Hi there!

\large\boxed{-18a^{3}c^{3}}

To solve, keep in mind the following property:

xᵃ · xᵇ = xᵃ⁺ᵇ

We are given:

-3a⁷ (6)c⁷a⁻⁴c⁻⁴

Combine like exponent bases using the property above:

-3(6)a⁷⁻⁴c⁷⁻⁴

Simplify:

-18a³c³

Please help me with a geometry problem, I don't understand.
Goshia [24]

The slope-intercept form:

y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

m - slope

b - y-intercept

We have the points (1, -5) and (9, 11). Substitute:

m=\dfrac{11-(-5)}{9-1}=\dfrac{16}{8}=2

Therefore we have

y=2x+b

Put the coordinates of the point (1, -5) to the equation:

-5=2(1)+b\\\\-5=2+b\qquad\text{subtract 2 from both sides}\\\\-7=b\to b=-7

<h3>Answer: y = 2x - 7</h3>

Given sin z=4/5 and cos x=3/5. What is the ratio for tan z? Enter your answer in the boxes as a fraction in simplest form.
Minchanka [31]
The answer is:  "  \frac{4}{3} " .<span>
______________________________________________________
Explanation:
______________________________________________________
Note:  tan z = (sin z/ cos z) ;

           tan z = (4/5) / (3/5) ; 

                    = </span>\frac{4}{5} * \frac{5}{3} ; <span>
Note:  Both of the "5 ' s" cancel out to "1" ;  since:  "{5 ÷ 5 = 1 }" ;

And we rewrite as:

</span>→    " \frac{4}{1} * \frac{1}{3} "  ;

 =  \frac{(4*1)}{(1*3)} ;
<span>
 =  " </span>\frac{4}{3} " .

The answer is:  " </span> \frac{4}{3} " .

The sum of three consecutive odd number is one hundred fifty-nine. what is the smallest of the three numbers?
Black_prince [1.1K]
Let “n” represent the least of the odd numbers. Then the next two will be:
n + 2 and n + 4 that their sum is 159.

n + (n + 2) + (n + 4) = 159

3n + 6 = 159

3n = 153

n = 51

And to check: 51 + 53 + 55 = 159
