Answer:
-5 + 3(7.2 - 3.2) equals 7.
Step-by-step explanation:
The order of operations states the order in which different mathematical operations should be done first, you can use the mnemonic PEMDAS to remember the order to complete each operation. PEMDAS states that the order must be followed as Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction. In the expression -5 + 3(7.2 - 3.2), the three mathematical operations being used are subtraction, multiplication, and parenthesis, so based on PEMDAS, the order to complete them is parenthesis, multiplication, and subtraction. -5 + 3(7.2 - 3.2) = -5 + 3(4) = -5 + 12 = 7, so that is your final answer.
Answer:
y = 2x - 6
Step-by-step explanation:
Use the slope-intercept form of the equation of a line.
y = mx + b
y = 2x + b
4 = 2(5) + b
4 = 10 + b
b = -6
y = 2x - 6
Answer:
511.425
Step-by-step explanation:
Easy add them all together = 2045.7 then divide by how many numbers are there so 4 thats 511.425 and theres ur answer please mark me as brainlest!
I do not know if you mean x² or 2x, so here are both equations:
Equation 1:
x² - 16 = 0
x² = 16
x = √16
x = <span>±</span>4
Solutions: x = 4 and x = -4
Equation 2:
2x - 16 = 0
2x = 16
x = 8
Solution: x = 8
