Answer:
1. a. A
2. c. C
3. a. A > C
Step-by-step explanation:
<em>Absolute value is the translation of the number inside | ? | into a positive number. </em>
<em>Examples:</em>
| -245 | = 245
| -47 | = 47
| 69 | = 69
| 21 | = 21
| -4 | = 4
The answer is 50
The answer is 50 because it told you that he had 40 seeds with 4 packets and if you add another packet it makes 50 because each packet had 10 in it
Answer:
formula: y-y1 = m(x-x1)
Step-by-step explanation:
General:
1. find 2 points directly on the line and apply the formula y2-y1 over x2-x1 this answer equals m
2. then add it into the formula y-y1 = m(x-x1) remember x and y are variables so only put numbers in y1 and x1
3. solve the problem
Example:
line 1:
1. y2-y1 over x2-x1 is 4-6 over 6-4 = -1
2. y-6 = -1(x-(-4) or y-6 = -1(x+4)
3. y-6 = -1x-4
4. y = -1x-2
3. the gradient equals: y = -1x-2
Hope this helps :) Let me know if you need a better example
Answer:
Step-by-step explanation:
P(x) = x² - 1 and Q(x) = 5(x - 1)
(P - Q)(x) = x² - 1 - 5(x - 1)
= x² - 1 - 5x + 5
= x² - 5x + 4
Let x be the original number of chocolates:-
x - (2/3)x - (1/5)(x - (2/3)x) = 12
x - (2/3)x - (1/5)x + (2/15 )x = 12
15x - 10x - 3x + 2x = 180
4x = 180
x = 45
original amount of chocolates = 45
