Yes, u did it correctly.
estimate : 10 - (6 + 2) = 10 - 8 = 2
exact : 10 - (5.95 + 1.75) = 10 - 7.70 = 2.30
Should be 21 boys because 7+7+7 equal 21 and 3+3+3 equal 9 which equals 30
Answer:
y = (x - 5)² - 2
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (5, - 2), thus
y = a(x - 5)² - 2
To find a substitute (7, 0) into the equation
0 = a(7 - 5)² - 2
0 = 4a - 2 ( add 2 to both sides )
2 = 4a ( divide both sides by 4 )
a = =
y = (x - 5)² - 2 ← in vertex form
Answer:
13+10x
Step-by-step explanation:
i believe thats a multiplication sign so you multiply 3 and two and get six then you add 7 and get 13 and you cant simplify more so the answer is 13 +10x
Answer:
2194.8
First, 124 times 2.95 then you get 365.8 and finally you multiply by 6 and get you answer.
