Answer:
4 hours
Step-by-step explanation:
Write an equation
19 +1.5x < 15+2.75x
Subtarct 15 on both sides
4+1.5x<2.75x
subtract 1.5x on both sides
4< 1.25x
Divide 1.25 on each side
3.2<X
Since they on,y charge per hour so 4 hours
f(x) as a linear equation:
gradient = (12-4)/(4-2) = 4
y - 4 = 4(x - 2)
y = 4x - 4
Therefore f(x) = 4x - 4
g(x) = 10x - 4
Since it already started at 10 and it increases by one every level (x):
h(x) = x + 10
Therefore, since g(x) has the largest gradient (10x), it has the largest slope
Answer:
21x² - 7x - 28
Explanation:
To answer this question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(3x - 4)(7x + 7)
3x(7x) + 3x(7) - 4(7x) - 4(7)
21x² + 21x - 28x - 28
21x² - 7x - 28
Hope this helps :)
Answer:
<u>35</u>
Step-by-step explanation:
well, you know the angles of a triangle add up to 180 degrees, and you have the other 2 degrees right there, so all you have to do is add both of the other angles 111+34= 145 and then subtract by 180, 180-145=35 so your answer is 35
