Answer:
(4,-2)
Step by Step Explanation:
Given equations are
y=x-6 eq(1)
3x+2y=8 eq(2)
Subtitute eq(1) into eq(2) we get
3x+2(x-6)=8
3x+2x-12=8
5x-12=8
Adding 12 on both side of equation we get
5x-12+12=8+12
5x=20
Dividing by 5 on both sides of equation we get
5x/5=20/5
x=4
Putting the value of in eq(1) we get
y=4-6
y=-2
The solution is (4,-2).
Answer:
The answer is (4,-2)
Step-by-step explanation:
y=x-6
3x+2y=8
3x+2(x-6)=8
3x+2x-12=8 Combine like terms
3x+2x-12+12=8+12 add 12 to both sides then combine
5x=20→ x=4
then plug it in to y=x-6→y=4-6→y=-2

Answer:
y^{n+4}
Step-by-step explanation:
(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Put both fractions into an improper fraction.... 33/7 - 13/7. then you subtract the numerators.. so its 20/7 or 2 6/7.
Answer:
<92
Step-by-step explanation:
Supplementary angles add up to 180°.
180-88=92
∠88° is supplementary to <92.
Answer:
x = -17/2 or -8.5
Step-by-step explanation:
-4x+8 = 42
Subtract 8 from each side
-4x+8-8 = 42-8
-4x = 34
Divide each side by -4
-4x/-4 = 34/-3
x = -17/2
x = -8.5
