Answer:

j=m-10

Step-by-step explanation:

If j respresentst he time Jacob spent in the test and m the time Mark spent on the test. We can write an expression that shows the amount of Time Jacob spent on the test compare to Jacob:

We know that Jacob finished the test 10 minutes before Mark.

Let j equal the Total time Jacob spent in terms of Marks time is:

j=m-10

Jacob spends m-10 on the test compared to Mark

Cual de las siguientes rectas es paralela a la recta 8x-2y-7=0?
vazorg [7]

Answer:

b) and c)

Step-by-step explanation:

8x-2y-7=0

y = 4x - 7/2 = 4x -3.5

y = mx + b            m: slope

m = 4

both b) and c) slope is 4

parallel line has same slope (línea paralela tiene la misma pendiente)

una pelota se mueve con movimiento uniforme con una velocidad de 0,25 km/seg calcular la distancia que recorre si tarda en llega
astra-53 [7]

La respuesta correcta es 1.25 km

Explicación:

En general, la distancia que recorre un cuerpo es igual a su velocidad multiplicada por el tiempo que dura el movimiento. Es decir que la formula general es d (distancia) = v (velocidad) x t (tiempo). En este caso sabemos que la velocidad es 0,25 km/seg y el tiempo es 5 segundos. Es decir que la distancia es igual a 0,25 km/seg x 5 seg = 1. 25 kilómetros. De acuerdo a lo anterior la distancia que recorre la pelota es de 1.25 kilómetros.

The functions f(x) = (x + 1)2 - 5 and g(x) = -(x - 2)2 + 3 have been rewritten using the completing-the-square method. What is t
emmasim [6.3K]

f(x) has vertex = (- 1, - 5 ) and is a minimum

g(x) has vertex = (2, 3 ) and is a maximum

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum

to determine if maximum/ minimum

• if a > 0 then minimum

• if a < 0 then maximum

g(x) = - (x - 2)² + 3 is also in vertex form with a < 0

vertex = (2, 3 ) and is a maximum
