To find the x-intercept, set y=0 and solve for x.
To find the y-intercept, set x=0 and solve for y.
7x+6y=21
x-int: y=0
7x+6(0)=21
7x=21
x=3
y-int: x=0
7(0)+6y=21
6y=21
y=21/6 or 7/2
        
             
        
        
        
Step-by-step explanation:
sin⁴ x − sin² x
Factor:
(sin² x) (sin² x − 1)
Pythagorean identity:
(1 − cos² x) (-cos² x)
Distribute:
-cos² x + cos⁴ x
cos⁴ x − cos² x
 
        
             
        
        
        
Answer:
400 (Sorry if its wrong.)
Step-by-step explanation:
50×3=150
5×40= 200
150+200= 350
350+50=400
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
1) Simplify 1/3 ( x - 10) to x-10/3.

2) Multiply both sides by 3.

Simplify 4 × 3 to 12.

4) Add 10 to both sides.

5) Simplify -12 + 10 to -2.

So, therefor, the answer is, x = -2.
