Answer:

$\left(\dfrac{3}{4}\right)^{14}$

Step-by-step explanation:

Given expression:

$\left(\left(\dfrac{3}{4}\right)^4 \times \left(\dfrac{3}{4}\right)^3\right)^2$

$\textsf{Apply the product rule of exponents} \quad a^b \cdot a^c=a^{b+c}:$

$\implies \left(\left(\dfrac{3}{4}\right)^{4+3}\right)^2$

$\implies \left(\left(\dfrac{3}{4}\right)^{7}\right)^2$

$\textsf{Apply the power of a power rule of exponents} \quad (a^b)^c=a^{bc}:$

$\implies \left(\dfrac{3}{4}\right)^{7\times 2}$

$\implies \left(\dfrac{3}{4}\right)^{14}$

Write the point-slope equation of the line that goes through (1, 4) with a slope of -10

sammy [17]

Answer:

y-4=-10(x-1)

Step-by-step explanation:

Point-slope form is:

$y-y_1=m(x-x_1)\\m-slope\\(x_1,y_1)-point$

We are given the slope of -10 and the point (1,4). So:

m = -10

x1 = 1

y1= 4

Replace the appropriate values:

$y-4=-10(x-1)$

So, y-4=-10(x-1) should be the point-slope equation.
