Answer:
x = 5
Step-by-step explanation:
The ≅ sign means that both triangles are congruent, also meaning they're exactly the same. So with this in mind, the equations naturally equal each other:
3x + 3 = 5x - 7
Subtract 5x from both sides
-2x + 3 = -7
Subtract -3 from both sides
-2x = -10
divide by -2 to both sides
x = 5

Slope Is --3, and (1, 2) is on the line.
The equation of the line is y
Answers
Answer:
y= -3x + 5
Step-by-step explanation:
Use the equation of a line formula:
y- y1 = m(x - x1)
where y1 and x1 are the y and x coordinates from the given point (1,2)
So y1= 2
x1= 1
And where m is the slope, -3
Plug in to get y-2 = -3(x-1)
Simplify and solve for y
y= -3(x-1)+2
y= -3x +3 +2
y = -3x + 5

4 or 4/1 (both the same thing just with plotting point writing 4/1 is easier for me so I know to go up 4 over 1 :) )
Step-by-step explanation:
Parallel lines have the same slope, so both lines will have the same slope. Use line 1’s points to find the slope with the formula
(y1-y2)/(x1-x2)
(5-1)/(-2-(-3)
4/1=4

Caleb and Landon work at a dry cleaners ironing shirts. Caleb can iron 30 shirts per hour, and Landon can iron 15 shirts per hour. Caleb worked 2 more hours than Landon and they ironed 330 shirts between them. Write a system of equations that could be used to determine the number of hours Caleb worked and the number of hours Landon worked. Define the variables that you use to write the system
Answers
Answer:
The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked
Step-by-step explanation:
Assume that Caleb worked for x hours and Landon worked for y hours
∵ Caleb worked for x hours
∵ Landon worked for y hours
∵ Caleb worked 2 more hours than Landon
→ That means Caleb hours = Landon hours + 2
∴ x = y + 2
→ Subtract y from both sides
∴ x - y = 2 ⇒ (1)
∵ Caleb can iron 30 shirts per hour
∵ Landon can iron 15 shirts per hour
∵ They ironed 330 shirts between them
→ Multiply x by 30 and y by 15, then equate their sum by 330
∴ 30x + 15y = 330
→ Divide both sides by 15 to simplify the equation
∴ 2x + y = 22 ⇒ (2)
The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked

Answer: 2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x) [Work out the brackets]
15x-10=0+6+2x [Solve]
15x-10=16+2x [Convey the terms]
15x-2x=16+10 [Add up the same terms and calculate]
13x=26 [Divide both parts]
x=2
Answer:
x = 2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2.5(6x - 4) = 10 + 4(1.5 + 0.5x)
Step 2: Solve for x
Distribute: 15x - 10 = 10 + 6 + 2xCombine like terms: 15x - 10 = 16 + 2xSubtract 2x on both sides: 13x - 10 = 16Add 10 to both sides: 13x = 26Divide both sides by 13: x = 2Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 2.5(6(2) - 4) = 10 + 4(1.5 + 0.5(2))Multiply: 2.5(12 - 4) = 10 + 4(1.5 + 1)Subtract/Add: 2.5(8) = 10 + 4(2.5)Multiply: 20 = 10 + 10Add: 20 = 20Here we see that 20 does indeed equal 20.
∴ x = 2 is a solution of the equation.

The graph of the function y = 3(x - 2)^3 + 7 is translated 2 units to the
right and then 4 units down. Write the equation of the final graph.
Answers
Answer:
y = 3(x - 4)^3 + 3Step-by-step explanation:
Given function
y = 3(x - 2)^3 + 7Translation to the right achieved by adding - 2 to x-value
Translation down achieved by adding -4 to y-value
So the function becomes:
y = 3(x - 2 - 2)^3 + 7 - 4 ⇒y = 3(x - 4)^3 + 3Fun World charges $10.00 for admission plus $2.50 per hour to rent ice skates. IceLand charges $7.00
