Answer: 22.5
Step-by-step explanation: The y-intercept or b would be 22.5 because In point slope form 3.75 is the y, -7.5x is the mx and since -7.5x-3=22.5, 22.5 is the b.

Answer:
(c) output increases, then decreases ...
Step-by-step explanation:
The given function is quadratic, so it has a turning point. Neither linear nor exponential functions have a turning point, so are always increasing or decreasing.*
The second attachment shows a plot of the function with input on the x-axis and output (area of the rectangle) on the y-axis.
_____
* A linear function that is a horizontal line will be neither increasing nor decreasing.
Answer:
2
Step-by-step explanation:
y + 12 = 7y
<em>isolate variable</em>
12 = 6y
<em>divide both sides by 6</em>
2 = y
7 x 60 = 420
420 ÷ 0.91 = 461.5

Answer:
(4, 13/5)
Step-by-step explanation:
Aquí, estamos encontrando el punto que divide el segmento en 1/4
supongamos que tenemos la proporción 1: 4 como a: b
Matemáticamente, el punto que divide el segmento será;
Coordenada x = (bx1 + ax2) / (a + b)
donde (x1, x2) = (3,8)
Al conectar estos valores, tenemos; (4 (3) + 1 (8) / (1+ 4) = (12 + 8) / 5 = 20/5 = 4
Coordenada y = (by1 + ay2) / (a + b) donde (y1, y2) = (1,9)
Conectando estos valores que tenemos; (4 (1) + 1 (9)) / (1 + 4) = (4 + 9) / 5 = 13/5
Por lo tanto, las coordenadas del punto es (4,13 / 5)
