Answer:
2408
Step-by-step explanation:
The correct answer for this statement would be TRUE. Yes,it is true that the identity function is a linear function. <span>A linear function is a map between two vector spaces that preserves vector addition and scalar multiplication.
</span>this means f(x + y) = f(x) + f(y) and f(xy) = f(x)f(y))
<span>The identity function is the function such that f(x) = x
</span>So by using this example, we can conclude that it is a linear function.
The general rule for a linear equation is y=mx+c where m is the slope or gradient... therefore the slope is 3.
Now we need to get 2 points on the line.
You can easily get the y-int by substituting x=0 into the equation... therefore the y-int is 11... you have one point on the line: (0,11)
Now that you have one point and we know the gradient or slope which is 3, go from the point you have found (0,11) and go up 3 and across 1 to find a second point... then simply rule a line in between the two points.
Answer:
c) 300.9 ft²
Step-by-step explanation:
He has 4 1/4 bags of mulch in his shed to use. Each bag of mulch will cover 70.8 ft².
Hence:
1 bag of mulch = 70.8ft²
4 1/4 bags of mulch = x ft²
Cross Multiply
1 bag × x ft² = 4 1/4 × 70.8
x ft² = 4 1/4 × 70.8/1
x = 300.9 ft²
Option c is correct.
