on a number line, the directed line segment from q to s has endpoints q at –8 and s at 12. point r partitions the directed line

segment from q to s in a 4:1 ratio.which expression correctly uses the formula (startfraction m over m n endfraction) (x 2 minus x 1) x 1 to find the location of point r?

The location of the point R will be at R(x, y) =(\frac{-32}{5}, \frac{12}{5}  )

The midpoint formula is expressed according to the formula;

R(x, y) = (\frac{ax_1+bx_2}{a+b},\frac{ay_1+by_2}{a+b})

where;

  • a and b are the ratios

Given the coordinates Q(-8, 0) and S(12, 0) partitioned in a 4:1 ratio, the coordinate of point R will be expressed as:

R(x, y) = (\frac{4(-8)+0}{4+1},\frac{1(12)}{4+1})\\R(x, y) =(\frac{-32}{5}, \frac{12}{5}  )

Hence the location of the point R will be at R(x, y) =(\frac{-32}{5}, \frac{12}{5}  )

Step-by-step explanation:

We just subsitue 3 for x and -4 for y, so we get

3(3) - 5( - 4) = 9 + 20 = 29

So

a = 29

7(3) + ( - 4) = b

21 - 4 = 17

b = 17

Evaluate the expression. [(3–5)(34)]3 1 Innermost group, apply the product of powers: [3–1]3 2 Apply the power of a power: 3–3 3
Otrada [13]

Answer:

x=27

Step-by-step explanation:

To evaluate the expression: [(3^{-5})(3^4)]^3

Step 1:  Innermost group, apply the product of powers (a^x \times a^y =a^{x+y}

Therefore:

(3^{-5})(3^4)=3^{-5+4}=3^{-1}

We then have:

=[3^{-1}]^3

Step 2: Apply the power of a power

[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}

Step 3: Apply the negative exponent

3 ^{-3} =\dfrac{1}{3^3}

Step 4: Simplify

\dfrac{1}{3^3}=\dfrac{1}{27}

Therefore, the value of x in the simplified expression is 27.
