Step-by-step explanation:
We are asked for any other pair [tex](x,y)[/tex] that suffices [tex]2y-3x = 5[/tex]. We can try [tex]x=1[/tex] (any other value also works because this is a line) and see that (4,2) suffices.
what is the equation of the following? Someone could help me to understand this? thank you
Answers
Answer:
y=(1/5)x
Step-by-step explanation:
First, we must find the slope of the line.
The slope of a line can be found using the formula: (y2-y1)/(x2-x1)
(3-0)/(15-0)
(3)/(15)
1/5
The slope is 1/5.
Next we find the y-intercept, or where the line crosses the y-axis. In this case, the y-intercept is 0.
This gives us the equation: y=(1/5)x

Answers
Answer:
x = 25
Step-by-step explanation:
For ∠ D and ∠ L to be congruent, then
3x - 8 = 2x + 17 ( subtract 2x from both sides )
x - 8 = 17 ( add 8 to both sides )
x = 25

many days does Torì need to spend making jam if she wants to jar 10 liters of jam in all?
Answers

Step by step: it’s asking you to find side BD, which is the adjacent to angle B.
And you know the opposite of angle B is AC or 3 inches.
This operation calls for TOA. T stands for Tan, OA stands for Opposite over Adjacent.
So we would do:
tan 60 = 3/x
And then next would be
x = 3/tan 60
Then, you probably have a calculator, so on a calculator do 3 divided by 60 and then press tan and press equal. You will get 1.73 which rounds to 1.7

The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of BB?
Answers
Answer:
(7, -4)
Step-by-step explanation:
The formula for calculating midpoint is expressed as;
M(X, Y) = (x2+x1)/2, (y1+y2)/2
X = x1+x2/2
Y = y1+y2/2
Given
X = 5, Y = 1, x1 = 3, y1 = 6
Get x2
X = x1+x2/2
5 = 3+x2/2
10 = 3+x2
x2 = 10-3
x2 = 7
Get y2;
Y = y1+y2/2
1 = 6+y2/2
2 = 6+y2
y2 = 2-6
y2 = -4
Hence the coordinate of B is at (7, -4)
