Answer: -6
Step-by-step explanation:
-3 - 3 = -6
because when you have a minus number and subtract another number it is like its going up like:
-1 - 3= -4
but if you look on a number line it a clearly going down.
Hope this helped u.
Answer:
m = -21
Step-by-step explanation:
9+m/3=2
1. Subtract 9 from both sides
9 - 9 + m/3 = 2 - 9
m/3 = -7
2. Multiply both sides by 3
3 (m/3) = -7 (3)
m = -21
Answer:
Algebra is a language of symbols and operations to study the general properties of numbers. It is essential for solving many problems involving rates, costs, length, and weight. It is commonly considered to be one of the most important branches of mathematics and it has been extensively used in both pure and applied sciences.
Step-by-step explanation:
Sin, cos and tan <span>are </span>used in trigonometry to express the ratio of two sides of a triangle. The number is influenced by the angles. The 3 sides can be called:
1. adjacent: the side that near the angle
2. hypotenuse: the diagonal line
3. opposite side: the side that doesn't touch the angle.
Sin is the ratio of opposite side with the hypotenuse.
Cos is the ratio of adjacent side with the hypotenuse
Tan is the ratio of opposite side with the adjacent side. It also called ratio of sin with cos.
If put into equations it will be:
sin= opposite/ hypotenuse
cos= adjacent/hypotenuse
tan= sin/cos= opposite/adjacent
Answer:
-3
Step-by-step explanation:
Square root of 9 is 3,
so the negative square root is -3.
