Answer:

Step-by-step explanation:

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)

m = 3

x₁ = -1

y₁ = -2

Therefore the equation:

y - (-2) = 3(x - (-1))

Answer:

Option B, $(48x^{8}y^{5})$

Step-by-step explanation:

<u>Step 1: Simplify the exponent</u>

$(12x^{2}y^{3})(2x^{3}y)^{2}$

$(12x^{2}y^{3})(2^{2}x^{3*2}y^{1*2})$

$(12x^{2}y^{3})(4x^{6}y^{2})$

<u>Step 2: Simply the expression</u>

$(12x^{2}y^{3}*4x^{6}y^{2})$

$(48x^{2+6}y^{3+2})$

$(48x^{8}y^{5})$

Answer: Option B, $(48x^{8}y^{5})$

I'm not sure how to simplify this expression with the exponents rules of multiplication

Vedmedyk [2.9K]

The rule of exponential multiplication is (a^x)*(a^y)=a^(x+y)
using this with your expression, we can do
(10^1)*(10^3)*(10^2)=10^(1+3+2)=10^6
Final answer:
10^6 or 1 million

Step-by-step explanation:

Step 1: Plot the points

L(1,2)

M(0,-1)

J(1,-2)

K(2,-1)

Step 2: Multiply each point by 5.

and record thise points so we have

L(5,10)

M(0,-5)

J(5,-10)

K(10,-5)

Step 3: Plot those points.

Naddik [55]

Answer:

Levi
Christopher
Roberto

Step-by-step explanation:

I like to work problems involving repetitive calculations using a spreadsheet. The sort function can easily put the results in the appropriate order.

Here, we need to compute minutes and kilometers remaining for each cyclist, and then divide the former by the latter to find the required timing.

Minutes remaining will be the difference between the qualifying time and the time used so far.

Km remaining will be the difference between the race length and the distance traveled so far.

Required minutes per km will be the ratio of minutes remaining to km remaining.

Levi has the least allowed minutes per km for his remaining distance. Roberto has the most.

_____

Christopher only has to increase his average speed by about 5% in order to qualify; Levi has the greatest challenge, as he needs about 18% more speed for the rest of the race.
