If it’s a negative minus a negative, like the problem you gave, Y- -5, that will turn into y+5. Because a negative minus a negative turns into a positive

Can anyone do this please

morpeh [17]

Answer:

I know for the fact that it's the first one but I don't know the other answer

Step-by-step explanation:

An equation of a graph is y=mx+b and the B is the y-intercept which is -2 since the line is on top of -2. mx is the rise/run of -2 which is -3/2

Hope this helps, but I don't which other equation represents the graph.

Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can

Firdavs [7]

Answer:

18.75 ft

Step-by-step explanation:

The given scenario can be drawn as shown in the following attachment.

Given that,

$m\angle DCE=\angle ACB$ and $m\angle DEC=\angle ABC=90^{\circ}$

Therefore, $\Delta ABC\sim \Delta DEC$

$\Rightarrow \dfrac{AB}{DE}=\dfrac{BC}{EC}$

$\Rightarrow \dfrac{AB}{5}=\dfrac{15}{4}$

$\Rightarrow AB=\dfrac{15\times 5}{4}=18.75$ ft

AB is the height of the house.

The difference of the square of a number and 28 is equal to 3 times that number find the positive solution

lutik1710 [3]

<h2>The required positive number is 7.</h2>

Step-by-step explanation:

Let the number = x

To find, the positive number = ?

According to question,

$x^{2}-28=3x$

⇒ $x^{2}$ - 3x - 28 = 0

By Factorisation method,

⇒ $x^{2}$ - 7x + 4x - 28 = 0

⇒ x(x - 7) + 4(x - 7) = 0

⇒ (x - 7)(x + 4) = 0

⇒ x - 7 = 0 or, x + 4 = 0

⇒ x = 7 or, x = - 4 [ - 4 is a negative number)

⇒ x = 7

Thus, the required positive number is 7.

The average rate of change of f from 2 to 3

ella [17]

For a function of $f$ , the average rate of change can be found as follows:

$ARC=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}$

So, this problem asks for the Average Rate of Change of $f$ from $x_{1}=2$ to $x_{2}=3$ . In this way, we need to find $f(x_{1}) \ and \ f(x_{2})$ . As you can see above, we have the graph of $f(x)$ , so we can find these values. Thus, from the graph:

$f(x_{1})=4 \\ f(x_{2})=1$

Therefore:

$ARC=\frac{1-4}{3-2} \\ \\ \therefore \boxed{ARC=-3}$
