Answer:
Step 1: Make x the subject by moving all x terms to one side;
a) 4x-2x=7+3
Step 2; solve the linear equation
2x=10
x=10/2
x = 5
b) 2x-7x = -14-6
-5x = -20
x = -20/-5
x= 4
Hope this helps :) ! I'd apreciate if you'd mark my answer brainliest because ive been on the same rank for quite a loong time :(
Answer: 75°
Step-by-step explanation:
Using the Base Angles Theorem, we can conclude that <ABC and <ACB are congruent. The angles of a triangle add up to 180 degrees so we can write this equation to solve for x:
x + 5 + 3x + 3x = 180
simplify
7x + 5 = 180
subtract 5 from both sides
7x = 175
divide each side by 7
x = 25
plug 25 in for x to find the angle measure
3(25) = 75
Answer:
{12,2}
Step-by-step explanation:
From the given graph it is clear that the initial point of the vector is (-5,0) and the terminal point (7,2).
If initial point of a vector is 
and terminal point is 
, then
Using this formula, we get
Using braces, we get
Therefore, the required vector is {12,2}.
