Answer: x < -9
Step-by-step explanation:
-8x > 72
x < -9 when dividing a negative number in an inequality, change the sign to opposite.
the number are less than -9.
A. 6-4=2 YES
12 + 12 = 14 NO
B. 5-3=2 YES
10+9 = 14 NO
C. 3-1 = 2 YES
6+3 = 14 NO
D. 4-2= 2 YES
8+6 = 14 YES
THE ANSWER IS D
Answer:
C, E
Step-by-step explanation:
A. INCORRECT
A is wrong because a reflection across the x-axis DOES move the position of the figure (as it is flipped, so the position changes), but it DOES NOT change the angle (since a shift in position doesn't equal to a change in angle measure)
B. INCORRECT
Although a reflection across the x-axis does change the position of the angle, it DOES NOT change the measure of the angle.
C. CORRECT
A reflection across the x-axis does in fact move the position of the figure and does not change the angle measure. Reflections only deal with flipping a figure, not changing it's shape/distorting it so that the angle will change.
D. INCORRECT
A translation right will change the position of the figure but will not change the measure of the angle.
E. CORRECT
Yes, a translation right WILL change the position of the figure but will NOT change the measure of the angle. This is because a translation is simply moving a figure up and down; it has nothing to do with changing the shape of the figure/distorting it so that the angle is different.
Answer:
Euclid was a great mathematician and often called the father of geometry.
Step-by-step explanation:
Answer:
the sample proportion is higher
Step-by-step explanation:
What we must do is calculate the proportion of the population, we are left with the fact that out of 38 students 58% have cell phones, these are the proportion of the population, then they would be:
38 * 58% = 22.04 students
Now, the sample proportion is 24.
Therefore 22.04 < 24
Which means the sample proportion is higher
