Answer:
Step-by-step explanation:
4x-40=7(-2x+2) multiply inside the parenthesis with 7
4x - 40 = -14x + 14 export like terms to the same side of equation
4x + 14x = 14 + 40 add like terms
18x = 54 divide both side by 18
x = 3
Option D is correct. The correct statement that represents the graph is R: {y E R | y ≥ -3}
From the given graph, we are to get the range.
The range is the output value for which the function of the graph exists. The required output values are the y-values.
From the graph shown, we can see that the range of y is from -3 to 1. This can be denoted as;
Range = [-3, 1)
This shows that the range of the graph are all the values greater than -3 including -3.
The correct statement will therefore be;
R: {y E R | y ≥ -3}

Answer:
6 6/7 km/h
Step-by-step explanation:
The relations between speed, time, and distance are ...
time = distance/speed
speed = distance/time
__
So, to find the average speed, we need to know the total distance and the total time. The distances are given, but we need to compute the times.
time jogging = (2 km)/(8 km/h) = 1/4 h
time walking = (2 km)/(6 km/h) = 1/3 h
Then the woman's average speed is ...
average speed = (total distance)/(total time) = (2 km + 2 km)/(1/4 h + 1/3 h)
= (4 km)/(7/12 h) = 48/7 km/h
= 6 6/7 km/h
Answer:
4000
Step-by-step explanation:
from 1 - 1000 = 300
1's = 100
10's = 100
100's = 100
1000's = 0
300 * 10 = 3000
then add in all the 3000's (ie 3001,3002, etc ) that adds one more thousand
3000 + 1000 = 4000
