2 dollars. because when you divide 12 by 3 you get 4. so four eggs are one dollar.  so then 8 eggs would be 2 dollars

12 eggs = $3
8 eggs = (8÷12) × $3

hope this was helpful! :)

Help I need the answer so I won’t fail
anyanavicka [17]

Answer:

9

Step-by-step explanation:

We have to solve in order to find out if Sam is correct

Remember PEDMAS:

For Multiplication, division and addition, subtraction, do what appears first left to right

Parenthesis

Exponent

Division

Multiplication

Addition

Subtraction

16 - 18 + (2+1)+2^3

Parenthesis first: 2+1 = 3

16 - 18 + 3 + 2^3

Exponent next: 2^3 = 8

Subtraction (it's on the left) : 16-18 = -2

Addition: -2 + 3 = 1

Addition : 1 + 8 = 9

<em>Sam is not correct, the answer is </em><em>9, </em><em>not 16.</em>

Hope this helps :)

Have a great day!

For questions 1 and 2 graph the exponential function:<br> 1. y=3^x<br> 2. y=2(4.5)^x
Mumz [18]
First, we should know exponential formula, for example exp (LnA) =A, for all A>0, and as for logarythm, LnA^p=pLnA, for all A>0, and for all value of p
so y=3^x=exp[Ln(3^x)]=exp(xLn3), let's search the graph of f(x)=exp(xLn3) f is defined in R, and its teminals limits are 0, and + infinity, f' (x) = Ln3.exp(xLn3), it is positif for all value of x, the function is strictly increasing, f(0)=Ln3, please look at the figure 1
the same method with y=2(4.5)^x, we find y=exp[Ln (2(4.5)^x)]=
exp[Ln (2) +Ln(4.5)^x)], because (LnAB=LnA + LnB), so y=2.exp[Ln(4.5)^x)]=2.exp(x[Ln(4.5)]), which domain is R, nd its teminals limits are 0, and + infinity, f' (x)=2.Ln(4.5) exp(x[Ln(4.5)]), which is positif for all value of x, the function is strictly increasing,and then f(0)=2Ln(4.5)
please look the figure 2

Find the parametric equations for the line that passes through the points P (1,1,0) and Q (0,2,2).
sp2606 [1]

Answer:

The parametric equations for the given line are x=1-t, y=1+t and z=2t.

Step-by-step explanation:

Given information: P (1,1,0) and Q (0,2,2).

The parametric equation of line are

x=x_0+at

y=y_0+bt

z=z_0+ct

where, (x_0,y_0,z_0) is point on line and <a,b,c> is direction vector.

The line passes through the points P (1,1,0) and Q (0,2,2). So, the direction vector is

\overrightarrow{v}=

\overrightarrow{v}=

\overrightarrow{v}=

The direction vector is <-1,1,2>. So, a=-1, b=1 and c=2. The parametric equation of line are

x=1+(-1)t=1-t

y=1+(1)t=1+t

z=0+(2)t=2t

Therefore the parametric equations for the given line are x=1-t, y=1+t and z=2t.

What is the value of t?<br> 3.5(t+6)=7<br><br> A. -4<br> B. -0.25<br> C. 0.25<br> D. 4
Gelneren [198K]
A because when you distribute you get 3.5t + 21 = 7. Then subtract 21 from both sides to get 3.5t = -14. Then divide both sides by 3.5t to get -4.
