Answer:

Option C. x=7

Step-by-step explanation:

we know that

If PQ is parallel to BC

then

triangles APQ and ABC are similar

Remember that

If two figures are similar them the ratio of its corresponding sides is proportional

so

\frac{AP}{AB}=\frac{AQ}{AC}

substitute the values

\frac{x}{x+7+x}=\frac{x-3}{x-3+x+1}

Solve for x

\frac{x}{2x+7}=\frac{x-3}{2x-2}\\ \\x(2x-2)=(2x+7)(x-3)\\ \\2x^{2}-2x=2x^{2}-6x+7x-21\\ \\3x=21\\ \\x=7\ units

In this activity, you will create an equation for a function represented by a verbal description.
alexira [117]

Answer:

1) The initial value of the function is the y-value when the x-value is zero. The number of hours is the x-value and the percentage of battery life left is the y-value. When the number of hours, x, is 0, the percentage of remaining battery life, y, is 100 percent. So, the initial value of the function is 100. The initial value is positive because the percentage of remaining battery life cannot be negative.

2) The rate of change is the rate at which the y-value changes with respect to a change in the x-value. When off the charger, the phone loses its battery life at a constant rate of 5 percent per hour. So, the function’s rate of change is -5. The rate of change is negative because the rate indicates that the percentage of remaining battery life decreases as the number of hours increases.

A rectangular prism has a length of 5 meters, a width of 6 3/4 meters, and a height of 3 1/2 meters. What is the volume of the p
kirza4 [7]

Answer:

<h2>118.13 m³</h2>

Step-by-step explanation:

Given,

Length ( l ) = 5 meters

Width ( w ) = 6 \frac{3}{4} meters

Height ( h ) = 3  \frac{1}{2} meters

Now, Let's find the volume of rectangular prism :

volume \:  = l \:  \times  \: w \:  \times  \: h

plug the values

= 5 \times  \frac{27}{4}  \times  \frac{7}{2}

Calculate the product

= \frac{5 \times 27 \times 7}{4 \times 2}

=  \frac{945}{8}

= 118.13 \:  {m}^{2}

Hope this helps..

Best regards!!
