Answer:
Simplify the equation
Step-by-step explanation:
4x + 1 + x + -4
= 4x + x + 1 - 4
= 5x + -3
= 5x - 3
Hope this helps
Answer:
Non-proportional; the rate of change is $40/hour
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and the line passes through the origin</u>
Let
x -----> the number of hours
y ----> The total charge in dollars
The equation of the line in slope intercept form is equal to
where
m is the slope
b is the y-intercept
we have
substitute
This relationship is not proportional, because the line not passes through the origin
therefore
Non-proportional; the rate of change is $40/hour
12.4 because 62 divided by 5 = 12.4
Answer:
For #14, (around) 108 times.
#15 = 53
Step-by-step explanation:
14)
2.69*10^5 = 269000
2.5*10^3 = 2500
269000/2500 = 107.6
Rounding up, we get 108
15)
√(53 - 8)2 + (31 - 3)2
= √(45)2 + (28)2
= √2809
= 53

Your answer will be x • 4³ = 64x
When simplifying powers, the rule is that if you’re dividing two powers with the same base (in this case the base is 4), you need to subtract the powers. For example, 3³ ÷ 3² = 3 (which is 3^1).
Using this rule, we can see that 4^8 ÷ 4^5 = 4^(8-5) = 4³.
The x is on top of the fraction and we’re not dividing by an x, so it doesn’t change. Therefore your final answer is 64x.
