What is the decimal value of x in the equation 7x − 2 = 5x + 3?
Answers
Answer:
x= 2.5
Step-by-step explanation:
7x-5x = 2x
2x-2 = 3
3 + 2 = 5
2x=5
5/2 = 2.5
Answer: 5/2 or 2.5
Step-by-step explanation:
So first you add 2 to -2( crossing it out) and add 2 to 3. Then you simplify giving you the equation of 7x=5x+5.
Then subtract 5x from 7x and 5 giving you the equation of 2x=5.
Ounce done divide your equation by 2, giving you the answer if 5/2 or 2.5.
1. Which of the following is the standard form of y = (x – 3)(x – 7)?
a. y = (x + 5)2 – 21

d. y = (x – 5)2 + 28
A
B
Answers
9514 1404 393
Answer:
b. y = (x - 5)² - 4
Step-by-step explanation:
Here, we take "standard form" to mean "vertex form."
In the US, "standard form" would be ...
y = x² -10x +21
Vertex form is ...
y = (x -5)² -4 . . . . matches B

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. The angle of elevation of the tree from one position on a flat path from the tree is H=60°, and from a second position L=20 feet farther along this path it is B=50° What is the height of the tree?
Answers
Answer: 44.11 feets
Step-by-step explanation:
Using Pythagoras :
tan θ = opposite / Adjacent
Tan 60° = h / x
h = x tan 60 - - - (1)
tan 50° = h / (x + 20)
h = (x + 20) tan 50 - - - (2)
Equate (1) and (2)
x tan60 = (x + 20) tan 50
1.73205x = (x + 20) 1.19175
1.73205x = 1.19175x + 23.835
1.73205x - 1.19175x = 23.835
0.5403x = 23.835
x = 23.835 / 0.5403
x = 44.114380
Hence, height = 44.11 feets

Let U = {a, b, c, d, e, f, g}. Find the complement of the set A below.
A = {a, c, e, g}
Answers
Answer:
[tex]A' = \{b,d,f\}[/tex]
Step-by-step explanation:
Given
[tex]U = \{a, b, c, d, e, f, g\}[/tex]
[tex]A = \{a, c, e, g\}[/tex]
Required
Find the complement of A
The complement of A are elements in the universal set (U) but not in A.
In other words,
if [tex]A = \{a, c, e, g\}[/tex]
then A' are the elements other than a, c, e and g that are in the universal set
So
[tex]A' = \{b,d,f\}[/tex]
Where A' represents the complement
The angle bisectors of triangle XYZ meet at point P. What is PJ?
Answers
=======================================================
Explanation:
Segment PJ is perpendicular to segment YZ
So triangle PJZ is a right triangle with the known leg ZJ = 12, unknown leg PJ = x, and known hypotenuse PZ = 20.
Let's say a = 12, b = x, c = 20.
Use the Pythagorean theorem to find x
a^2 + b^2 = c^2
12^2 + x^2 = 20^2
144 + x^2 = 400
x^2 = 400-144
x^2 = 256
x = sqrt(256)
x = 16
Therefore segment PJ is 16 units long.
Side note: the angle bisectors won't always form 90 degree angles with the opposite sides. These angle bisectors are also altitude lines because of the 90 degree angles that form.

Answers
Answer:
Step-by-step explanation:
35 percent of total miles traveled (say T)is 252 miles.
(35/100) * T=252
T=(252*100)/35 => T=720 miles
So total distance the Ramirez family traveled during its vacation is 720 miles

Step-by-step explanation:
This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.
