Answer:
(5, 11 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 4 → (1)
y = 2x + 1 → (2)
Substitute y = 3x - 4 into (2)
3x - 4 = 2x + 1 ( subtract 2x from both sides )
x - 4 = 1 ( add 4 to both sides )
x = 5
Substitute x = 5 into either of the 2 equationsfor corresponding value of y
Substituting into (2)
y = 2(5) + 1 = 10 + 1 = 11
solution is (5, 11 )
Answer:
hello!
Step-by-step explanation:
The number 92 is a rational number if 92 can be expressed as a ratio, as in RATIOnal. A quotient is the result you get when you divide one number by another number. For 92 to be a rational number, the quotient of two integers must equal 92.
Eliminate 'y' by equating
<span>8x - 40 = x^2 - 2x - 15 </span>
<span>x^2 - 2x - 8x - 15 + 40 = 0 </span>
<span>x^2 - 10x + 25 = 0 </span>
<span>(x - 5)(x - 5) = 0 </span>
<span>(x - 5)^2 </span>
<span>Hence x = 5 is the only solution for 'x'. </span>
<span>Substitute in to the linear eq;n for 'y' </span>
<span>y = 8(5) - 40 </span>
<span>y = 40 - 40 </span>
<span>y = 0 </span>
<span>Hence the solution in ( x,y) form is ( 5,0).
