Answer:
155
Step-by-step explanation:
The pattern is the previous number*2 and then +5
5*2=10+5=15
15*2=30+5=35
35*2=70+5=75
Hope this helps
Answer:
Step-by-step explanation:
The translation to a math expression is ...
<em>The sum of a number and 5 is negative 28.</em>
x + 5 = -28
Subtract 5 from both sides of the equation:
x + 5 - 5 = -28 -5
x = -33
The number is negative 33.
The inverse trig ratios, you can find the angle measure, given two sides.
Inverse Tangent: If you know the opposite side and adjacent side of an angle in a right triangle, you can use inverse tangent to find the measure of the angle.
Answer:
(2.5, -1)
Step-by-step explanation:
The midpoint of a line segment is just the average position of the 2 endpoints.
(x1, y1) = (1, 2)
(x2, y2) = (4, -4)
Find the average x-coordinate by adding them up and dividing by 2:
Do the same for the y-coordinate:
Using those, the coordinate of the midpoint is (2.5, -1)
