Let's solve this by substitution.
y is given by the 2nd eqn as y = (1/3)x + 7. Subst. (1/3)x + 7 into the first eqn as a replacement for y: x + 9( (1/3)x + 7) = 3.
clear out fractions by mult. all 3 terms by 3: 3x + 9x + 63 = 3
Combine like terms: 12x = -60. Then x = -5
Find y by subst. -5 for x in the 2nd equation: y = (1/3)(-5) + 7
= -5/3 + 35/3 = 30/3 = 10.
Thus, the solution (x,y) of this system is (-5,10).
Answer:
(4, -23)
Step-by-step explanation:
We are given;
We are needed to determine the point that lies on the equation;
- We need to know that for a point to be lying on the equation it must satisfy the equation.
- This means when we use the value of x in the equation we should get the exact value of y of the given point;
Point (4, -23)
Replacing x = 4 in the equation;
y = -5(4) - 3
= -23
Therefore, the point lies on the equation as the point satisfies the equation
Thus, the required point is (4, -23)
Slope: 0
Y-intercept: 5
The answer is 0,5
I hope this helps.
3(8)-12=12
24-12=12
The fourth choice.
Yeah I think you already got it
The value of 4 is Hundreds.
