Answer:
Step-by-step explanation:
Since the lines are parallel to each other that means they have the same gradient. So use the gradient formula y=mx+c where m is the gradient rearrange 3x-2y=10 using the formula to become -2y=-3x +10
divide both sides by -2 so that m=1.5. It passed through the point (2,2) use the equation of a line formula to find the the answer.
[{y - 2}/{x -2}=1.5
cross multiply to get 1.5x-y=1

Answer:
k = -2
Step-by-step explanation:
The determinant can be formed by subtracting up-diagonal products from down-diagonal products:
(x)(x+y)(y) +(y)(x)(x+y) +(x+y)(y)(x) -(x+y)^3 -x^3 -y^3
= 3xy(x+y) -(x^3 +3x^2y +3xy^2 +y^3) -x^3 -y^3
= -2(x^3 +y^3)
The value of k is -2.

Answer: 4/5</h3>
Explanation:
We have 24 adults who passed and 16 teens who passed. So 24+16 = 40 people passed total.
There are 24+8+16+2 = 50 people total
If you pick someone at random, the probability of them passing is 40/50 = 4/5.
In decimal form, this is 4/5 = 0.80 which converts to 80%
Answer:
b < 16.5
