The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
We have m = 3 and b = -3. Substitute:
<h3>y = 3x - 3</h3>
Respuesta: 4.5 pies que puede comprar si tiene $ 11.25
Explicación paso a paso:
Dado que hemos dado que
Costo de los dulces por pie = $ 2.50
Dinero total que gastó en dulces = $ 11.25
Sea x el número de pies que puede comprar
Ahora, según la pregunta, obtenemos eso,
Entonces, 4.5 pies que puede comprar si tiene $ 11.25.
This is Bridge Algebra 2 stuff. Well you see that 2x+y=8 and x-1=y. To slove for y you have to slove for x first to find y. So 2x+x-1=8 ( the reason I did that is because there is a y in that equation and I placed it on that equation) now lets slove this equation for x. So 3x-1=8( I add 2x with x) 3x=9 ( I made -1 a positive one and add it to 8) x=3 ( I divided 9/3 to get 3). Now that you have slove x we will use x to slove for y. So 3-1=y, 2=y. Your answer is y=2.
1. 2.50x + 5 = C
2.50(4.1) + 5 = C
$15.25
2. 15.25(1.15)
$17.54
3 B, I believe but dont quote me.
