Answer:
d = 7.2
Step-by-step explanation:
Step 1: Write out equation
d/1.2 = 6
Step 2: Multiply both sides by 1.2
d = 7.2
Let's have two numbers x (larger) and y (smaller). from the info above...
x + y = 3
5x + 4y = 29
so that means y=3 - x. we can sub this in
5x + 4(3-x) = 29
5x + 12 - 4x = 29
x = 17
then y=3-x=3-17=-14
so it's 17 and -14
answer:
slope = 
that's how you find the slope in any equation
Answer:
b=3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
b
=
3
b=3
Answer:
<u>x = -7.5 - 1.5(n−1) </u>
Step-by-step explanation:
the explicit formula for the arithmetic sequence has the form
x = a + d(n−1)
a is the first term and d is the common difference
The given arithmetic sequence is
-7.5,-9,-10.5,-12
The first term is -7.5
d = common difference = -9 - (-7.5) = -1.5
∴ x = -7.5 - 1.5(n−1)
