Answer:9x-9=7 or 9x-9=-7
Step-by-step explanation:
An absolute value is the distance from zero, therefore the answer can not be negative. In this case, 9x-9=7 and 9x-9=-7 both work, because 7 and -7 are the same distance from zero.
Beatrice is incorrect. All of these points are not on the same line because the slope between (-2 , -1) and (1, 0), which are coordinates from each of these pairs above are not equal to 1/2
Answer:
Step-by-step explanation:
They're asking for what other information is needed.
We were given triangle ABC is congruent to triangle DEF. We know for certain line AB and line DC are congruent to each other as well as lines BC and EF.
The additional information we need to know is if line AC is congruent to line DF to absolutely be sure.
Remember SSS by definition is: Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other. If all three sides in one triangle are the same length as the corresponding sides in the other, then the triangles are congruent.
Answer:
The answer is B. After 20 seconds car A will be traveling at 65mph. This is because the speed is increasing 0.2 per second so 0.2 times 20 would equal 4. 61+4=65 Car B will be travelling at 65mph too because it is decreasing 0.5 per second and 0.5 times 20 would equal 10 and 75mph - 10mph would equal 65mph. The answer is A

Answer:
13
Step-by-step explanation:
The vector GH has horizontal and vertical components of 5 and 12. You recognize that these are part of the Pythagorean triple (5, 12, 13), so the length of GH will be 13.

In case you haven't run across this fun fact often enough to remember it, you can compute the length from the distance formula:
d = √((x2-x1)² +(y2-y1)²) = √((-1-4)² +(10-(-2))²) = √((-5)² +12²)
d = √(25+144) = √169 = 13
