Answer:
y= -5x +7
Step-by-step explanation:
We can see points on the graph:
The function in general form is:
Let's find the slope and y-intercept as per identified points on the graph:
b= y- mx
- b= - 3 -(-5)*2= -3 +10= 7
Based on the found values of m and b, the given line is:
If we know that 6 things cost 2.99 and we want to know unit price we just have to divide 2.99 by 6.
So 2.99:6=0.49$ - its the result.
Now we can say that his sister is not correct, because price is different that 2$/unit.
3-7= -4
2×-4= -2
I think i did that right...
Answer:
The least common multiple of 6, 15 and 40 is <u>120</u>.
The least common multiple of 32, 48 and 72 is <u>288</u><u>.</u>
The LCM of 20 and 24 is <u>120</u>.<em> </em>
The LCM of 30 and 90 is <u>90</u>.
The LCM of 150 is <u>900</u>.
Step-by-step explanation:
<u>Steps to find LCM</u>
- Find the prime factorization of 150. 150 = 2 × 3 × 5 × 5.
- Find the prime factorization of 180. 180 = 2 × 2 × 3 × 3 × 5.
- LCM = 2 × 2 × 3 × 3 × 5 × 5.
- LCM = 900.
