Answer:
15 feet
Step-by-step explanation:
We have 2 similar right triangles with legs height and length of shadows.
height of men : length of shadows of the man = height of tree : length of shadows of the tree
5 : 8 = x : 24
8x = 5* 24
x = 5*24/8 = 15 (feet)
Respuesta:
3x-y-1 = 0
Explicación paso a paso:
La forma estándar de ecuación de una línea se expresa como y = mx + b
M es la pendiente
b es la intersección con el eje y
Dada la coordenada P1 (2,5) y P2 (4,11)
Pendiente m = y2-y1 / x2-x1
m = 11-5 / 4-2
m = 6/2
m = 3
Sustituya m = 3 y (2,5) en y = mx + b
5 = 3 (2) + b
5 = 6 + b
b = 5-6
b = -1
Obtén la ecuación
y = 3x-1
Igualar a cero
y - 3x +1 = 0
Multiplicar por -1
3x-y-1 = 0
Esto da la ecuación requerida
Answer:
x=92 y=23
Step-by-step explanation:
Let them be x and y respectively
so given
x-y=69
and
x/y=4 x=4y
so we can write
x-y=69
as
4y-y=69 3y=69 y= 69/3 = 23
now y is 23
so putting in any equation will give the value of x
so
x-23=69 x=92
Subtract 2 from 12. 12-2 is 10. You can subtract 10 with 4, and then add 2. (10-4)+2=8.
I worked this out, and the answer is B.) 14x+6
Hope it helped! :3
