The first answer is 25x + 45 = c
The second one is y=3x
Hopes this helps
To find the correct function, just plug in 10 and 2 to see if the function equals zero with both numbers.
f(x)=x^2-12x+20
f(10)=100-120+20
f(10)=0 --> that's what we want, so let's check the other number
f(x)=x^2-12x+20
f(2)=4-24+20
f(2)=0 --> perfect. this function has zeros at both x=10 and x=2
The function that has zeros at both x=10 and x=2 is f(x)=x^2-12x+20.
1) Unknown info = amount of potting soil he bought last week
2). 28=2x+4
Where x=amount of potting soil he bought last week
3). 28=2x+4
-4 -4
---------------------
24=2x
/2 /2
----------------------
X=12
4) Emmanuel bought 12 lbs of potting soil last week
Answer:
700 miles
Step-by-step explanation:
Since the scale is 0.5 and she's 7 inches away on the map, you divide 7 by 0.5 and get 14. Then, you multiply 14 by 50 because each inch is 50 miles.
What you meant was range. The range scales from top to bottom. You can know this by graphing and practicing memorizing these function's domain and range.
Function: Range:
f(x) = -√x y ≤ 0
p(x) = ∛2-x All real numbers
w(x) = 2 + √x y ≥ 2
r(x) = -2 + √2-x y ≥ -2
k(x) = 2 - √x y ≤ 2
v(x) = √-x y ≥ 0
