Answer:
24
Step-by-step explanation:
x=4
f(6*x) becomes f(6*4)
f(6*4)=24
Answer:
2000 eels
Step-by-step explanation:
Let us represent the total estimate of the eels = x
She returns the 50 eels to the lake.
The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.
To solve the above question, we have the following:
50/x = 10/400
Cross Multiply
10x = 50 × 400
x = 50 × 400/10
x = 2000 eels
Therefore, the total estimate of the eels in the lake = 2000 eels
Answer:
9A^2 - 16B^2.
Step-by-step explanation:
(3A+4B)(3A-4B) = 9A^2 + 12AB - 12AB - 16B^2 = 9A^2 - 16B^2.
Hope this helps!
1. x = -5/2
y = 100
25x +10y = 1000 a. Subtract 25x from both sides
-25x -25x
10y = -25x +1000 b. Divide both sides by 10
÷10 <span>÷10
y = -5/2x +100
2. x = -2/5
y = +7
m = slope x= = slope therefore m = x
When it asks for y, it's referring to the y-intercept (expressed as b)
