Answer:
y+7 = -3 ( x-4)
Step-by-step explanation:
First find two points on the graph to find the slope
( 1,2) and ( 3,-4)
The slope is given by
m = ( y2-y1)/(x2-x1)
m = ( -4-2)/(3-1)
= -6/2
=-3
We can use the point slope form
y - y1 = m(x-x1) where m is the slope and x1,y1 is a point on the line
We have two choices with a slope of -3
We can either use and x coordinate of -2 or 4
for -2, the y coordinate is not shown
for 4 , the y coordinate is -7
Using ( 4, -7) and m = -3
y--7 = -3( x- 4)
y+7 = -3 ( x-4)
Answer:
A
Step-by-step explanation:
We want to write the equation of the line as shown in the graph.
First and foremost, we should find the slope of the line. To do so, we will pick two points that the line crosses.
We see that the line crosses the points (0, 5) and (2, -1). Now, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, 5) be (x₁, y₁) and let (2, -1) be (x₂, y₂). Substitute:
[tex]m=\frac{-1-5}{2-0}[/tex]
Subtract and reduce. So, our slope is:
[tex]m=-6/2=-3[/tex]
Therefore, our slope is -3.
Now, we can use the point-slope form to find the equation. Point-slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is any point the line crosses.
First, since we already know that our slope is -3, let's substitute -3 for m:
[tex]y-y_1=-3(x-x_1)[/tex]
So, we can eliminate choices C and D since the slope of those equations is 3 and not -3.
Now, we need to pick our (x₁, y₁). Let's go through the answer choices A and B to see which one is correct.
For A, we have:
[tex]y+7=-3(x-4)[/tex]
We can rewrite this as:
[tex]y-(-7)=-3(x-(4))[/tex]
Therefore, in A, our point is (4, -7).
Now, check. Does our line actually pass through (4, -7).
From the graph, we can see that it does. Therefore, A is our correct answer!
However, let's do B just to confirm. For B, we have:
[tex]y+1=-3(x+2)[/tex]
We can rewrite this as:
[tex]y-(-1)=-3(x-(-2))[/tex]
So, our point is (-2, -1).
Does our line pass through (-2, -1)?
Upon inspection, our line does not pass through (-2, -1). So, B is not correct.
So, our answer is A.
And we're done!

Solve this equation
100x + 300 = 200
Answers
Answer:
-1
Step-by-step explanation:
100x=200-300
100x=-100
100x/100=-100/100
x=-1
After solving this equation we get, 100x + 300 = 200 x = -1.
To solve this equation
100x + 300 = 200,
Subtract 300 on both side,
100x + 300 - 300 = 200 - 300
100x = -100
Divide 100 on both side,
x = -1
Therefore, After solving this equation 100x + 300 = 200 we get x = -1.

Answer:
the answer is c
Step-by-step explanation:
Becuase he is given 100 dollars and he uses 20 dollars a day, so you put x with 20 to calculate how many days that he can spend $20 on
Day 1: money spent = 20
Day 2: total money spent = 20+20 = 2*20
So, for x days, total spent money should be 20*x = 20x
At an instant, say, after x days.
=> saving = total amount - spent
=> money left = 100 - 20x
=> y = 100 - 2x
=> y = - 2x + 100

Answers
Answer:
45º, 45º, 90º
Step-by-step explanation:
Assume angles are x then third is x+x = 2x.
sum of angles in a triangle = 180

=> 4x = 180
=> x = 180/4 = 45
so, angles are 45,45 and 90.
