Answer:
Slope is -2.
Hope this helps!
Step-by-step explanation:
To get from 3 to 7 is 4 and 4 to 2 is a -2. 4 divided by 2 is -2. A positive divided by a negative is a negative.
Answer:
x=30
Step-by-step explanation:
1 / 2 ( x + 6) = 18
Distribute
1/2x +3 = 18
Subtract 3 from each side
1/2x +3-3 = 18-3
1/2x = 15
Multiply each side by 2
1/2x*2 =15*2
x = 30
Step-by-step explanation:
Area1=4×3=12cm²
Area2=6×3=18cm²
Area3=(6+3)×(12+4)=9×16=144cm²
Total area = area1 + area2 + area3
Total area= 12+ 18+144=174cm²
Answer: The only difference between the six functions depends on the sides we use.
Step-by-step explanation:
The primary trigonometry ratio are
Sine (sin)
Cosine (cos)
Tangent (tan)
The reciprocal ratio are derived from the three primary functions. Because they can easily be derived, calculators and spreadsheets do not usually have them. These are:
Secant (sec)
Cosecant (csc)
Cotangent (cot)

Answer:
15 a^2 + -10 a b
Step-by-step explanation:
Expand the following:
5 a (-2 b + 3 a)
Hint: | Distribute 5 a over -2 b + 3 a.
5 a (-2 b + 3 a) = 5 a (-2 b) + 5 a (3 a):
-2 5 a b + 5 3 a a
Hint: | Combine products of like terms.
5 a×3 a = 5 a^2×3:
5×3 a^2 - 2×5 a b
Hint: | Multiply 5 and 3 together.
5×3 = 15:
15 a^2 - 2×5 a b
Hint: | Multiply 5 and -2 together.
5 (-2) = -10:
Answer: 15 a^2 + -10 a b
