Answer:
Y= -3-12
Step-by-step explanation:
Plug in the coordinates. 3= -3(-5) +b. Solve.
Answer:
-4
Step-by-step explanation:
Absolute value is the distance from one number to the next, so it can't be negative. I-7+3I is 4.
- * 4 is equivalent to -1 * 5 so the answer is -4.
Answer:
(2.4)(-1.8) and (0.6)(-0.4)
Step-by-step explanation:
The product of two negative numbers = a positive number. (negative × negative = positive).
Product of two positive numbers = a positive number. (Positive × positive = positive)
Product of a negative number and a positive number = a negative number. (Negative × positive = negative).
Therefore, the answer choice that shows two products that both will result in negative values would be the answer choice that has a negative number multiplying a positive number.
Option 3 has two products in which each has a negative and positive number. That is (2.4)(-1.8) = a negative value, and
(0.6)(-0.4) = a negative value.
Therefore, the answer is Option 3: (2.4)(-1.8) and (0.6)(-0.4)
<u>Answer-</u>
<em>The height of the traffic light is 21.8 feet.</em>
<u>Solution-</u>
As shown in figure, we can see the right triangle formed from the situation,
From the question,
BC = the distance walked by Andrew from the traffic light = 20 feet
Height of Andrew's eye = 5 feet
Height of the traffic light = AB + Height of Andrew's eye
From the properties of triangle,
Therefore, height of the traffic light = AB + Height of Andrew's eye = 16.8+5 = 21.8 feet

Answer: The interior angles are 38, 52, 90 </h3>
=======================================================
Explanation:
The exterior angle of 142 leads to an interior angle of 180-142 = 38. The adjacent interior/exterior pair of angles always add to 180. So 38+142 = 180. These two angles are supplementary, which is another way of saying they form a straight line.
Since 38 is one of the acute interior angles, the other acute interior angle is 90-38 = 52. The rule is that the acute interior angles of any right triangle always add to 90 degrees (i.e. the angles are complementary).
Lastly, the remaining interior angle is the 90 degree angle itself. All right triangles have exactly one angle that is 90 degrees. The term "right angle" is often used in place of "90 degree angle".
