Answer:
y=3x-10
Step-by-step explanation:
For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.
(y-y1)=m(x-x1)
(y-2)=3(x-4)
y-2=3x-12
y=3x-10
To check, you can plug the coordinates into the equation.
y=3x-10
(2)=3(4)-10
2=12-10
2=2
Answer:
Randy just added up the numbers on the numerator and denominator.
This is incorrect.
<u>Correct way of adding the fractions given below:</u>
- 7/8 + 9/15 = ⇒ Simplify the second equation, divide by 3)
- 7/8 + 3/5 =
- 5*7/5*8 + 8*3/8*5 = ⇒ Bring both fractions to common denominator of 40
- 35/40 + 24/40 = ⇒ Add up the numbers in the nominator
- 54/40 = ⇒ Simplify by dividing by 2
- 27/20 =
- 1 7/20 ⇒ Convert to mixed fraction
Answer:

Step-by-step explanation:
The perimeter of a circle is the circumference of the circle. To find it, use the formula
.
The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.
Substitute into the formula.

Find the area of the larger rectangle.
5 x 4 = 20
One of the triangles is 2 x 2. Area of 2. Subtract 2 from 20.
20 - 2 = 18
Another is 2 x 5. Area of 5. Subtract 5 from 18.
18 - 5 = 13
The last is 3 x 4. Area of 6. Subtract 6 from 13.
13 - 6 = 7
The area of the triangle QRS is A, 7.
Hope this helps!
