The rate of change is given as 10 per day--the number of cans the class plans to bring each day.
After 10 days at that rate, the change will be 10*10 = 100. Since the total after 10 days is 205, we compute the initial value as 205 -100 = 105. This is the number the teacher already had.
cans = 10*days +105
Answer:
x = 5.95
Step-by-step explanation:
Given
= 3.5
Multiply both sides by 1.7 to clear the fraction
x = 1.7 × 3.5 = 5.95
True: The trigonometric ratios sine and secant are reciprocals of each other
Answer:
See below
Step-by-step explanation:
<u>Point -slope form is:</u>
By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.
<u>How to find the slope?</u>
Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2
<u>Use the formula:</u>
<u>Example:</u>
- m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
Answer:
68
Step-by-step explanation:
LM + MN = LN
x + 7 + 3x + 20 = 6x - 5
4x + 27 = 6x - 5
-4x -4x
27 = 2x - 5
+5 +5
32 = 2x
÷2 ÷2
16 = x
MN: 3x + 20
3(16) + 20
48 + 20
68
