Answer:

21.3 repeating

Step-by-step explanation:

To solve for x, you need to do the inverse operation of multiplication.

So the inverse of multiplication is division.

So divide 3 by itself to isolate x, and whatever you do to one side you have to do to the other so:

3/3 = 1

64/3 = 21.3 repeating

x = 21.3 repeating

Answer:

$\frac{a^2}{b^2}$

Step-by-step explanation:

Apply the exponent rule $a^b*a^c=a^b+c$ to a

$a^4*a^-^2=a^4^-^2=a^2$

$b^3a^2b^-^5$

Apply the exponent rule to b

$b^3*b^-^5=b^3^-^5=b^-^2$

Apply the exponent rule $a^-^b=\frac{1}{a^b}$

$b^-^2=\frac{1}{b^2}=\frac{1}{b^2}a^2=\frac{a^2}{b^2}$

Answer:

$\lim_{x \to 10^+} h(x) = 18.5$

(5,12) with a slope m=10 the equation of the line is

motikmotik

Answer:

y= 10x-38

Step-by-step explanation:

Equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.

Given that m=10,

y= 10x +c

Now substitute the coordinates into the equation.

When y=12, x=5,

12= 10(5) +c

12= 50 +c

c= 12 -50

c= -38

Thus the equation of the line is y= 10x -38

David has zero fewer pears than Amy. Amy Has five pears. How many pears does david have?

Mariana [72]

He has ZERO fewer than Amy. That's actually another way of saying that he has the same amount as Amy.

since Amy has 5 pears, David also has 5 pears.
