Answer:
7.8 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 48 = x/7
7 tan 48 = x
7.774287604 = x
To the nearest tenth
7.8 =x
This is written in slope intercept form, or y=mx+b, where m is slope and b is y intercept. Just look at the values that represent m and b to find the answer.
Slope: 3/4
Y intercept: -4
Ok
2x + y - z = 7
-2y +3z = -15
x + 2y - 5z = 17
combine 2nd 3rd
x - 2z = 2
x = 2z + 2
double first statement
4x + 2y - 2z = 14
combine with second statement
4x + z = -1
substitute 2z + 2 for x
8z + 8 + z = -1
combine like terms
9z + 8 = -1
sub 8 from both sides
9z = -9
divide both sides by 9
z = -1
substitute -1 for z in second statement
-2y - 3 = -15
add 3 to both sides
-2y = -12
divide both sides by -2
y = 6
substitute -1 for z into the fifth statement
x = -2 + 2
x = 0
Answer:
The value of x for the expression is 2
Step-by-step explanation:
Given algebraic expression as :
(4 + 6 x ) = 
x + 
( x + 9 )
Now, solving the given expression
Or, × 4 + × 6 x = x + x + × 9
Or, 
+ 
× x = x + x + 
or, 2 + 3 × x = 
+ 
+ 6
or, 2 + 3 × x = 
+ 6
or, 2 + 3 × x = 
+ 6
Or, 2 + 3 × x = x + 6
or, 3 x - x = 6 - 2
Or, 2 x = 4
∴ x =
I.e x = 2
Hence The value of x for the expression is 2 Answer
