Answer:

Step-by-step explanation:

The temperature must not be greater than 15 which means 15 is the maximum. It's not saying it can't reach 15, it's saying it can't go past it.

So it wouldn't be t < 15. It would be t is less than or equal to 15

Answer: The number can be used to express the change in temperature= -14

Step-by-step explanation:

Given: The temperature in evening dropped by $14^{\circ}F$ .

Thus, the change in temperature = $14^{\circ}F$

Since the temperature in evening is dropped or decreased , thus in integers the change in temperature = $-14^{\circ}F$

Therefore, the number can be used to express the change in temperature= -14

The function f(x)=x−−√ is reflected over the x-axis, translated 4 units down and 5 units to the left, then vertically stretched

Gnesinka [82]

Transformation involves changing the position of a function.

The equation of the new function is: $\mathbf{g(x) = -3\sqrt{x + 5} - 12}$

The function is given as:

$\mathbf{f(x) = \sqrt x}$

The rule of reflection across the x-axis is:

$\mathbf{(x,y) \to (x,-y)}$

So, we have:

$\mathbf{f'(x) = -\sqrt x}$

The rule of translation, <em>4 units down and 5 units left </em>is:

$\mathbf{(x,y) \to ( x + 5,y-4)}$

So, we have:

$\mathbf{f"(x) = -\sqrt{x + 5} - 4}$

The rule of vertical stretch by a factor of # is:

$\mathbf{(x,y) \to (x,3y)}$

So, we have:

$\mathbf{g(x) = 3(-\sqrt{x + 5} - 4)}$

$\mathbf{g(x) = -3\sqrt{x + 5} - 12}$

Hence, the equation of the new function is:

$\mathbf{g(x) = -3\sqrt{x + 5} - 12}$

Can someone please help?

Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.

now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,

$\bf y=-\cfrac{2}{3}x+7\implies \boxed{3}\cdot y=\boxed{3}\cdot \left( -\cfrac{2}{3}x+7 \right)\implies 3y=-2x+21
\\\\\\
\stackrel{standard~form}{2x+3y=21}$
