Answer:
0≤y10
Step-by-step explanation:
Given the expresssion;
y = 10 - 0.05x
To get the range, we will first substitute for the value of y by substituting the value x =0
y = 10 - 0.05(0)
y = 10
Hence the required range of values falls between 0 and 10;
0≤y10
The answer to the problem is 12
Answer:
don't know
Step-by-step explanation:
Y = 4x - 1
y = 2x - 5
4x - 1 = 2x - 5
4x - 2x = -5 + 1
2x = -4
x = -4/2
x = -2
y = 4x - 1
y = 4(-2) - 1
y = -8 - 1
y = -9
solution is : -2,-9)
Answer:
1/5
Step-by-step explanation:
2/3 - 7/15
Now when dealing with fractions, alas make the dominator ( bottom number the same), and the rule of thumb is, whatever u do to the bottom, must be done to the top
2 7
-------- - - - - - -
3 15
So now u should think, how to make 3 to 15, so u multiply it by 5, therefore u would also need to multiply it to the top
2 x 5 7
-------- - - - - - -
3 x 5 15
10 7
-------- - - - - - -
15 15
Now just minus horizontally ( u don't need to minus the dominator)
3
---------
15
Now can u make this fraction smaller? As in, is there a number that u can divide to the top and bottom, yes, that number is 3 in this case
3 ÷3
---------
15 ÷3
= 1
- - - - -
5
Thats your final answer
