Answer:
(3,1) because x is 3 and y is 1.
Step-by-step explanation:
x+2y=5
3x+5y=14
Multiply first equation by 3:
3x+6y=15
3x+5y=14
Subtract 3x:
1y=1
Therefore, y = 1
Plug it back into 1st equation:
x+2(1)=5
x+2=5
Therefore, x = 3
Judging from your answers, it looks like (3,1) because x is 3 and y is 1.
I hope this helped!
This is easy
69 because it says after two shoveling jobs he starts to get 9 pennies a job the first two jobs were only worth 3 pennies each so 3+3=6 so 6+9x7=69

A possible solution to the inequality is 2 hotdogs and 8 tacos.
Let x represents the number of hotdogs purchased and y represents the number of tacos purchased.
Gabriella has $30 to spend and must buy a minimum of 9 hotdogs and tacos altogether.
Hence:
4x + 2y ≤ 30 (1)
x + y ≥ 9 (2)
Also:
x ≥ 2 (3)
A possible solution to the inequality is 2 hotdogs and 8 tacos.

The discriminant is 164 and there are two real solutions.
What is Quadratic equation?
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax^2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
We can find the discriminant as shown below:
x^2+14x+8=0
a=1, b=14, c=8
Discriminant=b^2-4ac
=(14)^2-4*1*8
=196-32
=164>0
As the discriminant is positive and greater than zero. So, there are two real and distinct solution.
Hence, discriminant is 164 and two real solution.
