Answer:
Step-by-step explanation:
3y = 2x - 9
2y = -3x + 4
3x + 2y = 4
-2x + 3y = -9
6x + 6y = 8
-6x + 9y = -27
15y = -15
y = -1
3(-1) = 2x - 9
-3 = 2x - 9
6 = 2x
3 = x
(3, -1)
Answer:
$17.97
Step-by-step explanation:
add everything up
- bananas: 6(0.75) = $4.50
- rice milk: $3.49
- strawberries: 2(4.99) = $9.98
The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x
so the coordinate for x is -b/2a, for your problem a=-4 b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.
The vertex is (-2, 5)
Answer:
0
Step-by-step explanation:
According to the <em>Slope-Intercept</em><em> </em><em>Formula</em><em>,</em><em> </em>[y = mx + b], <em>m</em><em> </em>represents the <em>Rate of Change</em> [<em>Slope</em>]. Since we ONLY have the y-intercept of [0, 7], that makes the slope 0.
