Write an expression equivalent to h^6/h^3 in the form of h^m

Pavel [41]

Answer:

$h^3 = h^m$

Step-by-step explanation:

$\frac{h^6}{h^3} = h^m$

6 - 3 = 3

keep the base same, therefore

$h^3 = h^m$

Given the following formula, with A = 27 and t = 3, solve for r. <br> A=p(1+rt)

Nookie1986 [14]

Answer:

<h2>A. $r=\frac{27-p}{3p}$ </h2>

Step-by-step explanation:

The given formula is

$A=p(1+rt)$

Where $A=27$ and $t=3$

To solve for $r$ , first we need to move $p$

$\frac{A}{p}=1+rt$

Then, we move the term 1

$\frac{A}{p}-1=rt$

Finally, we move the factor $t$

$\frac{\frac{A}{p}-1 }{t} =r$

Replacing given values, we have

$\frac{\frac{27}{p}-1 }{3} =r\\r=\frac{\frac{27-p}{p} }{3} \\r=\frac{27-p}{3p}$

Thereofre, the right answer is A.

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?

Helen [10]

Answer:

$y=7x+1$

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$m=7$

$point(1,8)$

substitute and solve for b

$8=7(1)+b$

$8=7+b$

$b=8-7=1$

The equation of the line is equal to

$y=7x+1$
