The diameter of the circle will be 30 cm

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?
Answer: 10 people
Step-by-step explanation:
Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.
The amount spent on just tickets is therefore:
= 243.25 - 15.75
= $227.50.
If $227.50 was for tickets alone, the number of tickets they could buy is:
= Total amount left/ Price of tickets
= 227.50 / 22.75
= 10 people

find the simple interest principle 950 interest rate 12% time 4 years
Answer:
A= $1406
Step-by-step explanation:
The formula for simple interest is A=P(1+rt), where P=Principal, R=Rate, and T=Time. Before you plug your numbers into your formula, you must first convert 12% to a decimal (This is simple because all you have to do is divide 12 by 100.)- 0.12.
Now, you can plug your numbers into the formula: A=950(1+0.12x4). To make this less complex, I suggest working in the parenthesis first- specifically simplifying rt, or multiplying 0.12 by 4 (you should get 0.48)! Now, you are just about ready to go. A=950(1+0.48)- You can plug this into your calculator as is, or you can go on ahead and add the numbers in the parenthesis if that makes you feel better! (You should get 1.48).
Your final formula should be 950(1.48), and you should plug this into a TEACHER-APPROVED CALCULATOR to save time!
Your final answer should be $1406, otherwise you did something wrong! XD!

Find the length of midsegment JN in the trapezoid.
Answer:
JN = 18.6
Step-by-step explanation:
Theorem: The length of the midsegment of a trapezoid is the average of the bases.
[tex]JN = \frac{15.4 + 21.8}{2}[/tex]
[tex]= \frac{37.2}{2}[/tex]
= 18.6
See how easy that is when you know the theorem.
find the value of x in a triangle. x-20, x+10, x-20
The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)
Sum of all the interior angles of a triangle is 180°.
So a equation can be made by the given data,
(x-40°) + (x-20°) + (½ x-10°) = 180°
x-40°+x-20°+½x-10° = 180°
2x+½x -60°-10° = 180°
5/2 x - 70° = 180°
5/2 x = 180° + 70°
5/2 x = 250°
x = 250° × 2/5
x = 50° × 2
x = 100°
So the angles are
x-40° = 100°-40° = 60°
x-20° = 100°–20° = 80°
½x-10° = ½(100)° - 10° = 50° -10° = 40°
The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.
60° + 80° + 40° = 100° + 80° = 180°
