Answer: EQUAL
Step-by-step explanation:
Just as you can do the same thing to both sides of an equation, you can do the same thing to both sides of a fraction. 15 = 5*3 and 21 = 7*3. Thus, 5/7=15/21
Hope it helps <3 :)
X value is going up and y value is moving up and down. So, it`s look like a quadratic function. y intercept is 12 and x intercept is 2 and 6. and vertex is (4,-4). than f(x)= a(x-4)^2+4. and put (0,12). and 16a+4=12. a=1/2. f(x)=1/2x^2-4x+12 or 1/2(x-4)^2+12
49 each! 49+49= 98
Hoped this helps! Mark as branliest if possible!
Answer:
A. She wrote 19 numbers
B. She wrote 12 numbers
C. She wrote 29 digits
Step-by-step explanation:
To find haw many numbers from x to y subtract x and y and then add 1
- Ex: There are 6 numbers from 1 to 6 because (6 - 1) + 1 = 6 (1, 2, 3, 4, 5, 6)
To find how many numbers between x and y subtract x and y then subtract 1
- Ex: There are 4 numbers between 1 and 6 because (6 - 1) - 1 = 4 (2, 3, 4, 5)
The numbers from 1 to 9 have one digit and from 10 to 99 have two digits
A.
∵ Mary wrote all the integers from 1 to 19
∵ (19 - 1) + 1 = 19
∴ She wrote 19 numbers
B.
∵ Rena wrote all the integers from 1 to 12
∵ (12 - 1) + 1 = 12
∴ She wrote 12 numbers
C.
∵ Mary wrote all the integers from 1 to 19
∵ From 1 to 9 the numbers have one digit
∵ There are 9 numbers from 1 to 9 because (9 - 1) + 1 = 9
∴ The number of digits from 1 to 9 = 9 × 1 = 9 digits
∵ There are 10 numbers from 10 to 19 because (19 - 10) + 1 = 10
∵ From 10 to 19 each number has 2 digits
∴ The number of digits from 10 to 19 = 10 × 2 = 20 digits
∴ The number of digits from 1 to 19 = 9 + 20 = 29 digits
∴ She wrote 29 digits
Answer:
(x-1)²+(y+4)²=3²
Step-by-step explanation:
The formula for a circle on a graph is standard form is:
(x – h)² + (y – k)² = r²
(h,k) being the center point of the circle.
r=radius
The answer for the equation of this circle in standard form is:
(x-1)²+(y+4)²=3²
