Define variable- 4.5x
Equation - 15+ 4.5x =42
Solution- x=6
15+ 4.5x =42
4.5x = 27
X=6
Answer:
Yes, the graph is a function.
Vertical line test proves so.
Answer:
a=15
Step-by-step explanation:
By pythagoras' theorem
25²=20²+a²
625=400+a² group like terms
a²=625-400
a²=225
therefore a=15
Answer:
Step-by-step explanation:
<em>Step 1: Determine quantity per liquid</em>
liquid 1=7/8 cup
liquid 2=9/10 cup
<em>Step 2: Derive expression to calculate total amount of mixture</em>
The expression below can be derived;
T=a+b
where;
T=total amount of mixture
a=total amount of liquid 1
b=total amount of liquid 2
In our case;
a=7/8 cup
b=9/10 cup
replacing;
T=(7/8)+(9/10)=1 31/40 cups
The total amount of mixture=1 31/40 cups
Answer:
10 times 16 = C
Step-by-step explanation:
c2 = a2 + b2 − 2ab cos C = 162 + 102 − 2(10)(16) cos 22°
