Answer: C: X=2
Step-by-step explanation:
X=2 BECAUSE if u put 2 instead of the x's then it would be 3(2) +8=4(2)+6
PLZ MARK BRAINLIEST
Ans: $((18-6)÷3)
*It is a double-bracket because there is a bracketed equation inside a bracketed equation, so as to separate the values from the unit, in this case, the $ sign. Take 18-6 to find the total cost of the notepads, and take that value divided by 3, the price of one notepad, to find the number of notepads bought.
Answer:
Graph A
Step-by-step explanation
The problem: y=2x^2+8x+3
1) You will need to determine the direction of the parabola, If a > 0 then the parabola opens upward, if a < 0 then the parabola opens downward.
2) If when doing this you get an imaginary solution, you would have no x intercepts. The first thing you need to do is find the x intercepts, you can do this by plugging in 0 for y, so this would give you 0=2x^2+8x+3. Once you have this you start by subtracting 3 from both sides, dividing 8 from both side, etc. (If you would like me to elaborate don't hesitate to ask!)
3) To find the graphs y intercept you plug in 0 for x, which gives you y=2(0)^2+8(0)+3, you do the same thing you did during the previous step for y. (Once again, I am willing to elaborate further if you need!)
4) You then need to find the vertex (h,k)
To find h: h= -b/2a
To find k: k = a(h)2 + b(h) + c
5) Once you've worked through this you can graph the point!
Hope this helped!
