Answer:
rtt6655r55
Step-by-step explanation:
So, as you can see, there are actually two equations here:
x- 4 = 0 and 8x+64=0
So, we need to solve both of them to get the solution.
x-4=0
x = 4
8x+64=0
8x=-64
x=-64/8
x=-8
So, the correct answer is C. x=4 and x=-8
Answer:
see below
Step-by-step explanation:
<em>Which of the equations from part A represent adding two rational numbers?</em>
Equations A, C, E
<em>What hypothesis can you make about the sum of two rational numbers?</em>
The sum of two rationals will always be rational
<em>Will the addition result in a rational or an irrational number?</em>
Our hypothesis is that the result is always rational. This can be justified by the fact that the sum of two rationals a/b + c/d, where a, b, c, d are integers and bd≠0, is (ad+bc)/(bd), a rational, based on closure of integers for multiplication and addition.
<em>Which equations represent the sum of a rational and an irrational number?</em>
Equations B, F
<em>What hypothesis can you make about the sum of an irrational and a rational number?</em>
The sum of a rational and irrational number is always irrational.
we are given
parent function as
(1)
vertical stretch of factor 2
so, we can multiply y-value by 2
then a shift right of 3 units
so, we can replace x as x-3
(2)
a shift left by 2 units
we can replace x as x+2
then a horizontal shrink factor of 1/2
so, we can multiply by 2 to x-value
then a shift down of 5 units
we can subtract y-value by 5
so, we get
(3)
a shift to the right 1 unit
we can replace x as x-1
stretched vertically by a factor of 1/2
we can multiply y-value by 1/2
then is shifted down 4 units
we can subtract y-value by 4
(4)
reflected across the x-axis
we can multiply y-value by -1
tretched vertically by a factor of 3
multiply y-value by 3
shifted left 7 units
we can replace x as x+7
<span>−ax + 2b > 8
</span>⇒ -ax> 8-2b
⇒ x< (8-2b)/(-a)
<span>
The final answer is </span>x< (8-2b)/(-a)~
