Answer:
1. A(1;5), B(10;23), slope of 2
2. A(10;9), B(4;0), slope of 1.5
3. A(-35/4;6), B(9;-35/6), slope of -2/3
4. A(5;18), B(25,22), slope of 0.2
5. A(2/9;1/3), B(2/3,-1/3), slope of -1.5
Step-by-step explanation:
Substitute values with correct variable and slopemis coefficient of x when x and y-int. are on 1 side, y is on other side and has coefficient of 1. Hope it works!
T 1 2 3 4
B 3 6 9 12
This is linear relationships B=3*T (it can be also called directly proportional)
Answer:
not equivalent
Step-by-step explanation:
Given
= 
If the ratios are equivalent then ib cross- multiplying the 2 sides should be equal, that is
6 × 9 should equal 7 × 7
However, 54 ≠ 49
Thus the ratios are not equivalent
Answer:
a) 1325 frogs b)75.47 hours
Step-by-step explanation:
start = 150 frogs
after 4 hours = 530
1) figure out how many frogs per hour 530/4 = 132.5 frogs per hour
2) 10 hours after initial time * 132.5 frogs = 1325 frogs
3) Time to reach 10000 frogs is => 10000 / 132.5 = 75.47 hours
She is incorrect
the GCF of 2, 4 and 8 is 2 (not 8 has she has written)
the GCF of x2, xy and xy4 is x not x2y4
Correct GCF of the 3 terms is 2x
