Answer:
Las reglas para escribir un número en forma estándar es que primero escribes un número entre 1 y 10, luego escribes × 10 (a la potencia de un número). En una calculadora, generalmente ingresa un número en forma estándar de la siguiente manera: Escriba el primer número (el que está entre 1 y 10). Presione EXP
Step-by-step explanation:
The slope is 0
y2-y1/x2-x1

Answer: the speed of the plane is 130 mph
Step-by-step explanation:
Let x represent the speed of the plane. If the car travels 80 mph slower than the plane, then the speed of the car would be (x - 80) mph.
Time = Distance/speed
plane can fly 520 miles in the same time as it takes a car to go 200 miles. This means that the time it takes the plane to fly 520 miles is
520/x
Also, the time it takes the car to drive 200 miles is
200/(x - 80)
Since the time is the same, it means that
520/x = 200/(x - 80)
Cross multiplying, it becomes
520(x - 80) = 200 × x
520x - 41600 = 200x
520x - 200x = 41600
320x = 41600
x = 41600/320
x = 130 mph
Answer:
y = 0.75x - 1.75
Step-by-step explanation:
To find the slope we do (Y1 - Y2)/(X1-X2) aka rise over run
So, m = (-1 - 2) / (1 - 5)
m = 0.75
Now we have y = 0.75x +b
We can plug in x and y values to find b
2 = 0.75(5) +b
b = -1.75
Therefore,
y = 0.75x - 1.75
