Put these into y=mx+b format SHOW YOUR WORK!!!! x-7y=7 and 6x-7y=-28
Answers
Explanation:
x - 7y = 7
-7y = -x + 7
y = (-1/-7)x + 7/-7
y = (1/7)x - 1
6x - 7y = -28
-7y = -6x - 28
y = (-6/-7)x - 28/-7
y = (6/7)x + 4
-x -x (isolate the y by subtracting x on both sides)
-7y= -x+7
— ——-
-7 -7 (Isolate the y by dividing both sides by -7)
Answer : y= 1/7x - 1
6x-7y= -28
-6x. -6x
-7y = -6x -28
—— ———-
-7. -7
Answer : y= 6/7x + 4

Answer:28
Step-by-step explanation: 6.4x6.4 = 40.96
3.6x3.6=12.96
Final answer:
To evaluate the expression (6.4)² - (3.6)², square each of the numbers and then subtract the square of 3.6 from the square of 6.4 to give a result of 28.
Explanation:
The question asked is mathematics related and it requires to evaluate an expression: (6.4)² - (3.6)². This is a simple arithmetic problem that involves squaring numbers and subtraction.
Firstly, squaring a number means multiplying the number by itself. Hence, (6.4)² equals to 6.4 * 6.4 which gives 40.96. Similarly, (3.6)² equals to 3.6 * 3.6 which gives 12.96.
Then, subtract the squared number of 3.6 from the squared number of 6.4. That is: 40.96 - 12.96, and you'll have your answer, which is 28.

Final answer:
The total cost for Jake to rent the pontoon boat for the entire three-day weekend, based on an estimated average hourly rate of $135, was $1330.
Explanation:
Firstly, we need to determine the hourly rate for the pontoon boat rental. We can use the information given for the Saturday and Sunday rentals to calculate this:
- Saturday: $435 for 3 hours, or $435 / 3 = $145 per hour
- Sunday: $625 for 5 hours, or $625 / 5 = $125 per hour
These two rates are different, so it's possible that a higher rate was charged for shorter rental times. To calculate the average, we add the two rates and divide by 2, giving us an average hourly rate of $135.
Finally, to calculate Jake's total cost for the weekend, we assume that the Monday rental also had the same $135 per hour rate, and multiply this rate by 2 hours. This gives us a Monday cost of $270. Adding this to the Saturday and Sunday costs, Jake's total cost for the three-day weekend was $435 + $625 + $270 = $1330.

Answer: $1400 for the total 3 days
Step-by-step explanation:
A= (3,435)
B= (5,625)
625-435 190
M= ————— = —— = 95
5-3 2
Y- 435= 95(x-3)
Y - 435= 95x - 285
Y= 95x + 150
95(2) + 150
190 + 150
= $340 for Monday
Finally,
435 + 625 + 340= $1400 for 3 days

Answer:
The value of 0 is 62
The expression of 0 is 0 = arcsin (cos (28))
Step-by-step explanation:
Sin(0) = cos(28)
The value of 0 is 90 - 28 = 62 degrees.
The expression of 0 is derived from algebraically solving for 0
0 = arcsin (cos (28))
