Answer:

Answer:

y = -5x + 6

Step-by-step explanation:

y = 1/5 x + 4/5

so that two lines are perpendicular, its slope must be opposite and reciprocal

y = m x + b

m: slope perpendicular -1/m

if our formula is y = 1/5 x + 4/5

m = 1/5

so the slope of our new formula will be

m' = -5/1

m' = -5

now if you tell us that you have to go through a certain point (1/1)

we just have to replace the values in the following formula and solve

y - y1 = m ( x - x1)

y - 1 = -5 ( x - 1)

y = -5x + 5 + 1

y = -5x + 6

What is the correct order of operations for simplifying the expression (x+3)^2-(x^2+9)/2x^2

Answers

Answer with explanation:

The correct order of simplifying the expression is:

1. Opening the bracket Using Identity

2. Adding and Subtracting Like terms

The given expression is

$=((x+3)^2-(x^2+9))/(2x^2)\n\n=(x^2+6 x+9-x^2-9)/(2x^2)\n\n=(6x)/(2x^2)\n\n=(3)/(x)\n\n \text{Used the identity and law of indices}\n\n(a+b)^2=a^2+2 a b+b^2\n\n (x^a)/(x^b)=x^(a-b)$

$((x+3)^2-(x^2+9))/(2x^2)\n\nuse\ (a+b)^2=a^2+2ab+b^2\n\n=(x^2+2\cdot x\cdot3+3^2-x^2-9)/(2x^2)=(x^2-x^2+6x+9-9)/(2x^2)\n\n=(6x)/(2x^2)=(3)/(x)$

In a bag of marbles, you have 4 green, 3 yellow, 5 blue, and 8 red marbles. What is the probability of picking a green marble from the bag?a) 3/20
b) 1/5
c) 1/10
d) 1/4

Answers

4 + 3 + 5 + 8 = 20

4 / 20 = 1/5

A) 3/20
add up all of the marbles and whatever is asking you for possibilities is the number of marbles is given you already. for example. i have a ticket for a raffle. so i got only 1 and there is 25 people more with a ticket. what are my chances of winning? 1 out of 25 right?(1/25) because i got 1 ticket if i had 2 it would be 2 out of 25 or (2/25) hope this helps. :)

Solve the equation. Check for extraneous solutions.

Answers

assume
if |a|=b
a=b and -a=b

so

9|9-8x|=2x+3
divide both sides by 9
|9-8x|=2/9x+1/3
assume
9-8x=2/9x+1/3 and
-9+8x=2/9x+1/3

9-8x=2/9x+1/3
times 9 both sides
81-72x=2x+3
add 72x both sides
81=74x+3
minus 3
78=74x
divide both sides by 74
39/37=x

other one
-9+8x=2/9x+1/3
multiply both sides by 9
-81+72x=2x+3
minus 2x both sides
-81+70x=3
add 81 to both sides
70x=84
divide boh sides by 70
x=6/5

x=39/37 and 6/5
check

9|9-8(39/37)|=2(39/37)+3
2646/37=189/37
false

9|9-8(6/5)|=2(6/5)+3
351/5=27/5
false

A segment has endpoints A (-1, 1) and B (8, 4) . If the segment is divided into four equal parts, the coordinates of the point closest to point A are _____. (7/2, 5/2) (5/4, 7/4) (23/4, 13/4)

Answers

Line is divided into 4 equal parts.

we have to find a point which is closest to point A.

So that means required point P(x,y) is at 1 unit away from A(-1,1) and 3 unit away from B(8,4)

Now we just need to use section formula to get the coordinate of required point using m1=1 and m2=3

$\left ( (m_1x_2+m_2x_1)/(m_1+m_2) , (m_1y_2+m_2y_1)/(m_1+m_2) \right )$

$= \left ( (1*8+3*(-1))/(1+3) , (1*4+3*1)/(1+3) \right )$

$= \left ( (8-3)/(4) , (4+3)/(4) \right )$

$= \left ( (5)/(4) , (7)/(4) \right )$

So the final answer is $\left ( (5)/(4) , (7)/(4) \right )$ .
