Hello,

|x+4|=3x-5
if x+4>=0 then
          |x+4|=x+4
          x+4=3x-5
          2x=9
            x=9/2
else
    x+4<0 : x<-4
    |x+4|=-(x+4)
     -(x+4)=3x-5
    -x-4=3x-5
    4x=1
    x=1/4 : to exclude since x<-4
end if

Only one solution : x=9/2
ANSWER B.

The original purchase price of a car is $25,000. Each year, its value

White raven [17]

<h3>Answer:</h3>

$16,462.58 (rounded from $16462.575)

<h3>Explanation:</h3>

By subtracting 13%, you leave 87%, because $100-13=87$ .

So, the expression we need to simplify is $25000 * 0.87^3$ , because you need to multiply 25000 by 87% three times.

Find the exponent with a calculator. $25000 * 0.658503$
Multiply with a calculator. $16462.575$
Round your answer to the nearest cent. $16462.58$

If f(x) is a linear function, what is the value of n?

bulgar [2K]

Answer:

Step-by-step explanation:

Take any two corresponding values, say (3,7) and (9,16)

Calculate the gradient of the linear function

Gradient=[16-7]/[9-3]=9/6=3/2

find the equation or rule of the linear mapping

y-7=(3/2)(x-3)

y=3x-9+7

y=(3/2)x+5/2

Suppose you have one pyramid with a base that is 10 meters long and 10 meters wide with a slant that is 15 meters. Now, if the l

marishachu [46]

Answer:

The difference between area of pyramids is 125 sq.m.

Step-by-step explanation:

Length of base = 10m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = $\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10$

Area of pyramid = 400 sq.m.

Now the length of base is increased to 15

Length of base = 15m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = $\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10$

Area of new pyramid = 525 sq.m.

Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.

Hence The difference between area of pyramids is 125 sq.m.
