Looking at this, I think the easiest (personally) way to solve it would be using the Substitution method.
Meaning we have to rearrange ONE equation, to make ONE variable ( x or y) the subject.
(1) 2.5x + y = -2
(2) 3x +2y = 0
The first equation is the easiest to rearrange. Make Y the subject for (1).
Thus,
y = -2.5x - 2
Substitute this into equation (2).
∴ 3x + 2(-2.5x - 2) = 0
Expand and simplify:
3x - 5x - 4 = 0
∴ -2x - 4 = 0
Making x the subject:
-2x = 4
x = -2
From here, we need to substitute x=-2 into equation (1) or (2) to solve for the y-value. I would say the easiest way, would be to rearrange one, to make y the subject, which was what we did earlier.
Thus,
y = -2.5x - 2
y = ((-2.5(-2) -2)
y = 3
(X,Y) x = -2, y = 3
Answer: (-2,3)
I hope you followed through.
Answer:
An explicit attitude is the kind of attitude that you deliberately think about and report. For example, you could tell someone whether or not you like math. Implicit attitudes are positive and negative evaluations that are much less accessible to our conscious awareness and/or control.
Explanation:
these have chagnged because people are more open minded these days they want to say whats on their mind take protesting for an example.
May i be marked brainliest?
Answer:
Hominids
*Appeared 3 to 4 million years ago in souther and eastern Africa.
*Humanlike creatures called primates
*Mary and Louis Leakey excavated hominid fossils in the Great Rift Valley
*"Lucy," and Australopithecine fossil, found in 1974.
*Three major differences from earlier primates: bipedalism (gives ability to walk upright), a sizable brain (enables abstract thought and fine motor control), and a larynx (allows for complex speech)
*Thought-processing ability led to alteration of the natural environment to suit human needs
Neither of those were developed to prevent global warming,in both cases that turned out to be one of the many potential positive results if the technology were widely accepted and implemented
