Question: Part A: Find the GCF of 56 and 96. It is 8, already did this

Part B: Using the GCF you found in Part A, rewrite 56 + 96 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. Show your work.

Answer:

The correct answer is E.

Step-by-step explanation:

First I look for the relationships between the coefficients. The first term corresponds to the base value.

$\frac{8*d}{h^{2}} = \frac{8}{1} * \frac{d}{h^{2} }$

The second term corresponds to the value obtained when the density of the underlying material is doubled and the daily usage of the equipment is halved.

$\frac{2*8*d}{(0,5*h)^{2}} = \frac{16*d}{0,25 * h^{2}} = \frac{16}{0,25} * \frac{d}{h^{2} }$

With the I get the ratio of coefficients of $\frac{d}{h^{2}}$ :

$\frac{8}{1}$ = 8

$\frac{16}{0,25}$ = 64

Now I calculate the percentage increase in the useful life of the equipment as:

% = $\frac{64}{8}$ * %100 = %800

Which of the following are solutions to the graph

jarptica [38.1K]

Answer:

F. $\displaystyle (2, 6)$

C. $\displaystyle (-1, 0)$

B. $\displaystyle (-2, -2)$

Step-by-step explanation:

You first need to find the linear equation [in Slope-Intercept Form of course] of this graph, which is $\displaystyle y = 2x + 2.$ To do this, starting from the y-intercept of $\displaystyle (0, 2),$ you do $\displaystyle \frac{rise}{run}$ by either moving two blocks south over one block way or two blocks north over one block east [west and south are negatives]. This will give you your rate of change [slope] of 2.
