Answer:
x = -2
Step-by-step explanation:
Given f(x) = 3x – 1
f(x) = -7
3x-1 = -7
3x = -7+1
3x = -6
x = -2
Let x be the number of sheets Raj had before printing.
sheets per copy= 25/2 = 13(round up)
x = 10+ 13(22)
x = 296.
Raj had 296 sheets of paper before printing.
Answer:
283 or 382
Step-by-step explanation:
The number of children in 1st grade has 3 digits.The digit in the number are 2,3,and 8 .
Since the digit 8 means 80 in the number. The other two numbers could interchange the Hundred and Unit position respectively.
The possible numbers are:
I. 200+80+3=283
II. 300+80+2=382
The possible number of children in 1st Grade is either 283 or 382.
Y = 5x + 3.....the slope here is 5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, we flip the original slope and change the sign. So we have slope 5 or 5/1.....flip it and it becomes 1/5....change the sign and it becomes - 1/5. So our perpendicular line will have a slope of -1/5.
y = mx + b
slope(m) = -1/5
(2,2)....x = 2 and y = 2
now we sub into the formula and find b, the y int
2 = -1/5(2) + b
2 = -2/5 + b
2 + 2/5 = b
10/5 + 2/5 = b
12/5 = b
so ur perpendicular equation is : y = -1/5x + 12/5 <==
