Answer:
3
Step-by-step explanation:
in slope-intercept form, the slope is the x's coefficient, which in this case is 3,
so, m=3
3x - 5y = 7
2x + 3y = 11
multiply the first equation by 2 and the second by -3:-
6x - 10y = 14
-6x - 9y = -33 Adding these 2 equations we eliminate the term in x:-
-19y = -19
y = 1
Substtute y = 1 in the first equation:_
3x - 5(1) = 7
3x = 12
x = 4
Answer is x=4,y=1 Answer
Second system of equation:-s
Here one equation is linear and the other is quadratic so we substitute fro y in the quadratic:-
From second equation y = 10x - 38, so substituting:-
10x - 38 = x^2 - 4x - 17
Gotta go right now . Sorry
Solve for x right ? . if u find for x . the answer ís x=-2
Answer:
<h3><u>48 people</u> is the right answer.</h3>
Step-by-step explanation:
Let the number of male and female be 3x and 5x
There are twelve more females than males
According to the above problem,
Therefore, the numbers of male is
and number of female is
Hence, total number of people are
There are <u>48 people</u> in the party.
You plug the (2x-4) in for y to look like 6r-3(2x-4)=12. then when you solve and subtract the 12 from the other 12 you’re left with 6r-6x=0. divide the 6 out and the answer is r=x all real numbers.
