To prove this, let's take the correct steps:

4.5\div 1/4+2 1/2-.75\times 8 \\ \\ Step \ 1: 18+2 \ 1/2-0.75\times 8 \\ \\ Step \ 2:18+2.5-6 \\ \\ Step\ 3:18-3.5 \\ \\Step \ 4:14.5


As you can see, Leticia makes the first mistake in Step 2, that is,<em> she didn't multiply 8 by 0.75.</em>

The position of a large fish relative to the water surface was −17 1/3 feet. It suddenly dove straight down and increased its de
boyakko [2]
So let’s imagine this on a number line…so we know that the fish starts at -17 1/3 on the number line but he dives (that means go lower in our number line) 6 1/2 feet downward so let’s set up an equation:

-17 1/3 - 6 1/2
Now, let’s subtract the two integers by finding the least common denominator of 2 and 3 so it can be easier to solve in this case it’s 6…then let’s set up our new equation:

-17 2/6 - 6 3/6
We know it’s a negative number since we are subtracting a negative number and our final answer is -23 5/6

If g(x) = -5x + 13, find g(-1)
givi [52]

To solve this problem, we must substitute the value of -1 in for x in the function. This means that for every x there is in the equation, we must substitute the value -1 in for it in order to find the value of g(-1). This is modeled below:

g(x) = -5x + 13

g(-1) = -5(-1) + 13

Next, we must simplify using the order of operations. PEMDAS outlines this concept, telling us to simplify parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. In this case, we will solve the multiplication and then the addition, as modeled below:

g(-1) = -5(-1) + 13

g(-1) = 5 + 13

g(-1) = 18

Therefore, your answer is 18.

Hope this helps!

The table shows the number of
Anna35 [415]

According to the table given, the rate of change is of 9.

The <em>rate of change</em> is given by the <u>change in the output divided by the change in the input.</u>

In this problem:

  • The input is the number of bouquets.
  • The output is the number of flowers.

Taking two of the points, (3,27) and (5,45), we have that:

m = \frac{45 - 27}{5 - 3} = \frac{18}{2} = 9

Hence, the rate of change is of 9, which would be verified taking any pair of two points.
