Answer:
Step-by-step explanation:
-5x - 10y = 15
<u>-3x + 10y = 25 </u>+
-8x = 40
x = -5
.
Substitute the value of x to one of equations
-5(-5) - 10y = 15
25 - 10y = 15
-10y = 15 - 25
-10y = -10
y = 1
Answer:
An experimental study
Step-by-step explanation:
An experiment deliberately imposes some treatment on individuals in order to observe their responses.
An experimental studies formulates some conditions in order to make an inference. An observational study tries to gather information without disturbing the scene they are observing.
This is then an experiment because people are deliberately asked to taste two muffins and asked for their response.
Hi hello how are you i’m doing this quick
A plus charges $60 per hour and $80 as their 1 time fee
quality plumbing charges $50 an hour with $150 as the one time fee
false, a plus charges 380 and quality charges 400
hope this helps :)
Answer: 5+sqrt(97)/12, 5-sqrt(97)/12 or we write it as [5+/-sqrt(97)]/(12)
5x=6x^2-3
6x^2-5x-3=0
x=-b+/-sqrt(b^2-4ac)/2a
x=-(-5)+/-sqrt((-5^2-4(6)(-3))/2(6)
x= 5+/-sqrt(97)/12
And decimal form is;
x=1.237, -0.4041
