U take half of the x term and square it....then add to both sides

14/2 = 7.......7^2 = 49...so u add 49 to both sides

Let f(x) = 4x – 1, h(x) = -x-1.<br><br> Find (f o h)(6)<br><br> (foh)(6) =
Ludmilka [50]

Answer:

(foh)(6) = -29

Step-by-step explanation:

(f o h)(6) is f(h(x)) when x = 6.

We have that:

f(x) = 4x - 1

h(x) = -x-1

f(h(x)) = 4(-x-1) - 1 = -4x - 4 - 1 = -4x - 5

(foh)(6) = -4(6) - 5 = -29

(foh)(6) = -29

A truck traveled a distance of 280 kilometers in 4 hrs.
erica [24]
In this question, it is necessary to first check all the details that are already provided in the question. Then after they are noted down the final thing required is to find the answer to the question by correct calculations.
Distance for which the truck traveled = 280 kilometers
Time taken to travel the given distance = 4 hours.
Then
Speed of the truck = Distance traveled/Time taken
                              = 280/4 km/hr
                             = 70 km/hr
So the truck was traveling at a speed of 70 kilometers per hour. This is the answer to both the questions that have been put up. So there is no need for any kind of second calculation.

Alekssandra [29.7K]

It is given in the question that

Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.

Maximum she can spend is $200. That is

0.45x + 0.58y \leq 200&#10;\\  y< \frac{1}{2} x

And

x\geq 0 , y \geq 0

And that's the required inequalities .
