Answer:
c : they will have both saved 97
Step-by-step explanation:
7*6 = 42 + 55(base) = 97
12*6 = 71 = 25(base) =97
Y² + 10z - 10y - yz = (y - 10)(y - z)
Prime factor is a factor that is a prime number.
Prime factors of :
8 : 2 × 2 × 2. Also can be written as

12 : 2 × 2 × 3. Also can be written as

20 : 2 × 2 × 5. Also can be written as

30 : 2 × 3 × 5
56 : 2 × 2 × 2 ×7. Also can be written as

70 : 2 × 5 × 7
You can find all of them by using Factor Tree [ as shown in the picture] or Dividing by prime numbers.
3.9 and 5.3, when rounded off and mult. together, produce the product 20.
Thus, the decimal point must follow the first two digits of your answer, whether estimate or "exact."
3.9*5.3 = 20.67 by calculator.
Y = 3x - 1
The format for slope intercept form is:
y = mx + b
m represents the slope and that was given so:
y = 3x + b
Now we have to substitute the value from the given point into “y” and “x” to solve for “b”
(2) = 3(1) + b
2 = 3 + b
-1 = b
Now that we know b we can substitute it into y = 3x + b to get the equation of the line
y = 3x - 1
