To solve these types of problems, we need to break it down and see what each part represents.
(11) 3m
(12) j-10
(13) d+4
(14) 4p
All we must do is understand some basic keywords, such as times which represents multiplication, less which represents subtraction, and more which can represent addition or multiplication.<span />
Answer:
2.f(x)=2^4x
Step-by-step explanation:
16^x
We can rewrite 16 as 2^4
2^4^x
We know that a^b^c is equal to a^ (b*c)
so 2^(4*x)
2^(4x)
Answer:
<u>18°</u>
Step-by-step explanation:
sin 2x=cos zy
m(2x)=72°
cos(π/2-a)=sin a
cos(π/2-72°)=sin72°
cos18°=sin72°
=>m(zy)=18°
Answer:
Step-by-step explanation:
Multiply each # by 3 so 15 36 39
(15x36)/2=270
I'm sorry if its wrong.
Answer:
y=26, x=-3
Step-by-step explanation:
3x+y=17
3x+y-y=17-y
3x=17-y
Divide both sides by 3
Simplify
\frac{17-y}{3}+2y=49
\frac{17-y}{3}\cdot \:3+2y\cdot \:3=49\cdot \:3
17-y+6y=147
17+5y=147
17+5y-17=147-17
5y=130
\frac{5y}{5}=\frac{130}{5}
y=26
x=\frac{17-26}{3}
x=-3
