Answer:
4/6 6/9 8/12 10/15 and so on, just multiply both the numerator and denominator by the same number and get your answer.
Step-by-step explanation:
Let's solve your equation step-by-step.
-9 ÷ 3 + b = -1
Step 1: Simplify both sides of the equation.
<u>−9</u>
3
+b=−1
−3+b=−1
b−3=−1
Step 2: Add 3 to both sides.
b−3+3=−1+3
b=2
Answer:
b=2
Answer:
C) 12
Step-by-step explanation:
These type of questions is basically asking you to replace x with 2. f(x) is the same thing as y = but inside the f(x) is the value of x. So in this case, the numerical value of x is 2. All we need to do is replace x with it's numerical value, 2, and solve the equation.
Y = 8x + 40.
Y = score, and x = hours of homework.
Substitute 3 into x
8 x 3 = 24
24 + 40 = 64
So the model predicts a score of 64 for 3 hours of homework.
Hope this helps.
