Answer:
x=8 and y=23
Step-by-step explanation:
Rewrite equations:
y=2x+7;y=3x−1
Step: Solve y=2x+7 for y:
y=2x+7
Step: Substitute 2x+7 for y in y=3x−1:
y=3x−1
2x+7=3x−1
2x+7+−3x=3x−1+−3x(Add -3x to both sides)
−x+7=−1
−x+7+−7=−1+−7(Add -7 to both sides)
−x=−8−x−1=−8−1
(Divide both sides by -1)
x=8
Step: Substitute 8 for x in y=2x+7:
y=2x+7
y=(2)(8)+7
y=23(Simplify both sides of the equation)

how can i solve this
tan2x/(tan4x-tan2x)
Answer: = cos 4x
[tex]\frac{tan2x}{tan4x-tan2x}\\\\=\frac{tan2x}{\frac{2tan2x}{1-tan^{2}2x }-tan2x }\\\\=\frac{tan2x(1-tan^{2}2x) }{2tan2x-tan2x(1-tan^{2}2x) }\\\\=\frac{tan2x(1-tan^{2}2x) }{tan2x(2-1+tan^{2}2x) }\\\\=\frac{1-tan^{2}2x }{1+tan^{2}2x } \\\\=\frac{1-\frac{sin^{2}2x }{cos^{2}2x } }{1+\frac{sin^{2}2x }{cos^{2}2x } }\\\\=\frac{cos^{2}2x-sin^{2}2x }{cos^{2}2x+sin^{2}2x } \\\\=\frac{cos4x}{1}\\\\=cos4x[/tex]

Recall that the center of dilation is point J. On the logo, identify one or two line segments: that contain the center of dilation that do not contain the center of dilation that lie on a line that passes through the center of dilation Record the names of the line segments you identified and the category they belong to. What differences do you notice in the way these categories of line segments are mapped from the preimage to the image?
PLATO
Answer:
HA , LJ , and IK contain the center of dilation. Line segments that contain the center of dilation in the preimage also contain the center of dilation in the image. GF , HI , and KL do not contain the center of dilation. Line segments that do not contain the center of dilation in the pre image are mapped onto distinct lines parallel to the original, corresponding line segment. HL does not contain the center of dilation either but it does lie on a line that passes through the center of dilation. Line segments that lie on lines passing through the center of dilation in the preimage lie on the same lines in the image.

Answer:{ x,y } = { - 2, - 3 }
Step-by-step explanation: 4x = 2y - 2
x = y/2 - 1/2
3. (y /2 - 1/2 ) + 2y = - 12
7y/2 = - 21/2
7y = - 21
x = y/2 - 1/2
y = - 3
x = (/2) ( - 3 ) - 1/2 = - 2
The system of equations is graphed on the coordinate plane.
y=-5/3x+3
y=1/3x - 3
Enter the coordinates of the solution to the system of equations
in the boxes.
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.

1
Answer:
-1
Step-by-step explanation:
-5x – 15 > 10 + 20x
-5x -20x > 10+15
-25x > 25
x < -1
Eve won a bag full of money! She has 49 bills in all. She counts $1430. There are twenty dollar bills and fifty dollar bills. How many of each bill does Caitlin have?
Answer: (Just type the number.)
Number of $20 bills:
Number of $50 bills:
Number of $20 bills: 34
Number of $50 bills: 15
The equations are
x + y = 49
20x + 50y = 1430

You find the intersection point of the two lines, which is (3, -2).
It is what the question meant when it asked for "solution".
These two lines are y = mx + c, which is another form of linear equations with two variables you are likely familiar with
x+y=20
x-y=10

Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.
The area of the circle will be 3.14 feet .
Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.
Answer:-★Given,
→ Diameter = 2 feet
→ Circumference = 2/2 = 1 feet
★Now,
→Area of a circle = πr²
→ = 3.14 × 1 × 1
→ = 3.14 feet
Hence , the circumference is 3.14 feet.
