As your -2 is directly affecting the x with addition/subtraction, it is a translation horizontally. To find direction, change the sign, from negative to positive, making it go right. This means it will be translated 2 units to the right, fitting the first statement. For your +5, it is not directly affecting the x, making it a translation vertically. As it's positive, it goes up, making it a translation 5 units up, fitting statement 4. This makes your correct statements 1 and 4.
Answer:
2x + 2y
Step-by-step explanation:
10x + 5y - ( 3x + 4y + 5x - y )
10x + 5y - 3x - 4y - 5x + y)
2x + 2y
Answer:
<u>k = 5; y = 5x</u>
Step-by-step explanation:
The constant of proportionality is the value of y/x. Picking a random value on the graph, such as (2, 10), we can substitute this into the formula for k = y/x. 10/2 = 5. This satisfies one portion of the answer. Now, if we take the value of x from the same point, (2, 10), which is 2, and multiply it by 5, as illustrated in y = 5x, we get 10 for y. This suits the equation as mentioned and we can check other points with the same process to ensure that this answer is correct.
Jeremy's weekend work would follow the equation of the standard line. The equation of the standard line is y=mx+b. b= 0, The slope of the line is equal to m, where m according to the given problem is equal to 35. Every hour of Jeremy weekend would pay $35.
Jeremy's equation
y= 35x
m=35
Answer:
262
Step-by-step explanation:
3(90) - 8 = x
270-8 = x
262 = x
