Evaluate the given function at x=1:
<span><span>f<span>(1)</span></span>=<span><span>log10</span><span>(1)</span></span>+2</span>
<span><span>f<span>(1)</span></span>=0+2</span>
<span><span>f<span>(1)</span></span>=<span>2</span></span>
<span><span>THIRD ONE</span></span>
X=number of girls.
y=number of boys.
We can suggest this system of equations:
2/7 x=3/5 y ⇒10x=21y ⇒x=21/10 y
y=x-165
We can solve this problem by substitution method:
x=(21/10)(x-165)
10x=21x-3465
10x-21x=-3465
-11x=-3465
x=-3465 /-11=315
y=x-165=315-165=150
Number of children=number of girls + number of boys
Number of children=315 +150=465
Answer: there were 465 children at the festival.
Answer:24
Step-by-step explanation:
any thing that is 5 and above rouned up
-b/2a will give you the axis of symmetry.
Aqui está um exemplo:
3/9-X/X = 2/9
Que é 3/9-1/2 = 9/9
Boa sorte!
