Answer:
Choice A: y = 3x + 2
Step-by-step explanation:
<u>Given</u>
y = -1/3x +4
<u>Reciprocate and switch sign</u>
-1/3
-3/1
3/1
<u>Simplify</u>
3/1 = 3
m = 3
<u>Answer</u>
The only answer choice with the slope of 3 is choice A, therefore that would be the answer.
Answer:
j(t)=600*1.09ᵗ⁻¹
Step-by-step explanation:
In 2014, there were 600 jobs.
The next year, the number is expected to grow by 9%.
Since the growth rate is a percentage, this is an example of a geometric sequence.
The nth term of a Geometric Progression is given as:
Uₙ=arⁿ⁻¹
In the first year, population =600
r=(100+9)%=1.09
Therefore the function j(t) that gives the expected number of jobs from the year 2014 is given as:
Uₙ=arⁿ⁻¹
j(t)=600*1.09ᵗ⁻¹ where t=1,2,3...
The value of t=1 is for the year 2014.
Answer:
use substitution method
find equation for value of x/y
2x + 2y = 4
2y = 4 - 2x
y = <u>4 - 2x</u> ----> equation 1
2
so..substitute the
equation 1 to -5x+3y=-18
-5x+3( <u>4 - 2x</u><u> </u><u>)</u> = -18
2
-5x + 3(2-x) = -18
6-3x = -18+5x
6+18= 5x+3x
24 = 8x
<u>2</u><u>4</u> = <u>x</u>
8
x= 3. -----> eq.2
sub eq.2 into 1 to find the value of x
y = <u>4-2(3)</u>
2
y = - 1
x=3 ; y= -1
To simplifying to 8.4x^100 and it equal too 8.4x^100, and the answer is the same thing.
