Im confused on how to use distance formula on this

Mathematics
1 answer:
zheka24 [161]2 years ago
4 0

Answer:

Not sure what you need ----see below

Step-by-step explanation:

Leg 1  of left triangle  = 8 units

Leg 2                          = 6

Hypotenuse               = 10  ( via Pythag theorem....or distance formula)

R triangle  Leg1 = 8 units

                  leg 2 = 6 units

        hypotenuse = 10 units      so the triangles are congruent by SSS

distance from right angle of triangle 1 ( at 0,0)   to

               right angle of triangle 2  ( at 6,-3)  

                     using<u> distance formula </u>

                      from 0,0  to 6, -3

              d^2 = ( 6-0)^2  + (-3 -0)^2

               d^2 = 45

                d = sqrt 45

What value is true of x makes this equation true 0.7x-5=0.2x+1
Sever21 [200]

Answer:

x=12

Step-by-step explanation:

First you make sure x is on both sides of the equation. So you do 0.7x-5-0.2x=0.2x+1-0.2x. Which just simplifies to 0.5x-5=1. You make sure x is the only thing on that side of the equation so you do 0.5x-5+5=1+5 which simplifies to 0.5x=6. Multiply the equation times 2 to just have x. x=12. The value that makes true of x is 12.

Y=109x <br>y=79x+2506<br> can some one solve both equations and a graph would be helpful plz
Amiraneli [1.4K]

Answer:

x ≈ 83.533

y = 9105.13

Step-by-step explanation:

Step 1: Substitution

109x = 79x + 2506

30x = 2506

x = 83.533

Step 2: Plug <em>x</em> in

y = 109(83.533)

y = 9105.13

23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer

24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)

25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)

26) was done correctly and (D) is the correct answer

27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)
