Answer:
2
Step-by-step explanation:
Slope (m) is equal to the change in the y-coordinate divided by the change in the x-coordinate.
The change in y= 6
The change in x= 3
6/3 =2
Answer:
y = 3x -5
Step-by-step explanation:
6x - 2y = 10
-6x. -6x
Inverse Operations
-2y = -6x + 10
÷-2. ÷-2. ÷-2
y = 3x - 5
Answer: d.) None of the answer choices is correct
Step-by-step explanation:
The homework score is an independent variable (known) and on the x-axis, while the midterm exam is the dependent variable, so it's on the y-axis
y = 0.91x - 94.4; and x=420
Substitute x as 420 into the equation.
y = 382.2 - 94.4 = 287.8, or approximately 288.
And this value isn't in the options above.
Answer:
6
Step-by-step explanation:
Answer: 93
Step-by-step explanation:
To solve this problem, we need to use the order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
For multiply/divide and add/subtract, you don't necessarily go in that specific order. You go from left to right, depending on what comes first. For example, if division comes before multiply, you would divide first, then multiply. Same goes for add/subtract.
9²+3×(9-5)²/4 [solve parenthesis]
9²+3×(4)²/4 [solve exponent]
81+3×16/4 [solve multiply or divide, whichever comes first]
81+12 [solve add or subtract, whichever comes first]
93
Now, we know that 93 is our final answer.
