the graph would steeper, meaning more savings over time
Answer:
Step-by-step explanation:
5t - 3 = 14
5t=14+3
5t=17
t=17/5
t=3.4
let h=-12, k=-11 then
(x-h)^2 + (y-k)^2= r^2
(x+12)^2 + (y+11)^2 = 7^2
x^2 + 24x + 144 + y^2 + 22y + 121 = 49
x^2 + y^2 + 24x + 22y + 144+121-49= 0
x^2 + y^2 + 24x + 22y + 216 = 0 is the required eq
Answer:
v = 38
Step-by-step explanation:
A parallelogram is a quadrilateral in which both sides are the same. That means that 2v is equal to v + 38, and you can solve this. You would get that 2v = v + 38, which means that v = 38.
Answer:
The length of segment DC 33 units.
Step-by-step explanation:
Given:
The length of segment BC is 23 units.
To find:
Length of segment DC=?
Solution:
AB = 2x + 7
From the figure ,AB = BC
2x + 7 = 23
2x = 23 - 7
2x = 16
x = 8
In the Δ ABD and ΔCBD
(1) AB = BC(As given in the figure.)
(2) ∠DBA = ∠DBC = 90°
(3) BD = BD(Common side of both the triangle.)
Thus by using SAS congurence property .
Δ ABD ≅ ΔCBD
Thus AD = DC(Corresponding sides of the congurent triangle.)
Thus AD = 4x + 1
Substituting x = 8
AD =
AD = 32 + 1
AD = 33 unit
Thus AD = DC = 33 unit
