I just need help with this one question, im having trouble with it. Find an equation of the line that is perpendicular to the line shown below and passes through the point (-4,5). Show your work.
Answers
Answer:
[tex]y=\frac{-1}{2}x +3[/tex]
Step-by-step explanation:
Take any two points from the graph
(2 , 0) ; (0 , -4)
Slope = [tex]\frac{-4-0}{0-2}\\\\[/tex]
[tex]= \frac{-4}{-2}\\\\= 2[/tex]
Slope of the perpendicular line = -1/m = -1/2 = -1/2
m = -1/2 ; (-4 , 5)
y - y1 = m(x - x1)
[tex]y - 5 = \frac{-1}{2}(x -[-4] )\\\\y - 5= \frac{-1}{2}(x + 4)\\\\y - 5 = \frac{-1}{2}x +\frac{-1}{2}*4\\\\y-5 = \frac{-1}{2}x -2\\\\y = \frac{-1}{2}x-2+5\\\\y=\frac{-1}{2}x + 3[/tex]

8x+4 (4x+3) = 4 (6x+4)-4 help
Answers
Answer:
0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x+4(4x+3)=4(6x+4)−4
8x+(4)(4x)+(4)(3)=(4)(6x)+(4)(4)+−4(Distribute)
8x+16x+12=24x+16+−4
(8x+16x)+(12)=(24x)+(16+−4)(Combine Like Terms)
24x+12=24x+12
24x+12=24x+12
Step 2: Subtract 24x from both sides.
24x+12−24x=24x+12−24x
12=12
Step 3: Subtract 12 from both sides.
12−12=12−12

Answers
Answer:
17° and 73°
Step-by-step explanation:
For two complementary angles, the sum of angles is equal to 90 degrees.
Let other angle = x
First angle = 5+4x
ATQ,
5+4x+x=90
This is the equation that shows the given problems.
5+5x=90
5x = 85
x = 17°
Other angle = 17
First angle = 5+4x
= 5+4(17)
= 73°
So, the other two angles are 17° and 73° respectively.

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 of the same colour?
Answers
There are 6+5 marbles.
Of those, 5 are red.
The chances of drawing a red marble are 5/11
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time
5/11*5/11=25/121

Is either x = 9 or x = 15 a solution to x-3 = 12?
Answers
Answer:
Its 15 (x=15)
Step-by-step explanation:
I mean 15-3 is 12
Answer:
x = 15 is your solution.
Step-by-step explanation:
To find out what your answer is, plug in the given solutions for the variable, x, in the given equation:
When x = 9:
x - 3 = 12
(9) - 3 = 12
6 ≠ 12
When x = 15:
x - 3 = 12
(15) - 3 = 12
12 = 12

Numerele 10 si 5 seunt invers proportionale cu numerele 8 si b.Atunci b este:
Answers
Answer:
b should be 4.
Step-by-step explanation:
Put the numbers shown in the problem (10, 5, 8) and b into an equation.
10/5 = 8/b
Multiply both sides by b
10/5b = 8
2b = 8
b = 4
b should be 4 in this case.
In Romanian:
Puneți numerele prezentate în problemă (10, 5, 8) și b într-o ecuație.
10/5 = 8 / b
Înmulțiți ambele părți cu b
10 / 5b = 8
2b = 8
b = 4
b ar trebui să fie 4 în acest caz.
