Your answer is to the question 16,4
<span>Form of the equation: y = mx + b
---
You are given that y = 8 when x = 7.
And you are given that m = -1.2
-----
Substitute for those letters and solve for "b"::
8 = -1.2*7 + b
8 = -8.4 + b
b = 8 + 8.4 = 16.4</span>
Answer:
this basically means that whenever x is increased then y will decrease, but if x is decreased y will increase.
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
perpendicular lines have slopes that are opposite reciprocals
Answer:
4 6/8 + 3 2/3
first make the denominators the same
8 x 3 = 24 3 x 8 = 24
6/8 = 18/24 2/3 = 16/24
4 18/24 + 3 16/24 = 7 34/24
simplify:
34 / 24 = 1 5/12
your answer: 8 5/12
If you need to, you can write and solve an equation for the factor you seek.
... 6×10^10 = factor × 2×10^-3
Divide by 2×10^-3 to find the value of the factor:
... (6×10^10)/(2×10^-3) = factor
... factor = (6/2)×10^(10-(-3))
... factor = 3×10^13
The first number is 3×10^13 times the second number.
_____
An exponent signifies repeated multiplication.
... 10×10×10 = 10³
Just as you cancel common factors when you do division, you can subtract exponents.

The same process works regardless of the signs of the exponents. When multiplying, we add exponents; when dividing we subtract the exponent of the denominator.
