Remember to include the positive and negative roots


(7x-2)^2=256
sqrt both sides
7x-2=+/-16
add 2 to both sides
7x=2+/-16
divdide both sides by 7
x=(2+/-16)/7)

x=(2+16)/7=18/7=2 and 4/7
x=(2-16)/7=-14/7=-2

x=2 and 4/7 or -2

Why is it not possible to form a right triangle with the lengths 2, 4, and 7? *
puteri [66]

Answer:

No. The sum of 2 and 4 is less than 7.

Step-by-step explanation:

So, first, to create a triangle, the sum of two smallest sides have to be greater than the longest side, which is 2+4 = 6, and 6 is smaller than 7.

So, no, 2, 4, and 7 cannot create a triangle, to be exact a right triangle.

Hope this helps!!

3 Simple Questions! Help! 99 Points! Brainliest!
WARRIOR [948]

Answer:

1.       ridescost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25 then

1.25x+admission=y

if we solve

when x=25, y=43.75

1.25(25)+admission=43.75

31.25+admission=43.75

minus 31.25 from both sides

admission=12.50

a.

y=1.25x+12.5

b.

x is number of tickets and y is total cost

c. math, seriously, just read what is above option a (the one in the top of the answer)

if you're too lazy then:

ridescost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25 then

1.25x+admission=y

if we solve

when x=25, y=43.75


2.    

(a)  

m = (y2 - y1) / (x2 - x1) = (4 - 9)/(-2 - 8) = -5/(-10) = 1/2  

(b)  

y - y1 = m(x - x1)  

Using the first given point,  

y - 9 = (1/2)(x - 8)  

Using the second given point,

y - 4 = (1/2)(x + 2)

note they both simplify to  

y = (1/2)x + 5  

(c)  

y = (1/2)x + 5
