Answer:
(a) 3x -5 =25
(b) x^2 + y = 18
(c) 6x/5 =4+x
(d) 1•5x + x =2(x-4)
Step-by-step explanation:
You have to add on to zeros to the number 2 and because there is a decimal point, that counts as a zero added. the stages:
2.2
22
220
your answer is 220 cm
Adam,
because for John if you add 6+6 = 12 for 20 dollars where Adam has 13 for 20
-x + 5y = 8....we need to put this in y = mx + b form to find the slope...the slope will be in the m position.
5y = x + 8
y = 1/5x + 8/5.....so the slope is 1/5...a perpendicular line will have a negative reciprocal slope. So the slope we need is -5.
y = mx + b
slope(m) = -5
(7,-1)..x = 7 and y = -1
now we sub and find b, the y int
-1 = -5(7) + b
-1 = -35 + b
-1 + 35 = b
34 = b
so ur perpendicular line is : y = -5x + 34
the original slope was 1/5...a parallel line will have the same slope
y = mx + b
slope(m) = 1/5
(7,-1)...x = 7 and y = -1
now we sub and find b, the y int
-1 = 1/5(7) + b
-1 = 7/5 + b
-1 - 7/5 = b
-5/5 - 7/5 = b
-12/5 = b
so ur parallel line is : y = 1/5x - 12/5
