A line passes through the points (1,-6) and (4,3) What is the Y intercept of this line?
Answers
Answer: b=-9
Step-by-step explanation:
To find the y-intercept of the line, we can use the points given to make an equation. To find the slope, you use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{3-(-6)}{4-1} =\frac{9}{3} =3[/tex]
Now that we know the slope, we can fill in what we know and solve for y-intercept.
y=3x+b
We can plug in any point to solve for y-intercept.
3=3(4)+b [multiply]
3=12+b [subtract both sides by 12]
b=-9
Now, we know that the y-intercept is b=-9.

Answers
Answer:
26°
Step-by-step explanation:
The angle 5 is equal to angle 154° as these are both corresponding angles and corresponding angles are equal.
Angles on a straight line equal 180°, so if we take 154° from 180° we get angle 4, which is 26°
I hope that helped!
XY and WZ are parallel.
Angle 1 + 154° = 180° (Linear pair)
→ Angle 1 = 180 - 154
→ Angle 1 = 26°
Now, Angle 4 = Angle 1 (Alternative interior angles)
→ Angle 4 = 26°
Hence, we got the answer.

B. Not enough information
C. x = 10
D. x = 4
Answers
x= -10
Explanation:
When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.

Answers
Select the correct answer from each drop-down menu.
cos2x-cos4x/sin2x+sin4x = tan x
cos2x+cos4x/sin2x-sin4x = -cot x
The trigonometric equations have value tan x, -cot x .
What is a Trigonometric Ratios?Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.
The trigonometric equation is
(cos 2x - cos 4x )/(sin2x +sin4x)
cos A + cos B = - sin (A+B)/2 sin(A-B)/2
sin A - sin B = sin( A+B)/2 cos (A-B)/2
= (-sin 3x) sin ( -2x)/2)/( cos 3x cosx)
= sin 3x sin x/ (sin 3x) cos x
= tan x
The other equation is
(cos 2x +cos 4x)/(sin 2x- sin4x)
= cos 3x cosx/ cos3x sin(- x)
= - cot x

Use the given endpoint Y and the midpoint M of YZ (there is a line over YZ) to find the coordinates of the other endpoint Z
Answers
The x-coordinate of our midpoint = 3
The x-coordinate of Y = 0
k = x-coordinate of Z
3 = (0 + k) / 2
Multiply both sides by 2
6 = k + 0
Simplify
6 = k
The y-coordinate of our midpoint = 3
the y-coordinate of Y = 5
w = y-coordinate of Z
3 = (w + 5) / 2
Multiply both sides by 2
6 = w + 5
Subtract 5 from both sides
1 = w
For problem #17, Z(6, 1)
Let's do problem 18 now.
The x-coordinate of our midpoint = 5
The x-coordinate of Y = -1
k = x-coordinate of Z
5 = (k + (-1)) / 2
Multiply both sides by 2
10 = k + (-1)
Simplify the right side
10 = k - 1
Add 1 to both sides
11 = k
The y-coordinate of our midpoint = 9
The y-coordinate of Y = -3
w = y-coordinate of Z
9 = (w + (-3)) / 2
Multiply both sides by 2
18 = w + (-3)
Simplify the right side
18 = w - 3
Add 3 to both sides
21 = w
For problem #18, Z(11, 21)

Answers
Answer:
C. 30
Step-by-step explanation:
Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.
3•7 = 21=x --> A prime = (21,28)
4•7 = 28=y
[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]

Answers
Answer:
Step-by-step explanation:
y=3x-14
standard form : 3x-y=14 ( move variable together on one side )convert y-6=-1/3 (x-9) to standard form :
first : y-6 = -1/3 x -1/3(-9)
y-6=-1/3 x +9/3
y-6=-1/3x+3
y+1/3x =3+6
y+1/3x=9 ( common denominator)
(3y+x)/3=9 ( cross multiplication)
3y+x=3(9)
3y+x=27Convert 3x+y=9 (standard form) to slope intercept form (y=mx+b)

Becky leaves school to go home. She walks 6 blocks North and then 8
blocks west. How far is Becky from the school?
Answers
Answer:
10 blocks
Step-by-step explanation:
The distance of Becky from the school is 10 blocks.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
We have been given that Becky leaves school to go home. She walks 6 blocks North and then 8 blocks west.
According to the given situation, we can plot the diagram which has been attached below.
As per the figure, we have a right triangle that has :
AB = 8 blocks, and BC = 6 blocks
The distance of Becky from the school is equal to the length of AC.
By Pythagoras's theorem,
AC² = AB² + BC²
AC² = 8² + 6²
AC² = 64 + 36
AC² = 100
AC = 10 blocks
Therefore, the distance of Becky from the school is 10 blocks.
