Answer:(15x +14)
Step-by-step explanation:
Am assuming the text of the problem is:
"At 6:00 p.m., the temperature was 55 Fahrenheit. At 11:00 p.m. that same evening, the temperature was 40 Fahrenheit. What real number represents the average change in temperature per hour?"
Average change in temperature per hour = (55 - 40)/(11 - 6)
Average change in temperature per hour = 15/5
Average change in temperature per hour = 3 Fahrenheit per hour
Answer:
(5x - 1)(2y - 3)
Step-by-step explanation:
10xy - 15x - 2y + 3 = 5x (2y - 3) - (2y - 3) = (5x - 1) (2y - 3)
Sequence: 1,7,49,343,??,16807, 7th term, 8th....
we notice that:
1st term = 1 or 7^0
2nd term = 7 or 7^1
3rd term =49 or 7^2
4th term = 343 or 7^3
5th term = ?? or 7^4 (=2401)
6th term = 16807 or 7^5
7th term = 117 647 or 7^6
nth term = (7)^(n-1)
Answer:
y=-1/3x-1
Step-by-step explanation:
1. Find the slope.
Start from the point on the y-axis and count down and over until you get to the other point marked on the graph. This gets you -1/3
Slope is -1/3
2. Find where the line crosses the y-axis. This is the y-intercept. On this graph, the line crosses the y-axis at (0,-1). The y-value is the intercept.
3. Put the equation in slope-intercept form. Slope intercept form is y=mx+b with mx being the slope and b being the y-intercept.
y=-1/3x-1
