The solution using correct step of substitution in the equation y=2x-1 4x+y=2 is x = 1/2 and y = 0

<h3>Simultaneous equation</h3>

y = 2x - 1

4x + y = 2

  • Substitute the value of y in equation (1) into (2)

4x + y = 2

4x + (2x - 1) = 2

4x + 2x - 1 = 2

6x - 1 = 2

6x = 2 + 1

6x = 3

x = 3/6

x = 1/2

  • substitute the value of x into equation (1)

y = 2x - 1

y = 2(1/2) - 1

= 2/2 - 1

= 1 - 1

y = 0

Pretty sure that would be 120. Since the angles of a triangle add up to 180, you just add 25 and 35 (makes 60) and subtract it by 180, leaving 120

How to find slope and y intercept 6x-5y=15?
iogann1982 [59]
We need to put this equation in y = mx + b form because in this form, the slope will be in the m position and the y intercept will be in the b position. So basically, we solve for y.

6x - 5y = 15 ....subtract 6x from both sides
-5y = -6x + 15...divide both sides by -5
(-5/-5)y = (-6/-5)x + (15/-5)...simplify
y = 6/5x - 3

y = mx + b...remember, m is ur slope and b is ur y int
y = (6/5)x + (-3).....ur slope(m) = 6/5 and ur y int (b) = -3

Tuition at a community college increased from$55.00 to $62.00 per semester hour what is the % of increase..??
zlopas [31]
To find the percent of increase take the difference of the two divided by the original.  (62-55)/55 = .12727272727.  So 13% if they want you to round to the nearest percent.

What is the lcm for 7,14,16
MAXImum [283]

Answer:

112

Step-by-step explanation:

To find the least common multiple, we break the numbers down into prime factors

7 = 7

14 = 7*2

16 = 2*8 = 2*4*2 = 2*2*2*2

Then we take the largest number of times it appears in all the numbers

2 appears 4 times so we take take four 2's

7 appears 1 so we take one 7


LCM = 2*2*2*2*7

LCM = 112
