Answer:
Option D. No solutions
Step-by-step explanation:
we have
-----> equation A
----> equation B
Multiply by -3 both sides equation A
-----> equation C
Compare equation B and equation C
Equation B and equation C are parallel lines with different y-intercept
<u><em>Verify</em></u>
For x=0
<em>Equation C</em>
----->
The y-intercept is the point (0,0.5)
Equation B
----->
The y-intercept is the point (0,-0.5)
therefore
Lines do not intersect
The system has no solution

Answer:
y = 90
Step-by-step explanation:
If y varies jointly as x and z, then;
y = kxz
If y = 18 when x = 2 and z = 3
18 = k(2)(3)
18 = 6k
k = 18/6
k = 3
To get y when x = 5 and z = 6
y = kxz
y = 3(5)(6)
y = 15*6
y = 90
Hence the value of y is 90
3/5 is the correct answer for sin s
Answer:
Step-by-step explanation:
Let x be the number of weeks that it will take Andy to reach his goal.
We have been given that Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.
Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.
Therefore, the equation can be used to determine x, the number of weeks that it will take Andy to reach his goal.
