Answer:
C. 2(z + 3).
Step-by-step explanation:
z + (z + 6)
= z + x + 6
= 2z + 6
= 2(z + 3).
Answer:
8,000 grams. if there are 1,000 grams in a kilogram that means 8 times 1,000 which would be 8,000.
1) The error occurred when you moved the decimal place one spot to the left without changing the exponent of 10 to go along with it.
Not changing the exponent will change the entire value of the answer. By changing 10.35 to 1.035, we made our answer 10 times smaller, so in order to compensate for that, we need to make 10^10 ten times bigger by changing it to 10^11.
2) 10.35 x 10^10 gets changed to:
1.035 x 10^11
3) The strategy we used is to apply proper scientific notation to our answer. We should recognize when we drastically change the value of our original answer.
Answer:
85 square ft
Step-by-step explanation:
8.5cm times 4 cm = 34 cm
34 cm times 2.5 (because 1 cm = 2.5ft) = 85 square ft
Answer:
Part 1) There are infinity locations for the point B
Part 2) see the explanation
Step-by-step explanation:
Part 1) How many possible locations are there for point B?
we know that
The equation of a line in point slope form is equal to

where


substitute

Convert to slope intercept form




Point B can be any point ( different from point A) that satisfies the linear equation
therefore
There are infinity locations for the point B
Part 2) Describes a method to location the point
To locate the point, one of the two coordinates must be known. The known coordinate is placed into the linear equation and the equation is solved to find the value of the missing coordinate
Example
Suppose that the x-coordinate of point B is 4
For x=4
substitute in the linear equation

so
The coordinates of point B is (4,10.5)
