The linear combination method is applied to a system of equations as shown.4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
What is the solution of the system of equations?

(1,2)
(3,9)
(5,5)
(9,3)

Answers

Answer 1

Answer: 2x = 18
x = 18/2
x = 9

4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3

- 2y = 3 - x
- 2y = 3 - 9
- 2y = - 6
y = - 6/ - 2
y = 3

Wren recorded an outside temperature of –2°F at 8 a.m. When she checked the temperature again, it was 4°F at 12:00 p.m. If x represents the time and y represents the temperature in degrees Fahrenheit, what is the slope of the line through these two data points?a.–1.5

b.–0.5

c.0.5

d.1.5

Answers

Let consider time on x-axis and temperature ony-axis.

The x-axis starts from “0” corresponds to “8 a.m”.Thus after 4 hours, the time will be “12pm”. So we have two values on x-axis,one is “0” and another “4”.

For x = 0, or time value = 8am, the temperature value= y-axis value = -2

For x = 4, or time value = 12pm, the temperaturevalue = y-axis value = 4

Thus we got two points (0,-2) and (4,4).

Now using slope formula = (y2 –y1) / (x2 –x1)

Slope = (4-(-2)) / (4 -0) = 6/4 = 1.5
