Which is not an equation of the line that passes through the points (1, 1) and (5, 5)?

Answers

Answer 1
Answer:

Answer:

Any equation of the line that is different from y=x is the solution to the problem.

Step-by-step explanation:

step 1

Find the slope of the line that passes through the points (1, 1) and (5, 5)

m=(5-1)/(5-1)=1

step 2

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have m=1

(x1,y1)=(1,1)

substitute

y-1=(1)(x-1)

y=x-1+1

y=x

therefore

Any equation of the line that is different from y=x is the solution to the problem.

How do I solve this?

Answers

area=LW
perimiter=2(L+W)

aera=36
P=25

36=LW
25=2(L+W)


25=2(L+W)
divide both sides by 2
12.5=L+W
minus W
12.5-W=L

sub for L
36=W(12.5-W)
36=12.5W-W^2
minus (12.5W-W^2) both sides
0=W^2-12.5W+36
use quadratic formula

if you have
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}

a=1
b=-12.5
c=36

W=\frac{-(-12.5)+/- \sqrt{(-12.5)^(2)-4(1)(36)} }{2(1)}
W=(12.5+/- √(156.25-144) )/(2)
W=(12.5+/- √(12.25) )/(2)
aprox
W=8 or 4.5

sub
12.5-W=L


12.5-8=L=4.5
12.5-4.5=L=8
either way

the dimentions are 4.5cm by 8 cm

Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes. Show your work?

Answers

A. likely

B. unlikely

C. There is a greater chance in picking to purple marbles because there are less of the white and more purple.

Hallie should spin the wheel because u have a greater chance of landing on a 5 then rolling two number cubes and hoping both number cubes come to equal 5.
two white marbles: probability first is white is \frac{2}{9} probability second is white given that the first is white is \frac{1}{8} again probability both happen is \frac{2}{9}\times \frac{1}{8}

The average adult human has approximately 2.5 X 10' red blood cells and 7 X 10' whiteblood cells. About how many times as great is the number of rea blood cells than the

Answers

Answer:

\large \boxed{r =\frac{\text{RBC}}{\text{WBC}};\,\text{400 times}}

Step-by-step explanation:

I think your missing numbers are

RBC = 2.5 × 10¹³ and  

WBC = 7    × 10¹⁰

This is a ratio question.

You are asked to find the ratio of RBCs to WBCs.

Let r = the ratio.

Then the equation for the ratio is

\mathbf{r} =\mathbf{ \frac{\text{RBC}}{\text{WBC}}}

Insert the values and do the division.

\begin{array}{rcl}r& =& \frac{\text{RBC}}{\text{WBC}}\n\n& =&(2.5 * 10^(13))/(7 * 10^(10))\n\n& =&\mathbf{400}\n\end{array}\n\text{The number of RBCs is $\large \boxed{\textbf{400 times}}$ as great as that of the WBCs.}

The one cost DVD is 16.98, and the cost of another DVD is 9.29. Ed estimated the cost of the two DVD to be about 27. Is his estimate higher or lower than the actual cost? Explain

Answers

Answer:

Higher

Step-by-step explanation:

16.98 + 9.29 = 26.27 < 27.00

26.27 is rounded to 26.10 or 26.00 so Ed's estimate is higher

there are 40 girls in a computer club. the ratio of girls to boys is 2 to 5. How many boys are in the club? complete this table to find out.

Answers

girsl=2 units
boys=5 units

girls=2units=40
divide 2
1 unit=20

boys=5 unit
5 times 20=100
