Solve each system of equations using substitution. x×y=5 4+y=-x

valina [46]

Answer:

Step-by-step explanation:

$\left \{ {{xy=5} \atop {4+y=-x}} \right.\\\\ \left \{ {{xy=5} \atop {x=-4-y}} \right.\\\\=> \left \{ {{(-4-y)y=5} \atop {x=-4-y}} \right. \\\\ \left \{ {{-y^{2}-4y =5} \atop {x=-4-y}} \right. \\\\ \left \{ {{y^{2}+4y+5 =0} \atop {x=-4-y}} \right.$

because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R

=> y² + 4y + 5 = 0 is unreasonable

=> no solutions

What is the area of the figure:

Luba_88 [7]

For this case we have that the area of the triangle is given by:

$A = \frac {b * h} {2}$

Where:

b: It's the base

h: It's the height

We have to:

$cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}$

The atura will be given by:

$sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}$

So, the area is:

$A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144$

Answer:

144

What is the rate of change of the function shown on the graph? Round to the nearest tenth.

faltersainse [42]

<u>Answer</u>:

The required is the multiplicative rate of change.

The correct answer is the second option<u> 2.5</u>

<u>Step-by-step explanation:</u>

The given function has the form of the exponential function

The general equation of the exponential function $y=c * r^x$

Wher c is constant and r is the multiplicative rate of change.

Using the given points to get the values of c and r

By using the point (0,2) ⇒∴ $2=c * r^0$ ⇒ c = 2

By using the point (1,5) ⇒∴ $5=2 * r^1$ ⇒ r = 5/2 = 2.5

Check the answer using the other points

If x = 2 ⇒⇒⇒ $y=2 * 2.5^2 = 12.5$

If x = -1 ⇒⇒⇒ y=2 * 2.5^(-1) = 0.8

<u>So, the multiplicative rate of change = 2.5</u>
