Answer:
y-intercept = 2
Step-by-step explanation:
slope, m = -12/8 (please check, post not clear)
P(6,-7)
equation of line using point-slope form
y-y1 = m(x-x1)
y-(-7) = -12/8 (x-6)
y = -3x/2 +9 -7
y = -3/2 + 2
y-intercept = 2
Answer:
-16
Step-by-step explanation:
Yes it does, it is proportional because it increases by the same amount at a constant time (which is each week's paycheck). The constant is the 150. i may be wrong sorry if so.
Tenemos que sean x e y los lados de la huerta entonces el perímetro sería:
P = 2*x + 2*y
Sabemos que el perimetro es 140, reemplazando:
140 = 2*x + 2*y
x + y = 70
despejamos y, nos queda:
y = 70 - x
Ahora tenemos que el área sería:
A = x*y
reemplazamos y:
A = x*(70 - x)
A = 70*x - x^2
Esta sería la ecuación que modela el área de la huerta.
Derivamos e igualamos a 0:
0 = 70 - 2*x
x = 70/2
x = 35
ahora calculamos y:
y = 70 - 35
y = 35
El área máxima sería:
A = 35*35
A = 1225 m^2
Answer:
scale factor = 2
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original
Using the bases of the 2 triangles , then the scale factor is
S → L = = 2
