Answer:
9x+14y
Step-by-step explanation:
First Multiply the number outside of the brackets with the numbers inside the brackets. Ex:3 x 3x and 3 x -y
17y-2x+3(3x-y)+2x
That should get you to this.
17y-2x+9x-3y+2x
Next combine like terms.
14y+9x
Hope this helps!
Answer:
B. Days that are not Independence Day are not July 4. True
Step-by-step explanation:
"Independence Day in the United States is July 4" is a declarative sentence. It declares or asserts something.
The conditional form of the sentence would be, "IF it is Independence Day in the United States, THEN it is July 4".
The IF part is the hypothesis. The THEN part is the conclusion.
You form the inverse of a conditional statement by negating both its hypothesis and its conclusion:
If it is NOT Independence Day in the United States, then it is NOT July 4".
The closest sentence is, ”Days that are not Independence Day are not July 4." That statement is TRUE.
A and D are wrong. They each consist of two declarative sentences.
C is wrong. The statement is correct, but it interchanges the hypothesis and the conclusion of the original statement.
Answer:
Step-by-step explanation:
According to table we have units:
- Kilo = 1000 ⇒ km = 1000 m
- Milli = 0.001 ⇒ mm = 0.001 m
Comparing the two units we can see that:
- 1 Km = 1000/0.001 = 1000000 mm
Then we can convert the distance in mm to Km:
- 83400000 mm =
- 83400000 / 1000000 km =
- 83.4 km
Correct choice is B

Answer:
2.2236
Step-by-step explanation:
From the R output given, we can obtain the linear regression model in the form ;
y = bx + c
Intercept, c = 9.4764
Slope, b = 0.0315
x = number of manufacturing enterprise employing 20 or more workers
y = annual mean concentration of Sulphur dioxide
Hence, The regression equation model as obtained from the R output is :
y = 0.0315x + 9.4764
For the city of Duarte;
x = 200
Actual annual mean concentration of Sulphur dioxide is 18 micrograms per cubic meter.
Residual = Actual value - predicted value
Prediction using the regression equation to obtain the predicted annual mean concentration ;
The predicted y value, when x = 200
y = 0.0315(200) + 9.4764
y = 15.7764
The residual, if actual annual concentration = 18
Y residual = 18 - 15.7764 = 2.2236
