(3-2i)(-10-7i)

-30+20i-21i+14i^2 where i^2=-1

-30-i+14(-1)

-30-i-14

-30-14-i

-44-i

Answer:

$(3 - 2i)( - 10 - 7i) \\ = - 30 - 21i + 20i + 14 {i}^{2} \\ = - 30 - i - 14 \\ = - 44 - i$

I hope I helped you^_^

Simplify the expression.<br>Write your answer without negative exponents. NEED AN ANSWER ASAP

harina [27]

Answer:

$\boxed{\frac{-3b^4 }{a^6 }}$

Step-by-step explanation:

$\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}$

$\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

$-3 \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

$-3 \times a^{-8-(-2)} \times b^{-3- (-7)}$

$-3 \times a^{-8+2} \times b^{-3+7}$

$-3 \times a^{-6} \times b^{4}$

${-3a^{-6}b^{4}}$

The answer should be without negative exponents.

$a^{-6}=\frac{1}{a^6 }$

$\frac{-3b^4 }{a^6 }$

Write an equation in point-slope form for the line with a slope of -9 that passes through (-1,-3)

Elena L [17]

Answer:

$y+3=-9(x+1)$

Step-by-step explanation:

The formula for point slope is: $y-y1=m(x-x1)$

When:

m = slope

(x1,y1) = the point on the graph

-9 is the slope, so it replaces m. x1 is -1, and y1 is -3.

Plug in the values:

$y-(-3)=-9(x-(-1))$ OR $y+3=-9(x+1)$

Balu and Pumba shared ½ of a cake. Balu got to eat twice as much cake as Pumba. What fraction of the whole cake did Balu eat?

Ghella [55]

Okay. So, basically a 1/2 of a cake would be broken into 3 parts, because Balu eats double the amount Pumba does and Pumba eats cake as well. Let’s do 1/2 / 3. To divide fractions, keep 1/2 the same, change the division into multiplication, and flip 3 into 1/3. Multiply across. 1/2 * 1/3 is 1/6. 1/6 * 2 is 2/6. 2/6 is twice of 1/6 and 1/6 + 2/6 = 3/6. 2/6 in simplest form is 1/3. Balu ate 1/3 of a whole cake.
