Answer:

The area of triangle VZX is 210 cm^2

Step-by-step explanation:

Here, we want to get the measure of the area of triangle VZX

From the given diagram, we have two explicit triangles making up triangle VWX

These are triangles VWZ and VZX

By adding the areas of both triangles, we can get the area of VWX

Mathematically, the area of VZX is the difference between the area of VWX and VZW

To get the area of VZW, we can use the formula for the area of a triangle

We have this as 1/2 * base * height

base = 35 cm and height = 28 cm

The area of VWZ is 1/2 * 35 * 28 = 490 cm^2

The area of triangle VZX is thus;

700 cm^2 - 490 cm^2 = 210 cm^2

5x−2.5+6x−3= ___ (2x−1)<br><br><br> someone help me with this q.<br><br> will mark brainliest~
cestrela7 [59]

Answer:

5.5

Step-by-step explanation:

So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.

So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.

  • Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5
  • Now we have 11-5.5=?
  • so, we need to have (2x-1) in our answer because the problem asks for that in the answer.
  • We need to find a number that satisfies the equation and answer
  • so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.
  • 5.5 satisfies the equation, therefore is the answer

The function f(x)=1200(0.8)^x represent the possible elk population of a national park x years from now. What is the current pop
sukhopar [10]

If <em>x</em> is the number of years from now, that means the <em>current</em> population is when x=0


Therefore, we plug this into the equation:

f(x) = 1200(0.8)^0 = 1200 elk at the park currently

A car is discounted 10% and sells for $15,673. What was the discount amount?
Mice21 [21]

Answer:

  $1741.44

Step-by-step explanation:

The discounted amount is 100% -10% = 90% of the original. The amount of the discount is 10% of the original, or 1/9 of the discounted amount:

  10% = 90% × 1/9

The discount was ...

  $15,673/9 = 1,741.44

_____

<em>Check</em>

The original is the sum of the discounted amount and the discount:

  original price = $15,673.00 +1,741.44 = $17, 414.44

10% of that value is 1,741.44, as shown above.

X-4y=-17 and y=4x +8 solve by graphing please and show the solution
nikitadnepr [17]

Answer:

The answer to your question is (-1, 4) The lines cross in one point so they have only one solution.

Step-by-step explanation:

Data

Equation 1     x - 4y = -17

Equation 2    y = 4x + 8

Solve for y

Equation 1          y = -x/-4 - 17/-4

                          y = x/4 + 17/4

Equation 2         y = 4x + 8

See the graph below

These lines cross in point (-1, 4), so that is the only one solution.

If the lines were the same line they would have infinite solutions
