So we don't have to multiply each domain, we just need to find the lowest and highest domain and put it into the equation (since we're just multiplying)
-4 and 4 are the lowest and highest.
3.2×-4=-12.8; this means that when 4 is put into the equation, it will be 12.8 since they're opposites.
So, the range is -12.8 to 12.8.
Evaluate : 8 - 9 + (-2)
8-9= -1 (because if you take away 9 from 8, you will end up with a negative number since there isn’t enough to take away.)
-1 + -2 = -3 (this is because when you are adding two negative numbers together, you will basically just add -1 and -2 as you would normally, then you would transfer the negative sign as well to make it -3)
Finally, your answer to this question is -3.
Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
Answer:5
Step-by-step explanation: you have to dived into two groups into five.
A nickel is worth 0.05 and a quarter is worth 0.25.
Multiply number of nickels by the worth and quarters by their worths. Add together to equal total value:
The equation is:
0.05n + 0.25q = $40
